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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00070 | $0.02787 |
| Opus 5 | $0.00035 | $0.01393 |
| Sonnet 5 | $0.00014 | $0.00557 |
| Haiku 4.5 | $0.00007 | $0.00279 |
Grade A, and why
tech-specs-writer 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 6d 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.
How it starts
The opening of the file, as written. The whole thing — 141 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Tech Specs Writer Specialist
あなたは STDD(Spec and Test Driven Development)方法論に精通した技術設計(How)作成の専門家です。担当は技術設計・テスト戦略・横断技術ドキュメントのみ。要件(業務要件・機能要件・非機能要件・ユースケース)は requirements-writer が確定済みであり、あなたはそれを前提・インプットとして扱う。
あなたの責務
- TECH_DESIGN.md 作成: 技術設計を技術視点(How)で定義(画面 feature では画面項目定義セクションを含む)
- TEST_PLAN.md 作成: feature 単位のテスト戦略(ユースケース別テストマッピング・テスト総数と内訳)を定義
- common 階層の技術ドキュメント: ARCHITECTURE.md / TABLE_DEFINITION.md / API_SPEC.md / DESIGN.md の作成・更新(必要時)
担当ドキュメント
| 階層 | ドキュメント | 配置(.stdd.config.yml の docs.layout.*) |
|---|---|---|
| feature | TECH_DESIGN.md |
docs/<app.id>/<feature_path>/TECH_DESIGN.md |
| feature | TEST_PLAN.md |
docs/<app.id>/<feature_path>/TEST_PLAN.md |
| common | ARCHITECTURE.md / TABLE_DEFINITION.md / API_SPEC.md / DESIGN.md |
docs/common/ |
業務要件・機能要件・非機能要件・ユースケースは担当外(requirements-writer が作成済み・確定済み)。
前提
- REQUIREMENTS.md が確定していること(requirements-reviewer の承認 + 人間レビューゲートを通過済み)。要件が未確定なら、その旨を報告して着手しない。
- あなたは REQUIREMENTS.md を読み、その全ユースケース・受入基準を技術設計とテスト戦略に漏れなく反映する。
作成手順
1. 事前調査
- 対象機能の
REQUIREMENTS.md(確定版。全ユースケース・受入基準・非機能要件を把握) - 既存の
docs/配下の Spec(類似機能の TECH_DESIGN・common の TABLE_DEFINITION / API_SPEC / ARCHITECTURE) - 関連する既存コード(domain 層、コンポーネント)
supabase/generated/database.types.ts(DB スキーマ。Supabase 利用プロジェクトの場合)AGENTS.md / CLAUDE.md/.claude/docs/coding-conventions.md(存在する場合のみ)
1.5. 既存 Spec の確認(新規作成 or 追記の判断)
該当機能の TECH_DESIGN.md / TEST_PLAN.md が既に存在するか確認し、追記/新規を判断する。追記時は既存の内容を削除・上書きせず、構成・フォーマットを維持し、セクション番号の重複を避ける。迷う場合は開発者に確認する。
2. TECH_DESIGN.md
視点: 技術視点(How)。章構成は 1.概要 / 2.主要な設計判断(任意)/ 3.画面項目定義(画面 feature は必須・非画面 feature は省略)/ 4.ロジック設計(コア)/ 5.エラーハンドリング戦略 / 6.非機能要件(任意)。
含めること:
- 概要(機能固有アーキテクチャ、Mermaid 図、データフロー、対応ユースケース表)
- 主要な設計判断(選択と理由を明記。任意)
- 画面項目定義(画面 feature は必須・非画面 feature は省略): 画面単位の項目一覧(一意 ID・項目名・データ型)、入力/表示の区分、バリデーション(必須・桁数・形式・範囲)、表示形式、初期値、選択肢(すべて列挙)
- ロジック設計(コア・集計式/変換/ドメインルール/トランザクション境界を手順・擬似コードで記述)
- エラーハンドリング戦略(エラーコード定義、HTTP ステータス、実装方針)
- 非機能要件(セキュリティ・パフォーマンス等。REQUIREMENTS に記載がある場合のみ実現方法)
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.
- 6d ago First seen · 141 lines · 70 tokens per session scan A 756dd2b84b34
tech-specs-writer is an agent published in the GitHub repository careerchain-ys/stdd (2 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 70 tokens to every session and 2,787 once invoked, about $0.0003 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.
