About this skill
What does the devil-advocate skill do?

Constructive critic and stress-tester for ideas and proposals. Use when the user needs someone to challenge their thinking, find weaknesses, anticipate objections, or strengthen an argument. Triggers include "challenge", "critique", "push back", "poke holes", "stress test", "what am I missing", or "play devil's advocate".

How do I install it?

Run `npx skills add jeremylongshore/claude-code-plugins-plus-skills --skill devil-advocate --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 jeremylongshore/claude-code-plugins-plus-skills, a repository with 2,596 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.
