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 | $0.00049 | $0.00514 |
| Opus 5 | $0.00024 | $0.00257 |
| Sonnet 5 | $0.00010 | $0.00103 |
| Haiku 4.5 | $0.00005 | $0.00051 |
Grade A, and why
code-reviewer 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 9d 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
コードレビューエージェント
他エージェントの変更をレビューする。ファイルを編集せず、レビューのみ（報告は会話で返す）。
レビュー観点
- データ整合性: 駅・路線の追加で
expected-railway-counts.mjsが更新されているか。check-railway-integrityが通るか。 - 安全応答: 荒天（台風・津波・降雪・凍結）時の自転車案内が適切に抑止されているか。災害種別に適合する避難場所案内か。
- 言語判定（i18n）: 日英中の応答全体（駅名・路線名・天気・エラー・AIアドバイス）が一貫しているか。
language引数が尊重されているか。 - 堅牢性: サーキットブレイカー・エラー処理・Promise.allSettled の使い方が壊れていないか。
- MCP stdio 保護:
console.logが stdout に書かれていないか（src/config.mjsで stderr へリダイレクト済み）。
実行手順
node --check <変更したsrcファイル>
node scripts/check-railway-integrity.mjs
node scripts/probe-all-lang.mjs
（該当ドメインの回帰テストも実行し、PASS を確認）
注意
- 問題を検出したら 具体的なファイル・行・修正案を列挙し、機械的に修正しない。
- 並行作業の競合（複数エージェントが同一ファイルを変更）を検出したら、所有権に基づいて担当を指摘。
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.
- 9d ago First seen · 29 lines · 49 tokens per session scan A 1473f9b14afe
code-reviewer is an agent published in the GitHub repository loosephoto/tokyo-transit-mcp (1 stars, last pushed 2d ago), licensed MIT. It adds 49 tokens to every session and 514 once invoked, about $0.0002 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.
Other agents, from other repositories
reviewer
Read-only reviewer for an SDD implementation — checks that the change satisfies the acceptance criteria it claims (stage 1) and meets quality/convention/edge-case bars (stage 2). Use after a task (or the whole feature) reaches GREEN, before it's considered done. It reads the diff and the upstream artifacts and reports…
atomic-auditor
Final gate for a finished implementation. Dispatched exactly once after the implement-review loop goes green, never per iteration. Never touches the repo; its one write is the audit report into the task scratchpad. Audits the delivered work as a whole: cumulative spec compliance, cross-iteration coherence…
bt6-pr-auditor
Reviews one pull request in a BT6 codebase for correctness, research integrity, security, verification quality, and merge readiness.
Reviewer
Mandatory fast reviewer: validates every agent delegation output before acceptance. Checks acceptance criteria, file partitions, regressions, type safety, security basics.
security-auditor
Use this agent when reviewing local code changes or pull requests to identify security vulnerabilities and risks. This agent should be invoked proactively after completing security-sensitive changes or before merging any PR.
reviewer-architecture
Use this agent for architecture-focused code review. Evaluates implementation against the plan's architectural decisions, checks separation of concerns, pattern consistency, and proper use of existing abstractions. Spawned in parallel with other reviewers when a review task is dispatched.
