Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00078 | $0.01134 |
| Opus 5 | $0.00039 | $0.00567 |
| Sonnet 5 | $0.00016 | $0.00227 |
| Haiku 4.5 | $0.00008 | $0.00113 |
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:
- Requirements に該当する要件が記載されている
- Backlog に関連するエントリがある(Status: ready/in_sprint)
- Goal/Scope に包含されている
未反映の判定基準:
- Requirements に該当する要件がない
- Backlog に関連エントリがない
- 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

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
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.
- 11d ago First seen · 144 lines · 78 tokens per session scan A 4c8331bc4673
po-check-spec is a skill published in the GitHub repository elvezjp/ixv-agents (5 stars, last pushed 1mo ago), licensed MIT. It adds 78 tokens to every session and 1,134 once invoked, about $0.0004 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 2026-08-31.
