Codex CLI requires YAML frontmatter (---) in SKILL.md files. 6 skills were missing frontmatter entirely; laravel-verification had a bare colon in its description causing an invalid YAML parse error.

# Product Lens — Think Before You Build
|
||
|
||
## When to Use
|
||
|
||
- Before starting any feature — validate the "why"
|
||
- Weekly product review — are we building the right thing?
|
||
- When stuck choosing between features
|
||
- Before a launch — sanity check the user journey
|
||
- When converting a vague idea into a spec
|
||
|
||
## How It Works
|
||
|
||
### Mode 1: Product Diagnostic
|
||
|
||
Like YC office hours but automated. Asks the hard questions:
|
||
|
||
```
|
||
1. Who is this for? (specific person, not "developers")
|
||
2. What's the pain? (quantify: how often, how bad, what do they do today?)
|
||
3. Why now? (what changed that makes this possible/necessary?)
|
||
4. What's the 10-star version? (if money/time were unlimited)
|
||
5. What's the MVP? (smallest thing that proves the thesis)
|
||
6. What's the anti-goal? (what are you explicitly NOT building?)
|
||
7. How do you know it's working? (metric, not vibes)
|
||
```
|
||
|
||
Output: a `PRODUCT-BRIEF.md` with answers, risks, and a go/no-go recommendation.
|
||
|
||
### Mode 2: Founder Review
|
||
|
||
Reviews your current project through a founder lens:
|
||
|
||
```
|
||
1. Read README, CLAUDE.md, package.json, recent commits
|
||
2. Infer: what is this trying to be?
|
||
3. Score: product-market fit signals (0-10)
|
||
- Usage growth trajectory
|
||
- Retention indicators (repeat contributors, return users)
|
||
- Revenue signals (pricing page, billing code, Stripe integration)
|
||
- Competitive moat (what's hard to copy?)
|
||
4. Identify: the one thing that would 10x this
|
||
5. Flag: things you're building that don't matter
|
||
```
|
||
|
||
### Mode 3: User Journey Audit
|
||
|
||
Maps the actual user experience:
|
||
|
||
```
|
||
1. Clone/install the product as a new user
|
||
2. Document every friction point (confusing steps, errors, missing docs)
|
||
3. Time each step
|
||
4. Compare to competitor onboarding
|
||
5. Score: time-to-value (how long until the user gets their first win?)
|
||
6. Recommend: top 3 fixes for onboarding
|
||
```
|
||
|
||
### Mode 4: Feature Prioritization
|
||
|
||
When you have 10 ideas and need to pick 2:
|
||
|
||
```
|
||
1. List all candidate features
|
||
2. Score each on: impact (1-5) × confidence (1-5) ÷ effort (1-5)
|
||
3. Rank by ICE score
|
||
4. Apply constraints: runway, team size, dependencies
|
||
5. Output: prioritized roadmap with rationale
|
||
```
|
||
|
||
## Output
|
||
|
||
All modes output actionable docs, not essays. Every recommendation has a specific next step.
|
||
|
||
## Integration
|
||
|
||
Pair with:
|
||
- `/browser-qa` to verify the user journey audit findings
|
||
- `/design-system audit` for visual polish assessment
|
||
- `/canary-watch` for post-launch monitoring
