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 | $0.00778 | $0.00778 |
| Opus 5 | $0.00389 | $0.00389 |
| Sonnet 5 | $0.00156 | $0.00156 |
| Haiku 4.5 | $0.00078 | $0.00078 |
Grade A, and why
atx-mcp CLAUDE.md 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 7d 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
atx-mcp 開発規約
このファイル自体の規律
本リポジトリは public。CLAUDE.md を含む全ファイルには「公開してよい情報」しか書かない:
個人情報・メールアドレス・ローカルの絶対パス(/Users/... 等)・他プロジェクト名・トークン/秘密情報・
社内事情は書き込み禁止。記録が必要な非公開情報はリポジトリ外に置く。
テスト素材の規律
- リポジトリに入れてよいテスト画像は完全合成のもののみ
(
cargo run -p atx-core --example gen_fixtureで決定論的に再生成できること) - ユーザーから渡された実写真・第三者素材は、ローカルでの動作確認に使ってよいが コミットしてはならない(EXIF 除去済みでも不可。渡されたのは検証目的であり公開許諾ではない)
- フィクスチャは EXIF レスを正とし、
has_gpsの否定をテストで固定する
言語の層構造(厳守)
- 開発対話・設計議論・コミットメッセージ・docs/(DESIGN.md, ROADMAP.md 等)・コードコメント: 日本語
- MCP ツール層(ツール名・説明・サーバ instructions・エラーメッセージ・警告・structuredContent フィールド名): 英語 (LLM が読む面。精度・トークン効率・MCP エコシステム慣習のため。変更しない)
- README: README.md = 英語(主)、README.ja.md = 日本語、README.zh-CN.md = 簡体中文。 利用者向け内容の変更時は3ファイル同時更新
体制
- Fable が司令塔(全体設計・サブエージェント統制・最終確認)。調査・実装は Opus / Sonnet にモデル適性で委譲
- 不具合修正は必ず「失敗するテストで再現 → 修正 → 通過確認」の順
- PBT(proptest)が有効な性質は積極的にテスト化する
設計の正
- 設計判断は docs/DESIGN.md(§9 に実装時差分)、方向性は docs/ROADMAP.md を正とする
- 決定論(同一入力+同一レシピ→バイト同一出力)と原本不変はいかなる変更でも壊さない
- レシピ canonical hash を変える変更は禁止(新フィールドは serde skip_serializing_if でデフォルト省略)。 やむを得ない場合は DSL バージョンで世代分離
- MCP ツールは増やさない(作業動詞のみ)。許される追加は検出系・検証系・語彙参照系のみ (docs/ROADMAP.md「Agent UX の規律」参照)
リリース
- RELEASING.md 参照。git commit / push / タグ発火はユーザーの明示指示があるときのみ
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.

atx-mcp CLAUDE.md is an instructions file published in the GitHub repository gridhra/atx-mcp (0 stars, last pushed today), licensed MIT. It adds 778 tokens to every session, about $0.0039 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.
