code-investigate
Dual-perspective code investigation. Claude explores independently, then Codex explores independently (no feeding), finally integrate both conclusions.
npx skills add majiayu000/claude-skill-registry --skill code-investigate --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.
# Code Investigate Skill ## Trigger - Keywords: investigate code, how feature works, trace implementation, dual confirmation, deep dive, how code works, what this code does, code research ## When NOT to Use - Just need quick lookup (use Grep/Glob directly) - Code review (use codex-review) - System verification (use feature-verify) - Git history tracking (use git-investigate) ## Core Principle ``` Codex must explore independently. Feeding Claude's conclusions to Codex is prohibited. ``` ``` ┌─────────────────┐ ┌─────────────────┐ │ Claude Explores │ │ Codex Explores │ │ Independently │ │ Independently │ │ (Phase 1-2) │ │ (Phase 3) │ └────────┬────────┘ └────────┬────────┘ │ │ ▼ ▼ ┌───────────┐ ┌───────────┐ │ Claude │ │ Codex │ │ Conclusion│ │ Conclusion│ └─────┬─────┘ └─────┬─────┘ │ │ └───────────┬───────────┘ ▼ ┌─────────────┐ │ Consolidated│ │ Report │ │ (Phase 4) │ └─────────────┘ ``` ## Workflow | Phase | Name | Action | Output | | ----- | --------------- | ----------------------------------- | --------------------------- | | 1 | Claude Explore | Grep/Glob/Read to search code | Related files list | | 2 | Claude Conclude | Analyze logic, form understanding | Initial conclusion

What does the code-investigate skill do?
Dual-perspective code investigation. Claude explores independently, then Codex explores independently (no feeding), finally integrate both conclusions.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill code-investigate --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.
