claude-code-conductor: Skill for Claude Code

.claude/skills/start/SKILL.md

start is a skill for Claude Code from satoh-y-0323/claude-code-conductor. It costs 53 tokens per session (2,555 once invoked), scanned A, original, MIT.

A workflow entry point that guides a development session into planning, implementation, debugging, or review. It includes a session check and routes work through defined steps, including test-driven development (TDD), where tests are written before the code they check.

In plain words
What is it for?
Use it to start a standard feature workflow, a debugging workflow, or a review cycle. It helps move work between requirements, design, planning, implementation, testing, and review.
Why use it?
It gives a consistent starting path instead of leaving developers to decide which process to follow. It also restores or initializes session state before the workflow begins.

Skill for Claude Code

Written for Claude Code: installed under .claude/. Also seen: reads .claude/ paths; names the AskUserQuestion tool.

This is satoh-y-0323/claude-code-conductor's own configuration. It tells Claude Code how to work on claude-code-conductor itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything claude-code-conductor configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

start scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/archive_reports.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

start

開発ワークフローの入口。フロー順序: セッション初期化ガード(最優先)→ Step 0(レポート整理)→ Step 1(開始地点選択)→ Step 2(フェーズ遷移)

ワークフローは 2 つだけ:

  • 標準ワークフロー: ヒアリング → 設計 → 計画 → 実装(TDD) → レビュー → 指摘ありで計画へ戻る、なしで終了
  • デバッグワークフロー: systematic-debugger → 実装(developer + tester Green) → レビュー → 指摘ありで標準ワークフローの計画へ、なしで終了

その他の単発タスク(ドキュメント作成など)は対応する個別コマンド(例: /doc)を直接使う。


最優先: セッション初期化ガード(Step 0 より前に必ず実行)

本体(Step 0 以降)に入る前に、当該セッションで /init-session が実行済みかを判定し、未実行なら自動実行する。 Bash で判定する:

c3 run .claude/skills/init-session/scripts/session_guard.py check
  • INIT_DONE(フラグの中身が現在の CLAUDE_CODE_SESSION_ID と一致)→ 既に初期化済み。そのまま Step 0 へ進む。
  • INIT_NEEDED(不一致 / フラグ不在 / CLAUDE_CODE_SESSION_ID が空)→ Skill ツールで init-sessionfrom-start 引数付きで呼ぶ。
    • init-session が(必要なら /setup を連鎖実行し)前回状態を復元し、init_session.flag を書く。from-start 付きのため init-session 側は開始方法の選択(Step 4)や陳腐化タスク確認などの対話プロンプトをスキップして復元サマリのみ提示する。
    • init-session の Skill 実行が完了したら本スキルに戻り、続けて Step 0(レポート整理)以降を実行する。

ループ回避: init-session は本体開始直後に init_session.flag を現セッション ID で書く。そのため init-session(Step 5「ワークフローで始める」)が /start を呼び戻しても、本ガードは INIT_DONE と判定し再帰呼び出ししない。


Step 0: レポートの整理

Glob で .claude/reports/*.md を検索する(archive/ 配下は含まない)。 レポートが存在しない場合はこの Step をスキップして Step 1 へ進む。

レポートが存在する場合はファイル名の一覧をテキストで提示してから AskUserQuestion で確認する:

{
  "questions": [{
    "question": "既存のレポートがあります。どうしますか?",
    "options": [
      { "label": "全てアーカイブして新しく始める", "description": "全レポートを reports/archive/ に移動する" },
      { "label": "アーカイブするフェーズを選ぶ", "description": "フェーズ単位で選んで一部だけ移動する" },
      { "label": "そのまま引き継ぐ", "description": "レポートを変更せずに続ける" }
    ]
  }]
}

アーカイブは専用スクリプトが行う。このコマンドは、移動先に同名のファイルが既にある場合は 移動元を {元の名前}-archived-{元ファイルの更新時刻}.md へリネームして両方を残す(既存ファイルは 1 バイトも変更しない)。 アーカイブ先ディレクトリが無ければ作成する。移動できなかったファイルがあれば stderr に一覧を出して exit 1 になる。

「全てアーカイブして新しく始める」の場合: Bash ツールで実行する:

c3 run .claude/skills/start/scripts/archive_reports.py

「アーカイブするフェーズを選ぶ」の場合: AskUserQuestion で対象フェーズを確認する:

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
