dev-run

An orchestration skill that runs a planned range of development tasks through implementation, checking, and debugging. It uses separate helper agents and tracks task dependencies.

In plain words
What is it for?
Use it to automatically execute a numbered range of tasks from an existing development plan, such as tasks 001 through 005.
Why use it?
It removes the need to run each planned task and its follow-up checks manually.

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

dev-run 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 2d ago.

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.

Dev Run

Plan 内の指定範囲タスクに対し、impl → verify → debug のループを自動実行するオーケストレーションスキル。各タスクを Task サブエージェントに委託し、TaskCreate/TaskUpdate で依存関係付きの進捗管理を行う。

前提知識

dev-* スキルフロー内の位置

dev-context → dev-plan → [dev-run] → (完了)
                            ├─ impl サブエージェント (×タスク数)
                            ├─ debug サブエージェント (エラー時)
                            └─ verify サブエージェント (全タスク完了後)

引数フォーマット

/dev-run <plan-name> <from-task-id> <to-task-id>
  • plan-name: 既存の Plan 名(docs/dev/plans/<plan-name>/ が存在すること)
  • from-task-id: 開始タスク ID(例: "001")
  • to-task-id: 終了タスク ID(例: "005")

サブエージェント制約(重要)

サブエージェントは Task ツールを使用できない(ネスト不可のアーキテクチャ制約)。そのため:

  • コード探索は Glob/Grep/Read を直接使用する
  • TodoWrite は使用しない(TaskCreate/TaskUpdate で進捗管理する)
  • プロンプトに context.md を埋め込み、サブエージェントのファイル読み込みを最小化する

ワークフロー

Step 1: 事前検証とコンテキスト読み込み

  1. docs/dev/context.md の存在を確認する。存在しない場合は /dev-context の実行を案内して終了する
  2. docs/dev/plans/<plan-name>/ の存在を確認する。存在しない場合は /dev-plan の実行を案内して終了する
  3. docs/dev/context.md を Read で読み込み、以下を抽出する:
    • テスト実行コマンド(Test Framework セクション)
    • ビルドコマンド(Build & Run セクション、あれば)
    • Lint コマンド(Build & Run セクション、あれば)
    • カバレッジ閾値(Test Framework セクションの Coverage Threshold)
  4. docs/dev/plans/<plan-name>/plan.md を Read で読み込む
  5. 指定範囲(from-task-id 〜 to-task-id)の全タスクファイルを Glob + Read で読み込む
  6. 各タスクの status, dependencies, estimated_complexity を確認する
範囲外依存チェック

タスクファイルの dependencies に、指定範囲外のタスク ID が含まれる場合:

  • そのタスクファイルを Read し、status を確認する
  • status: done → 問題なし
  • それ以外 → AskUserQuestion でユーザーに警告し、続行/中断を確認する

Step 2: TaskCreate で依存関係グラフ構築

2a. タスクの登録

指定範囲内で statusdone でないタスクごとに TaskCreate を実行する:

TaskCreate:
  subject: "impl-NNN: <タスクタイトル>"
  description: "Plan <plan-name> のタスク NNN を TDD 実装する"
  activeForm: "Implementing task NNN: <タスクタイトル>"
2b. 依存関係の設定

タスクファイルの dependencies を TaskUpdate の addBlockedBy にマッピングする。

ID マッピングテーブルを構築: {"001": "<TaskCreate_ID>", "002": "<TaskCreate_ID>", ...}

  • 範囲内の依存: 対応する TaskCreate ID を blockedBy に設定
  • 範囲外の依存(done 済み): blockedBy から除外
  • status: done のタスク: TaskCreate しない、依存元からも除外

What ships with it

3 files 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.

Changes

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.

dev-run is a skill published in the GitHub repository classmethod/tsumiki (974 stars, last pushed 25d ago), licensed MIT. It adds 105 tokens to every session and 3,454 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
