subagent-delegation-brief

subagent-delegation-brief is a skill for Claude Code, Codex from s977043/PlanGate. It costs 177 tokens per session (2,996 once invoked), scanned A, original, MIT.

A template for sending work to a subagent, meaning a separate coding agent working on an assigned task, and receiving a structured completion report.

In plain words
What is it for?
Use it to write delegation requests for research, implementation, review, or follow-up tasks, including the required outcome and verification status.
Why use it?
A subagent cannot see earlier conversation details, so missing instructions can lead to incomplete or incorrect work.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: mentions subagents; installed under .agents/ (shared by several agents); mentions Codex.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is sh scripts/check-outcome-contract.sh report.txt.

Good fit Use it to write delegation requests for research, implementation, review, or follow-up tasks, including the required outcome and verification status.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

subagent-delegation-brief 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 10d 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.

サブエージェントは会話履歴を持たない。書かれていない情報は「無い」ものとして扱われる。 このスキルは「何を書くか」のチェックリストであり、契約本文は持たない(正本を複製すると drift する)。

正本(定義はすべてここにある / 本ファイルで再定義しない)

正本 何が書いてあるか

参照解決順(導入先で必ずこの順に探す): 本 Skill が参照する docs/** は上流リポジトリ基準の相対パスであり、install.sh --claude / plugin(Claude marketplace)/ Codex の 3 経路とも配布対象外(解決不可)。(1) 導入先リポジトリの同名パスを探す → (2) 見つからなければ 「正本 <path> を参照できなかった」と明示し、本 Skill 内の記述を代替正本として扱い、推測で内容を補わない。plugin root 配下の探索は docs/** には適用しない: plugin が配布するのは agents / commands / skills / rules 等の定義ディレクトリのみで docs/ を配布対象として認識せず、plugin root 配下に相当する配布物が存在しないため、plugin root 段を置いても必ず空振りする(クラス A の rules 参照が plugin root 配下で解決できるのは rules/ が実際に配布されるからであり、この非対称を docs/** に持ち込まない)。

1. 派遣前チェックリスト(8 要素)

各行を埋めてから送る。埋められないものは「該当なし」と明示する(空欄は暗黙の許可・暗黙の禁止として誤読される)。

# 要素 この委託で具体的に何を書くか
1 役割・プロジェクト・項目ID・タスク名 後から報告を突合できる識別子を含めたか
2 なぜこのモデルか 定型作業ではなく判断系である理由を 1 行
3 最初に読む SSOT 優先順に列挙し、1 つ目だけで着手できるか。リンク切れを送信前に確認したか
4 既知の事実・実測値・確定済み結論・却下済み仮説 §2 の追加規約に従う(最も落ちやすい
5 順序付きタスク 依存順の番号付き。並列可能な範囲を明示したか
6 制約 write 可否 / 対象パス / 触ってはいけないもの / 禁止操作 / ソフト上限。§4 の worktree 定型も参照
7 出力形式 §3 の追加規約に従う(2 番目に落ちやすい
8 行動規範 軽量版 / フル版のどちらかを明示。長時間・複数ファイル・真因調査はフル版

2. 要素 4 の追加規約 — 却下済み仮説と「反証を許可する一文」

要素 4 は 3 つを分けて書く。確定済みの事実だけを書いても足りない。

  1. 確定済みの事実・実測値: 数値・ファイルパス・exit code など、再調査させないための一次情報
  2. 却下済み仮説: 「これは試さない / 再提案しない」と、その理由(理由が無いと相手は蒸し返す)
  3. 反証を許可する一文(必須): 例 —「上記は実測済み。ただし疑わしければ反証してよい。却下済み仮説以外は、実測が示すなら反論すること」

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.
