po-check-spec

po-check-spec is a skill for Claude Code, Codex from elvezjp/ixv-agents. It costs 78 tokens per session (1,134 once invoked), scanned A, original, MIT.

A check of a project's README.md specification to see whether a user's request is already covered.

In plain words
What is it for?
It reviews goals, scope, requirements, acceptance conditions, and the task backlog, then reports whether the request is covered or needs a specification update.
Why use it?
It prevents work from starting before confirming that the request belongs in the agreed project plan.

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

po-check-spec 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 11d 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.

What it actually says

PO Spec Check

README.md(仕様書)を確認し、ユーザーの要望が反映済みか判定する。

When to Use

  • ユーザーが新しい要望を伝えた時
  • 「仕様確認」「要望の反映確認」と言われた時
  • ワークフロー フェーズ2(企画・要件定義フェーズ)の分岐判定時

Instructions

Step 1: 要望内容を確認

ユーザーの要望内容を明確にする。 不明確な場合は以下を質問:

項目 質問例
何を実現したいか 「具体的にどのような動作を期待しますか?」
完了の定義 「どうなったらOKですか?」

Step 2: README.mdを読み取り

README.md を読み取り、以下のセクションを確認:

  • ## Goal - 目的
  • ## Scope - 範囲
  • ## Requirements - 機能要件
  • ## Acceptance Criteria - 受入条件
  • ## Backlog - バックログ

Step 3: 反映状況を判定

要望が以下のいずれかに該当するか確認:

反映済みの判定基準:

  1. Requirements に該当する要件が記載されている
  2. Backlog に関連するエントリがある(Status: ready/in_sprint)
  3. Goal/Scope に包含されている

未反映の判定基準:

  1. Requirements に該当する要件がない
  2. Backlog に関連エントリがない
  3. Scope の Non-Goals に該当する

Step 4: 結果を報告

反映済みの場合:

仕様確認完了: 要望は仕様に反映済みです。

該当箇所:
- Requirements: {該当する要件}
- Backlog: {関連エントリ}

→ 次のステップ: フェーズ3 設計計画へ進んでください。

未反映の場合:

仕様確認完了: 要望は仕様に未反映です。

要望内容: {要望の要約}

→ 次のステップ:
  1. po-request-yaml スキル(task_type: spec_update)で仕様策定タスクを発行してください
  2. SMが README.md を更新した後、Human承認を得てください

Non-Goalsに該当する場合:

仕様確認完了: 要望は Non-Goals に該当します。

Non-Goals:
- {該当するNon-Goals項目}

→ 次のステップ:
  1. ユーザーに Non-Goals の理由を説明してください
  2. 必要に応じて Scope の変更を検討してください

Examples

Example 1: 反映済みの場合

要望: 「ユーザー認証機能が欲しい」

README.md の内容:

## Requirements
- ユーザー認証(ログイン/ログアウト)
- セッション管理

報告:

仕様確認完了: 要望は仕様に反映済みです。

該当箇所:
- Requirements: ユーザー認証(ログイン/ログアウト)

→ 次のステップ: フェーズ3 設計計画へ進んでください。

Example 2: 未反映の場合

要望: 「ダークモード対応したい」

README.md の内容: ダークモードに関する記載なし

報告:

仕様確認完了: 要望は仕様に未反映です。

要望内容: ダークモード対応

→ 次のステップ:
  1. po-request-yaml スキル(task_type: spec_update)で仕様策定タスクを発行してください
  2. SMが README.md を更新した後、Human承認を得てください

References

詳細なチェックリストは references/spec-checklist.md を参照。

Notes

  • このスキルはPOロールのみが使用する
  • README.md は唯一の仕様書(Single Source of Truth)
  • 仕様の変更はHumanの最終承認が必要
Files

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.

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.
