Instructions

  1. Preflight:

    • ドキュメント精査原則(Preflight必須):変更前に必ず以下を実施すること。
      • 現在のCLAUDE.md/AGENTS.mdを全て読み込む。
      • 変更依頼の背景・理由・期待される効果を確認する。
      • 影響を受けるSkills/Subagentsを特定する。
      • これらを完了するまで変更を開始しない。
    • 変更対象(section=コア原則/成果物タイプ/品質ゴール/WF索引/パス辞書等)、変更範囲、理由を確認する(推測しない)。
    • ./assets/claude_md_structure.md を参照し、CLAUDE.mdの構造を把握する(テンプレートファースト)。
  2. 変更種別の判断:

    • 以下の変更種別を特定し、それぞれの手順に従う:
      • Section 1-5 変更: コア原則/成果物タイプ/品質ゴール/Skill選択ポリシー/成果物分類
      • Section 6 変更: ワークフロー索引(WF連携マップ)
      • Section 7 変更: パス辞書(root/dirs/patterns/meta)
      • 複合変更: 複数セクションにまたがる変更
  3. 生成(変更実施):

    • ./questions/core_rule_maintenance_questions.md に従い入力を確定する。
    • 既存の構造・フォーマットを崩さない(最小差分で修正)。
    • CLAUDE.mdの必須セクション区切りを維持する。
    • 変更内容:
      • WF索引変更時: 該当フェーズに追記/修正、矢印(→)で連携を表現
      • パス辞書変更時: dirs/patterns/metaの適切な箇所に追記、変数参照の整合性を確認
      • コア原則変更時: 全Skillsへの影響を確認し、必要なら各SKILL.mdとtriggersも更新する
      • Skill運用ルール変更時: 「Skillは原則必須」「どうしてもskillsに該当がない場合のみ省略可」「Skill完了後はtriggersで次へ必ず進む」などの運用原則は、必ずCLAUDE.mdの ## 1. コア原則 に記載する(Section 4だけに置かない)
  4. 整合性チェック:

    • パス辞書変更時:
      • 変数参照({{patterns.xxx}}等)が正しく解決されることを確認
      • 循環参照がないことを確認
      • 実際のファイルパスとして有効であることを確認
    • WF索引変更時:
      • 参照先Skillが存在することを確認
      • 連携フロー(→)の整合性を確認
      • 各SkillのNext Action triggersと整合していることを確認
  5. 3環境同期(Skills/Assets統一):

    • CLAUDE.md変更後は python3 scripts/update_agent_master.py --source claude --force で同期を実施する(Claude起点)。
    • 同期内容: CLAUDE.mdからAGENTS.md等の派生ルールを再生成し、.claude/skills / .claude/commands を各環境へ同期する(SKILL.md だけでなく assets/ questions/ evaluation/ triggers/ scripts/ も含めて統一する)。
    • 備考: .cursor/.codex/.opencode/.github 側のskillsを直接編集しない(起点で変更→同期で統一)。AGENTS.mdは生成対象だが、Cursor専用の運用ファイルとして扱う(手動で直接編集しない)。
  6. QC(必須):

    • ./evaluation/evaluation_criteria.md を参照し、以下を自己評価する:
      • 必須セクション維持
      • パス辞書の変数参照整合性
      • WF索引とSkillsのNext Action triggers整合性
      • 3環境同期の実施
    • 評価結果を成果物末尾に追記する(修正有無/理由)。
    • 重大な問題がある場合は修正し、再評価する(最大3回)。
  7. バックログ反映:

    • 次アクション(影響Skillsの更新、レビュー依頼等)を抽出しバックログへ反映する。
    • 反映先・編集制約・差分提示は AGENTS.md / CLAUDE.md の全体ルールに従う。

subagent_policy:

  • 単なる評価目的のqa-xxxサブエージェントはAgents/に作成しない
  • 評価は ./evaluation/evaluation_criteria.md を参照したインライン評価を基本とする
  • ただし変更が広範/高リスク、またはユーザー要望がある場合は qa-skill-qc / red-team-feedback-loop 等の既存Subagentを並列実行してレビュー強度を上げてもよい(新規Agent作成はしない)
