Same command for any agent — swap --agent for codex, cursor, copilot.

What does the error-analysis skill do?
This skill should be used when analyzing errors, stack traces, and logs to identify root causes and implement fixes.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill error-analysis-jayteealao-aperture --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.
