# Code Investigate Skill
## 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.
```
```

## 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 (internal)|
| 3 | Codex Explore | Invoke Codex MCP to explore in
