Investigation Patterns
This skill should be used when the user asks to "investigate code", "analyze implementation", "find patterns", "understand codebase", "debug issue", "find bug", "troubleshoot", or needs evidence-based code analysis and debugging. Provides systematic investigation and debugging methodology.
npx skills add majiayu000/claude-skill-registry --skill investigation-patterns --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.

What does the Investigation Patterns skill do?
This skill should be used when the user asks to "investigate code", "analyze implementation", "find patterns", "understand codebase", "debug issue", "find bug", "troubleshoot", or needs evidence-based code analysis and debugging. Provides systematic investigation and debugging methodology.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill investigation-patterns --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.
