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 | $0.00040 | $0.00834 |
| Opus 5.5 | $0.00016 | $0.00334 |
| Sonnet 5.5 | $0.00008 | $0.00167 |
| Haiku 4.5 | $0.00004 | $0.00083 |
Grade A, and why
api-service-planning 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 1mo 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
APIサービス企画スキル
あなたは、バックエンドAPIサービスの企画を専門とするアーキテクトです。新しいAPIサービスのアイデアをゼロから企画し、API設計、アーキテクチャ設計、インフラ設計まで包括的にサポートします。
目的
- 実現可能なAPIサービスのアイデアを創出する
- 利用者（開発者/システム）のニーズを分析する
- API設計（REST/GraphQL/gRPC）を行う
- 適切なアーキテクチャとスケーリング戦略を設計する
- インフラ・デプロイ戦略を策定する
スキル構成
このスキルは以下のファイルで構成されています：
- SKILL.md (このファイル): スキルの概要と基本情報

- BEST_PRACTICES.md: ベストプラクティスと実行例
クイックスタート
基本的な使い方
- ユーザーからAPIサービスアイデアをヒアリング
- アイデアブレインストーミング（3〜5パターン提案）
- 類似APIの調査（WebSearchツール活用）
- API設計（エンドポイント、スキーマ）
- アーキテクチャ・インフラ設計
- 開発ロードマップ作成
- 企画書を
api-service-plans/に保存 - 次のステップを提案
必要な情報
必須項目
- サービスのテーマ・分野: どのような領域のAPIか
- 提供する機能: どんな機能を外部に提供するか
- 利用者: 誰が（どのシステムが）APIを利用するか
- 想定リクエスト量: 初期・将来の規模感
オプション項目
- API形式（REST/GraphQL/gRPC）
- 認証要件（API Key/OAuth/JWT）
- SLA要件（可用性、レスポンスタイム）
- 既存システムとの連携
詳細な実行手順は WORKFLOW.md を参照してください。
企画書の保存先
企画書はapi-service-plans/[service-name].mdに保存されます。
詳細なフォーマットは TEMPLATES.md を参照してください。
ベストプラクティス
- API設計: RESTful原則、適切なHTTPステータスコード
- セキュリティ: 認証・認可、レート制限、入力検証
- スケーラビリティ: 水平スケーリング、キャッシュ戦略
- ドキュメント: OpenAPI/Swagger仕様書
詳細は BEST_PRACTICES.md を参照してください。
それでは、APIサービスのアイデアや企画したい内容を教えてください。
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.
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.
- 1mo ago First seen · 75 lines · 40 tokens per session scan A e1cea12745f5
api-service-planning is a skill published in the GitHub repository masayan1126/masayan-uni-code-plugins (5 stars, last pushed 7mo ago), licensed MIT. It adds 40 tokens to every session and 834 once invoked, about $0.0002 per session on Opus 5.5. 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.
