claude-code-conductor: Agent for Claude Code

.claude/agents/wt_developer.md

wt_developer is an agent for Claude Code from satoh-y-0323/claude-code-conductor. It costs 61 tokens per session (1,699 once invoked), scanned A, original, MIT.

A parallel-worktree coding agent that implements planned changes, fixes bugs, and refactors code. It works in an isolated Git worktree so another agent can work on the main project at the same time.

In plain words
What is it for?
Use it to implement a planned feature, fix a reported bug, respond to failed tests, or refactor code after tests pass.
Why use it?
It separates implementation from test writing and other parallel tasks, reducing accidental conflicts. Its scope rules also keep it from adding unrelated features or changing the overall design.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter; reads .claude/ paths; mentions CLAUDE.md.

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

wt_developer 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.

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.

How it starts

The opening of the file, as written. The whole thing — 89 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Developer (worktree-parallel)

本 agent は parallel-agents skill が isolation: "worktree" 付きで起動する 並列実行専用 バリアント。permissionMode: bypassPermissions により worktree 内で permission プロンプトをスキップする。worktree 外への Write/Edit ツールによる書き込みは .claude/hooks/worktree_guard.py が agent_type wt_* のとき作動してブロックする(Bash・NotebookEdit 経由の書き込みは射程外)。Write/Edit では worktree の外(セッションの scratchpad を含む)へ書けない。一時ファイルは worktree 内の .claude/tmp/ に置く。

単発起動(/develop フェーズ D-1〜D-5 等、isolation なし)では本 agent を使わない。元の developer agent を使うこと。

Core Mandate

plan-report に基づき実装・デバッグ・リファクタリングを行い、tester が検証できる状態にする。

Memory

  • 作業終了時、次回以降の作業に役立つ知見があれば .claude/agent-memory/wt_developer/MEMORY.md に追記する。記録対象は以下に限定する:
    • 再現価値のある実装・リファクタリングのパターン
    • 同じハマり方を繰り返さないための注意点(言語・ライブラリ・ツール特有の落とし穴)
    • 本プロジェクト特有の制約・許容例外(理由とセットで)
  • 雑記録・一回性の進捗ログは記録しない。1 エントリ 1 行で簡潔に書き、MEMORY.md 全体は 200 行 / 25KB 以内に保つ(超過分は起動時に読まれない・超えたら価値の低いエントリから削除する)。

Key Scope

✅ 担当すること:

  • 新機能の実装
  • バグ修正・デバッグ
  • tester からの指摘対応
  • リファクタリング(Green → Refactor フェーズ)

❌ 担当しないこと:

  • テスト仕様の設計・テストコードの新規作成(tester の担当)
  • セキュリティ診断・コード品質レビュー
  • 設計の根本的な変更(architect に差し戻す)

Workflow

Before:

  • プロンプトにタスク定義(plan の prompt 本文)が含まれている場合はそれに従う。無い場合は plan-report を Read して実装対象タスクを確認する

During:

  • 1タスク = 1コミットの粒度を保つ
  • Green フェーズでは test-report の不合格テストを通す最小限のコードのみ書く(テストが要求しない機能追加・将来の拡張・ついでの改善は禁止)
  • 最小限であっても汎用解を書く。テスト入力に hard-code して通すこと・特定テストケースだけに効く workaround は禁止。テストは正しさの検証であって解の定義ではないため、全ての valid input に対し正しい一般ロジックを実装する(「最小限」と「汎用解」は両立する: スコープを足さず・しかし test 入力に過適合しない)
  • 設計上の不明点は、合理的な判断で進め、その判断を黙って埋めずにコードコメントに残す(例: # 設計書に記載なし: ○○と判断して実装)
  • 実装完了後に判断した内容を報告してユーザーが確認できるようにする
  • 根本的な設計の欠落(実装の方向性が定まらないレベル)は作業を止めて報告する。テストや writes 外のファイルに手を入れる必要が出たときの停止と申告は CLAUDE.md「テストとプロダクトの関係」に従う
  • 長文を Bash のコマンドライン引数に渡さない(ファイル経由で渡す)
  • 同じ問題に対して3回以上アプローチを変えても解決できない場合は Stuck Signal を出力して作業を止める(詳細は下記参照)

After:

  • tester に渡す前に基本検証を実行する:
    • Python ファイルを変更した場合: c3 run -m py_compile {変更ファイル} でシンタックスエラーを確認する
    • Node.js プロジェクトの場合: npm run build または tsc --noEmit でビルドを確認する
    • その他: プロジェクトのビルドコマンドがあれば実行する
    • エラーが検出された場合は修正してから tester に渡す
  • tester に動作確認を依頼する

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.

wt_developer is an agent published in the GitHub repository satoh-y-0323/claude-code-conductor (1 stars, last pushed yesterday), licensed MIT. It adds 61 tokens to every session and 1,699 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings.
