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 | $0.02422 | $0.02422 |
| Opus 5.5 | $0.00969 | $0.00969 |
| Sonnet 5.5 | $0.00484 | $0.00484 |
| Haiku 4.5 | $0.00242 | $0.00242 |
Grade A, and why
houki-nta-mcp AGENTS.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 19d 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 — 67 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
エージェント(Claude Code / Cowork のセッション)がこのリポジトリで作業するときの目次です。手順の本文はここには書きません。
仕様の正本
- 意図の正本は
specs/current/です。Wiki・Discussions・README は正本にしません。 - 変更は
specs/changes/<yyyymmdd>-<slug>/に出し、人が承認するまで Coder を起動しません。 - 承認された差分は Spec Publisher が
specs/current/に取り込み、差分のフォルダーをspecs/releases/<実装を出したタグ>/<yyyymmdd>-<slug>/へ移します(git mv)。移すときに proposal.md の「状態」を取り込み済みにします。取り込みでは current の spec.md に承認を書き足しません(下の「承認の記録」)。 - Coder は
specs/current/の本文を書き換えません。実装から仕様へ戻したい発見は、新しいspecs/changes/に書きます。 - 受入テストの
describeには仕様 ID(例:SPEC-NTA-GET-TSUTATSU-001)を含めます。npx spec-ids check(@shuji-bonji/spec-ids)が仕様とテストの ID を突き合わせ、CI(spec-gate)で走ります。
仕様 ID
- 形式は
SPEC-<領域>-<機能>-<3 桁>です(例:SPEC-NTA-GET-TSUTATSU-001)。領域NTAはこのリポジトリを表します。機能はspecs/current/<dir>/spec.mdのディレクトリ名から接頭辞nta_を除いて大文字にし、_を-にしたものです(nta_get_tsutatsu→GET-TSUTATSU)。番号は機能ごとに 001 からの通し番号です。 - 機能ごとに数列を分けるので、並行するブランチが衝突するのは同じ機能の仕様を同時に足したときだけです。
spec-ids checkは、見出しの ID の機能がディレクトリ名と一致することも検査します。 - 一度使った番号はその機能の中で再利用しません。仕様を外すときは
specs/changes/のREMOVEDに書き、テストからも ID を外します。 - 新しい ID は
npx spec-ids next specs/current/<dir>/spec.md(またはディレクトリ名npx spec-ids next nta_get_qa)で取ります。その機能の見出しの最大番号 +1 です。複数なら--count 3。番号の予約はしないので、万一同じ番号が 2 つの見出しに現れたら、マージ時にspec-ids checkの重複検知で止まります。 - ID の形式(正規表現・機能の導き方・組み立て)は
@shuji-bonji/spec-idsが決めています。このリポジトリで決めるのはspecs/spec-ids.jsonの領域NTA、接頭辞nta_、テストの glob だけです。
PR の種類
仕様とコードを、同じリポジトリの別の資産として扱います。人が振る舞いを承認するのは仕様 PR だけです。実装 PR で問うのは「承認済みの文と、テストと、コードが同じか」で、振る舞いに何を許すかの判断は実装レビューへ戻しません。CI の pr-scope(npx spec-ids pr-scope。@shuji-bonji/spec-ids 0.4.0 以降)が、ブランチ名の接頭辞ごとに変えてよいパスを検査します。
| ブランチ | 種類 | 変えてよいもの | 変えないもの |
|---|---|---|---|
spec/<yyyymmdd>-<slug> |
仕様 PR | specs/changes/<id>/(proposal.md と差分の spec.md) |
src/、テスト、specs/current/(proposal.md の front matter が implementation: none のときだけ specs/current/ も書いてよい) |
spec-init/<tool> |
初版起こし | specs/current/<dir>/spec.md、テスト名に仕様 ID を足すこと |
テストの期待値と本文、実装 |
それ以外(fix/ feat/ docs/ など) |
実装 PR など | テスト、src/、版と CHANGELOG、specs/current/ への取り込み(最終コミット)、specs/changes/ から specs/releases/<tag>/ への移動 |
specs/changes/ の書き換え(未承認の意図の追加、承認済み差分の変更) |
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.

houki-nta-mcp AGENTS.md is an instructions file published in the GitHub repository shuji-bonji/houki-nta-mcp (2 stars, last pushed 19d ago), licensed MIT. It adds 2,422 tokens to every session, about $0.0097 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 2026-09-23.
