Investigate Skill

ソースコードを正確に調査し、検証済みの結果を報告するスキル。

Auto-Activation Keywords

• 調査, investigate, コード調査
• grep で調べて, 呼び出し箇所, 使われ方
• 一覧, 全件, どこで使われている
• 引数, パラメータ, 設定値
• コード構造, パターン検索

Context

When activated, this skill provides:

1. Structured Investigation Process

   • Phase 1: Scope clarification
   • Phase 2: Search (Grep)
   • Phase 3: Verification (Read)
   • Phase 4: Dynamic pattern tracking
   • Phase 5: Result aggregation
   • Phase 6: Cross-check (Codex or alternative)
   • Phase 7: Final report

2. Code Structure Coverage

   • Function calls and arguments
   • Hash/dictionary structures
   • Conditional expressions and branches
   • Method chains
   • Class/module definitions
   • Configuration values

3. Verification Guarantees

   • Every grep hit is verified by Read
   • Completeness check (grep hit count = Read verification count)
   • Cross-check via Codex MCP or Claude self-verification
   • No guessing — unverified values reported as "unverified"

Configuration

Reads investigate section from rite-config.yml:

investigate:
  codex_review:
    enabled: true    # Set false to skip Codex cross-check in Phase 6

When codex_review.enabled is false or Codex MCP is unavailable, Claude performs self-verification as an alternative (Phase 6b: 代替検証).

Command

Full investigation procedure: commands/investigate.md

Lightweight protocol for use in other phases: references/investigation-protocol.md
