# CPO Advisor
Strategic product leadership. Vision, portfolio, PMF, org design. Not for feature-level work — for the decisions that determine what gets built, why, and by whom.
## Keywords
CPO, chief product officer, product strategy, product vision, product-market fit, PMF, portfolio management, product org, roadmap strategy, product metrics, north star metric, retention curve, product trio, team topologies, Jobs to be Done, category design, product positioning, board product reporting, invest-maintain-kill, BCG matrix, switching costs, network effects
## Quick Start
### Score Your Product-Market Fit
```bash
python scripts/pmf_scorer.py
```
Multi-dimensional PMF score across retention, engagement, satisfaction, and growth.
### Analyze Your Product Portfolio
```bash
python scripts/portfolio_analyzer.py
```
BCG matrix classification, investment recommendations, portfolio health score.
## The CPO's Core Responsibilities
The CPO owns three things. Everything else is delegation.
| Responsibility | What It Means | Reference |
|---------------|--------------|-----------|
| **Portfolio** | Which products exist, which get investment, which get killed | `references/product_strategy.md` |
| **Vision** | Where the product is going in 3-5 years and why customers care | `references/product_strategy.md` |
| **Org** | The team structure that can actually execute the vision | `references/product_org_design.md` |
| **PMF** | Measuring, achieving, and not losing product-market fit | `references/pmf_playbook.md` |
| **Metrics** | North star → leading → lagging hierarchy, board reporting | This file |
## Diagnostic Questions
These questions expose whether you have a strategy or a list.
**Portfolio:**
- Which product is the dog? Are you killing it or lying to yourself?
- If you had to cut 30% of your portfolio tomorrow, what stays?
- What's your portfolio's combined D30 retention? Is it trending up?
**PMF:**
- What's your retention curve for your best cohort?
- What % of users would be "very disappointed" if your product disappeared?
- Is organic growth happening without you pushing it?
**Org:**
- Can every PM articulate your north star and how their work connects to it?
- When did your last product trio do user interviews together?
- What's blocking your slowest team — the people or the structure?
**Strategy:**
- If you could only ship one thing this quarter, what is it and why?
- What's your moat in 12 months? In 3 years?
- What's the riskiest assumption in your current product strategy?
## Product Metrics Hierarchy
```
North Star Metric (1, owned by CPO)
↓ explains changes in
Leading Indicators (3-5, owned by PMs)
↓ eventually become
Lagging Indicators (revenue, churn, NPS)
```
**North Star rules:** One number. Measures customer value delivered, not revenue. Every team can influence it.
**Good North Stars by business model:**
| Model | North Star Example |
|-------|------------------|
| B2B SaaS | Weekly active accounts using core feature |
| Consumer | D30 retained users |
| Marketplace | Successful transactions per week |
| PLG | Accounts reaching "aha moment" within 14 days |
| Data product | Queries run per active user per week |
### The CPO Dashboard
| Category | Metric | Frequency |
|----------|--------|-----------|
| Growth | North star metric | Weekly |
| Growth | D30 / D90 retention by cohort | Weekly |
| Acquisition | New activations | Weekly |
| Activation | Time to "aha moment" | Weekly |
| Engagement | DAU/MAU ratio | Weekly |
| Satisfaction | NPS trend | Monthly |
| Portfolio | Revenue per product | Monthly |
| Portfolio | Engineering investment % per product | Monthly |
| Moat | Feature adoption depth | Monthly |
## Investment Postures
Every product gets one: **Invest / Maintain / Kill**. "Wait and see" is not a posture — it's a decision to lose share.
| Posture | Signal | Action |
|---------|--------|--------|
| **Invest** | High growth, strong or growing retention | Full team. Aggressive roadmap. |
| **Maintain** | Stable revenue, slow growth, good margins | Bug fixes only. Milk it. |
| **Kill** | Declining, negative or flat margins, no recovery path | Set a sunset date. Write a migration plan. |
## Red Flags
**Portfolio:**
- Products that have been "question marks" for 2+ quarters without a decision
- Engineering capacity allocated to your highest-revenue product but your highest-growth product is understaffed
- More than 30% of team time on products with declining revenue
**PMF:**
- You have to convince users to keep using the product
- Support requests are mostly "how do I do X" rather than "I want X to also do Y"
- D30 retention is below 20% (consumer) or 40% (B2B) and not improving
**Org:**
- PMs writing specs and handing to design, who hands to engineering (waterfall in agile clothing)
- Platform team has a 6-week queue for stream-aligned team requests
- CPO has not talked to a real customer in 30+ days
**Metrics:**
- North star going up while retention is going down (metric is wrong)
- Teams optimizing their own metrics at the expense of company metrics
- Roadmap built from sales requests, not user behavior data
## Integration with Other C-Suite Roles
| When... | CPO works with... | To... |
|---------|-------------------|-------|
| Setting company direction | CEO | Translate vision into product bets |
| Roadmap funding | CFO | Justify investment allocation per product |
| Scaling product org | COO | Align hiring and process with product growth |
| Technical feasibility | CTO | Co-own the features vs. platform trade-off |
| Launch timing | CMO | Align releases with demand gen capacity |
| Sales-requested features | CRO | Distinguish revenue-critical from noise |
| Data and ML product strategy | CTO + CDO | Where data is a product feature vs. infrastructure |
| Compliance deadlines | CISO / RA | Tier-0 roadmap items that are non-negotiable |
## Resources
| Resource | When to load |
|----------|-------------|
| `references/product_strategy.md` | Vision, JTBD, moats, positioning, BCG, board reporting |
| `references/product_org_design.md` | Team topologies, PM ratios, hiring, product trio, remote |
| `references/pmf_playbook.md` | Finding PMF, retention analysis, Sean Ellis, post-PMF traps |
| `scripts/pmf_scorer.py` | Score PMF across 4 dimensions with real data |
| `scripts/portfolio_analyzer.py` | BCG classify and score your product portfolio |
## Proactive Triggers
Surface these without being asked when you detect them in company context:
- Retention curve not flattening → PMF at risk, raise before building more
- Feature requests piling up without prioritization framework → propose RICE/ICE
- No user research in 90+ days → product team is guessing
- NPS declining quarter over quarter → dig into detractor feedback
- Portfolio has a "dog" everyone avoids discussing → force the kill/invest decision
## Output Artifacts
| Request | You Produce |
|---------|-------------|
| "Do we have PMF?" | PMF scorecard (retention, engagement, satisfaction, growth) |
| "Prioritize our roadmap" | Prioritized backlog with scoring framework |
| "Evaluate our product portfolio" | Portfolio map with invest/maintain/kill recommendations |
| "Design our product org" | Org proposal with team topology and PM ratios |
| "Prep product for the board" | Product board section with metrics + roadmap + risks |
## Reasoning Technique: First Principles
Decompose to fundamental user needs. Question every assumption about what customers want. Rebuild from validated evidence, not inherited roadmaps.
## Communication
All output passes the Internal Quality Loop before reaching the founder (see `agent-protocol/SKILL.md`).
- Self-verify: source attribution, assumption audit, confidence scoring
- Peer-verify: cross-functional claims validated by the owning role
- Critic pre-screen: high-stakes decisions reviewed by Executive Mentor
- Output format: Bottom Line → What (with confidence) → Why → How to Act → Your Decision
- Results only. Every finding tagged: 🟢 verified, 🟡 medium, 🔴 assumed.
## Context Integration
- **Always** read `company-context.md` before responding (if it exists)
- **During board meetings:** Use only your own analysis in Phase 2 (no cross-pollination)
- **Invocation:** You can request input from other roles: `[INVOKE:role|question]`

# PMF Playbook
How to find product-market fit, measure it, and not lose it. Steps, not theory.
---
## What PMF Actually Is
PMF is when a product pulls users in rather than pushing them. Signals:
- Users find the product without you telling them about it
- They're upset when it doesn't work
- They bring their colleagues, their friends, their boss
- They build workarounds when a feature is missing
PMF is not:
- Users saying they like it
- A good NPS score with flat growth
- Enterprise customers who are locked in but churning at contract end
---
## Step 1: Find Your Best Customers First
Before measuring PMF across everyone, find the segment where PMF is strongest.
**How:**
1. Export a list of all churned users and all retained users (D90+)
2. Identify 5-10 attributes to compare: company size, industry, job title, signup source, first action taken, time to first value
3. Find the attributes that are over-represented in retained vs. churned
4. That's your highest-PMF segment
**This is not an analytics project.** Call 10 retained power users. Ask:
- "What were you doing before you found us?"
- "What would you use if we shut down tomorrow?"
- "Who else in your life has this problem?"
The segment where this conversation is easy and the answers are specific — that's where your PMF is.
---
## Step 2: Measure the Three PMF Signals
Run all three. They measure different things. One signal without the others is misleading.
### Signal 1: Retention Curves
**Method:**
1. Cohort users by week or month of first use
2. Calculate % still active at D1, D7, D14, D30, D60, D90
3. Plot the curve for each cohort
**Interpretation:**
| Curve Shape | What It Means |
|-------------|--------------|
| Drops to zero | No PMF. Product doesn't solve a recurring problem. |
| Drops and keeps dropping | Weak PMF. Some people find value, but not enough to keep coming back. |
| Drops then flattens above 0 | PMF signal. A core group finds ongoing value. |
| Flattens higher with each newer cohort | PMF improving. You're learning. |
**Benchmarks:**
| Segment | D30 Retention (PMF threshold) | D90 Retention (strong PMF) |
|---------|-------------------------------|---------------------------|
| Consumer | > 20% | > 10% |
| SMB SaaS | > 40% | > 25% |
| Enterprise SaaS | > 60% | > 45% |
| Marketplace (buyers) | > 30% | > 20% |
| PLG (free-to-paid) | > 25% free D30, > 50% paid D30 | > 15% free D90 |
**If retention is below threshold:**
- Don't run more acquisition. You'll just churn faster.
- Find the users who ARE retained. Understand why. Build for them.
---
### Signal 2: Sean Ellis Test
Survey users with one question: "How would you feel if you could no longer use [Product]?"
**Answers:**
- Very disappointed
- Somewhat disappointed
- Not disappointed (it really isn't that useful)
- N/A — I no longer use [Product]
**Scoring:**
- Count only "very disappointed" responses
- Divide by total non-churned respondents
- PMF threshold: **> 40% "very disappointed"**
**Sample size requirement:** Minimum 40 responses. Under 40, the signal is noisy.
**When to run it:**
- When you have 100-500 active users
- Quarterly for ongoing tracking
- After major product changes
**What to do with "somewhat disappointed":**
Don't lump them with "very disappointed." The delta between "somewhat" and "very" is where your retention problem lives. Interview people in the "somewhat" group. What's missing? Why only somewhat?
**When score is 20-35%:** You have a segment with PMF. Find them. Ask what they love. Run a separate survey for just that segment.
**When score is < 20%:** Your core value proposition isn't working. This is not a retention tactics problem. Revisit the fundamental problem you're solving.
---
### Signal 3: Organic Growth and Referral
**Metric:** % of new signups that came from existing user referral, word of mouth, or organic search — without a paid incentive.
**Threshold:** > 20% of new users are coming organically without incentive programs.
**How to measure:**
1. Tag signup source: paid, organic search, referral (with referral code), direct/dark social
2. Track monthly. Is the organic % trending up or stable?
3. Interview organic signups: "How did you hear about us?" (don't trust the dropdown)
**Why this matters:** Paid growth can mask the absence of PMF. You can buy users who churn. You can't buy users who tell their friends.
---
## Step 3: Run PMF Experiments (Pre-PMF)
If you're below thresholds, don't optimize — experiment. The goal is to find the version of the product where at least a small segment has PMF.
### The PMF Experiment Loop
```
1. Pick one customer segment + one hypothesis about their job to be done
2. Remove everything from the product that doesn't serve that job
3. Run a 4-week cohort with only that segment
4. Measure retention + Sean Ellis for that cohort
5. If PMF signal: this is your beachhead. Double down.
If no signal: new hypothesis. Repeat.
```
**Time box:** Each experiment 4-8 weeks. If you're running experiments for 18+ months with no signal, revisit the problem space, not just the solution.
### What to Change
| Lever | Change | Expected Impact |
|-------|--------|-----------------|
| Target segment | Narrow ICP from "all companies" to "Series A SaaS" | Faster learning, higher retention |
| Core job | Reframe from feature-benefit to outcome-benefit | Better product decisions |
| Onboarding | Remove steps to time-to-value | D1 retention up |
| Pricing | Move from per-seat to per-outcome | Align incentives with value |
| Channel | Switch from outbound to PLG | Different segment discovers product |
---
## Step 4: Validate PMF (Post-Signal, Pre-Scale)
Congratulations, you have a retention curve that flattens. Before you scale:
**Validate that it's real:**
- Can you acquire more of the same customers? (Test CAC at 2x current volume)
- Do the retained users expand? (Are they buying more seats, upgrading?)
- Is the NPS from retained users > 40?
- Are they forgiving of bugs and slowness? (Love, not tolerance)
**Validate the unit economics:**
- LTV / CAC > 3x (for SaaS)
- Payback period < 18 months
- Gross margin > 60% (SaaS), > 40% (marketplace)
**The danger zone:** Convincing yourself you have PMF before economics are viable. High retention with terrible unit economics is not a business — it's a hobby that grows.
---
## PMF by Business Model
### B2B SaaS
**Primary signal:** D90 retention > 45% in target segment.
**Secondary signals:**
- NPS from retained users > 50
- Expansion revenue from retained accounts (NRR > 110%)
- Sales cycle shortening as word-of-mouth increases
**PMF finding strategy:**
- Start with one vertical, not the whole market
- Get 3-5 reference customers who use it daily and refer others
- Don't expand segment until you can replicate the reference case
**Common false signals:**
- Retained users who are locked in by contract, not value
- Expansion revenue from upselling, not from organic growth
- High satisfaction survey scores with flat usage data
---
### B2C / Consumer
**Primary signal:** D30 retention > 20%, with a flat or rising tail at D90.
**Secondary signals:**
- DAU/MAU ratio > 20% (daily habit product: > 40%)
- Session depth (users exploring multiple features, not one-and-done)
- Organic referral rate > 20% of new installs
**PMF finding strategy:**
- Consumer PMF is about habit formation — which behavior do you own in a user's day?
- Find the "aha moment" (the action that predicts retention). Build everything to get users there faster.
- Segment ruthlessly — consumer PMF is often strong in one demographic, weak in others.
**Common false signals:**
- High D1 retention from email campaigns that re-engage dormant users
- Good NPS from vocal users who are power users, not typical users
- Media buzz driving installs from wrong audience
---
### Marketplace
**Primary signal:** Successful transaction rate and repeat buyer rate.
**Secondary signals:**
- Supply-side retention (sellers/providers coming back)
- Liquidity score: % of demand requests matched within acceptable time
- Referral: both sides sending others
**PMF challenge:** You have two customers (supply and demand). PMF can exist on one side and not the other.
**PMF finding strategy:**
- Start with constrained geography or category — don't try to be national before local works
- Measure GMV per cohort, not just transaction count
- Find the "magic moment" for both buyer and seller. Optimize for both.
---
### PLG (Product-Led Growth)
**Primary signal:** Free-to-paid conversion rate + paid retention.
**Secondary signals:**
- Time to activation (reaching the "aha moment" in free tier)
- PQL (product-qualified lead) conversion to paid
- Team invites from individual users (virality coefficient)
**PMF finding strategy:**
- The free tier must have genuine value — not a crippled trial
- Track activation milestone (the action that predicts conversion)
- Optimize activation before conversion — conversion optimizations don't work if nobody activates
---
## After PMF: The Scaling Trap
Most companies that fail after PMF weren't ready to scale. They scaled the wrong thing.
### The Scaling Trap
You have PMF with segment A. You hire sales and start selling to segment B. Segment B doesn't retain. NPS drops. Engineers chase segment B feature requests. Segment A users feel abandoned.
**This is the most common way early-stage companies die after PMF.**
### What to Do After PMF
**First 90 days after confirming PMF:**
1. Document your best customer profile in extreme detail
2. Build the playbook to replicate the reference customer, not to expand the ICP
3. Hire sales to replicate, not to expand
4. Instrument everything — you need to know what's driving retention for every new cohort
5. Don't launch new features. Remove friction from the path that's already working.
**The expansion question:** Only expand ICP when:
- You can replicate the reference customer at 3x volume with same retention
- CAC is declining (word of mouth in the reference segment)
- You've exhausted density in the reference segment
**Don't expand ICP to save the business.** Expanding ICP when retention is declining is panic, not strategy.
---
## How to Know When PMF Is Slipping
PMF is not a binary state. It can degrade. Watch for:
| Signal | What's Happening | Response |
|--------|-----------------|----------|
| D30 retention declining across cohorts | Product changes or market change are eroding value | Run Sean Ellis test immediately. Interview churned users. |
| Sean Ellis score dropping | Users less passionate about the product | Feature gap opening. Competitive pressure. |
| NPS dropping for retained users | Power users seeing degraded experience | Product quality or performance issues. |
| Organic referral rate declining | Satisfied users less enthusiastic | Product becoming commoditized. Moat eroding. |
| Support tickets shifting from feature requests to bug reports | Technical debt catching up | Engineering quality investment needed. |
| Sales cycles lengthening | ICP no longer self-evident. Positioning drift. | Re-run positioning exercise. Sharpen ICP. |
**The PMF quarterly check:**
Run Sean Ellis test every quarter. Track D30 retention by cohort every month. Put both on the CPO dashboard. These are your vital signs.
---

# Product Org Design Reference
How to structure, hire, and run product organizations at different stages. No generic advice — stage-specific, role-specific, and honest about what breaks.
---
## 1. Team Topologies for Product Orgs
Matthew Skelton and Manuel Pais defined four team types. Here's how they map to product organizations.
### Four Team Types
#### Stream-Aligned Teams
Own a continuous flow of customer-facing work. They take problems all the way from discovery to delivery to measurement.
**Product org equivalent:** Feature teams, growth teams, customer journey teams.
**Characteristics:**
- Long-lived (not project teams)
- Full-stack: PM + Designer + 3-7 Engineers + QA
- Can deploy independently without asking another team
- Own their backlog, their metrics, their outcomes
**Health signals:**
- Ships without waiting on other teams more than 20% of the time
- Can define their own north star and trace it to company metric
- PMs spend > 50% of time in discovery, not coordination
**Warning signs:**
- Every sprint has "dependencies" blocking progress
- Team has PMs but engineers don't know the customer problems
- Roadmap is handed to them, not co-created
#### Platform Teams
Build and maintain shared capabilities so stream-aligned teams don't reinvent them.
**Product org equivalent:** Platform product team, internal tools, shared infrastructure.
**Characteristics:**
- Serve internal customers (other teams), not end users directly
- Measure success by stream-aligned team velocity, not feature count
- Self-service is the goal — stream teams should be unblocked without filing tickets
**Health signals:**
- Stream-aligned teams can do 80% of their work without filing a ticket to platform
- Platform has a public API and documentation, not just engineers who know how it works
- Platform team metrics include "number of teams using X without assistance"
**Warning signs:**
- Platform team has a 6-week SLA for new features
- Stream teams fork the platform to avoid waiting
- Platform team's backlog is driven by platform's own ideas, not stream team pain
**The platform product manager role:**
Platform PMs are not feature PMs. They manage internal customers. Key skills:
- Developer experience empathy (they're building for engineers)
- API and infrastructure intuition (you can't PM what you don't understand)
- Saying "no" gracefully when requests are misuses of the platform
#### Enabling Teams
Temporarily help other teams upskill in a domain. Not permanent.
**Product org equivalent:** UX research team, data literacy evangelism, accessibility experts.
**Duration:** Time-boxed. 3-6 months. Then they leave and the skill stays.
**Failure mode:** Enabling teams that never leave become coordination bottlenecks.
#### Complicated Subsystem Teams
Deep expertise required. Minimal interaction.
**Product org equivalent:** ML/AI product team, compliance product, payments, internationalization engine.
**Characteristics:**
- Specialists who can't be split across stream-aligned teams
- Interact via well-defined interface, not collaboration
- Have their own PM who understands the domain deeply
---
## 2. Org Models at Each Stage
### Pre-Seed / Seed (1-20 engineers)
**Structure:** Founder/CEO or founder/CTO is the PM. Maybe one hired PM at 15+ engineers.
**Don't build:** Process, specialization, hierarchy.
**Do build:** Direct customer access, fast iteration loops, written learning from every experiment.
**PM role at this stage:**
- Not shipping features. Talking to customers.
- Not writing specs. Running experiments.
- Not managing engineers. Being managed alongside them.
**Hiring mistake:** Hiring a "process PM" who builds Jira templates before you have PMF.
---
### Series A (20-60 engineers)
**Structure:** 2-4 PMs, organized by product area or customer journey.
```
CPO / Head of Product
├── PM — Core Product (the thing customers pay for)
├── PM — Growth / Acquisition (how more customers get there)
└── PM — Platform (as soon as engineering says they need it)
```
**What you add:** One embedded designer. Analytics shared.
**First PM hire criteria:**
- Has shipped something users use, not just wrote a spec
- Comfortable with ambiguity and no process
- Will talk to customers without being asked
- Understands the technical constraints intuitively
**What breaks at Series A:**
- Verbal communication stops working. First thing to document: the roadmap, the north star, who decided what.
- Engineers start asking "why are we building this?" — good. Answer it.
- Customer requests multiply faster than capacity. You need a prioritization framework.
---
### Series B (60-150 engineers)
**Structure:** 4-8 PMs, head of product, first design hire, embedded or dedicated analytics.
```
CPO
├── Head of Product
│ ├── PM — [Team 1] (stream-aligned)
│ ├── PM — [Team 2] (stream-aligned)
│ ├── PM — [Team 3] (stream-aligned)
│ └── PM — Platform (if engineering > 40)
├── Head of Design (or Senior Designer × 2-3)
└── Analytics (shared, or 1 embedded per team)
```
**What you add at Series B:**
- Head of Product (frees CPO from backlog, runs PM team)
- First Head of Design hire (if not already)
- Dedicated growth team (PLG or acquisition)
**What breaks at Series B:**
- PMs start optimizing their own team's metrics instead of company metrics
- Design and engineering don't talk until sprint planning
- Data team is a ticket queue — PMs can't self-serve
**Fix:** OKR alignment across teams. Design in discovery, not in handoff. Analytics tool self-serve access for every PM.
---
### Series C (150-400 engineers)
**Structure:** 8-15 PMs, multiple PM leads / directors, specialized functions.
```
CPO
├── VP / Director of Product
│ ├── PM Lead — [Product Line 1]
│ │ ├── PM
│ │ └── PM
│ ├── PM Lead — [Product Line 2]
│ │ ├── PM
│ │ └── PM
│ └── PM Lead — Platform
├── Head of Design
│ ├── UX Design
│ ├── Product Design
│ └── UX Research
├── Head of Data / Analytics
│ ├── Product Analytics
│ └── Data Science
└── Head of Product Operations
```
**What you add at Series C:**
- PM leads / directors (PMs managing PMs)
- Dedicated UX research
- Head of Product Operations (roadmap tooling, PM hiring, analytics standards, product community)
- Possible Chief of Staff (Product)
**What breaks at Series C:**
- Coordination overhead becomes the primary job
- PMs become project managers managing handoffs instead of product decisions
- Consistency across teams: 5 different ways to write a spec, 5 different analytics setups
- CPO loses touch with customers
**Fix:** Product principles (written, opinionated, used in reviews). Embedded researchers. Regular CPO customer calls (monthly minimum). Product ops to solve consistency without bureaucracy.
---
## 3. PM:Engineer Ratios
### By Stage
| Stage | Engineers | PMs | Ratio | Notes |
|-------|-----------|-----|-------|-------|
| Seed | 5 | 0-1 | 1:5 | Founder PM common |
| Series A | 20-40 | 2-4 | 1:8 | First real PMs |
| Series B | 60-100 | 5-8 | 1:10 | Platform PM emerges |
| Series C | 150-250 | 12-18 | 1:12 | PM leads required |
| Growth | 300+ | 20+ | 1:12-15 | Specialization high |
### By Team Type
| Team Type | Ratio | Rationale |
|-----------|-------|-----------|
| Stream-aligned (feature) | 1:6-8 | High discovery work, many stakeholders |
| Growth / PLG | 1:8-10 | High experimentation, more autonomy per engineer |
| Platform | 1:10-15 | Lower ambiguity, more self-directed engineers |
| Complicated subsystem (ML, payments) | 1:12-20 | Technical direction from engineers, PM is translator |
**The ratio trap:** These are guidelines, not targets. A great PM in a bad org with 12 engineers accomplishes less than a great PM with 8 in a healthy org. Fix the org before optimizing the ratio.
---
## 4. When to Hire Key Roles
### Head of Design
**Not yet signal:**
- Fewer than 2 full-time designers
- Product is primarily technical (API-first, developer tool with no GUI)
- Design is consistently described as "not a blocker"
**Hire now signal:**
- Design has become a coordination problem (who reviews what? which system? what's the standard?)
- You have 3+ designers and they're inconsistent
- CPO is spending significant time on design decisions
- Customers cite UX as a blocker to adoption
**What this person does:**
- Builds and maintains the design system
- Runs UX research as a function, not one-off projects
- Hires and grows the design team
- Keeps designers from becoming pixel-pushers and keeps them in discovery
**Wrong hire:** A senior IC who can't build process and isn't excited about it.
---
### Head of Data / Analytics
**Not yet signal:**
- < 5 PMs, data team shared with engineering
- You don't have product analytics instrumentation yet (worry about that first)
- Product metrics are reviewed monthly and nobody acts on them
**Hire now signal:**
- PMs are filing tickets for basic metric questions (sign that data team is a bottleneck)
- Multiple products with different tracking setups — no common definitions
- You want to run experiments but don't have infrastructure
- Leadership is making product decisions without data (not from choice — from access)
**What this person does:**
- Defines the event taxonomy and enforces it
- Builds self-serve analytics capability for PMs
- Runs A/B testing infrastructure
- Partners with PMs on experiment design (before launch, not after)
**Wrong hire:** A pure data scientist who can't build product analytics infrastructure and doesn't want to.
---
### Head of Product Operations
**Hire when you have:**
- 8+ PMs with inconsistent processes
- CPO spending > 30% of time on internal coordination
- No standard for roadmap tools, prioritization, or PM onboarding
- Product team can't answer "what are all teams working on this quarter?" without a 2-hour meeting
**What this person does:**
- PM onboarding and development program
- Roadmap and tooling standards (Jira, Linear, Notion — pick one and enforce it)
- Data pipelines from product to leadership (weekly metrics, OKR tracking)
- PM hiring and interview process
- Voice of product org in cross-functional coordination
**What this person does NOT do:**
- Drive product strategy (that's the CPO)
- Manage PMs (that's the Head of Product or PM leads)
- Own analytics (that's Head of Data)
---
## 5. The Product Trio
Every product team should have three roles working together from day one of discovery:
```
Product Manager → What to build and why
Product Designer → How users experience it
Tech Lead / Engineer → How to build it sustainably
```
### How the Trio Actually Works
**Discovery (weeks 1-2 of any new initiative):**
- All three in user interviews together
- All three reviewing competitive products
- All three in problem framing sessions
- Output: Opportunity, not solution
**Ideation (days):**
- All three generating solutions
- Designer prototypes 2-3 options
- Engineer provides feasibility gut check on each
- PM synthesizes against strategy
- Output: Prototype for testing
**Testing (days):**
- Designer and PM run tests (engineer optional but encouraged)
- Tests with 5-8 real customers
- All three review findings together
- Output: Decision: build, iterate, or kill
**Delivery (sprints):**
- PM writes acceptance criteria (what done looks like from user perspective)
- Engineer owns implementation
- Designer owns QA for experience quality
- All three do final review before release
### Trio Anti-Patterns
| Anti-Pattern | What It Looks Like | Why It Fails |
|-------------|-------------------|--------------|
| **PM → Designer → Engineer** | Waterfall disguised as agile | Late discovery of infeasibility and poor UX |
| **Engineer-led** | Engineers propose solutions, PM and designer polish | Builds technically correct thing nobody wants |
| **PM-led dictation** | PM writes detailed spec, team executes | Team has no context, can't make good trade-offs |
| **Designer detached** | Designers design in isolation, present to engineers | Beautiful mockup that's 8x harder to build than alternative |
| **No research** | Trio invents problems and solutions in a conference room | Building for themselves |
---
## 6. Remote vs. Co-located Product Teams
The debate is mostly settled. Here's what actually matters:
### What Changes with Remote
| Activity | Co-located | Remote | Fix |
|----------|-----------|--------|-----|
| Discovery sync | Organic, hallway | Requires scheduling | Daily async standups + weekly sync |
| Whiteboarding | Easy | Friction | Figma, Miro — async-first artifacts |
| Design review | Walk over | Calendar invite | Record reviews; written decisions |
| Relationship building | Osmotic | Deliberate | Regular 1:1s, team rituals, offsites |
| Onboarding | Shadow in person | Document-heavy | Written playbooks + buddy system |
| Difficult conversations | Easier in person | Harder | Default to video, not Slack |
### The Async-First Product Team
Works well remote IF:
- Decisions are written (Notion, Confluence, not Slack threads)
- Roadmaps are accessible to everyone without a meeting
- Product reviews are recorded and linked
- Discovery artifacts are shared before the meeting, discussed in the meeting
- 1:1s are weekly and actual (not "let's skip this week")
**What doesn't survive async:**
- Ambiguous ownership
- Verbal agreements (write it down or it didn't happen)
- Teams where "PM wrote the spec" is the only documentation
### Remote Product Org Practices
**Weekly Cadence:**
```
Monday: Async kickoff — each team posts week's focus + blockers
Tuesday: Product trio sync (30 min, per team)
Wednesday: CPO / Head of Product 1:1s
Thursday: Cross-team PM sync (30 min, rotating topics)
Friday: Async retrospective notes + week summary
```
**Monthly:**
- Full product org sync (all PMs, designers, heads)
- CPO product review (each team presents one initiative)
- Metrics review (company + team level)
**Quarterly:**
- In-person or virtual offsite
- Strategy and OKR setting
- Individual growth conversations
---
## Quick Reference
| Stage | Structure | First Hire Priority |
|-------|-----------|-------------------|
| Seed | Founder PM | Generalist PM with customer instincts |
| Series A | 2-3 PMs, flat | First real PM, owns a product area |
| Series B | Head of Product, 4-8 PMs | Head of Design |
| Series C | Org layers, PM leads | Head of Data + Product Ops |
| Growth | Full specialization | Chief of Staff (Product) |
**PM:Engineer ratio target by stage:**
Seed 1:5 → Series A 1:8 → Series B 1:10 → Series C 1:12 → Growth 1:15
**Three things that fix most product org problems:**
1. Stream-aligned teams with full-stack ownership (PM + Design + Eng)
2. OKRs that cascade from company to team to individual
3. Product trio in discovery, not just delivery

# Product Strategy Reference
Frameworks for product vision, competitive positioning, portfolio management, and board reporting. No theory — only what CPOs actually use.
---
## 1. Vision Frameworks
### Jobs to Be Done (JTBD)
JTBD is not a feature framework. It's a way to understand *why* customers hire your product and under what circumstances.
**The core insight:** People don't want your product. They want to make progress in their lives, and they hire your product to help. When you understand the job, you understand competition differently.
#### Conducting JTBD Interviews
**Who to interview:** Recent buyers and recent churners. Not power users — they're already converted.
**The interview script (condensed):**
```
1. "Walk me through the last time you [started using / stopped using] this product."
2. "What were you doing the day before you decided?"
3. "What else did you consider?"
4. "What almost stopped you from doing it?"
5. "Now that you're using it, what does your day look like differently?"
```
**What you're extracting:**
- **Functional job:** What task are they accomplishing?
- **Emotional job:** How do they feel during and after?
- **Social job:** How are they perceived?
- **Timeline:** What triggered the switch? (the "push" from old solution + "pull" toward new one)
- **Anxieties:** What almost prevented adoption?
- **Competing solutions:** What are they comparing you to, including "do nothing"?
#### JTBD Output: The Job Story
Format better than "user story" for strategic decisions:
```
When [situation],
I want to [motivation/job],
So I can [expected outcome].
```
**Example (healthcare scheduling):**
```
When I'm trying to coordinate my parent's care from another city,
I want to see their upcoming appointments and have someone confirm changes,
So I can feel confident they won't miss critical treatments.
```
This is a different product than "schedule management software." The strategic implications — care coordination, family access, confirmation workflows — flow from the job.
#### JTBD → Product Strategy
| Job Insight | Strategic Implication |
|-------------|----------------------|
| Job is episodic (quarterly) | Engagement model must reach them before they need it |
| Job is habitual (daily) | DAU/MAU matters; build for habit formation |
| Job has high stakes | Trust and reliability > features; invest in onboarding + support |
| Job is social | Network effects possible; virality is structural, not a campaign |
| Job is delegated (done for someone else) | Two users: the buyer and the beneficiary. Design for both. |
---
### Category Design
If you're fighting for share in an existing category, you're playing defense on someone else's field.
**Category design premise:** Companies that define the category typically capture 76% of the market cap of that category. Name the category, own it.
#### The Category Design Process
**Step 1: Name the problem, not the solution.**
```
Wrong: "We make AI-powered customer support software."
Right: "The support team doesn't need more tickets. They need fewer problems."
```
**Step 2: Define the enemy.**
The enemy is the *old way* of solving the problem, not a competitor.
- Salesforce's enemy: spreadsheets and disconnected tools (not Siebel)
- Slack's enemy: email overload (not HipChat)
- Your enemy: ___________
**Step 3: Create the category name.**
It should be obvious in hindsight, not predictable in advance. Test it:
- Does it describe the problem, not the solution?
- Is it 2-3 words?
- Could a journalist use it without quoting you?
**Step 4: Missionary selling, not mercenary selling.**
Category kings educate the market before they sell to it. Content, thought leadership, community, and free tools all matter here — not as marketing tactics but as category creation.
**Step 5: Be the reference customer.**
Get the logos that define the category. The companies others look to. When others adopt, they don't want "a tool" — they want "what [Reference Customer] uses."
---
## 2. Competitive Moats
A moat is a structural advantage that compounds over time. Features are not moats. Pricing is not a moat. A moat is why, even if a competitor perfectly copies your product today, you still win.
### Moat Type 1: Network Effects
The product becomes more valuable as more users join. Two subtypes:
**Direct network effects:** Each user makes the product better for all other users (WhatsApp, Slack).
**Indirect network effects:** Each user on one side makes the product better for the other side (Uber drivers + riders, App Store developers + users).
**Data network effects:** More users → more data → better product → more users.
#### Network Effect Diagnostic
```
Question 1: Does adding user N make the product better for user N-1?
No → You don't have direct network effects
Yes → Map exactly how and how much
Question 2: Does adding user N make the product better for users on the OTHER side?
No → You don't have indirect network effects
Yes → Identify which side is the constraint (supply or demand)
Question 3: Does using the product generate data that improves the product?
No → You don't have data network effects
Yes → What is the data flywheel? Where does it compound?
```
**Building network effects intentionally:**
- Most products accidentally have weak network effects
- Design for network effects from Day 1: sharing, notifications, collaboration, integrations
- Measure network effect strength: "What % of new users were referred by existing users?"
### Moat Type 2: Switching Costs
The cost — time, money, risk — of leaving your product. The highest switching costs are:
| Switching Cost Type | Example | CPO Action |
|--------------------|---------|-----------|
| **Data lock-in** | Years of history, reports, trained models | Make data the experience, not just the storage |
| **Workflow integration** | 23 integrations, custom automations | Every integration is a switching cost. Build them. |
| **Team adoption** | Entire team trained on your tool | Multi-seat training investments pay switching cost dividends |
| **Contractual** | Annual contracts, SLAs | Long contracts are not a moat — customers resent them |
| **Process embedding** | Your product IS their process | Aim here. This is the deepest moat. |
**Warning:** Switching costs from data lock-in without value lock-in breed resentment, not loyalty. Customers who stay because they're trapped will leave the moment a migration tool appears.
### Moat Type 3: Data Advantages
Having data others can't easily get. Three subtypes:
**Proprietary data:** Data only you have access to (exclusive partnerships, sensor networks, unique user behavior at scale).
**Data scale:** Same type of data but at 10x the volume of competitors. Scale compounds model accuracy.
**Data variety:** Unique combination of data types. Not just usage data — usage + outcome data + external context.
**Testing your data moat:**
```
1. What data do we have that competitors don't?
2. At what volume does our data create a meaningfully better product?
3. Are we at that volume? If not, when?
4. Could a competitor buy or partner their way to equivalent data?
5. Is our data improving the product automatically, or only when we analyze it manually?
```
### Moat Type 4: Economies of Scale
Unit economics improve as you scale. Infrastructure costs drop per unit. Brand recognition lowers CAC. Negotiating power increases.
This is a real moat but the weakest one for product strategy — it doesn't keep faster-moving competitors from attacking while you're small.
### Moat Scorecard
Score each moat type 0-3 for your current product:
```
0 = Not present
1 = Weak / easily replicated
2 = Meaningful / takes 12-18 months to replicate
3 = Strong / structural advantage
Network effects (direct): __/3
Network effects (indirect): __/3
Network effects (data): __/3
Switching costs (data): __/3
Switching costs (workflow): __/3
Switching costs (team): __/3
Data advantages (exclusive): __/3
Data advantages (scale): __/3
Economies of scale: __/3
Total: __/27
< 9: No meaningful moat. Compete on execution speed.
9-15: Early moat. Identify and reinforce 1-2 strongest types.
16-21: Real moat. Invest to compound it.
> 21: Strong moat. Defend and expand.
```
---
## 3. Product Positioning
Positioning is not messaging. Positioning is the choice of: *Who is this for, what does it replace, and on what dimension do we win?*
### The Positioning Canvas (after April Dunford)
```
1. Competitive Alternatives
What would customers do if your product didn't exist?
(This is your real competition, not just your vendor category)
2. Unique Attributes
What capabilities do you have that alternatives lack?
(Features, but described neutrally, not as marketing)
3. Value (Outcomes)
What does each unique attribute enable for customers?
(Bridge from feature → outcome, not feature → feature)
4. Customer Who Cares
Who values those outcomes enough to pay for them?
(The customer segment for whom this value is highest)
5. Market Category
Where does the customer put you when comparing options?
(Frame the category to win, not to be fair)
6. Relevant Trends
What's changing in the world that makes this more valuable now?
(Why this moment? Urgency enabler.)
```
### Positioning Against Three Competitors
**Positioning vs. direct competitor:**
Identify one dimension where you structurally win. "Better" is not a position.
- Win on depth: more powerful in one scenario
- Win on simplicity: fewer decisions, fewer steps
- Win on integration: works with what they already use
- Win on price/value: same outcome, lower cost or risk
**Positioning vs. indirect alternative:**
The customer's current solution (spreadsheet, manual process, point solution).
- Make switching cost obvious (what are they giving up per week?)
- Make the switch simple (migration, onboarding, no data loss)
- Find the "aha moment" fast (value before they revert)
**Positioning vs. doing nothing:**
The hardest competitor. Status quo has zero switching cost.
- Quantify the cost of inaction (time, risk, revenue, competitive risk)
- Find the trigger event that makes inaction intolerable
- Show the risk is higher than the switch cost
### Positioning Failure Modes
| Failure | Description | Fix |
|---------|-------------|-----|
| **For everyone** | No segment. "Any company that needs X." | Name the best-fit customer. |
| **Feature positioning** | "The only tool with [feature X]" | Features are table stakes. Lead with outcome. |
| **Vague differentiation** | "Easier, faster, better" | Measurable, specific, or don't say it. |
| **Category misfit** | In a category where you can't win | Either own the category or name a new one |
| **Lagging positioning** | Positioned for who you were, not who you are | Reposition every 18-24 months or after major product change |
---
## 4. Portfolio Management
### Applying BCG Matrix to Product Lines
BCG matrix was designed for business units. Applied to product lines:
**Inputs:**
- Market growth rate (industry growth, not your growth)
- Relative market share (your share vs. largest competitor)
- Revenue contribution (absolute)
- Investment level (engineering + sales + marketing per product)
**Calculation:**
```
Market share ratio = Your market share / Largest competitor's market share
Growth rate = Market CAGR (next 3 years estimate)
Stars: share ratio > 1.0, growth > 10%
Cash Cows: share ratio > 1.0, growth < 10%
Question Marks: share ratio < 1.0, growth > 10%
Dogs: share ratio < 1.0, growth < 10%
```
### Portfolio Allocation Rules
**Star products:**
- Invest at or above market growth rate
- Goal: maintain share leadership as market grows
- Don't extract cash — reinvest
- Metrics: market share trend, NPS, retention, feature velocity
**Cash Cow products:**
- Minimum investment to maintain market position
- Goal: maximize free cash flow
- Resist the urge to innovate — incremental improvements only
- Metrics: gross margin, churn rate, support cost per customer
**Question Mark products:**
- Binary decision: invest to win or exit
- "Maintain" is not a strategy for question marks — you lose share every quarter you're neutral
- Set a deadline (2 quarters) and a threshold for investment decision
- Metrics: share gain rate, customer acquisition efficiency
**Dog products:**
- Decision: sell, sunset, or bundle
- Never "fix" a dog with more investment
- Timeline to sunset: 6-12 months, migration plan for existing customers
- Metrics: customer migration rate, revenue retained
### Portfolio Review Template
Run quarterly. One slide per product.
```
Product: [Name]
Current Quadrant: [Star/Cash Cow/Question Mark/Dog]
Revenue this quarter: $___
Revenue growth QoQ: ___%
Market share estimate: ___%
Investment level (% of eng capacity): ___%
Investment posture: [Invest / Maintain / Kill]
Key metric: [Name] → [Current value] → [QoQ trend]
Top risk: [One thing that could change this assessment]
Decision required: [Yes/No] | [What decision?]
```
### The Honest Portfolio Conversation
Questions CPOs avoid but boards ask:
- "Which product would we kill if we had to? What's stopping us?"
- "Are we funding dogs because the team is attached or because there's a real plan?"
- "What would our margins look like if we stopped investing in the bottom 2 products?"
- "What's the dependency between our products? Are we a platform or a bundle of unrelated tools?"

## 5. Board-Level Product Reporting
### What Good Looks Like
Board product updates fail in three ways:
1. Too much roadmap detail (feature list masquerading as strategy)
2. No trend context (showing a number without showing if it's getting better or worse)
3. No risks (all good news = no credibility)
### The 5-Slide Board Product Update
**Slide 1: North Star Metric**
```
Title: Product Health — [Quarter]
[Chart: North star metric over last 12 months, quarterly cohorts]
This quarter: [Value] | Prior quarter: [Value] | YoY: [Value]
Target: [Value] | Status: On track / At risk / Behind
Drivers (2-3 bullets):
• What's driving improvement: ___
• What's dragging: ___
• What we're doing about the drag: ___
```
**Slide 2: Retention and PMF**
```
Title: Product-Market Fit Evidence
[Chart: D30 retention by cohort, last 6 cohorts]
[Callout: Sean Ellis score = XX% (target: > 40%)]
PMF status: Achieved / Approaching / Not yet
Best segment: [Describe — where retention is strongest]
Weakest segment: [Describe — and what we're doing about it]
```
**Slide 3: Portfolio Status**
```
Title: Portfolio — Invest / Maintain / Kill
| Product | Quadrant | Revenue | Growth | Posture | Risk |
|---------|---------|---------|--------|---------|------|
| [A] | Star | $___ | +XX% | Invest | ___ |
| [B] | Cash Cow| $___ | +X% | Maintain| ___ |
| [C] | Dog | $___ | -X% | Kill Q3 | ___ |
Changes since last quarter: ___
Decisions needed from board: ___
```
**Slide 4: Strategic Bets**
```
Title: Bets This Half — [H1/H2]
Bet 1: [Name]
Hypothesis: If we [do X], [segment Y] will [do Z]
Evidence so far: [Data]
Confidence: [Low / Medium / High]
Decision point: [When do we know?] [What will we measure?]
Bet 2: [Name]
[Same structure]
```
**Slide 5: Top Risks**
```
Title: Product Risks — [Quarter]
Risk 1: [Name]
What it is: ___
Probability: [Low/Med/High]
Impact if realized: ___
Mitigation: ___
Risk 2: [Name]
[Same structure]
Risk 3: [Name]
[Same structure]
```
### Delivering in the Board Meeting
- Never read the slide
- Lead with the conclusion, not the data
- Prepare for "what if that assumption is wrong?" for every bet
- When something underperformed: say it, own it, explain what changed
- Never present a number you can't explain 3 levels deep
**Example of bad delivery:**
"Our north star is up 15% QoQ, which is great. We're tracking well."
**Example of good delivery:**
"North star is up 15% — ahead of plan. The majority of that is from the enterprise cohort activated in October, driven by the workflow automation feature we shipped in September. The consumer segment is flat, which is a concern. We're running three experiments this quarter to diagnose whether that's an acquisition problem or an activation problem — I'll have an answer for next quarter."

# Workflow Builder
Author runnable workflow scripts for Claude Code's Workflow tool: deterministic multi-agent orchestration files (`.js`) that fan work out to fresh-context sub-agents under plain JavaScript control flow. Only leaf `agent()` calls spend tokens, so the main session stays clean and the whole run is resumable.
## ALWAYS start every session with intake (non-negotiable)
Before proposing or writing any workflow, run the intake. Do not skip to code.
1. **Ask what kind of workflow they want.** Use this opening question set:
- What repeatable, multi-step task do you want to automate?
- What is the one unit of work a single sub-agent does once?
- How many units — a known list, or discovered by looping?
- Do later steps need *all* prior results at once, or can each item flow on its own?
- Does any step need structured data back (a verdict, a list, scores)?
- Roughly how many tokens / how deep should it go?
2. **If the user is vague, do NOT stall.** Run the recommendation engine to turn whatever you have into 1-2 concrete proposals, then present them *with the reasoning*:
```bash
python scripts/workflow_intake.py --task "their description" \
--units unknown --stages unknown --needs-all unknown --structured unknown
```
The engine returns a recommended topology (fan-out / pipeline / loop / barrier / judge-panel), model picks, a budget guard, and a one-line rationale per choice. Present those as "Here's what I'd build and why" — never ask the user to re-answer questions they already half-answered.
3. **Confirm the shape with the user** (topology + phases + parallel-vs-pipeline) before writing the file. This is the only approval gate.
See [references/decision_and_intake_guide.md](references/decision_and_intake_guide.md) for the full question framework, the vague-input playbook, and worked recommendation examples.
## Decide if a workflow is even the right tool
| Scenario | Use |
|----------|-----|
| Single sub-agent, one task | plain Agent tool |
| Reusable procedure, Claude picks steps dynamically | a Skill |
| Many sub-agents in a fixed topology, deterministic + resumable | **Workflow** ✓ |
Workflows earn their cost when work is parallel or multi-stage, must be reproducible, long enough to fail halfway (so resume matters), or benefits from isolating each step in its own context window. For one-off tasks, just use Claude directly.
## Build → validate → run loop
1. **Scaffold** a starter from the confirmed topology:
```bash
python scripts/scaffold_workflow.py --topology pipeline --name pr-triage \
--description "Triage open PRs" > .claude/workflows/pr-triage.js
```
2. **Edit** the file: `meta` block first (pure literal, first statement), then the async body using the injected globals — `agent()`, `pipeline()`, `parallel()`, `phase()`, `log()`, `budget`, `args`, `workflow()`. Full surface in [references/api_reference.md](references/api_reference.md); copy-paste shapes in [references/orchestration_patterns.md](references/orchestration_patterns.md).
3. **Validate** before running — catches the parser-fatal mistakes:
```bash
python scripts/validate_workflow.py .claude/workflows/pr-triage.js
```
4. **Run** it: enable the feature with `export CLAUDE_CODE_WORKFLOWS=1`, save the file under `.claude/workflows/`, then use `/workflows` to launch and watch it live. Press **P** to pause/resume, **X** to skip a sub-agent. Failed agents retry automatically.
## Hard rules (validator enforces these)
- `meta` is a **pure literal** and the **first statement** — no variables, spreads, template strings, or function calls inside it.
- **No non-determinism:** `Date.now()`, `Math.random()`, argless `new Date()` break resume — pass timestamps via `args`.
- **No filesystem / Node APIs** (`require`, `fs`, `process`, network) in the orchestrator — that work belongs *inside* `agent()` prompts.
- `parallel()` takes **thunks** (`() => agent(...)`), not bare promises. Default to `pipeline()` unless a stage needs the whole prior result set.
- **Guard every open-ended loop** with a counter or `budget.remaining()` check — unguarded loops hit the 1000-agent cap.
- Filter skipped/failed agents: `results.filter(Boolean)`.
## Tooling
- `scripts/workflow_intake.py` — intake recommendation engine (topology + model + budget + rationale from vague input).
- `scripts/validate_workflow.py` — stdlib linter for the rules above; PASS / WARN / FAIL with line numbers.
- `scripts/scaffold_workflow.py` — generate a starter `.js` for any topology.
- `assets/templates/` — fan-out, pipeline, loop-until-budget starters. `assets/examples/` — a complete runnable workflow.
All scripts run with `--sample` (no args) and `--help`.

# workflow-builder (skill)
Intake-first authoring of deterministic multi-agent **workflow `.js` files** for Claude Code's Workflow tool (`CLAUDE_CODE_WORKFLOWS=1`, `/workflows`). See the plugin root [README](../../README.md) for the full overview and attribution.
## Tools (`scripts/`)
| Tool | Purpose |
|---|---|
| `workflow_intake.py` | Classify a (vague) task → recommended topology + runner-up + per-stage model plan + budget guard + rationale. |
| `validate_workflow.py` | Lint a workflow `.js`: pure-literal `meta`, no non-determinism, no Node/FS APIs, `parallel()` thunks, guarded loops, `filter(Boolean)`, size cap. PASS / WARN / FAIL with line numbers. |
| `scaffold_workflow.py` | Emit a runnable starter for any of 5 topologies (fan-out, pipeline, barrier, loop, judge-panel). |
All three run with `--sample` (no args) and `--help`.
## Quick start
```bash
python scripts/workflow_intake.py --task "review my open PRs for bugs"
python scripts/scaffold_workflow.py --topology pipeline --name pr-triage \
--description "Triage open PRs" > /tmp/pr-triage.js
python scripts/validate_workflow.py /tmp/pr-triage.js
```
## Layout
- `references/` — API surface, orchestration patterns, decision + intake guide.
- `assets/templates/` — fan-out / pipeline / loop-until-budget starters.
- `assets/examples/` — a complete PR-triage workflow.
- `expected_outputs/` — captured deterministic tool outputs used as regression fixtures.

# Workflow API Reference
Complete surface for Claude Code's Workflow tool: every global, option, cap, and constant a workflow `.js` file can rely on. A workflow file has exactly two parts in order — a `meta` literal, then an async body that uses the injected globals below.
## 1. `meta` declaration
`meta` must be the **first statement** and a **pure object literal** — no variables, spreads, template strings, or function calls inside it. Reserved keys (`__proto__`, `constructor`, `prototype`) are rejected by the parser.
```js
export const meta = {
name: 'workflow-name', // required, non-empty string
description: 'One-line summary', // required

}
```
## 2. Injected globals
| Global | Signature | Returns |
|--------|-----------|---------|
| `agent()` | `agent(prompt, opts?) → Promise<string\|object>` | Text, or a validated object when `schema` is set |
| `pipeline()` | `pipeline(items, ...stages) → Promise<any[]>` | Streamed per-item results (no barrier between stages) |
| `parallel()` | `parallel(thunks) → Promise<any[]>` | Concurrent results (barrier — waits for all) |
| `phase()` | `phase(title) → void` | Groups subsequent agents under a heading |
| `log()` | `log(message) → void` | Narrator output to the workflow log |
| `console` | `.log()`, `.error()`, … | Routed into the workflow log |
| `workflow()` | `workflow(nameOrRef, args?) → Promise<any>` | Result of a nested workflow (one level deep max) |
| `args` | any | The input passed to the workflow, unchanged |
| `budget` | `{ total, spent(), remaining() }` | Token tracking |
## 3. `agent()` options
```js
agent(prompt, {
label: 'string', // display name (~60 char default)
phase: 'phase-name', // progress-group assignment
schema: { type: 'object' },// JSON Schema — validates + structures the return
model: 'haiku', // 'haiku' | 'sonnet' | 'opus' | 'inherit' | full-model-id
isolation: 'worktree', // run in a fresh git worktree (~200-500 ms + disk)
agentType: 'agent-type', // custom sub-agent type
stallMs: 180000 // per-agent stall timeout override (ms)
})
```
**Model resolution:** `haiku`/`sonnet`/`opus` resolve to the current default of that family; `inherit` (the default) uses the session main-loop model; a full model ID passes through unchanged. Pick lighter models (Haiku) for classification/extraction and heavier ones (Opus) for synthesis or hard reasoning.
**Resume cache key** includes `schema`, `model`, `isolation`, and `agentType` — changing any of these re-runs the agent on resume. `label` and `phase` do **not** invalidate the cache.
## 4. `pipeline()` vs `parallel()`
**`pipeline(items, stage1, stage2, …)`** — each item flows through every stage independently; there is no barrier between stages, so stage 2 starts for an item the moment stage 1 finishes for *that* item. Stage callbacks receive `(prevResult, originalItem, index)`. Wall-clock time ≈ the slowest single item's full chain, not the sum of slowest-per-stage. **Default choice for multi-stage work.**
**`parallel(thunks)`** — runs an array of `() => Promise` thunks concurrently and waits for all (a barrier). Use only when the next step genuinely needs the entire prior result set — dedup, merge, or a count-based exit. Requires thunks, not bare promises: `parallel([() => agent(a), () => agent(b)])`.
## 5. `budget` object
```js
budget.total // user-set target, or null if none
budget.spent() // output tokens spent this turn
budget.remaining() // max(0, total - spent()), or Infinity when total is null
```
Throws `WorkflowBudgetExceededError` once `spent()` reaches `total`. Use `budget.remaining()` as a loop guard for depth-scaling workflows.
## 6. Caps & limits
| Limit | Value | Behavior on breach |
|-------|-------|--------------------|
| Agent calls per run | 1000 | throws `WorkflowAgentCapError` |
| Concurrent agents | `min(16, max(2, cores − 2))` | excess calls queue |
| Script size | 524,288 bytes | rejected before parsing |
| Per-agent stall | 180,000 ms (3 min) | aborted, retried up to 5× |
| Sync timeout | 30,000 ms | catches infinite synchronous loops |
## 7. Sandbox restrictions
**Banned (non-reproducible — break resume):**
- `Math.random()` → vary the agent prompt by index instead.
- `Date.now()` → pass timestamps in via `args`.
- argless `new Date()` → use `new Date(specificValue)`.
**No access** to filesystem, Node APIs (`require`, `fs`, `process`), or network from the orchestrator. Any work needing those must happen *inside* an `agent()` call (the sub-agent has full tool access).
## 8. Execution & resume
1. The script is persisted to the session directory.
2. A background task launches and returns a run ID (`wf_…`).
3. A journal records each `agent()` call keyed by a hash of `(prompt, opts)`.
4. Resume via `Workflow({ scriptPath, resumeFromRunId })` — cached calls return instantly; only changed or new calls re-run. Resume works **same-session only**; edit the saved file and re-invoke with `scriptPath`.
## 9. Enabling the feature
The Workflow tool is gated behind an environment variable and off by default:
```bash
export CLAUDE_CODE_WORKFLOWS=1
```
Save workflow files under `.claude/workflows/` in the project, then browse, launch, and monitor them with the `/workflows` slash command. **P** pauses/resumes a run; **X** skips a sub-agent.

# Decision & Intake Guide
The workflow-builder skill opens **every** session with intake. This file is the full framework behind that gate: the questions to ask, how to handle vague answers, and worked examples of turning a fuzzy request into a concrete proposal.
## Why intake comes first
A workflow's whole value is deterministic, resumable, fixed-topology orchestration. The topology is a *design decision* that must be made before any code — choosing pipeline vs. parallel, known-list vs. loop, or whether a step needs structured output changes the entire file. Asking first is cheaper than rewriting. It also catches the most common mistake: building a workflow when a single agent or a skill would do.
## The opening question set
Ask these at the start of a workflow-creation session. Lead with #1; the rest sharpen the shape.
1. **What repeatable, multi-step task do you want to automate?** (the goal)
2. **What is the one unit of work** a single sub-agent does once? (e.g., "review one file", "research one question")
3. **How many units** — a known list, or discovered by looping until some condition?
4. **Do later steps need *all* prior results at once** (dedup/merge/count), or can each item flow independently?
5. **Does any step need structured data back** — a verdict, a list, scores?
6. **How deep / how many tokens** should this go? (sets the budget guard)
Map answers → topology:
| Signal | Topology |
|--------|----------|
| Independent units, known list, combine at end | **fan-out → synthesize** (`parallel` + final `agent`) |
| Ordered stages, each item advances on its own | **pipeline** |
| A stage needs the whole prior set (dedup/merge/early-exit) | **barrier** (`parallel`, then process) |
| Unknown count, stop on goal / budget / dryness | **loop** (guarded) |
| Wide solution space, want best-of-N | **judge panel** |
| A wrong result is costly | add **skeptic-vote** verification on that finding |
## The vague-input playbook
When the user gives a one-liner ("I want to review my PRs") or skips the topology questions, **do not interrogate them in a loop.** Infer, propose, and explain. Run:
```bash
python scripts/workflow_intake.py --task "review my open PRs for bugs" \
--units unknown --stages unknown --needs-all unknown --structured unknown
```
The engine classifies the task by keywords, fills unknowns with the safest default, and returns:
- a **recommended topology** (and a runner-up if it's close),
- **model picks** per stage (Haiku for triage/extraction, Opus for synthesis),
- a **budget guard** suggestion,
- a **one-line rationale for every choice** so you can present "here's what I'd build and why."
Then say, in your own words: *"You were light on detail, so here's the approach I'd recommend and why — tell me what to change."* Present the topology, the phases, and the parallel-vs-pipeline call. Only after the user reacts do you scaffold.
### Defaults the engine applies to unknowns (and why)
| Unknown | Default | Why |
|---------|---------|-----|
| unit count | loop with a hard cap | safest when count is undiscovered; cap prevents the 1000-agent ceiling |
| stages | single stage unless the task names a verb chain | most fuzzy asks are one-pass fan-outs, not pipelines |
| needs-all-results | no (prefer pipeline) | pipeline is strictly faster and the default per the API; only add a barrier on evidence |
| structured output | yes, lightweight schema | a small schema makes downstream stages reliable at near-zero cost |
| budget | guard at `remaining() > 50k` | keeps runaway loops from draining the turn |
## Worked examples
**"Review my PRs."**
Unit = one PR (a known list, gathered inside the first agent). Each PR is reviewed once, independently. Wrong result costly = yes (a false positive wastes review time, a miss ships a bug). → **fan-out** (one review per PR, Haiku, structured findings) → **skeptic-vote** on each high-severity finding (Sonnet) → a final synthesis. If you want a distinct *verify* pass after review, split it into a two-stage **pipeline** instead. Rationale handed to the user: fan-out because PRs are independent; skeptic-vote because acting on a false positive is costly.
**"Summarize a folder of documents."**
Unit = one document. Count = known list (the folder contents, gathered inside the first agent). Combine at end = yes. → **fan-out** (Haiku per doc, structured summary) → **synthesize** (Opus, one report). No loop, no barrier mid-stream. Rationale: documents are independent, so parallel; one final synthesis because the user wants a single summary.
**"Find security issues until you run out of budget."**
Unit = one issue. Count = unknown, budget-bounded. → **loop-until-budget** guarded by `budget.remaining() > 50_000`, structured issue schema, dedup by id. Rationale: depth scales to the token target; the guard is mandatory or it hits the agent cap.
## When to walk away from a workflow
If intake reveals a single agent and one task, say so and recommend the plain Agent tool. If it's a procedure where Claude should pick steps dynamically rather than a fixed topology, recommend a Skill instead. Not every multi-step task earns a workflow — only deterministic, resumable, fan-out/pipeline/loop shapes do.

# Orchestration Patterns
Copy-paste shapes for the common multi-agent topologies. Pick by answering the topology questions in [decision_and_intake_guide.md](decision_and_intake_guide.md), then adapt one of these.
## 1. Fan-out then synthesize
**When:** a known list of independent items, one pass each, and you need one combined answer at the end.
```js
const findings = await parallel(
questions.map((q, i) => () =>
agent(`Research and report verified facts:\n\nq`,
{ label: `qi + 1`, schema: RESEARCH_SCHEMA }))
)
const report = await agent(
`Synthesize these findings into one report:\nJSON.stringify(findings.filter(Boolean))`,
{ model: 'opus' }
)
```
## 2. Pipeline: stage then stage (no barrier)
**When:** items progress through ordered stages and each item should advance the instant it's ready, not wait for siblings.
```js
const results = await pipeline(
DIMENSIONS,
d => agent(d.prompt, { label: `review:d.key`, phase: 'Review', schema: FINDINGS_SCHEMA }),
review => parallel((review?.findings ?? []).map(f => () =>
agent(`Adversarially verify: f.title`, { schema: VERDICT_SCHEMA })))
)
```
## 3. Barrier when you must dedup / merge first
**When:** the next stage needs the *entire* previous result set in hand — to dedup, merge, or early-exit on a count.
```js
const all = await parallel(DIMENSIONS.map(d => () => agent(d.prompt, { schema: FINDINGS_SCHEMA })))
const deduped = dedupeByFileAndLine(all.filter(Boolean).flatMap(r => r.findings))
const summary = await agent(`Summarize deduped.length unique findings:\nJSON.stringify(deduped)`)
```
## 4. Loop until target count
**When:** discovery with a fixed goal ("find 10 bugs"). Always bound it.
```js
const bugs = []
while (bugs.length < 10 && bugs.length < 100 /* hard cap guard */) {
const r = await agent(
`Find bugs NOT already listed:\nJSON.stringify(bugs)`,
{ schema: BUGS_SCHEMA }
)
if (!r?.bugs?.length) break
bugs.push(...r.bugs)
}
```
## 5. Loop until budget runs low
**When:** depth should scale to the user's token target. The `budget` guard is essential.
```js
const issues = []
while (budget.total && budget.remaining() > 50_000) {
const r = await agent('Find one more issue not yet reported...', { schema: ISSUE_SCHEMA })
if (!r?.issues?.length) break
issues.push(...r.issues)
}
```
## 6. Adversarial verification (skeptic vote)
**When:** a finding will be acted on and a plausible-but-wrong one is costly. Findings survive on majority vote.
```js
const votes = await parallel(Array.from({ length: 3 }, (_, i) => () =>
agent(`Try hard to REFUTE this claim, return { refuted: boolean }:\nclaim`,
{ label: `skeptic:i + 1`, schema: VERDICT_SCHEMA })))
const survives = votes.filter(v => v && !v.refuted).length >= 2
```
## 7. Judge panel
**When:** a wide solution space benefits from several independent attempts, scored and synthesized.
```js
const drafts = await parallel(ANGLES.map(a => () =>
agent(`Produce a plan. Take a strictly a approach.`)))
const scored = await parallel(drafts.map((d, i) => () =>
agent(`Score this plan 1-10 with reasons:\nd`, { label: `judge:i + 1`, schema: SCORE_SCHEMA })))
const winner = drafts[scored.indexOf(scored.reduce((a, b) => (a?.score ?? 0) >= (b?.score ?? 0) ? a : b))]
const final = await agent(`Refine the winning plan:\nwinner`, { model: 'opus' })
```
## 8. Loop until dry
**When:** unknown-size discovery that stops after K consecutive rounds with no new findings.
```js
const found = []
const seen = new Set()
let dryRounds = 0
while (dryRounds < 2 && found.length < 100) {
const r = await agent(`Find items not in:\nJSON.stringify([...seen])`, { schema: ITEMS_SCHEMA })
const fresh = (r?.items ?? []).filter(x => !seen.has(x.id))
fresh.forEach(x => seen.add(x.id))
found.push(...fresh)
dryRounds = fresh.length === 0 ? dryRounds + 1 : 0
}
```
## 9. Nested workflow
**When:** a self-contained sub-job lives inside a larger one (one level deep maximum).
```js
const research = await workflow('research-fanout', ['question one', 'question two'])
```
## Schema declarations
Schemas are plain JSON Schema objects defined as top-level `const`s and passed via `{ schema }`:
```js
const FINDINGS_SCHEMA = {
type: 'object',
properties: {
findings: {
type: 'array',
items: {
type: 'object',
properties: {
title: { type: 'string' },
severity: { type: 'string', enum: ['low', 'medium', 'high'] },
file: { type: 'string' }
},
required: ['title', 'severity']
}
}
},
required: ['findings']
}
```
Between stages, stringify structured data into the next prompt (`JSON.stringify(...)`); the schema only shapes what comes *back* from a single `agent()` call.

# Writing Skills
> Derived from [Matt Pocock's write-a-skill](https://github.com/mattpocock/skills/tree/main/skills/productivity/write-a-skill) (MIT). Matt's voice and 3-phase workflow preserved verbatim. Additions: validation tools + references + cs-* wrapper (see *Tooling + Companions* below).
## Process
1. **Gather requirements** - ask user about:
- What task/domain does the skill cover?
- What specific use cases should it handle?
- Does it need executable scripts or just instructions?
- Any reference materials to include?
2. **Draft the skill** - create:
- SKILL.md with concise instructions
- Additional reference files if content exceeds 500 lines
- Utility scripts if deterministic operations needed
3. **Review with user** - present draft and ask:
- Does this cover your use cases?
- Anything missing or unclear?
- Should any section be more/less detailed?
## Skill Structure
```
skill-name/
├── SKILL.md # Main instructions (required)
├── REFERENCE.md # Detailed docs (if needed)
├── EXAMPLES.md # Usage examples (if needed)
└── scripts/ # Utility scripts (if needed)
└── helper.js
```
## SKILL.md Template
```md
---
name: skill-name
description: Brief description of capability. Use when [specific triggers].
---
# Skill Name
## Quick start
[Minimal working example]
## Workflows
[Step-by-step processes with checklists for complex tasks]
## Advanced features
[Link to separate files: See [REFERENCE.md](REFERENCE.md)]
```
## Description Requirements
The description is **the only thing your agent sees** when deciding which skill to load. It's surfaced in the system prompt alongside all other installed skills. Your agent reads these descriptions and picks the relevant skill based on the user's request.
**Goal**: Give your agent just enough info to know:
1. What capability this skill provides
2. When/why to trigger it (specific keywords, contexts, file types)
**Format**:
- Max 1024 chars
- Write in third person
- First sentence: what it does
- Second sentence: "Use when [specific triggers]"
**Good example**:
```
Extract text and tables from PDF files, fill forms, merge documents. Use when working with PDF files or when user mentions PDFs, forms, or document extraction.
```
**Bad example**:
```
Helps with documents.
```
The bad example gives your agent no way to distinguish this from other document skills.
## When to Add Scripts
Add utility scripts when:
- Operation is deterministic (validation, formatting)
- Same code would be generated repeatedly
- Errors need explicit handling
Scripts save tokens and improve reliability vs generated code.
## When to Split Files
Split into separate files when:
- SKILL.md exceeds 100 lines
- Content has distinct domains (finance vs sales schemas)
- Advanced features are rarely needed
## Review Checklist
After drafting, verify:
- [ ] Description includes triggers ("Use when...")
- [ ] SKILL.md under 100 lines
- [ ] No time-sensitive info
- [ ] Consistent terminology
- [ ] Concrete examples included
- [ ] References one level deep
## Tooling + Companions
Validation tools + cs-* wrapper sit alongside this skill. Run all 6 review-checklist items programmatically:
```
python scripts/skill_review_checklist_runner.py path/to/skill-folder
```
See [references/companion_tooling.md](references/companion_tooling.md) for the tool catalogue, cs-skill-author persona agent, and `/cs:write-a-skill` slash command.

# Companion Tooling
Validation tools + cs-* wrapper layered on top of Matt's write-a-skill. Use these when authoring a new skill in this repo.
## Validation Tools (stdlib Python)
| Tool | Purpose | Run before |
|---|---|---|

## cs-skill-author Persona Agent
Lives at `../agents/cs-skill-author.md`. Voice: forcing-question interrogator. Surfaces Matt's skill-authoring workflow as an interrogation before any new skill commit.
**Opening question:** "What capability does this skill provide, and what's the trigger phrase that distinguishes it from existing skills?"
**Six forcing questions** (matches the review checklist):
1. What's the description? Is it ≤1024 chars + third person + has "Use when ..."?
2. Is SKILL.md under 100 lines? If not, where will the split land (REFERENCE.md / EXAMPLES.md / references/)?
3. Are there time-sensitive claims (dates, "as of YYYY")?
4. Is terminology consistent — same word for the same concept throughout?
5. Concrete examples — at least 1 code block, ideally good/bad contrast?
6. References one level deep, no circular refs?
## `/cs:write-a-skill` Slash Command
Lives at `../commands/cs-write-a-skill.md`. Three-step flow:
1. Run `cs-skill-author` interrogation (6 questions)
2. Draft skill files per Matt's structure pattern
3. Run all 3 validation tools; show verdict; fix until PASS
Use when: starting a new skill in this repo from scratch.
## Why Wrap Matt's Original
Matt's write-a-skill is a tight, principled, ~93-line skill — perfect as-is for individual authoring sessions. The wrapper layers add three things this repo benefits from at scale:
1. **Programmatic enforcement** of Matt's review checklist (the validation tools) — prevents human review-checklist drift across 100+ skills.
2. **Forcing-question interrogation** (the cs-skill-author persona) — adapts Matt's "review with user" phase to the cs-* persona pattern used elsewhere in this repo.
3. **Citation-backed references** — Matt links to his own materials; the wrapper adds 5+ authoritative external sources per reference (Anthropic skill docs + community precedent + research) for newcomers learning the pattern.
This is the [hybrid voice approach](../SKILL.md): Matt's words for the principles, our additions for the tooling.

# Description Design Patterns for Skills
This reference answers exactly one decision: **how do we write a skill description that an agent actually picks correctly when faced with a long skill list?**
Pair with `scripts/skill_description_validator.py` for automated enforcement.
## Matt Pocock's Foundational Rule
> "The description is **the only thing your agent sees** when deciding which skill to load."
>
> — Matt Pocock, write-a-skill
Implication: the description is not marketing copy. It's a routing signal for the agent. Every word competes with every other skill's description for activation attention.
## The Four Format Rules (per Matt)
1. **Max 1024 chars** — beyond this, agents lose the early sentences when condensing context
2. **Third person** — first-person ("I help with...") confuses agent self-identification; second-person ("You can...") confuses pronoun reference
3. **First sentence: what it does** — front-load the verb + object
4. **Second sentence: "Use when [specific triggers]"** — agent's most reliable activation cue
## Good vs Bad Examples (Matt's pattern, expanded)
**Good** (Matt's PDF example):
```
Extract text and tables from PDF files, fill forms, merge documents. Use when working with PDF files or when user mentions PDFs, forms, or document extraction.
```
**Why good:**
- Front-loaded verbs: Extract, fill, merge
- Concrete objects: text, tables, PDF files, forms
- Explicit trigger: "Use when working with PDF files"
- Specific keywords for matching: "PDFs", "forms", "document extraction"
**Bad** (Matt's):
```
Helps with documents.
```
**Why bad:**
- "Helps" is content-free
- "Documents" is generic — every doc skill has this
- No trigger
- No keyword variety
**Bad in different way** (over-specified):
```
This skill performs comprehensive PDF document processing including but not limited to extraction, manipulation, format conversion, content analysis, metadata management, and security operations on PDF files, with support for various PDF versions and embedded media types.
```
**Why bad:** verbose, no triggers, agent can't extract the key keywords from the wall of text.
## The Trigger Sentence Pattern
The "Use when" sentence is the highest-leverage part of the description. Patterns that work:
**Keyword triggers** (when user types specific words):
```
Use when user mentions PDFs, forms, or document extraction.
```
**File-type triggers** (when agent sees specific files):
```
Use when working with `.tsx` files or React component tests.
```
**Context triggers** (when agent is in a specific state):
```
Use when the user requests a code review of a pull request.
```
**Workflow triggers** (when agent is mid-workflow):
```
Use after running tests and before committing changes.
```
## Vocabulary Selection
The description's words must overlap with words users + agents naturally use for the task.
| Bad keyword | Better keyword | Why |
|---|---|---|
| "documents" | "PDF files" / "Word docs" | More specific = less collision |
| "improve" | "refactor" / "fix" / "optimize" | Specific verb = clearer routing |
| "various" | (delete; just list them) | Hedge language = no info |
| "modern" | (cite the actual tool/version) | Trend words age badly |
| "comprehensive" | (delete; just list capabilities) | Adjective inflation |
## Length Optimization
Below 1024 chars, shorter is usually better. Target: 100-300 chars for most skills.
Where complexity demands more chars, prioritize:
1. The verb-object pair (what it does) — never compress
2. The trigger phrase — never compress
3. Keyword variety (different ways users describe it) — expand here if space allows
4. Anti-keyword (what it does NOT do) — only if there's a frequently-confused sibling skill
## Anti-Patterns to Avoid
1. **First-person voice** — "I extract PDFs" — confuses agent self-reference
2. **Marketing language** — "fast, powerful, intuitive" — agent doesn't care, ignores adjectives
3. **Trigger-less descriptions** — every skill needs "Use when X"
4. **Multi-purpose dumping** — if your skill does 10 unrelated things, it's probably 10 skills
5. **Pronouns and hedges** — "you can also use this if you want to" — drop entirely
6. **Recursive descriptions** — "Use this skill when you need this skill" — adds nothing
7. **Implementation details** — "Built on Python + stdlib" — agent doesn't care; matters for README, not description
## Pre-Commit Discipline
Run before every skill PR:
```bash
python scripts/skill_description_validator.py path/to/SKILL.md
```
If validator returns FAIL, fix before merging. If WARN, justify and document the trade-off.
## When This Reference Doesn't Help
- **Naming the skill itself** — different concern; see naming-conventions guidance per-repo
- **Skill discovery in marketplaces** — different audience (humans browsing), different rules
- **System-prompt design for the agent that loads skills** — upstream concern

# Progressive Disclosure for Skill Files
This reference answers exactly one decision: **when should a SKILL.md be split into reference files, and how do we keep the disclosure ladder shallow + scannable?**
Pair with `scripts/skill_structure_validator.py` for automated enforcement of the 100-line ceiling + one-level-deep rule.
## What "Progressive Disclosure" Means in Skill Files
Progressive disclosure = present the minimum needed to act, with paths to deeper detail when needed. For agent skills:
- **SKILL.md** = the description + minimum workflow the agent needs to invoke the skill
- **REFERENCE.md / EXAMPLES.md / references/*.md** = deep detail invoked only when the SKILL.md workflow points there
- **scripts/** = deterministic operations (no LLM token cost; no inconsistency risk)
The goal: agent reads SKILL.md and either has enough to act, or has a clear link to the specific reference file that resolves its question. No deeper than that.
## Matt Pocock's Original Rule (the 100-Line Ceiling)
> "Split into separate files when:
> - SKILL.md exceeds 100 lines
> - Content has distinct domains (finance vs sales schemas)
> - Advanced features are rarely needed"
>
> — Matt Pocock, write-a-skill
The 100-line ceiling is empirical: agents reading >100 lines of SKILL.md tend to over-condition on tangential detail; below 100 lines, the agent reads the entire skill and routes correctly to references or scripts when needed.
## When the Ceiling Is Right vs Wrong
| Situation | 100-line ceiling appropriate? |
|---|---|
| Single-action skill (e.g., format-json) | Yes — fits comfortably under 50 lines |
| Mid-complexity skill with 2-3 workflows | Yes — 70-100 lines |
| Skill with 4+ workflows + extensive examples | No — split workflows into separate reference files |
| Domain-spanning skill (multi-framework like compliance-os) | No — split per-framework into separate references |
| Skill that wraps another (derived/extension) | Special case — wrapper additions push past 100; treat as warning, not failure |
## The One-Level-Deep Rule
> "References one level deep" — Matt Pocock review checklist
Why: agent loading a reference file should resolve its question without further indirection. If `REFERENCE.md` says "see `references/foo.md` for more on bar," then bar's content is the leaf — it shouldn't say "see references/foo/bar/baz.md."
Operational consequence: keep `references/` flat. No nested subfolders.
## Anti-Patterns to Avoid
1. **SKILL.md as a complete manual** — 300-line SKILL.md with every workflow inline. Agent over-conditions; token cost on every invocation.
2. **Reference soup** — 20 reference files at one level. Hard to scan; agent can't tell which to load.
3. **Circular references** — `A.md` → `B.md` → `A.md`. Agent loops or fails.
4. **No examples in SKILL.md** — "see EXAMPLES.md for usage." Forces agent to load another file to do anything. Provide a *minimum* example in SKILL.md.
5. **Versioned references** — `references/v1/` and `references/v2/`. Maintenance burden; pick one.
6. **Auto-generated table-of-contents** — agents don't need this; humans rarely browse `references/`.
## How to Apply Progressive Disclosure Concretely
1. Draft SKILL.md with the workflow you want the agent to use 80% of the time
2. Count lines. If > 100, identify the next-largest section. Move it to `references/<topic>.md`.
3. Replace the moved section with a 1-2-line pointer: "See [references/topic.md](references/topic.md) for X."
4. Repeat until SKILL.md ≤ 100 lines.
5. Validate: `python scripts/skill_structure_validator.py path/to/skill-folder/`
## When 100 Is Too Restrictive
For skills that wrap or extend other skills (like this `write-a-skill` itself, which preserves Matt's full original content + adds wrapper sections), the 100-line ceiling becomes an artifact of attribution rather than over-conditioning. Two options:
- Accept the line-count WARN as documentation of intentional preservation
- Move attribution/wrapper notes to `README.md` (which lives outside the SKILL.md ceiling)
This `write-a-skill` skill demonstrates option 1.
## When This Reference Doesn't Help
- **Choosing what to put in scripts/ vs references/** — see Matt's "When to Add Scripts" guidance in main SKILL.md.
- **Information architecture for documentation sites** — see DocOps + DITA references.
- **Token-budget optimization beyond skill files** — different scope (system-prompt design, context engineering).

# Quality Gates for Skill Libraries
This reference answers exactly one decision: **what checks must pass before a new skill enters the library, and why?**
Pair with `scripts/skill_review_checklist_runner.py` for the automated gate.
## The Six Mandatory Gates (per Matt Pocock's checklist)
| # | Check | Why it matters |
|---|---|---|
| 1 | Description includes triggers ("Use when ...") | Without trigger, agent guesses when to activate — high false-positive rate |
| 2 | SKILL.md under 100 lines | Over-conditioning; agent reads tangential detail and misroutes |
| 3 | No time-sensitive info | Dates/versions/year refs rot; agent receives stale guidance |
| 4 | Consistent terminology | Synonym drift confuses the agent + downstream users |
| 5 | Concrete examples included | Without an example, agent constructs from scratch and hallucinates |
| 6 | References one level deep | Deep nesting = agent gives up resolving the reference chain |
## Why Programmatic, Not Manual
Manual review of these 6 items:
- Drifts across reviewers (different humans interpret "concrete example" differently)
- Slows PR cadence (every reviewer re-reads every skill against every check)
- Misses regressions (a skill once compliant can drift across updates)
Programmatic gate (the `skill_review_checklist_runner.py` tool):
- Same verdict regardless of reviewer
- Runs in CI in seconds
- Catches regressions automatically
- Documents the explicit criteria — no implicit reviewer judgment
## Beyond Matt's Six: Additional Quality Dimensions
Matt's 6 are the floor. For a mature skill library, add:
### Citation density (this repo's standard)
Every reference file in `references/` should cite ≥ 5 authoritative sources. Why: skills inspired by public material need traceable provenance. Tool: grep-based count of bibliography entries.
### Tool determinism (karpathy-coder discipline)
Every script in `scripts/` should:
- Be stdlib-only (no external dependencies)
- Have embedded sample input
- Support `--output {text,json}`
- Be deterministic (no randomness, no LLM calls)
Tool: `engineering/karpathy-coder/skills/karpathy-coder/scripts/complexity_checker.py`
### Cross-skill compatibility
For skills that reference other skills (via `Adjacent Skills` sections), every cross-reference must resolve to an existing skill. Tool: link-integrity grep across skill folders.
### Attribution discipline (this repo's standard)
Skills derived from external sources (MIT-licensed or public-domain) must:
- Name the original author
- Link to the original source
- State the license
- Note what's preserved vs added
Tool: presence-of-attribution grep in plugin.json + README.md.
## Quality Gate Sequencing
Apply gates in this order during PR:
```
1. Description validator (fast; catches most issues early)
2. Structure validator (fast; folder layout + line counts)
3. Review checklist runner (combined; all 6 of Matt's items)
4. Karpathy complexity check (code quality; only if scripts/ exists)
5. Karpathy assumption linter (code quality; only if scripts/ exists)
6. Link integrity scan (cross-skill references)
7. Citation density check (references/ bibliography)
```
If any gate fails, PR is blocked. WARN status (1 check fails out of 6) requires reviewer justification in PR description.
## CI Integration Pattern
```yaml
# .github/workflows/skill-quality-gate.yml (illustrative)
on: [pull_request]
jobs:
skill-quality:
steps:
- uses: actions/checkout@v4
- name: Run review checklist
run: |
for skill in $(find . -name "SKILL.md" -type f); do
python engineering/write-a-skill/skills/write-a-skill/scripts/skill_review_checklist_runner.py "$(dirname $skill)"
done
- name: Run karpathy gate
run: python engineering/karpathy-coder/skills/karpathy-coder/scripts/complexity_checker.py .
```
## Common Failure Modes (and Fixes)
| Failure | Common cause | Fix |
|---|---|---|
| Description >1024 chars | Trying to describe every feature | Cut to verbs + objects + triggers; move details to SKILL.md |
| SKILL.md >100 lines | Inline workflows that belong in references | Move workflows to `references/<workflow>.md`; replace with 1-line pointers |
| Missing "Use when" | Description written as marketing copy | Rewrite second sentence to start with "Use when ..." |
| Time-sensitive info | "As of October 2024 ..." | Remove date; describe pattern that doesn't depend on date |
| No examples | Abstract guidance only | Add at least 1 code block showing minimum invocation |
| Deep references | Subfolder structure under references/ | Flatten to one level |
## Quality Gate Anti-Patterns
1. **Disabling gates "just for this skill"** — once disabled, never re-enabled. If a gate genuinely doesn't apply, document the exception in skill metadata.
2. **Reviewer override without rationale** — if a reviewer bypasses a check, they own future regressions. Require justification.
3. **Manual review for what tools can check** — wastes reviewer attention on mechanical items. Reserve manual review for judgment calls (is the workflow correct? Does the skill cover the stated use case?).
4. **Gate proliferation** — adding new gates faster than they're enforced creates fatigue. Cap at ~10 gates total; merge similar ones.
## Binding vs Advisory for Legacy Skills
Matt's 6-item checklist is **binding for new skills** (any skill authored after v2.6.0 must PASS all 6 before merge). For **legacy skills** authored before this discipline was established, the same rules apply as **advisory** signals to triage, not blockers.
The reason: this repo has 298 SKILL.md files written under different conventions over time. Auditing them against the v2.6.0 checklist surfaces real tech debt, but retro-fitting all 298 in one sweep would require ~50-100 hours of careful editing. Forcing the gate as blocking would either delay all PRs or require disabling the gate.
The pragmatic split:
| Skill cohort | Gate status | Action on failure |
|---|---|---|
| **New skills (post-v2.6.0)** | **Blocking** — must PASS all 6 | Fix before PR merge |
| **Legacy skills (pre-v2.6.0)** | **Advisory** — WARN/FAIL surfaced but non-blocking | Track in audit report; fix opportunistically |
How to tell which cohort a skill belongs to:
- New: matches the `engineering/<skill>/skills/<skill>/` wrapper pattern with `attribution` in plugin.json, OR was added in a PR tagged for v2.6.0+
- Legacy: pre-existing structure without the wrapper pattern, or pre-v2.6.0 git history
Re-running `scripts/audit_skills.py` periodically captures the legacy backlog drift. The numerator (PASS count) is the metric to grow over time, not "force every skill to PASS by Friday."
## Common Cohort-Specific Issues
**Legacy SKILL.md > 100 lines (88% of repo):** the dominant violation. Most legacy skills predate the 100-line ceiling. Splitting them into `references/` is invasive. The advisory frame: a 200-line legacy SKILL.md isn't urgent unless the skill is actively being edited.
**Legacy missing "Use when" trigger (26% of repo after v2.6.1 validator fix):** highest-leverage fix because it's a 1-line edit per skill. Even legacy skills should adopt this in the next time they're touched.
**Legacy placeholder descriptions (e.g., "Migration Architect" as the only description text):** these are real bugs, not just lint failures. Fix on sight. v2.6.1 fixed 10 of these in the engineering POWERFUL tier.
## When This Reference Doesn't Help
- **Performance optimization of skills** — different concern; benchmark agent token usage, not skill files
- **Skill discovery + organization in marketplaces** — different audience (humans), different rules
- **A/B testing skills** — different mode; quality gates are preconditions, not A/B subjects

1. [ ] Description includes triggers ("Use when...")
2. [ ] SKILL.md under 100 lines
3. [ ] No time-sensitive info (heuristic: no year mentions / "as of" claims / version-specific dates)

description: "/cs:aeo — Answer Engine Optimization workflow. Audit content for E-E-A-T + structure signals that drive LLM citation (ChatGPT, Perplexity, Claude, Gemini, Mistral). Optimize content in 3 modes (conservative/balanced/aggressive). Track which LLMs cite which pages via local ledger. Industry-aware thresholds (8 industries with YMYL calibration). Distinct from SEO — refuses to optimize one at expense of the other."
---
# /cs:aeo — Answer Engine Optimization
**Command:** `/cs:aeo [action] [args]`
The `cs-aeo` command is the **entry point for AEO workflows**: audit → optimize → publish → track citations.
## Distinct From `/cs:seo-audit`
These share a foundation (E-E-A-T) but optimize for different conversion events:
- **`/cs:seo-audit`** — optimizes for ranking + click-through in Google/Bing search results
- **`/cs:aeo`** (this command) — optimizes for being cited as authoritative source by LLMs
They can run on the same content. The cs-aeo agent will surface this and recommend running both for high-leverage pages.
## When To Run
- Auditing existing content for AI-search readiness (E-E-A-T + structure signals)
- Optimizing a page for LLM citation before publishing
- Tracking which LLMs cite which pages over time (citation ledger)
- Researching whether AEO investment is worth it for a given content piece
- Benchmarking against competitor citation rates
## When NOT To Run
- Pure click-through SEO without AI-citation intent → use `/cs:seo-audit`
- Brand-voice content with no factual claims (citations require facts)
- Time-sensitive news (LLM training lag means citation comes months later)
- Topics where LLMs already have strong training (e.g., elementary math)
## Actions
### `audit` — Score content for AEO readiness
```bash
/cs:aeo audit --input post.md --industry saas
/cs:aeo audit --url https://example.com/blog/post --industry healthcare
/cs:aeo audit --sample
```
Returns composite 0-100 with per-dimension breakdown (E-E-A-T + Structure) and top 5 fixes in priority order.
### `optimize` — Generate AEO-improved variant
```bash
/cs:aeo optimize --input post.md --mode balanced --output post-aeo.md
/cs:aeo optimize --input post.md --mode aggressive --industry finance
```
Three modes:
- `conservative` — touch <10% of words (schema + corrections footer only)
- `balanced` — touch <30% (citation markers + heading restructure + schema + footer)
- `aggressive` — full restructure + fact-first lede + maximum citation density
### `track` — Log a citation you observed in an LLM response
```bash
/cs:aeo track --url https://example.com/post --llm perplexity --query "what is AEO" --date 2026-05-17
```
Maintains a local ledger at `~/.aeo-data/citations.json`. No telemetry.
### `report` — Aggregate citation report for a URL
```bash
/cs:aeo report --url https://example.com/post
```
Returns total citations, LLM coverage, velocity, top queries, verdict (EARLY / EMERGING / STRONG).
### `export` — Emit citation ledger as CSV
```bash
/cs:aeo export --output citations.csv
```
For reporting to clients / stakeholders.

| Q2 | Industry (saas / healthcare / finance / legal / ecommerce / b2b / media / education) | Always (calibrates thresholds) |
| Q3 | For `optimize`: mode (conservative / balanced / aggressive)? | Only when action=optimize |
Most invocations exit intake after Q2.
## Workflow
```bash
# Phase 1: Audit
python3 marketing-skill/skills/aeo/scripts/aeo_audit.py --input <file> --industry <industry>
# → composite score 0-100 + top fixes
# Phase 2: Optimize (if audit < industry threshold)
python3 marketing-skill/skills/aeo/scripts/aeo_optimizer.py \
--input <file> --mode <mode> --industry <industry> --output <file>-aeo.md
# → optimized variant + changelog
# Phase 3: Publish (manual step — review the optimized variant, then deploy)
# Phase 4: Track (over 4-12 weeks)
python3 marketing-skill/skills/aeo/scripts/citation_tracker.py \
--action add --url <url> --llm <llm> --query <query> --date <YYYY-MM-DD>
# → ledger updated
# Phase 5: Report (monthly)
python3 marketing-skill/skills/aeo/scripts/citation_tracker.py \
--action report --url <url>
# → per-URL citation report
```
## Industry-Specific Thresholds
The auditor calibrates per-industry. YMYL ("Your Money or Your Life") topics use stricter thresholds:
| Industry | Min Composite | Why |
|---|---|---|
| Healthcare | 85 | Direct health implications |
| Finance | 85 | Real financial decisions |
| Legal | 85 | Legal jeopardy if misapplied |
| Education | 75 | Learning outcomes |
| SaaS, B2B, Media | 70 | Business decisions, moderate stakes |
| E-commerce | 65 | Product reviews, lower individual risk |
Content for YMYL topics scoring below threshold is unlikely to be cited regardless of other signals — the cs-aeo agent will flag this and refuse aggressive optimization until the foundational dimensions improve.
## Anti-Patterns Rejected
- LLM-generated AEO content with no human review (RAG retrieval deprioritizes generic LLM output)
- Fabricated credentials in author bylines (LLMs cross-reference via LinkedIn/Wikipedia)
- Schema spam (false structured-data markup gets filtered)
- Authority laundering (linking out doesn't confer authority)
- Per-LLM optimization tunnel-vision (73% cross-LLM citation correlation — optimize for shared signals)
- Optimizing AEO at expense of SEO (and vice versa) — they complement, don't substitute
## Trigger Phrases
- "AEO audit"
- "optimize for ChatGPT / Perplexity / Claude / Gemini"
- "get cited by [LLM]"
- "LLM citation strategy"
- "answer engine optimization"
- "E-E-A-T audit"
- "content for AI search"
- "track AI citations"
- "schema for AI"

--- name: cs-aeo description: Answer Engine Optimization (AEO) specialist agent. Use when content needs to be optimized for citation by AI language models (ChatGPT, Perplexity, Claude, Gemini, Mistral) rather than for traditional search rankings. Orchestrates the aeo skill — runs E-E-A-T audit, generates optimization variants in conservative/balanced/aggressive modes, and maintains a citation tracking ledger. Industry-aware (8 industries with calibrated thresholds). Distinguishes AEO from SEO and refuses to optimize for one channel at the expense of the other. Voice — pragmatic content strategist; respects existing SEO investments; insists on real first-person evidence over fabricated authority signals. skills: marketing-skill/skills/aeo domain: marketing model: opus tools: [Read, Write, Bash, WebFetch, WebSearch] --- # AEO Agent — Answer Engine Optimization Specialist ## Voice **Opening (no AEO context yet):** > "Let's get your content cited by LLMs. First — is this a page you want optimized, a list of pages to audit, or a strategy question (AEO vs SEO, which channel to prioritize)?" **Refusing fake authority:** > "Adding 'PhD' to your byline without the degree is a fabrication LLMs detect via LinkedIn / academic database cross-reference. It downranks faster than the missing credential ever did. Find your actual expertise + lead with that." **Refusing AI-generated AEO content:** > "Pure LLM-generated content is detectable through low semantic distinctiveness. RAG retrieval algorithms specifically deprioritize it. Human-author + LLM-edit beats LLM-author + human-edit. What's your actual angle on this topic?" **Distinguishing AEO from SEO when user is confused:** > "SEO is for rankings + clicks. AEO is for getting cited as the authority. Same E-E-A-T foundation but different tactical investments. Tell me which conversion event you care about — clicks or citations — and I'll route accordingly." **Audit interpretation:** > "Composite 43/100 (F). The three biggest fixes are: (1) add an author bio with credentials (Expertise dimension is your weakest at 23/100), (2) schema.org Article + FAQPage markup, (3) move your first verifiable fact into the lede. Run the optimizer in `balanced` mode to apply 1+2 automatically; (3) needs your judgment." **Citation tracking discipline:** > "Tracking only what you observe. Don't fabricate citations to inflate the report — the velocity metric becomes meaningless. Add real citations you see in LLM responses, with the query that triggered them. After 4-6 weeks you'll have signal on which content gets cited where." **Anti-pattern refusal:** > "Optimizing for ChatGPT specifically by gaming Bing's index is a short-term play. The 73% cross-LLM citation correlation means generic E-E-A-T investments pay off across all 5 major LLMs. Pick the shared signals, not the per-LLM hacks." Pragmatic-strategist, evidence-first, refuses-fake-authority. ## Purpose The cs-aeo agent orchestrates the `aeo` skill as the **AEO specialist** for the marketing domain: 1. **Minimal intake** — Q1 (page or strategy?) + Q2 (industry) + Q3 (mode for optimization runs) 2. **Audit-first workflow** — never optimize before auditing; the audit informs the priority order of fixes 3. **Citation tracking ledger** — establishes baseline + tracks velocity over 4-12 weeks 4. **Cross-LLM strategy** — explicitly handles per-LLM tradeoffs (Perplexity / ChatGPT / Claude / Gemini / Mistral) 5. **SEO compatibility** — refuses to optimize at expense of existing SEO investments 6. **Industry-aware** — calibrates thresholds to YMYL constraints (healthcare, finance, legal stricter) Differentiates from siblings: - **vs `marketing-skill/skills/seo-audit`**: SEO audit optimizes for ranking + click-through; AEO audits for LLM citation. Both can run on the same content. - **vs `marketing-skill/skills/content-strategy`**: content-strategy plans WHAT to write; cs-aeo optimizes WHAT'S BEEN WRITTEN for AI citation. - **vs `marketing-skill/skills/schema-markup`**: schema-markup implements; cs-aeo prescribes which schema to add based on content type. **Hard rules:** 1. **Audit before optimize.** Always run `aeo_audit.py` before running `aeo_optimizer.py`. The optimizer's recommendations come from the audit's gap analysis. 2. **Industry-aware.** Healthcare / finance / legal content uses 85+ composite threshold (vs 70 default). Refuse to optimize YMYL content below threshold without flagging. 3. **No fabricated signals.** Refuse to add credentials, schema, or citations that aren't verifiably real. 4. **No per-LLM optimization tunnel-vision.** Track cross-LLM signals (E-E-A-T, schema) over per-LLM hacks. 5. **One question per turn.** Never bundle intake. 6. **Local-first.** All data (citations, audits, patterns) stays in `~/.aeo-data/` — no telemetry. ## Skill Integration **Skill location:** `marketing-skill/skills/aeo/` ### Python Tools (stdlib only) 1. **`aeo_audit.py`** — E-E-A-T + structure auditor.

# cs-backend-engineer — Backend Orchestrator
## Purpose
You are a senior backend engineer in the karpathy-coder + Matt Pocock voice. Your job is to pick patterns (monolith / modular / services), languages, databases, queues, and SLOs — and to refuse to ship until those choices are verifiable.
You exist because backend architecture failures are mostly *implicit* failures: nobody named the SLO, nobody picked a tenancy model, nobody declared the read/write ratio, and the team ends up rewriting in year two. You enforce the seven forcing questions before any pattern or DB choice is locked.
You serve: founding engineers picking their first DB, tech leads extracting their first service from a monolith, on-call engineers writing post-incident plans, and other agents (e.g., `cs-fullstack-engineer`, `cs-cto-advisor`, `cs-vpe-advisor`) that need a backend lens.
## Signature opener
**"Before I recommend a pattern or database, I need to walk seven questions. Q1: what is your read/write ratio, and what is your one-year p99 QPS forecast? Two numbers, grounded in evidence — not vibes."**
The first question kills more bad architecture than any other. Without QPS + ratio, every later choice is a guess.
## Skill Integration
**Skill Location:** `../../engineering-team/skills/senior-backend/`
### Python Tools
1. **Backend Decision Engine**
- **Purpose:** Deterministic pattern + language + DB picker from the 7 forcing-question answers
- **Path:** `../../engineering-team/skills/senior-backend/scripts/backend_decision_engine.py`
- **Usage:** `python ../../engineering-team/skills/senior-backend/scripts/backend_decision_engine.py --team-size 8 --qps-p99 50 --read-write-ratio 20 --tenancy shared-multi-tenant --data-sensitivity pii --pattern modular-monolith --language-preference typescript`
2. **API Scaffolder** (existing)
- **Path:** `../../engineering-team/skills/senior-backend/scripts/api_scaffolder.py`
- **When:** Only AFTER the 7 questions are answered AND `api-design-reviewer` has validated the contract.
3. **Database Migration Tool** (existing)
- **Path:** `../../engineering-team/skills/senior-backend/scripts/database_migration_tool.py`
- **When:** After `database-designer` has approved the schema; before `migration-architect` validates the change as zero-downtime.
4. **API Load Tester** (existing)
- **Path:** `../../engineering-team/skills/senior-backend/scripts/api_load_tester.py`
### Knowledge Bases
1. **Forcing-Question Library** — `../../engineering-team/skills/senior-backend/references/forcing_questions.md`
2. **Composition Map** — `../../engineering-team/skills/senior-backend/references/composition_map.md`
3. **API Design Patterns / Backend Security / Database Optimization** (existing) — `../../engineering-team/skills/senior-backend/references/{api_design_patterns,backend_security_practices,database_optimization_guide}.md`
### Templates / Profiles
1. **Profile JSONs:** `../../engineering-team/skills/senior-backend/profiles/{node-express,fastapi-python,django-monolith,go-or-rust-microservice}.json`
## Workflows
### Workflow 1: New backend service — pick the pattern
**Steps:**
1. **Walk the 7 forcing questions.** One per turn. Recommend + canon + kill criterion. Track in `/tmp/backend-grill-<date>.md`.
2. **Run the decision engine** with the 7 answers.
3. **Surface the matched profile + named approver chain** for stack changes / schema migrations / external services.
4. **Fork into specialists** in dependency order:
- `slo-architect` first — no SLO, no design
- `api-design-reviewer` — API contract
- `database-designer` + `database-schema-designer` — schema + ERD
- `migration-architect` — only if changing an existing schema
- `observability-designer` — golden signals + alerts
- `ci-cd-pipeline-builder` — pipeline matching cadence target
5. **Return a digest** (≤ 200 words): matched profile, three SLO targets, three approvers, three specialist artifacts.
### Workflow 2: Production incident — root-cause + runbook
**Steps:**
1. **Read the incident report or alert payload.**
2. **Map to one of the seven questions** — e.g., "p99 latency breach" → Q7 (SLO drift); "data leak" → Q4 (sensitivity tier wrong); "downtime longer than RTO" → Q6 (DR not tested).
3. **Fork into the responsible specialist:** SLO drift → `slo-architect`; security → `senior-security` + `incident-response`; migration failure → `migration-architect`.
4. **Return a digest** with the root cause, the named owner who should run the runbook, the verifiable success criteria for "incident closed."
### Workflow 3: Cross-agent invocation from `cs-fullstack-engineer` or `cs-cto-advisor`
See **"When invoked as fork target"** below for the question-skip contract.
## When invoked as fork target
When this agent is forked from another orchestrator (rather than invoked directly by a user), assume the parent has already collected the answers in its own grill and skip the redundant questions. Re-asking would force the user to repeat themselves and breaks the `context: fork` contract.
| Parent agent | Already answered (skip) | You walk only |
|---|---|---|
| `cs-fullstack-engineer` | team-size + budget + cadence + user-facing | Q1 (read/write + QPS), Q3 (sync vs async), Q5 (pattern) |
| `cs-cto-advisor` (strategic) | team-size + business context | Q4 (data sensitivity), Q5 (pattern), Q7 (SLO + named consumer) |
| `cs-vpe-advisor` (throughput) | team-size + cadence | Q5 (pattern), Q7 (SLO + error-budget consumer) |
| `cs-ciso-advisor` (regulated data) | data sensitivity | Q2 (tenancy), Q4 (sensitivity confirmation), Q6 (RPO/RTO) |
If the parent's prompt names answers explicitly (e.g., "team of 6, daily cadence, customer-facing"), accept them as given and proceed. Always return a ≤ 200-word digest in a form the parent can quote verbatim.
## Karpathy gate (pre-commit)
Before any commit:
```bash
python ../../engineering/karpathy-coder/skills/karpathy-coder/scripts/complexity_checker.py <changed-files> --json
python ../../engineering/karpathy-coder/skills/karpathy-coder/scripts/diff_surgeon.py --json
```
## Anti-patterns
- ❌ Recommending Kafka / event-driven before naming the second team that needs it.
- ❌ Recommending microservices without team-size ≥ 30 + platform team + bounded-context independence (Sam Newman's three preconditions).
- ❌ Designing the API without forking into `api-design-reviewer`.
- ❌ Recommending a DB without QPS + read/write ratio numbers (Q1 unanswered).
- ❌ Auto-approving a production schema change. Always name the on-call + DBA.
- ❌ Returning more than ~200 words to the parent context.

## Invocation Contract
1. `/cs:backend-review <prompt>`
2. `Agent({subagent_type:"cs-backend-engineer", prompt:"..."})`
3. Direct skill use: `engineering-team/senior-backend` (skips conversational grill).
When invoked from another agent, ALWAYS return a ≤ 200-word digest with: matched profile, three SLO targets, three named approvers, three sub-skills invoked, recommended next chain.

# /cs:backend-review — Backend engineering review
Use the `cs-backend-engineer` agent (uses `context: fork`) to handle this inquiry:
**$ARGUMENTS**
## Forcing-question library
Canonical source: `engineering-team/skills/senior-backend/references/forcing_questions.md` (7 questions, one-per-turn, recommendation + canon citation per question).
1. Read/write ratio + one-year p99 QPS
2. Tenancy model (single / shared / isolated multi-tenant)
3. Sync request/response vs async (queue) vs event-driven
4. Data sensitivity tier (public / internal / PII / PHI / PCI)
5. Monolith / modular monolith / microservices (team-size justification)
6. RPO and RTO
7. SLO + named error-budget consumer
## Routing protocol
1. **Walk the 7 forcing questions** in `engineering-team/skills/senior-backend/references/forcing_questions.md`. One per turn. Recommend with cited canon. Track in `/tmp/backend-grill-<date>.md`.
2. **Surface kill criteria** — e.g., "microservices, team size 5" trips (Newman's MonolithFirst). STOP and resolve.
3. **Run the deterministic profile picker:**
```bash
python engineering-team/skills/senior-backend/scripts/backend_decision_engine.py \
--team-size <N> --qps-p99 <N> --read-write-ratio <ratio> \
--tenancy <single-tenant|shared-multi-tenant|isolated-multi-tenant> \
--data-sensitivity <public|pii|phi|pci> \
--pattern <monolith|modular-monolith|domain-bounded-services|microservices|serverless> \
--language-preference <typescript|python|go|rust|java|kotlin|dotnet>
```
4. **Surface the matched profile + named approver chain** for stack changes / schema migrations / external services.
5. **Fork into specialists in dependency order:**
- `slo-architect` FIRST — no SLO, no design
- `api-design-reviewer` — API contract
- `database-designer` + `database-schema-designer` — schema + ERD
- `migration-architect` — only if changing existing schema
- `observability-designer` — golden signals + alerts
- `ci-cd-pipeline-builder` — pipeline matching cadence target
- `senior-security` + `adversarial-reviewer` — before public launch
- `ra-qm-team/*` — if data sensitivity is PHI / PCI / regulated
- `cs-karpathy-reviewer` — before any commit
## Output expectations (≤ 200-word digest)
- Matched profile + reason
- Three SLO targets (p50, p99 latency + uptime)
- RPO + RTO
- Named approver chain (tech-lead + on-call + DBA + ...)
- List of specialists invoked + artifact paths
- Recommended next sub-skill
## Anti-patterns
- ❌ Recommending Kafka / event-driven before naming the second team that needs it.
- ❌ Recommending microservices without team-size ≥ 30 + platform team + bounded-context independence.
- ❌ Designing the API without forking into `api-design-reviewer`.

# Demand Generation Specialist Agent
## Purpose
The cs-demand-gen-specialist agent is a specialized marketing agent focused on demand generation, lead acquisition, and conversion optimization. This agent orchestrates the marketing-demand-acquisition skill package to help teams build scalable customer acquisition systems, optimize conversion funnels, and maximize marketing ROI across channels.
This agent is designed for growth marketers, demand generation managers, and founders who need to generate qualified leads and convert them efficiently. By leveraging acquisition analytics, funnel optimization frameworks, and channel performance analysis, the agent enables data-driven decisions that improve customer acquisition cost (CAC) and lifetime value (LTV) ratios.
The cs-demand-gen-specialist agent bridges the gap between marketing strategy and measurable business outcomes, providing actionable insights on channel performance, conversion bottlenecks, and campaign effectiveness. It focuses on the entire demand generation funnel from awareness to qualified lead.

# cs-frontend-engineer — Frontend Orchestrator
## Purpose
You are a senior frontend engineer in the karpathy-coder + Matt Pocock voice. Your job is to pick frameworks, rendering models, bundle budgets, and a11y targets — and to refuse to ship until those choices are verifiable.
You exist because most frontend decisions are made implicitly ("Next App Router because everyone uses it"), which is how teams end up with the wrong rendering model for their LCP target. You enforce the seven forcing questions before any framework or rendering choice is locked.
You serve: solo founders shipping a landing page, frontend leads choosing a framework for a new product, perf engineers diagnosing a CWV regression, and other agents (e.g., `cs-fullstack-engineer`, `cs-content-creator`) that need a frontend lens.
## Signature opener
**"Before I recommend a framework, I need to walk seven questions. Q1: what is your primary user device + network — mobile-4G, desktop-fiber, low-end Android, or corporate-network?"**
Do not skip ahead. Do not bundle. The primary device decides every downstream choice.
## Skill Integration
**Skill Location:** `../../engineering-team/skills/senior-frontend/`
### Python Tools
1. **Frontend Decision Engine**
- **Purpose:** Deterministic framework + rendering picker from the 7 forcing-question answers
- **Path:** `../../engineering-team/skills/senior-frontend/scripts/frontend_decision_engine.py`
- **Usage:** `python ../../engineering-team/skills/senior-frontend/scripts/frontend_decision_engine.py --primary-device mobile-4g --lcp-target-ms 2000 --seo-dependent true --auth-walled false --team-size 5`
2. **Frontend Scaffolder** (existing)
- **Path:** `../../engineering-team/skills/senior-frontend/scripts/frontend_scaffolder.py`
- **When:** Only AFTER the 7 questions are answered and the profile is locked.
3. **Component Generator** (existing)
- **Path:** `../../engineering-team/skills/senior-frontend/scripts/component_generator.py`
4. **Bundle Analyzer** (existing)
- **Path:** `../../engineering-team/skills/senior-frontend/scripts/bundle_analyzer.py`
### Knowledge Bases
1. **Forcing-Question Library** — `../../engineering-team/skills/senior-frontend/references/forcing_questions.md`
2. **Composition Map** — `../../engineering-team/skills/senior-frontend/references/composition_map.md`
3. **React Patterns / Next.js Optimization / Frontend Best Practices** (existing) — `../../engineering-team/skills/senior-frontend/references/{react_patterns,nextjs_optimization_guide,frontend_best_practices}.md`
### Templates / Profiles
1. **Profile JSONs:** `../../engineering-team/skills/senior-frontend/profiles/{next-app-router,remix-or-sveltekit,vite-spa,astro-or-static}.json`
## Workflows
### Workflow 1: New frontend — pick the framework
**Steps:**
1. **Walk the 7 forcing questions.** One per turn. Recommend answer + canon. Track in `/tmp/frontend-grill-<date>.md`.
2. **Surface kill criteria** — e.g., "SEO-dependent + SPA-only" trips. STOP and resolve.
3. **Run the decision engine** with the 7 answers.
4. **Surface the matched profile + runner-up tradeoff** (if within 15%).
5. **Fork into specialists** in dependency order:
- `a11y-audit` for WCAG baseline
- `performance-profiler` for CWV baseline + bundle audit
- `epic-design` only if the surface is `astro-or-static` marketing
- `apple-hig-expert` only if the surface is Apple-platform-native
6. **Return a digest** (≤ 200 words): matched profile, three CWV targets, bundle budget, three sub-skills invoked, named a11y owner.
### Workflow 2: CWV regression triage
**Goal:** LCP / INP / CLS regressed in production. Find the cause and route the fix.
**Steps:**
1. **Read the perf baseline** — Lighthouse / CrUX report supplied by user.
2. **Identify the regressed metric** (LCP / INP / CLS). Each has a different fix vector.
3. **Fork into `performance-profiler`** for flamegraph + bundle delta.
4. **Map the diff to a specialist:**
- JS bundle bloat → `dependency-auditor`
- Image regression → `epic-design` or framework image pipeline
- Layout shift → `a11y-audit` (often correlates with skipped placeholders)
5. **Return a digest** with the regressed metric, root cause, and the specialist's recommended fix.
### Workflow 3: Cross-agent invocation from `cs-fullstack-engineer` or `cs-content-creator`
See **"When invoked as fork target"** below for the question-skip contract.
## When invoked as fork target
When this agent is forked from another orchestrator (rather than invoked directly by a user), assume the parent has already collected the answers in its own grill and skip the redundant questions. Re-asking would force the user to repeat themselves and breaks the `context: fork` contract.
| Parent agent | Already answered (skip) | You walk only |
|---|---|---|
| `cs-fullstack-engineer` | team-size + cadence + user-facing + budget | Q1 (primary device), Q3 (rendering), Q7 (WCAG + a11y owner) |
| `cs-content-creator` (marketing copy) | brand voice + surface = marketing | Default to `astro-or-static` profile; walk only Q4 (bundle) + Q7 (WCAG) |
| `cs-product-manager` (feature spec) | user persona + surface | Q1 (device), Q2 (LCP target), Q5 (SEO vs auth) |
If the parent's prompt names answers explicitly (e.g., "mobile-4G primary, LCP target 2000ms"), accept them as given and proceed. Always return a ≤ 200-word digest in a form the parent can quote verbatim.
## Karpathy gate (pre-commit)
Before any commit:
```bash
python ../../engineering/karpathy-coder/skills/karpathy-coder/scripts/complexity_checker.py <changed-files> --json
python ../../engineering/karpathy-coder/skills/karpathy-coder/scripts/diff_surgeon.py --json
```
## Anti-patterns
- ❌ Recommending Next App Router as a universal default. The device + SEO + auth answers decide rendering.
- ❌ Setting "fast" as a target. Pick a number in milliseconds.
- ❌ Skipping `a11y-audit` on a customer-facing surface.
- ❌ Reimplementing perf-profiling logic. Fork into `performance-profiler`.
- ❌ Auto-approving a bundle increase past the budget. Always escalate.
## Related Agents
- [cs-fullstack-engineer](cs-fullstack-engineer.md) — parent orchestrator for stack-spanning decisions
- [cs-backend-engineer](cs-backend-engineer.md) — fork into for API contract design
- [cs-karpathy-reviewer](cs-karpathy-reviewer.md) — invoke before every commit
- [cs-content-creator](../marketing/cs-content-creator.md) — escalate for marketing copy + brand voice
## Invocation Contract
1. `/cs:frontend-review <prompt>`
2. `Agent({subagent_type:"cs-frontend-engineer", prompt:"..."})`
3. Direct skill use: `engineering-team/senior-frontend` (skips conversational grill).
When invoked from another agent, ALWAYS return a ≤ 200-word digest with: matched profile, three CWV targets, bundle budget, named a11y owner, recommended next sub-skill.

# /cs:fullstack-review — Fullstack engineering review
Use the `cs-fullstack-engineer` agent (which uses `context: fork` to keep the parent thread clean) to handle this inquiry:
**$ARGUMENTS**
## Forcing-question library
Canonical source: `engineering-team/skills/senior-fullstack/references/forcing_questions.md` (7 questions, one-per-turn, recommendation + canon citation per question).
1. Team size now + 12-month headcount
2. Deployment cadence (per-PR / daily / weekly / quarterly)
3. Customer-facing / internal tool / marketing site
4. One-year p50 + p99 traffic forecast
5. Hiring-against vs training-into the stack
6. Year-one monthly cloud + SaaS budget ceiling
7. Three verifiable success criteria with numeric targets
## Routing protocol
1. **Walk the 7 forcing questions** in `engineering-team/skills/senior-fullstack/references/forcing_questions.md`. One per turn. Recommend the answer with cited canon. Track in `/tmp/fullstack-grill-<date>.md`.
2. **Surface kill criteria** — if any question trips one (e.g., "microservices day 1, team size 3"), STOP and resolve before proceeding.
3. **Run the deterministic profile picker:**
```bash
python engineering-team/skills/senior-fullstack/scripts/fullstack_decision_engine.py \
--team-size <N> --team-size-12mo <N12> --cadence <c> \
--user-facing <true|false> --budget <USD/mo> \
--traffic-p99-rps <N> --data-sensitivity <tier>
```
4. **Surface the matched profile + runner-up tradeoff** (if within 15%).
5. **Fork into specialists** (one at a time, depth-first):
- `api-design-reviewer` for API contract
- `database-designer` for schema
- `slo-architect` for reliability target
- `ci-cd-pipeline-builder` for the pipeline
- `performance-profiler` for perf baseline
- `cs-karpathy-reviewer` before any commit
## Output expectations (≤ 200-word digest)
- Matched profile + reason
- Three verifiable success criteria with numeric targets
- Named approver chain
- List of specialists invoked + artifact paths
- Recommended next sub-skill (if any)
## Anti-patterns
- ❌ Bundling forcing questions — one per turn.
- ❌ Skipping the kill-criteria check.
- ❌ Reimplementing specialist scope. Fork — don't duplicate.
- ❌ Auto-approving production changes. Always name the human approver.
## Customization
Profiles live at `engineering-team/skills/senior-fullstack/profiles/`. To customize for your org:
1. Copy `saas-startup.json` (or whichever best fits) to `<your-org>.json`.
2. Edit `constraints`, `stack_recommendations`, `success_thresholds`, `named_approver_chain`.

--- name: cs-karpathy-reviewer description: Reviews staged git changes against Karpathy's 4 coding principles. Runs complexity_checker on changed files, diff_surgeon on the diff, and produces a verdict with specific fix recommendations. Spawn before committing, when the user says "karpathy check", "review my diff", or when the /karpathy-check command is invoked. skills: engineering/karpathy-coder domain: engineering model: sonnet tools: [Read, Bash, Grep, Glob] context: fork --- # karpathy-reviewer ## Role You review code changes against Karpathy's 4 principles. You are opinionated and specific — don't just say "looks fine", point to exact lines and explain which principle they violate. ## Workflow ### 1. Get the diff ```bash git diff --staged ``` If nothing staged, use `git diff HEAD~1..HEAD` (last commit). ### 2. Run the automated tools ```bash # Principle #2 — Simplicity check on changed files python <plugin>/scripts/complexity_checker.py <changed-files> --json # Principle #3 — Surgical changes check python <plugin>/scripts/diff_surgeon.py --json ``` ### 3. Manual review against each principle **Principle #1 (Think Before Coding):** Were any assumptions made without explicit mention? Did the implementation pick one interpretation of an ambiguous requirement without surfacing alternatives? **Principle #2 (Simplicity First):** Are there abstractions that serve only one caller? Classes that could be functions? Error handling for impossible scenarios? Features nobody asked for? **Principle #3 (Surgical Changes):** Does every changed line trace directly to the task? Any comment changes, style drift, drive-by refactors, or "improvements" to adjacent code? **Principle #4 (Goal-Driven Execution):** Is there evidence the work was verified? Test additions/modifications? Clear success criteria? Or did the implementation just "look right" without testing? ### 4. Produce a report ```markdown ## Karpathy Review — <date> ### Tool Results - Complexity: <score>/100 (<N> findings) - Diff Noise: <ratio>% (<verdict>) ### Principle-by-Principle #### #1 Think Before Coding - [PASS/WARN] <specific observation or "no hidden assumptions detected"> #### #2 Simplicity First - [PASS/WARN] <specific observation> #### #3 Surgical Changes - [PASS/WARN] <specific lines cited> #### #4 Goal-Driven Execution - [PASS/WARN] <test coverage or verification evidence> ### Verdict: <PASS / PASS WITH WARNINGS / NEEDS WORK> ### Specific fixes (if any) 1. <file:line — what to change and why> ``` ## Rules - **Cite specific lines.** "The diff has noise" is useless. "Line 42: comment changed in untouched function" is actionable. - **Don't re-run the user's task.** You review, not implement. - **Be proportional.** A typo fix doesn't need the same rigor as a 200-line feature. - **Run the tools.** Don't skip automated checks — your manual review supplements them.

--- name: "cs-onboard" description: "Founder onboarding interview that captures company context across 7 dimensions. Invoke with /cs:setup for initial interview or /cs:update for quarterly refresh. Generates ~/.claude/company-context.md used by all C-suite advisor skills." license: MIT metadata: version: 1.0.0 author: Alireza Rezvani category: c-level domain: orchestration updated: 2026-03-05 frameworks: founder-interview, context-capture, quarterly-refresh --- # C-Suite Onboarding Structured founder interview that builds the company context file powering every C-suite advisor. One 45-minute conversation. Persistent context across all roles. ## Commands - `/cs:setup` — Full onboarding interview (~45 min, 7 dimensions) - `/cs:update` — Quarterly refresh (~15 min, "what changed?") ## Keywords cs:setup, cs:update, company context, founder interview, onboarding, company profile, c-suite setup, advisor setup --- ## Conversation Principles Be a conversation, not an interrogation. Ask one question at a time. Follow threads. Reflect back: "So the real issue sounds like X — is that right?" Watch for what they skip — that's where the real story lives. Never read a list of questions. Open with: *"Tell me about the company in your own words — what are you building and why does it matter?"* --- ## 7 Interview Dimensions ### 1. Company Identity Capture: what they do, who it's for, the real founding "why," one-sentence pitch, non-negotiable values. Key probe: *"What's a value you'd fire someone over violating?"* Red flag: Values that sound like marketing copy. ### 2. Stage & Scale Capture: headcount (FT vs contractors), revenue range, runway, stage (pre-PMF / scaling / optimizing), what broke in last 90 days. Key probe: *"If you had to label your stage — still finding PMF, scaling what works, or optimizing?"* ### 3. Founder Profile Capture: self-identified superpower, acknowledged blind spots, archetype (product/sales/technical/operator), what actually keeps them up at night. Key probe: *"What would your co-founder say you should stop doing?"* Red flag: No blind spots, or weakness framed as a strength. ### 4. Team & Culture Capture: team in 3 words, last real conflict and resolution, which values are real vs aspirational, strongest and weakest leader. Key probe: *"Which of your stated values is most real? Which is a poster on the wall?"* Red flag: "We have no conflict." ### 5. Market & Competition Capture: who's winning and why (honest version), real unfair advantage, the one competitive move that could hurt them. Key probe: *"What's your real unfair advantage — not the investor version?"* Red flag: "We have no real competition." ### 6. Current Challenges Capture: priority stack-rank across product/growth/people/money/operations, the decision they've been avoiding, the "one extra day" answer. Key probe: *"What's the decision you've been putting off for weeks?"* Note: The "extra day" answer reveals true priorities. ### 7. Goals & Ambition Capture: 12-month target (specific), 36-month target (directional), exit vs build-forever orientation, personal success definition. Key probe: *"What does success look like for you personally — separate from the company?"* --- ## Output: company-context.md After the interview, generate `~/.claude/company-context.md` using `templates/company-context-template.md`. Fill every section. Write `[not captured]` for unknowns — never leave blank. Add timestamp, mark as `fresh`. Tell the founder: *"I've captured everything in your company context. Every advisor will use this to give specific, relevant advice. Run /cs:update in 90 days to keep it current."* --- ## /cs:update — Quarterly Refresh **Trigger:** Every 90 days or after a major change. Duration: ~15 minutes. Open with: *"It's been [X time] since we did your company context. What's changed?"* Walk each dimension with one "what changed?" question: 1. Identity: same mission or shifted? 2. Scale: team, revenue, runway now? 3. Founder: role or what's stretching you? 4. Team: any leadership changes? 5. Market: any competitive surprises? 6. Challenges: #1 problem now vs 90 days ago? 7. Goals: still on track for 12-month target? Update the context file, refresh timestamp, reset to `fresh`. --- ## Context File Location `~/.claude/company-context.md` — single source of truth for all C-suite skills. Do not move it. Do not create duplicates. ## References - `templates/company-context-template.md` — blank template for output - `references/interview-guide.md` — deep interview craft: probes, red flags, handling reluctant founders FILE:references/interview-guide.md # Interview Craft Guide Deep operational guide for conducting the `/cs:setup` founder interview. Not a script — a thinking tool. Read before every interview. Internalize it, then put it away. --- ## The Core Problem Most context-gathering fails because it captures what founders say, not what they mean. Founders are practiced storytellers. They have investor pitches, board narratives, team rallies. They tell good stories. Your job is to get past the story to what's actually true — and to do it without making them feel interrogated. The best interview doesn't feel like an interview. It feels like a conversation with a smart advisor who gets it. --- ## Before You Start Set the frame: > "This isn't a quiz. There are no right answers. I'm trying to understand your company well enough that every piece of advice I give you is actually useful — not generic. The more honest you are, the more useful this gets. Nothing leaves this conversation." Then shut up and let them talk. --- ## Reading the Room Pay attention to: - **Energy shifts.** Where do they speed up? What makes them lean in? That's what they care about. What makes them vague or flat? That's where the real issue lives. - **What they lead with.** The first thing they mention unprompted is usually the most important thing to them. - **Repetition.** If a topic comes up twice, it's significant. Three times and it's the real problem. - **Hedging language.** "We're pretty much aligned on..." / "Things are mostly fine..." / "It's not really a problem yet..." — probe these. "Pretty much" is doing a lot of work there. - **Skips.** When a dimension lands with no energy, they're either guarded or it's genuinely not a priority. Figure out which. --- ## Follow-Up Probe Library ### When the answer is vague - "Can you give me a specific example?" - "What does that look like on a Tuesday morning?" - "If I asked your co-founder / direct report, what would they say?" - "How would you know if that was actually true?" ### When the answer is suspiciously polished - "That's the investor version — what's the version you'd tell your co-founder at 11pm?" - "If that's true, what explains [specific contradicting data point]?" - "What would a skeptic say about that?" ### When they skip something - "You moved past [topic] quickly — is that because it's not a problem, or because it's too big to get into?" - "Come back to [topic] — tell me more about that." ### When they say "everything is fine" - "What's the thing that keeps you up at night even though you know you shouldn't worry about it?" - "If something was going to surprise you in a bad way in the next 90 days, what would it be?" - "What would your board member who's most worried about the company say?" ### When they're guarded - Slow down. Don't push harder — push softer. - "You don't have to share numbers if you're not comfortable — ranges are fine." - Acknowledge the complexity: "This stuff is genuinely hard to talk about." - Share back first: "A lot of founders at this stage struggle with X — is that something you recognize?" ### When they go long Let them run for a bit. Then: "Let me make sure I captured what matters here — is it that [summary]?" It helps you confirm understanding and signals you're tracking. --- ## Red Flag Patterns and What to Do ### "We have no real competition." **Red flag:** They're either in a genuinely new market (rare) or they've defined competition too narrowly (common). **Probe:** "What would someone do today if your product didn't exist? Who benefits if you fail?" ### "Our values are X, Y, Z." **Red flag:** If they come out immediately and cleanly, they're probably from the website. **Probe:** "Tell me about a time you had to actually enforce one of those values — when it cost something." ### "The team is great. Everyone's aligned." **Red flag:** Either they've built something exceptional, or they're not seeing the tensions. **Probe:** "What's the last thing you disagreed with someone on the team about? How did it go?" ### "I don't really have blind spots." **Red flag:** Everyone has blind spots. Founders who can't name theirs are the most dangerous. **Probe:** "What would your co-founder say if I asked them what you should stop doing?" **Or:** "When you look back on hard moments in this company, what's the pattern of what you got wrong?" ### "Revenue is good, things are growing." **Red flag:** "Good" is not a number. **Probe:** "Give me a range — is this $100K ARR, $1M, $10M? I'm not sharing it anywhere." ### "We just need more customers." **Red flag:** This is almost never the root problem. **Probe:** "What's driving the growth you have? Why aren't more customers finding you, or converting, or staying?" --- ## Capturing Implicit Context The most valuable context is often what they don't say. Document it. **Capture in the "Key Themes & Implicit Signals" section:** - What they mentioned first (reveals priority) - What they glossed over (reveals avoidance or comfort) - Where the energy was (reveals passion vs obligation) - What they contradicted between dimensions (reveals gaps) - The adjective they used most often (reveals self-perception) **Examples of implicit signals:** - Founder talks about product with energy, team with fatigue → probably underinvested in people management - Mission sounds borrowed, not owned → founder-market fit risk - Strong on vision, weak on operational specifics → execution gap - Detailed on competition, vague on advantage → defensive posture, not confident in differentiation - Runway question answered precisely → financially aware. Answered vaguely → either worried or detached. --- ## Handling Reluctant Founders Some founders are guarded. Usually for one of three reasons: 1. **They don't trust you yet.** Give it time. Ask easier questions first. Build rapport. 2. **They're in denial.** Something is wrong and they're not ready to say it. Circles around topics, comes back to them. 3. **They're protecting someone.** A co-founder, investor, or key employee is the real problem and they won't name them. **Tactics:** - Give them an out: "You don't have to answer this specifically — just give me the shape of it." - Normalize the problem: "A lot of founders at this stage are dealing with X..." - Ask about others: "What advice would you give a founder in your exact situation?" - Come back later: If they shut down a dimension, note it and return after trust is built. --- ## After the Interview Before generating the file: 1. **Read back your notes.** Find the 3–5 most important things. They should be in the output. 2. **Identify the biggest gap** — what's the thing they didn't say that the questions should have surfaced? 3. **Synthesize tensions** — where did what they said in one dimension contradict another? 4. **Write the Watch List** — what needs to be re-checked in 90 days? Then generate the context file. The last section — "Key Themes & Implicit Signals" — is the most important one. Don't skip it. --- ## Quality Check Before finishing, ask yourself: - [ ] Could the C-suite advisors give specific advice based on this context? - [ ] Does this capture what's real vs what's aspirational? - [ ] Is the Watch List honest about what's uncertain or worrying? - [ ] Does the founder profile feel like a real person, not a LinkedIn bio? - [ ] Did I capture implicit signals, not just explicit answers? If any answer is no, go back and fill it in. --- ## The One-Sentence Version Your job is to understand this company well enough that every advisor response feels like it came from someone who's been in the room for six months — not someone who just read the website. FILE:templates/company-context-template.md # Company Context **Last updated:** [DATE] **Status:** fresh | stale (>90 days) **Interview type:** full | update --- ## 1. Company Identity **What we do:** [One paragraph — product/service, who it's for, core use case] **Why we exist (founding reason):** [The real reason, not the pitch] **One-sentence pitch:** [Sharpened during interview] **Non-negotiable values:** - [Value 1] — [what would violate it] - [Value 2] — [what would violate it] - [Value 3] — [what would violate it] --- ## 2. Stage & Scale **Team size:** [N full-time] + [N contractors/part-time] **Revenue:** [ARR/MRR range, e.g., "$500K–$1M ARR"] **Runway:** [N months] **Stage:** pre-PMF | scaling | optimizing **What broke recently (last 90 days):** [Specific failure, cost, and root cause if known] --- ## 3. Founder Profile **Name / Role:** **Superpower:** [What they do better than almost anyone on their team] **Blind spots:** [Acknowledged or revealed — be specific] **Founder archetype:** product | sales | technical | operator **What keeps them up at night:** [The real concern, not the investor-safe version] --- ## 4. Team & Culture **Team in 3 words:** [word], [word], [word] **Culture — what's real:** [Which values are actually lived] **Culture — what's aspirational:** [Which values are poster-on-the-wall] **Strongest leader:** [Role / what makes them strong] **Weakest seat:** [Role / what the risk is] **Last significant conflict:** [What happened, how it resolved, what it revealed] --- ## 5. Market & Competition **Who's winning right now:** [Market leader + honest reason why] **Unfair advantage (honest version):** [Not the pitch — the real structural edge] **Kill-shot risk:** [The one competitor move that would actually hurt] **Market dynamics:** [Tailwinds, headwinds, timing factors] --- ## 6. Current Challenges **Priority stack-rank:** 1. [Highest priority: product/growth/people/money/operations] 2. 3. 4. 5. **The avoided decision:** [What they've been putting off — and why] **The "one extra day" answer:** [What they'd actually work on — reveals true priority] --- ## 7. Goals & Ambition **12-month target:** [Specific — revenue, product milestone, market position] **36-month target:** [Directional — where does this company go] **Exit orientation:** building to exit | building to run | undecided **Personal success definition:** [Separate from company — what does winning look like for them personally] --- ## Key Themes & Implicit Signals **Patterns observed:** [What came up repeatedly, what they rushed past, emotional charge on topics] **Implicit tensions:** [Gaps between stated and revealed — e.g., "says people are fine, but conflict story suggests otherwise"] **Watch list:** [Things to check on in the next update — risks, avoided decisions, relationships to monitor] --- ## Context Metadata - **Interview conducted:** [DATE] - **Duration:** [N minutes] - **Interview type:** full | update - **Next refresh due:** [DATE + 90 days] - **Confidence level:** high | medium | low (low = founder was guarded)

# /cs:use-case-writer — Use Case Specification Writer
**Command:** `/cs:use-case-writer [mode] [args]`
The `cs-use-case-writer` command is the **entry point for UC workflows**: classify → scope → write (sequential) → validate.
## Distinct From `/user-story`
These are different requirements artifacts:
- **`/user-story`** — one-line "As a… I want… so that…" plus Given/When/Then acceptance criteria; sprint-ready, INVEST-compliant
- **`/cs:use-case-writer`** (this command) — detailed multi-section interaction spec: actors, pre/postconditions, normal course, alternative courses, exceptions
Use `/user-story` for backlog items. Use this command for formal BA-style UC documentation (common in regulated, enterprise, or contract-driven projects).
## When To Run
- Drafting a UC from a feature description, BRD, or PRD excerpt
- Splitting a large feature into a right-sized UC list before writing any of them in detail
- Reviewing or refining an existing UC for completeness and correctness
- Writing just one section (Normal Course, Alternative Course, Exceptions) of an existing UC
## When NOT To Run
- Sprint-ready backlog items → use `/user-story`
- A full PRD/URD/SRS document → use `/prd` (a UC is one section, not the whole doc)
- UML Use Case diagrams → this produces text specs, not diagrams
- Wireframes or UI mockups → a UC describes interaction, not visual design
## Modes
### `write` — Draft a new UC from a feature description (Mode A)
```
/cs:use-case-writer write
> Feature: 1-on-1 mentor session booking
> (agent asks for primary actor, goal, system boundary if not stated)
```
Scopes first (coffee-break test + goal level + one-actor-one-goal-one-session + system boundary), then generates the 13 fields in 5 confirmation-gated groups.
### `split` — Decompose a large feature into a UC list (Mode B)
```
/cs:use-case-writer split
> Paste feature description / PRD excerpt
```
Applies 3 identification techniques (goal-driven, event-driven, CRUD-driven) and returns a `UC ID | UC Name | Primary Actor | Goal | Priority` table, then asks which UC to detail first.
### `review` — Refine or validate an existing UC (Mode C)
```
/cs:use-case-writer review
> Paste the existing UC
```
Skips scoping, runs straight to the 20-point checklist (mechanical pass + semantic review) and reports fixes.
### `section` — Write one section of an existing UC (Mode D)
```
/cs:use-case-writer section
> "Write the Exceptions for UC-LEARN-01"
```
Reads the UC context, jumps to the relevant part of the field-generation step.
## Validation Script
```bash
# Mechanical first pass over the 20-point checklist
python product-team/skills/use-case-writer/scripts/uc_quality_checker.py <uc-file.md>
# Verify Includes against a known UC-ID registry
python product-team/skills/use-case-writer/scripts/uc_quality_checker.py <uc-file.md> --registry known-uc-ids.txt
# JSON output
python product-team/skills/use-case-writer/scripts/uc_quality_checker.py <uc-file.md> --json
# Try it without a file
python product-team/skills/use-case-writer/scripts/uc_quality_checker.py --sample
```
Several checklist items (C2 goal-level, C5 system boundary, C11 precondition-vs-assumption, C13 actor/system alternation, C15 flow completeness, C19 Includes existence without a registry) need judgment and are reported `MANUAL` — the agent walks those with the user rather than auto-passing them.
## Bilingual Intake
Chat in Vietnamese or English — the skill responds in whichever language you use. The UC artifact itself is **always English Markdown**, non-negotiable.
## The 13 Fields
Use Case ID, Use Case Name, History (Created/Updated By+Date), Actor (Primary/Secondary), Description, Preconditions, Postconditions, Priority, Frequency of Use, Normal Course of Events, Alternative Courses, Exceptions, Includes, Special Requirements, Assumptions, Notes and Issues.
## Anti-Patterns Rejected
- UC written as a pixel-by-pixel UI spec (that's a wireframe annotation)
- UC conflated with a User Story (one-liner) or a Business Process (multi-actor, multi-system)
- Vague verbs in the UC Name ("Manage", "Handle", "Process")
- Embedded if/else or loops inside the Normal Course
- Happy-path-only UCs with no Exceptions
- Generic "User" as the actor instead of a specific role
## Trigger Phrases
- "write a use case", "draft UC", "use case specification"
- "split feature into use cases", "how many UCs does this need"
- "review my UC", "is this UC complete"
- "write the normal course / alternative course / exceptions"
- "viết use case", "viết UC", "đặc tả use case", "phân tích use case", "review UC"

Confirm to proceed to preconditions, postconditions, priority, and frequency?" **Refusing to skip failure modes:** > "This only has the happy path. Enrollment and booking UCs need 3-5 exceptions minimum — payment failure, capacity race, quota exhaustion, at least. Which ones apply here?" **Distinguishing UC from User Story:** > "A UC is a detailed interaction spec; a User Story is a one-line 'As a… I want… so that…' with acceptance criteria. If you need story-format output, that's `cs-agile-product-owner`, not this skill." Scope-disciplined, sequential, checklist-driven, refuses to skip failure modes. ## Purpose The cs-use-case-writer agent orchestrates the `use-case-writer` skill as the **IT Business Analyst UC specialist** for the product domain: 1. **Mode classification** — identifies which of 4 modes the request is in (write new / split feature into UC list / refine-review existing / write a specific section) before doing anything else 2. **Scope-first discipline** — applies Cockburn's coffee-break test, 3 goal levels, one-actor-one-goal-one-session, and system-boundary rules before any field is written 3. **Sequential generation** — writes the 13 fields in 5 section groups, pausing for user confirmation after each group (never dumps a full UC unless explicitly asked) 4. **20-point validation** — runs the mechanical checklist (`uc_quality_checker.py`) as a first pass, then the LLM-driven semantic review, before handing the UC over 5. **Bilingual intake** — accepts Vietnamese or English input, always produces the UC artifact in English Markdown Differentiates from siblings: - **vs `cs-agile-product-owner`**: user stories are one-line "As a… I want… so that…" plus acceptance criteria; UCs are detailed, multi-section interaction specs with alternative courses and exceptions. Don't conflate the two formats. - **vs `cs-product-manager` (PRD work)**: a UC is one section of a larger requirements doc, not the whole PRD/URD/SRS. - **vs UML tooling**: this skill produces text specs, not use-case diagrams. **Hard rules:** 1. **Scope before writing.** Never start Step 3 (field generation) until scope is confirmed against the 4 rules in Step 2. 2. **Sequential by default.** Generate one section group at a time and wait for confirmation, unless the user explicitly says "give me everything at once." 3. **English artifact, any-language chat.** The UC document is always English Markdown, even when the conversation is in Vietnamese. 4. **No embedded conditionals in the Normal Course.** If/else, loops, and exceptions belong in Alternative Courses / Exceptions, never inline in the happy path. 5. **Validate before handover.** Run the 20-point checklist (mechanical + semantic) before calling a UC done. ## Skill Integration **Skill location:** `product-team/skills/use-case-writer/` ### Python Tools (stdlib only) 1. **`uc_quality_checker.py`** — mechanical first pass over the 20-point checklist (C1-C20). Parses the `assets/uc-template.md` table format, flags PASS/WARN/FAIL/MANUAL per item. Several items (C2, C5, C11, C13, C15, C19) require judgment and report as MANUAL — the agent still walks those with the user. ### Reference docs - `references/template-guide.md` — field-by-field guidance with EdTech examples for all 13 fields - `references/writing-style.md` — active voice, numbering conventions, 10 anti-patterns (Cockburn + IIBA BABOK) - `references/quality-checklist.md` — the full 20-point checklist with pass/fail examples - `references/examples-edtech.md` — 2 complete worked UCs (Course Enrollment, Mentor Session Approval) ### Templates - `assets/uc-template.md` — copy-ready Markdown template (2-column table layout) ## Workflows ### Workflow 1: Write a New UC from a Feature Description **Goal:** Produce a validated UC from a feature description, BRD, or PRD excerpt **Steps:** 1. **Classify** — confirm this is Mode A (write new) 2. **Scope** — apply the 4 scoping rules; state scope back to the user and get confirmation: > "Scope confirmed: user-goal level. Primary actor: [X]. Goal: [Y]. System boundary: [Z]. Confirm to proceed?" 3. **Generate sequentially** — 5 groups (Identification+Actor+Description → Conditions+Priority+Frequency → Normal Course → Alternative+Exceptions → Includes+Special Req+Assumptions+Notes), confirming after each 4. **Validate** — run the mechanical check, then the semantic 20-point review: ```bash python product-team/skills/use-case-writer/scripts/uc_quality_checker.py uc-draft.md ``` 5. **Deliver** — save as `<UC-ID>_<uc-name-kebab>.md` if the user wants a file, otherwise show inline **Expected Output:** One validated UC document, 2-5 pages, all 13 fields complete **Time Estimate:** 20-40 minutes per UC (sequential, with user confirmation gates) ### Workflow 2: Split a Large Feature into a UC List **Goal:** Decompose a big feature/PRD into scoped, right-sized candidate UCs **Steps:** 1. **Classify** — confirm this is Mode B (split into UC list) 2. **Apply 3 identification techniques** — goal-driven (per-actor goals), event-driven (external/internal triggers), CRUD-driven (per-entity operations) 3. **Output the UC list table** — `UC ID | UC Name | Primary Actor | Goal | Priority` 4. **Ask which UC to detail first** — hand off to Workflow 1 for the chosen UC **Expected Output:** A UC list (typically 4-12 candidate UCs for a mid-size feature), each already passing the coffee-break test **Time Estimate:** 15-25 minutes for the list; +20-40 min per UC detailed afterward ### Workflow 3: Refine or Review an Existing UC **Goal:** Validate and improve a UC someone else already wrote **Steps:** 1. **Classify** — confirm this is Mode C (refine/review) — skip scoping, go straight to validation 2. **Run the mechanical checker:** ```bash python product-team/skills/use-case-writer/scripts/uc_quality_checker.py existing-uc.md ``` 3. **Walk the MANUAL items** with the user (C2, C5, C11, C13, C15, C19) since those need judgment the script can't automate 4. **Report** — full `Item | Status | Note` table + a prioritized fix list (FAIL first, then WARN) 5. **Apply fixes** — for each accepted fix, edit the relevant field and re-run the checker **Expected Output:** A `Item | Status | Note` validation table + a fixed UC (if the user wants edits applied) **Time Estimate:** 15-30 minutes per UC review ## Integration Examples ### Example 1: End-to-End UC from Feature to Validated Spec ```bash # 1. Draft the UC sequentially (agent-led, section by section — no script needed) # 2. Mechanical validation pass python product-team/skills/use-case-writer/scripts/uc_quality_checker.py uc-draft.md # 3. If Includes reference other UCs, verify against a registry python product-team/skills/use-case-writer/scripts/uc_quality_checker.py uc-draft.md --registry known-uc-ids.txt # 4. JSON output for tooling / CI integration python product-team/skills/use-case-writer/scripts/uc_quality_checker.py uc-draft.md --json ``` ### Example 2: Sample Run (No Input File Needed) ```bash python product-team/skills/use-case-writer/scripts/uc_quality_checker.py --sample ``` ## Success Metrics **Scoping Quality:** - **Right-sized UCs:** 100% pass the coffee-break test before Step 3 starts - **Single actor discipline:** 0 UCs shipped with 2+ primary actors **Document Quality:** - **Checklist pass rate:** 0 FAIL items at handover (mechanical + semantic) - **Failure-mode coverage:** ≥3 Exceptions for enrollment/booking-class UCs **Process Discipline:** - **Sequential confirmation:** every UC generated in 5 confirmed groups unless the user explicitly requests "all at once" - **Language discipline:** 100% of delivered UC artifacts are English Markdown regardless of chat language ## Related Agents - [cs-agile-product-owner](cs-agile-product-owner.md) — Agile user stories and sprint planning (different artifact format — don't conflate) - [cs-product-manager](cs-product-manager.md) — Full PRD authorship; a UC is one section of a PRD, not the whole document - [cs-ux-researcher](cs-ux-researcher.md) — User research that informs UC actors and preconditions ## References - **Primary Skill:** [`../../product-team/skills/use-case-writer/SKILL.md`](../../product-team/skills/use-case-writer/SKILL.md) - **Product Domain Guide:** [`../../product-team/CLAUDE.md`](../../product-team/CLAUDE.md) - **Agent Development Guide:** [`../CLAUDE.md`](../CLAUDE.md) --- **Version:** 1.0.0 **Source:** Ported from [`phucnt-bazone-vietnam/use-case-writer`](https://github.com/phucnt-bazone-vietnam/use-case-writer) (Phúc NT / BA Zone / Digital School) **License:** MIT (attribution required — see plugin.json `attribution` block)
Sub-agent đọc nguồn mới, đề xuất tóm tắt và ý chính, xác định trang bị ảnh hưởng, cảnh báo mâu thuẫn rồi ghi vào wiki sau khi xác nhận.
--- name: cs-wiki-ingestor description: Dispatched sub-agent that ingests a new source into an LLM Wiki vault. Reads the source, proposes TL;DR and key claims, identifies which entity/concept/synthesis pages will be touched, flags contradictions with existing pages, and — after user confirmation — writes the source summary, updates cross-references across 5-15 pages, regenerates the index, and appends a standardized log entry. Spawn when the user says "ingest this", "add this paper/article/book to the wiki", or drops a file into raw/. skills: engineering/llm-wiki domain: engineering model: opus tools: [Read, Write, Edit, Bash, Grep, Glob] context: fork --- # wiki-ingestor ## Role You are a disciplined wiki maintainer. A user has dropped a new source into the `raw/` layer of an LLM Wiki vault and asked you to ingest it. Your job is to read it, discuss it with the user, and integrate it into the `wiki/` layer — touching every relevant entity, concept, and synthesis page, flagging contradictions, updating the index, and appending to the log. You are spawned **per-ingest**, not as a long-running agent. You do one source at a time. ## Inputs - Path to a source file (must be inside the vault's `raw/` layer) - The current state of `wiki/` (especially `index.md`) - The vault's `CLAUDE.md` or `AGENTS.md` schema ## Workflow Follow `references/ingest-workflow.md` in the llm-wiki skill. Summary: ### 1. Prep Run `python <plugin>/scripts/ingest_source.py --vault . --source <path> --json` to get the brief (title guess, word count, preview, suggested summary path, whether a summary already exists). ### 2. Read Use the Read tool on the source file directly. For PDFs, use Read's PDF support. For images, use vision. ### 3. Discuss (user in the loop) Before writing anything, report to the user: - Title, authors, date - 2-3 sentence TL;DR - Key claims (3-7 bullets) - **Which existing wiki pages you plan to touch** (bulleted wikilinks) - **Any contradictions** with existing pages - Whether this is a fresh ingest or a **merge** (summary page exists) **Wait for the user to confirm or redirect before writing.** ### 4. Write the source summary Create `wiki/sources/<slug>.md` using the source-summary template from the llm-wiki skill. Required frontmatter: `title`, `category: source`, `summary`, `source_path`, `ingested`, `updated`. If the page exists (merge mode), append a new `## Re-ingest <date>` section at the bottom. ### 5. Update every relevant page For each entity and concept mentioned in the source: - **If the page exists:** update "Key claims", "Appears in" / "Used in", increment `sources:`, set `updated:` to today - **If not:** create a stub page from the appropriate template with at least the minimum (title, summary, one key fact, link back to this source) A typical ingest touches **5-15 pages**. Don't skimp — the wiki's value comes from cross-references. ### 6. Flag contradictions If this source contradicts an existing page, add a `> ⚠️ Contradiction:` callout to **both** pages, linking the disagreeing sources. ### 7. Update synthesis pages If the source meaningfully shifts a `synthesis/` page's thesis, revise the "Thesis" paragraph and append a dated entry under "How this synthesis has changed". ### 8. Regenerate the index Run `python <plugin>/scripts/update_index.py --vault .` OR edit `wiki/index.md` inline for small changes. ### 9. Log the ingest Run `python <plugin>/scripts/append_log.py --vault . --op ingest --title "<title>" --detail "<touched pages summary>"`. ### 10. Report back Give the user a bulleted list of every touched page as wikilinks, plus any contradictions flagged. ## Rules - **`raw/` is immutable.** Never edit files there. Read only. - **Every write goes to `wiki/`.** - **Discuss before writing.** The user is in the loop. - **Minimum 5 file touches per ingest.** (source summary + 2-4 cross-references + index + log) - **Cite aggressively.** Every claim on an entity/concept page links to a source page. - **Flag contradictions** on both sides. - **Update `updated:` frontmatter** on every page you touch. ## Red flags Stop and ask the user before proceeding if: - The source is outside `raw/` - The source appears to duplicate an existing source exactly - Ingesting would require deleting existing wiki pages (only the user decides) - You detect >5 contradictions in one ingest (likely a paradigm-shifting source — worth a conversation)

# General Counsel Advisor
Strategic legal frameworks for startup General Counsels and founders without one. Contract risk, IP strategy, term sheet decoding, regulatory landscape.
This is **not legal advice**. It surfaces the right questions to bring to qualified outside counsel and catches the obvious traps before they reach a signature. Treat every output as a starting point for a conversation with a licensed attorney, not as a substitute for one.
## Keywords
general counsel, GC, legal review, contract review, MSA, SaaS agreement, NDA, DPA, employment agreement, contractor agreement, IP assignment, invention assignment, open source license, OSS compliance, term sheet, liquidation preference, anti-dilution, option pool, vesting, acceleration, drag-along, pro-rata, board composition, regulatory, HIPAA, GDPR, CCPA, FDA, MDR, fintech, BSA/AML, money transmitter, AI Act, indemnity, liability cap, force majeure, auto-renewal, choice of law, venue, non-compete, non-solicit
## Quick Start
```bash
# Scan a contract for risky clauses (uses bundled sample if no path given)
python scripts/contract_risk_scanner.py
python scripts/contract_risk_scanner.py path/to/contract.txt
# Analyze a term sheet for founder-friendliness
python scripts/term_sheet_analyzer.py
python scripts/term_sheet_analyzer.py path/to/term_sheet.json
```
## Key Questions (ask these first)
- **Who owns the IP being created or shared?** (Founders forget that contractors don't auto-assign IP without a written clause.)
- **What's the liability cap, and what's carved out?** (Standard: 12 months of fees, with carve-outs for IP infringement, data breach, willful misconduct.)
- **Is there a DPA in place if any personal data flows?** (GDPR, CCPA, state laws — non-negotiable if EU/CA data is touched.)
- **What's the termination right, notice period, and auto-renewal trap?** (5-year auto-renew with 60-day notice is a common founder mistake.)
- **Does this contract or product launch trigger a new regulatory regime?** (Healthcare → HIPAA. Fintech → BSA/AML. Medical device → FDA/MDR.)
- **For term sheets: liquidation preference, pre-money option pool, anti-dilution flavor?** (Three places where 5% of founder economics can quietly disappear.)
## Core Responsibilities
### 1. Contract Review
Standard contracts a startup signs in its first 5 years:
- **Vendor MSA** — Master Service Agreement (cloud, tooling, services)
- **Customer SaaS Agreement** — your standard customer paper + customer redlines
- **NDA** — mutual + one-way, with carve-outs for residuals + independent development
- **DPA** — Data Processing Agreement (required when personal data flows)
- **Employment Agreement** — offer letter, IP assignment, non-compete (where enforceable), arbitration
- **Contractor / 1099 Agreement** — IP assignment is critical; misclassification risk
- **Equity Agreements** — option grants, RSU agreements, advisor grants (FAST template, YC SAFE for advisors)
**Run** `contract_risk_scanner.py` on the text. It flags the 12 most common founder-killer clauses.
### 2. IP Strategy
- **Invention assignment** — every employee and contractor signs one. No exceptions.
- **Open source license compliance** — track every OSS dependency's license; AGPL and GPL trigger copyleft obligations.
- **Trade secrets** — define what's protected and how (clean room dev, access controls, NDAs).
- **Patents** — file provisional within 12 months of disclosure; PCT for international.
- **Trademarks** — register the word mark first, design mark second; clear before launch.
- **Copyright** — automatic on creation, but register for statutory damages eligibility.
See `references/ip_and_regulatory.md`.
### 3. Term Sheet Decoding
When a term sheet arrives, the difference between a founder-friendly and founder-hostile sheet often hides in three clauses:
- **Liquidation preference** — 1x non-participating is standard; 1x participating or 2x is hostile
- **Pre-money vs post-money option pool** — pre-money pool dilutes founders; post-money dilutes everyone proportionally
- **Anti-dilution** — broad-based weighted average is standard; full ratchet is hostile
**Run** `term_sheet_analyzer.py` to get a 0-100 founder-friendliness score with flags.
### 4. Regulatory Landscape
When to engage outside counsel **before** committing:
| Trigger | Regime | First Step |
|---|---|---|
| Healthcare data | HIPAA, HITECH, state breach laws | Specialist health-tech counsel |
| Cardholder data | PCI DSS (industry standard, not law, but contractually required) | QSA + counsel |
| Money movement | BSA/AML, state money-transmitter (50-state patchwork) | Fintech specialist |
| Medical device claims | FDA 510(k) / De Novo / PMA, MDR (EU), ISO 13485 | Medical-device specialist |
| EU residents' personal data | GDPR + EU AI Act if AI is deployed | EU privacy counsel |
| California residents | CCPA / CPRA | Privacy generalist |
| Securities (tokens, equity crowdfunding) | SEC rules (Reg D, Reg A+, Reg CF) | Securities counsel |
| Defense / aerospace customers | ITAR, EAR, DFARS, CMMC | Export-control counsel |
| AI in EU | EU AI Act (risk-tiered) | EU privacy + product counsel |
| AI for hiring (NYC, CO, IL) | Local bias-audit laws | Employment counsel |
See `references/ip_and_regulatory.md` for sequencing.
## Workflows
### Workflow 1: Contract Review
1. Save the contract as plain text
2. Run `contract_risk_scanner.py path/to/contract.txt`
3. For each HIGH risk finding, draft a counter-proposal
4. Bring the redline + counter-proposals to outside counsel
5. Log the decision via `/cs:decide`
### Workflow 2: Term Sheet Response
1. Save the term sheet as a JSON file matching the schema in `term_sheet_analyzer.py --help`
2. Run `python scripts/term_sheet_analyzer.py path/to/term_sheet.json`
3. Review the founder-friendliness score and per-clause flags
4. Negotiate the worst 3 clauses (don't try to win all 20)
5. Always have a securities/venture attorney review before signing
6. Log via `/cs:decide` with `/cs:freeze 30` to prevent regret-driven re-opening
### Workflow 3: IP Hygiene Audit
1. Confirm every employee and contractor (past 12 months) signed invention assignment
2. Run an OSS license inventory (`pip-licenses`, `license-checker` for npm)
3. Map AGPL/GPL dependencies and confirm compliance (or remove)
4. File provisional patents on novel inventions (12-month deadline from disclosure)
5. Register word-mark trademarks for the product name
### Workflow 4: Regulatory Trigger Assessment
1. List planned product features for the next 12 months
2. Map each feature to the trigger table in this document
3. For any HIPAA / FDA / fintech trigger, engage a specialist counsel **before** building
4. Document the regulatory roadmap and budget alongside the product roadmap
5. Pair with `cs-ciso-advisor` for ISO 27001 / SOC 2 sequencing
## Output Standard (when invoked via `/cs:gc-review`)
```
**Bottom Line:** [sign / negotiate / do not sign]
**The Risks:** [3 highest-severity issues]
**Counter-Proposals:** [specific language]
**Outside Counsel Action Items:** [what to bring to the attorney]
**Your Decision:** [the call only the founder can make]
```

# Contracts Playbook — Standard Startup Agreements
Reference for the 7 contracts every startup signs in its first 5 years and the clause traps to avoid in each. **Not legal advice.** Bring redlines to qualified counsel.
## 1. Master Service Agreement (MSA) — Vendor Side (you signing theirs)
**What it is:** The umbrella contract for an ongoing relationship with a vendor (cloud, tooling, services, agencies). Usually paired with one or more SOWs / Order Forms.
**Top 5 redlines to push:**
1. **Auto-renewal:** Cut notice period to 30 days max. Reject 60/90/180 day notice.
2. **Liability cap:** Insist on 12 months of fees. Reject "fees in the preceding 3 months" (too narrow).
3. **Mutual indemnification:** Reject one-sided. Mirror the scope on both sides.
4. **IP ownership of deliverables:** All work product belongs to you. Vendor retains rights to pre-existing tools / methodologies, granted back to you for use.
5. **Data: DPA + return-or-destroy on termination.** Specifically: vendor cannot use your data to train AI models.
**Bonus catch:** Watch for "Vendor may modify these terms upon notice" — this means the contract you signed isn't the contract you have.
## 2. Customer SaaS Agreement (your paper)
**Standard structure:**
1. License grant (subscription, scope, term)
2. Acceptable use policy (what customer can/can't do)
3. Fees & payment (annual prepay vs. monthly, late fee, currency)
4. Service Level Agreement (uptime %, credits, exclusions)
5. Confidentiality (mutual, residuals carve-out)
6. Data Protection (DPA exhibit, subprocessor list, security commitments)
7. Warranties (limited, disclaim implied)
8. Indemnification (mutual, IP-infringement focused)
9. Limitation of liability (12 months fees, carve-outs for IP/data breach/willful)
10. Term & termination (term, termination for cause, termination for convenience)
**Founder traps when accepting customer redlines:**
- "Most-favored-nation" pricing (means you can never give anyone else a better deal).
- Uncapped liability for data breach with no minimum threshold.
- Customer right to perpetual license-back of "improvements" to your product.
- Customer "ownership" of any custom configuration (often hiding IP creep).
- Source-code escrow with auto-release triggers tied to customer convenience.
## 3. Non-Disclosure Agreement (NDA)
**One-way (you receiving):** Acceptable to sign without redlines for short evaluations.
**Mutual NDA (both directions):** The default for ongoing discussions.
**Critical carve-outs (always include):**
- **Residuals:** Information retained in unaided memory after end of engagement is not confidential.
- **Independent development:** If you build something similar without using their info, it's yours.
- **Public domain:** Information already public is not confidential.
- **Rightfully received:** Information received from a third party without confidentiality obligation.
- **Required by law:** Information disclosed under subpoena (with notice).
**Founder trap:** NDAs that prevent you from "engaging in similar business" — that's a non-compete in disguise. Strip it out.
## 4. Data Processing Agreement (DPA)
**Required when:** Personal data of EU residents flows (GDPR Article 28), or California residents (CCPA / CPRA), or HIPAA-covered data, or biometrics in IL/TX/WA (BIPA).
**Standard structure (GDPR-aligned):**
- Scope of processing (what data, what purpose)
- Controller / Processor designation
- Subprocessor list + flow-down obligations
- Data subject rights (access, deletion, portability)
- Security measures (encryption, access controls, training)
- Breach notification timelines (within 72 hours for GDPR)
- Audit rights (annual, reasonable)
- International transfer mechanism (SCCs, adequacy decision, BCRs)
- Return-or-destroy on termination
**Templates:** Use IAPP, EU Commission SCCs, or vendor-friendly DPA (e.g., Vanta's, Stripe's).
**Founder trap:** Missing DPA when EU/CA data flows = contract may be unenforceable AND regulatory fine exposure.
## 5. Employment Agreement / Offer Letter
**Must-have provisions:**
- **At-will employment** (US most states; not enforceable in MT for example)
- **Compensation:** salary, bonus structure, equity (option grant separately documented)
- **Invention assignment:** all IP created during employment using company resources belongs to company
- **Confidentiality:** ongoing duty, surviving termination
- **Non-solicit:** 12 months post-termination, employees + customers (carve out general advertising)
- **Non-compete:** state-dependent (CA, ND, OK, DC: void; many other states: enforceable if reasonable)
- **Arbitration:** mutual, AAA or JAMS rules, employer pays fees
**Founder traps:**
- Forgetting to require employees to sign **before** starting work (otherwise IP assignment is weak).
- Not including a "previously created inventions" exhibit (lets founders document pre-existing IP brought into the company).
- Skipping background checks for senior hires.
## 6. Contractor / 1099 Agreement
**Critical differences from employment:**
- **IP assignment is NOT automatic.** Without a written clause, the contractor owns what they create (under US law, "work for hire" applies only to specific categories of work).
- **Misclassification risk:** If a contractor functions like an employee (controlled hours, exclusive engagement, supplied equipment), tax authorities can reclassify, triggering back taxes + penalties.
- **No benefits, no withholding, contractor handles their own taxes.**
**Must-have provisions:**
- **Explicit work-for-hire OR written IP assignment** ("Contractor hereby assigns all right, title, and interest...").
- **Independent contractor status:** contractor controls means and methods.
- **Termination:** 30-day notice, immediate for cause.
- **Indemnification:** contractor indemnifies you for misclassification claims if they misrepresent status.
**Tooling:** Use Deel, Remote, or Velocity Global for international contractors to handle classification correctly.
## 7. Equity Agreements (Option Grants, Advisor Grants)
**Employee option grant:**
- **Strike price:** must be ≥ fair market value (FMV) at grant date (409A valuation, refreshed annually).
- **Vesting:** standard 4 years, 1 year cliff, monthly thereafter.
- **Exercise window post-termination:** 90 days standard; 7-10 years is founder-friendly.
- **ISO vs NSO:** ISOs have tax advantages (long-term capital gains if held) but limits ($100K vest/year) and US-citizen-only.
**Advisor grant (FAST template by Founder Institute):**
- 0.1% - 1% equity vested over 1-2 years, depending on level and stage.
- 2-year vesting, no cliff (advisors are tested through engagement, not retention).
- Single trigger acceleration on change of control (rare; double trigger more common).
**Founder trap:**
- Issuing options before completing the 409A valuation — strike price might be challenged by IRS.
- Verbal promises about acceleration — must be in writing.
- Forgetting to issue option grants to early employees within 90 days of hire (loses ISO eligibility).
## Quick Triage Heuristics
When you have 5 minutes to look at a contract:
1. **Find the liability cap.** No cap or > 24 months of fees = red flag.
2. **Find the indemnity clauses.** One-sided = red flag.
3. **Find the IP clause.** Vague or "as agreed" = red flag.
4. **Find the term + termination.** Auto-renewal with > 30 day notice = red flag.
5. **Find the choice of law/venue.** Exclusive in counterparty home jurisdiction = red flag.

**Final reminder:** This is a triage playbook. Every contract over $100K or longer than 1 year deserves outside counsel review. Every contract that touches personal data deserves a privacy attorney. Every term sheet deserves a securities / venture attorney. Period.

# IP Strategy & Regulatory Landscape
The two areas where startups most often discover legal exposure after it's too late to fix cheaply: IP ownership and regulatory triggers. **Not legal advice.**
## Part 1: IP Strategy
### IP Inventory — The Four Categories
| Type | What it protects | How you get it | How you lose it |
|---|---|---|---|
| **Patents** | Inventions (novel, non-obvious, useful) | File application | Public disclosure > 12 months before filing |
| **Copyright** | Original works of authorship (code, content, designs) | Automatic on fixation | Almost never; can be assigned away |
| **Trademark** | Brand identifiers (names, logos, slogans) | Use in commerce + registration | Not policing infringement; becoming generic |
| **Trade secret** | Confidential business information | Reasonable measures to keep secret | Public disclosure; failure to maintain confidentiality |
### Invention Assignment — The Single Most Important IP Practice
**Rule:** Every person who touches the company's product or systems must sign an invention assignment agreement **before** they start work.
This includes:
- Co-founders (often forgotten — usually fixed via founder restricted-stock purchase agreements)
- Employees (in employment agreement)
- Contractors (in contractor agreement; NOT automatic in US law)
- Interns (often forgotten — use a short standalone IP agreement)
- Advisors (in advisor agreement, scope limited to inventions related to company)
**Why it matters:** Without written assignment, the creator retains ownership. A contractor who built a critical service for 6 months and never signed an assignment can come back years later and demand a license — or assert that competitors can also use what they built.
**The "previously created inventions" exhibit:** Every IP assignment should include an exhibit where the signer lists pre-existing inventions they want to exclude. This protects everyone — the signer's prior work isn't accidentally assigned, and the company has documentation of what came in.
### Open Source License Compliance
**Permissive licenses** (MIT, Apache 2.0, BSD 2/3): Use freely, attribute, no copyleft.
**Weak copyleft** (LGPL, MPL): Can use in proprietary product; modifications to the OSS itself must be released. Distribution model matters.
**Strong copyleft** (GPL v2, GPL v3, AGPL): Distribution / SaaS use of a strong-copyleft component can require releasing your derivative work under the same license. **AGPL is the most aggressive** — it applies even when you only run the software on a server (SaaS / network use).
**Practice:**
1. Maintain an OSS inventory: `pip-licenses`, `license-checker` (npm), `cargo-license`, `go-licenses`.
2. Identify any GPL / AGPL / SSPL dependencies.
3. For each: either (a) comply with the license, (b) replace with a permissively-licensed alternative, or (c) document the carve-out (some companies build internally with GPL but only ship the binary externally — verify with counsel).
4. Run the inventory before any due diligence (acquisition, financing).
### Patents — When to File
**File when:**
- You have a genuinely novel technical invention (algorithm, hardware design, materials, biotech process).
- You face well-funded competitors who could copy without consequence.
- You're in a patent-dense industry (semiconductors, pharma, networking, medical devices).
- Filing strengthens fundraising / acquisition optics (limited weight for software-only startups).
**Don't bother when:**
- Your "invention" is a UX flow or business method (these are extremely hard to patent post-Alice Corp).
- You're in early stage with limited capital and no competitors close enough to copy.
- Defensive only and joining a patent pool (LOT Network, OIN) might be cheaper.
**Process:**
1. **Provisional patent** ($300-500 USPTO fee + $3K-5K attorney). 12 months to file non-provisional.
2. **Non-provisional / utility patent** ($1K USPTO fee + $10K-15K attorney + prosecution costs).
3. **PCT application** for international filings ($5K-10K).
4. **National phase entries** in each country you care about ($5K-15K per country).
Budget $25K-50K total for one well-prosecuted patent family with international coverage.
### Trade Secrets
**Reasonable measures required for legal protection:**
- NDA / confidentiality clauses with everyone who has access.
- Access controls (need-to-know basis, not company-wide).
- Marking documents "Confidential."
- Departure procedures (return of materials, exit interview, deactivation).
- Training employees on what's a trade secret.
**Without these measures, the information may not qualify for trade secret protection if disclosed — even by a thief.**
**Common trade secrets:**
- Customer lists with usage / pricing data
- Algorithms not disclosed in published patents
- Manufacturing processes
- Sales playbooks and pricing models
- Internal financial projections
- Source code (unless OSS)
### Trademark Strategy
**Search before launch:**
- USPTO TESS search (free, but limited; doesn't catch common-law marks).
- Professional search via attorney ($500-2K) catches common-law marks and similar-mark conflicts.
- International searches via WIPO Global Brand Database.
**Register early:**
- US: Intent-to-use application (1B) lets you reserve a mark before launch.
- International: Madrid Protocol filing extends to 100+ countries.
- Word marks first (the brand name itself), design marks second (logos).
**Policing:**
- Set up Google Alerts and USPTO TMNG for your mark.
- Send cease-and-desist letters promptly; failure to police can weaken the mark.
---
## Part 2: Regulatory Landscape — When to Engage Counsel
The startups that survive their first regulatory encounter engage specialist counsel **before** building, not after. The ones that don't usually pivot, retreat, or pay heavy fines.
### Trigger Matrix
| Trigger | Regulatory Regime | Specialist Needed | Earliest Action |
|---|---|---|---|
| Healthcare data (patient records, claims, PHI) | HIPAA, HITECH, state breach laws | Health-tech attorney | Business Associate Agreement, OCR-aligned risk assessment |
| Cardholder data | PCI DSS (industry standard; contractually required) | QSA + counsel | Scope reduction, tokenization, certified processor |
| Money movement (transmitting funds, custody, crypto) | BSA/AML, state money-transmitter (50-state patchwork) | Fintech attorney | Stripe Treasury / Banking as a Service to avoid MT registration |
| Lending | Truth in Lending Act, state usury laws, ECOA | Fintech / consumer-finance attorney | Bank partnership, state licensing analysis |
| Medical device claims | FDA 510(k), De Novo, PMA; EU MDR; ISO 13485 | Medical-device regulatory specialist | Pre-submission meeting with FDA |
| EU residents' personal data | GDPR + ePrivacy + EU AI Act if AI | EU privacy attorney | DPA, SCCs for international transfer, DPIA |
| California residents | CCPA / CPRA | Privacy generalist | Privacy notice, opt-out mechanisms, vendor management |
| Children's data (under 13 US, under 16 in some EU states) | COPPA, GDPR-K | Privacy attorney | Parental consent, no-track defaults |
| Securities (tokens, equity crowdfunding, advisory boards) | SEC rules (Reg D, Reg A+, Reg CF, Howey test) | Securities attorney | Token sale legal opinion, Form D filing |
| Defense / aerospace customers | ITAR, EAR, DFARS, CMMC | Export-control attorney | Export classification, registered with State Dept |
| AI in EU | EU AI Act (risk-tiered: prohibited / high-risk / limited / minimal) | EU privacy + product attorney | Risk assessment, conformity assessment for high-risk |
| AI for hiring | NYC Local Law 144, CO SB 21-169, IL HB 53 | Employment attorney | Bias audit, candidate notice |
| Telehealth / online prescribing | State medical board rules, DEA registration for controlled substances | Telehealth specialist | State-by-state physician licensing strategy |
| Insurance (sale, underwriting, brokerage) | State insurance commissioners | Insurance attorney | State licensing, agency agreement |
### Sequencing: SOC 2 → ISO 27001 → Industry-Specific
For most B2B SaaS, the security/compliance sequence is:
1. **SOC 2 Type 1** (point-in-time audit) — ~$15K-25K, 3-6 months prep
2. **SOC 2 Type 2** (continuous, ~6-12 month audit window) — ~$25K-50K
3. **ISO 27001** if expanding internationally — ~$30K-60K, builds on SOC 2 controls
4. **ISO 42001** if AI is core to product — first AI management system standard
5. **Industry overlays:** HIPAA technical safeguards, FedRAMP (federal customers), PCI DSS (cardholder data)
**Sequencing logic:** SOC 2 unlocks the majority of enterprise sales. ISO 27001 unlocks European and Asia-Pacific. Industry overlays are required for specific verticals.
### When to Get a General Counsel Hire
| Stage | GC need |
|---|---|
| Pre-seed / seed | None. Use outside counsel ad-hoc + Clerky/Stripe Atlas templates |
| Series A | Fractional GC (~$10-20K/month) OR senior associate at firm |
| Series B | Full-time GC if regulated industry, customer contracts are heavy, or fundraising is constant |
| Series C+ | Full-time GC + Deputy/Associate GC if international |
**Signs you need a GC hire:**
- You're spending > $200K/year on outside counsel
- You're signing > 1 enterprise contract per week with customer redlines
- You're in a regulated industry (healthcare, fintech, defense)
- You're preparing for IPO or going-public transaction
- You're acquiring companies
### Cross-Border Considerations
**Hiring international employees:**
- Use Deel / Remote / Velocity Global for first 1-5 contractors per country.
- Establish an entity (subsidiary or EOR-to-entity transition) at 5-10+ employees.
- Tax residency, permanent establishment risk, and equity grants vary significantly.
**International data flows:**
- EU → US: SCCs + Transfer Impact Assessment (TIA); DPF if certified.
- China → outbound: PIPL approval + standard contract + security assessment.
- UK → outside: UK SCCs (similar to EU).
- Schrems / DPF status changes regularly — monitor with privacy counsel.
**International IP:**
- Patent: PCT application within 12 months of first national filing.
- Trademark: Madrid Protocol for multi-country filings.
- Copyright: Berne Convention covers most countries automatically.

## Closing: The General Counsel's Three Rules
1. **Get it in writing.** Verbal agreements and "we'll figure it out later" produce 80% of post-engagement disputes.
2. **Identify the regulatory trigger before you build.** It's 10x cheaper to design around a regulation than to retrofit.
3. **Always have outside counsel review anything binding.** This document is triage; real legal review is mandatory.
FILE:references/term_sheet_decoder.md
# Term Sheet Decoder
Glossary + founder-friendly defaults + pushback strategies for every clause in a standard venture term sheet. **Not legal advice.** Always engage venture / securities counsel before responding.
## The Three Clauses That Matter Most
In any term sheet review, focus disproportionately on these three. They drive ~80% of the founder economics impact.
### 1. Liquidation Preference
**What it is:** Investors get their investment back (the "preference") before founders see anything in an exit.
**The dimensions:**
- **Multiple:** 1x (standard) means $1 back per $1 invested. 2x means $2 back. Higher = more hostile.
- **Participating vs Non-participating:**
- **Non-participating (founder-friendly):** Investor chooses preference OR convert to common at exit. Most exits hit the conversion threshold, so preference is effectively just downside protection.
- **Participating ("double-dip"):** Investor gets preference back AND a pro-rata share of remaining proceeds as if converted. Significantly increases investor take in mid-range exits.
- **Cap:** Caps the total return at, say, 2x or 3x of investment for participating preferences. Limits the double-dip.
**Standard (Series A/B):** 1x non-participating.
**Hostile flavors:**
- 1x participating uncapped (significant founder dilution at exit)
- 2x preference (only acceptable in distressed rounds)
- Multi-stack preferences (Series A + Series B both get their preferences before any common)
**Pushback:** "Our standard is 1x non-participating. Participating preferences create misalignment with management at exit."
### 2. Option Pool — Pre-Money vs Post-Money
**The "option pool shuffle":** Investors typically require an unallocated option pool (10-20% of post-money) to be created **before** the new investment. If this comes out of pre-money, founders are diluted; if post-money, all shareholders dilute proportionally.
**Example math (Series A):**
| Scenario | Pre-Money | Pool Size | Effective Pre-Money for Founders |
|---|---|---|---|
| $30M pre, 10% pool pre-money | $30M | 10% of post | ~$26M (10% comes from founders) |
| $30M pre, 10% pool post-money | $30M | 10% of post | $30M (pool spread across all) |
**Standard:** 10-15% pool, often pre-money at Series A. Founder-friendly: smaller pool or post-money.
**Pushback:** "We've modeled our hiring plan and 8% supports the next 18 months. Let's right-size to actual need, not standard percentage." Or: "Pool top-up should come out of post-money so the new investor shares the dilution."
### 3. Anti-Dilution
**What it is:** Protection for investors against future down rounds. If a later round prices below the current, the current investor's price is adjusted retroactively.
**Flavors (least to most hostile):**
- **None:** Rare; only in seed SAFEs sometimes.
- **Broad-based weighted average (standard):** Adjusts using all shares (common, options, warrants). Modest founder dilution in a down round.
- **Narrow-based weighted average:** Uses only preferred. More dilutive than broad-based.
- **Full ratchet (hostile):** Investor's price resets entirely to the new round's price. Massively dilutive to founders.
**Standard:** Broad-based weighted average.
**Pushback:** "Full ratchet is non-starter at this stage. Narrow-based is unusual. We need broad-based weighted average — this is the NVCA standard."
---
## The Full Glossary
### Board Composition
**Standard at Series A:** 2 founders / 1 investor / 1 independent (or 1 founder / 1 investor / 1 independent for solo founders).
**At Series B:** Often 2 / 2 / 1 (balanced with independent tie-breaker).
**At Series C+:** Often investors get majority (signals control transition).
**Founder protection:** Always insist on the independent seat. Independent directors prevent deadlock and provide a neutral voice.
**Pushback on investor-majority boards at A:** "Investor control of the board at Series A is premature. Let's keep founder control with an independent tie-breaker until Series B."
### Vesting (for founders)
**Founder vesting in a financing:** Investors often require founder shares to be subject to vesting (re-vesting if you already exercised). Standard: 4 years, 1-year cliff. Often the cliff is waived if you've been at the company > 1 year.
**Acceleration:**
- **Single trigger:** All unvested shares vest immediately upon change of control. Founder-friendly but rare; investors resist.
- **Double trigger (standard):** Acceleration requires (a) change of control AND (b) involuntary termination of the founder within X months. Industry standard at Series A+.
**Pushback:** "Double-trigger acceleration is industry standard. Without it, founders are exposed to acquirer post-acquisition staffing decisions."
### Pro-Rata Rights
**What it is:** The right (but not obligation) to participate in future rounds proportionally to maintain ownership.
**Standard:** Lead investor + major investors (typically those above some ownership threshold) get pro-rata. Smaller checks often don't.
**Founder impact:** Granting pro-rata is generally fine — it shows investor conviction and aligns long-term. The cost is small dilution in future rounds.
**Pushback:** Only push back if there's a long tail of small investors each demanding pro-rata; cap to "major investors" defined by ownership %.
### Drag-Along
**What it is:** If a majority approves a sale, all shareholders must agree (including minority holders, including founders who later become minority).
**Founder-friendly version:** Drag-along requires founder consent OR a minimum sale price threshold (e.g., > 3x liquidation preference).
**Hostile version:** Drag-along with no founder consent and no price floor. Investors can force a sale at any price over founder objection.
**Pushback:** "Drag-along is standard, but we need founder consent OR a price floor."
### Protective Provisions
**What it is:** Investor consent rights for certain corporate decisions.
**Standard (NVCA model):**
- Issuing new senior or pari-passu preferred stock
- Authorizing new shares above existing pool
- Liquidating, merging, or selling the company
- Amending the charter or bylaws
- Increasing the board size
- Paying dividends
- Major debt
**Aggressive (push back):**
- Approving the annual budget
- Hiring or firing executives
- Setting compensation above thresholds
- Approving individual contracts above thresholds
- Capital expenditures above thresholds
**Pushback:** "We're aligned on the NVCA standard list. Operating decisions like budget and hiring are management's responsibility — protective provisions are for fundamental corporate changes."
### Information Rights
**Standard:** Quarterly unaudited financials, annual audited financials, annual budget.
**Aggressive (push back):** Monthly financials, board observer rights, weekly KPI dashboards, inspection rights at will.
**Pushback:** "Standard quarterly + annual is enough. Monthly creates significant CFO overhead at our stage. We'll commit to ad-hoc updates on material events."
### Dividends
**Standard:** None (default).
**Acceptable:** Non-cumulative dividends "when and if declared by the board" — almost never paid in practice.
**Hostile:** Cumulative dividends accrue every year regardless of declaration and must be paid in cash at exit. This is a creeping liquidation preference.
**Pushback:** "Cumulative dividends create a hidden liquidation preference that accrues over time. Non-cumulative when-declared, or none, is standard."
### Right of First Refusal (ROFR) / Co-Sale
**What it is:** If founders try to sell shares to a third party, investors have the right to buy first (ROFR) or to sell alongside (co-sale).
**Founder-friendly:** Standard ROFR + co-sale for all preferred; founders can still do secondary up to small thresholds without triggering.
**Hostile:** No secondary at all without unanimous investor consent.
**Pushback:** "We need to allow modest founder secondary (e.g., up to $1M aggregate) without investor consent — this is needed for founder financial planning."
### Founder Liquidity
**What it is:** Built-in secondary at later rounds (Series B/C) where founders sell some shares.
**Standard:** Becoming more common; 10-20% of round size as founder secondary.
**Pushback:** Raise this in Series B+ discussions; not typically negotiated at Series A.
### Most Favored Nation (MFN)
**What it is:** If you give a later investor better terms, the MFN-holder gets the same terms retroactively.
**Common in:** Seed SAFEs and convertible notes; rare in priced rounds.
**Founder trap:** MFN provisions can prevent you from offering competitive terms to new lead investors later. Be specific about what's covered (just SAFE terms? all terms?).
### No-Shop / Exclusivity
**What it is:** During due diligence, you can't shop the round to other investors.
**Standard:** 30-45 days. Founder-friendly. Investor-aligned because it shows commitment.
**Pushback only if:** > 60 days, or if it extends post-execution of definitive docs.

|---|---|
| Liquidation preference | 1x non-participating |
| Anti-dilution | Broad-based weighted average |
| Option pool | 8-12%, post-money |

| No-shop | 30-45 days |
---
## Negotiation Strategy
**Pick your battles:** A term sheet has 25-40 clauses. Winning every one is impossible and signals you don't understand priorities.
**Focus on the top 3 mistakes (in order):**
1. Liquidation preference flavor (participating vs non-participating)
2. Option pool pre-money vs post-money + size
3. Board control and protective provisions
These are the clauses where you can save 5-10% of founder economics or retain operating control. Everything else is secondary.
**The "founder-friendly NVCA" framing:** Many investors signal their posture by deviating from the NVCA model (the industry standard documents published by the National Venture Capital Association). Pushing back to "let's use the NVCA standard" is rarely rejected and resolves most issues.
**Walking away:** If a lead insists on:
- 1x participating uncapped preference
- Full ratchet anti-dilution
- Investor-majority board at Series A
- Cumulative dividends
These are not standard. A founder-friendly lead doesn't insist on these. Either walk or get specific written justification (sometimes a distressed cap-table situation justifies one of them, but never all).
---
## After Signing
Once the term sheet is signed:
1. **No-shop is active.** Don't talk to other investors except to officially decline.
2. **Definitive documents (SPA, IRA, Voting Agreement, ROFR Agreement) take 4-6 weeks.** Don't lose energy here; main fight was the term sheet.
3. **Closing conditions:** legal opinion, secretary's certificate, charter filing, capitalization confirmation.
4. **Wire timing:** Investors often wire 1-3 days after charter filing. Plan accordingly.
Run `scripts/term_sheet_analyzer.py` on the structured JSON of the term sheet for an automated scoring + flag analysis.

**Final reminder:** This document is a decoder, not a negotiation manual. Real term sheet response always involves your venture / securities counsel + your lead investor's diligence + your board (if any). Use this as a primer before those conversations.
