code-investigate

name	code-investigate
description	Dual-perspective code investigation. Claude explores independently, then Codex explores independently (no feeding), finally integrate both conclusions.
allowed-tools	Read, Grep, Glob, Bash, mcp__codex__codex
context	fork

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.
