product-lens
Use this skill to validate the "why" before building, run product diagnostics, and pressure-test product direction before the request becomes an implementation contract.
npx skills add mturac/everything-openai-codex --skill product-lens --agent codex
Same command for any agent — swap --agent for claude-code, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Product Lens — Think Before You Build This lane owns product diagnosis, not implementation-ready specification writing. If the user needs a durable PRD-to-SRS or capability-contract artifact, hand off to `product-capability`. ## 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 product brief before engineering planning starts ## 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. If the result is "yes, build this," the n

What does the product-lens skill do?
Use this skill to validate the "why" before building, run product diagnostics, and pressure-test product direction before the request becomes an implementation contract.
How do I install it?
Run `npx skills add mturac/everything-openai-codex --skill product-lens --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From mturac/everything-openai-codex, a repository with 84 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
