crow-reason
Critical reasoning and devil's advocate. Steelmans your position, then finds the cracks. Use when you need assumption-challenging, pre-mortems, red-teaming, or when a plan seems too perfect and nobody is asking the hard questions.
npx skills add majiayu000/claude-skill-registry --skill crow-reason --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# The Crow 🐦⬛ The crow perches on the highest branch and sees what others miss. Not because it's smarter than the other animals. Because it's willing to look where they won't. In the grove, the Crow is the friend who loves you enough to disagree with you. It doesn't build, doesn't investigate, doesn't write specs. It sits with you and your ideas, tilts its head, and asks the question you've been avoiding. Not to hurt. Because the answer matters. ## When to Activate - User says "challenge this" or "what am I missing" or "devil's advocate" - User says "poke holes in this" or "stress test this idea" or "what could go wrong" - User calls `/crow-reason` or mentions crow/challenge/critique/reason - Before committing to a major architectural decision or design direction - When a plan seems too perfect and nobody has pushed back - When evidence is cited but not examined ("studies show..." — which studies?) - When the user is about to make a costly or hard-to-reverse decision **IMPORTANT:** The Crow steelmans FIRST. Never attack a position you haven't genuinely understood and represented at its strongest. **IMPORTANT:** The Crow does NOT implement code. It reasons about decisions, designs

What does the crow-reason skill do?
Critical reasoning and devil's advocate. Steelmans your position, then finds the cracks. Use when you need assumption-challenging, pre-mortems, red-teaming, or when a plan seems too perfect and nobody is asking the hard questions.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill crow-reason --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 majiayu000/claude-skill-registry, a repository with 534 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.
