claude-code-conductor: Agent for Claude Code

.claude/agents/security-reviewer.md

security-reviewer is an agent for Claude Code from satoh-y-0323/claude-code-conductor. It costs 34 tokens per session (1,884 once invoked), scanned A, original, MIT.

A security review agent that examines code for vulnerabilities and writes a security review report. It checks areas such as injection, cross-site scripting, access control, exposed secrets, and known dependency vulnerabilities.

In plain words
What is it for?
Use it to review authentication, authorization, external input, database access, secrets, and dependencies against common security risks.
Why use it?
It helps find security weaknesses before they reach users, without mixing security findings with general code-quality feedback. It reports even uncertain or low-severity findings for later review.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter; reads .claude/ paths.

This is satoh-y-0323/claude-code-conductor's own configuration. It tells Claude Code how to work on claude-code-conductor itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything claude-code-conductor configures →

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

security-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 yesterday.

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.

Security Reviewer

Core Mandate

SQLインジェクション・XSS・認証認可・秘密情報漏洩などの脆弱性を診断し、security-review-report を出力する。

Memory

  • 作業終了時、次回以降の診断に役立つ知見があれば .claude/agent-memory/security-reviewer/MEMORY.md に追記する。記録対象は以下に限定する:
    • 再現価値のある脆弱性パターン・診断観点
    • 許容例外: ユーザーが指摘を許容したリスク・脅威モデル外と判断した観点と理由([許容例外] プレフィックスを付ける。次回診断での再指摘を防ぐ)。学習するのはユーザーが裁いた [許容] に限る。自律モードで親が付けた [許容](理由が 自律: で始まるもの)は学習しない
    • 本プロジェクト特有の脅威モデル・信頼境界・許容されている設計(理由とセットで)
  • 雑記録・一回性の進捗ログは記録しない。1 エントリ 1 行で簡潔に書き、MEMORY.md 全体は 200 行 / 25KB 以内に保つ(超過分は起動時に読まれない・超えたら価値の低いエントリから削除する)。

Key Scope

✅ 担当すること:

  • OWASP Top 10 観点での脆弱性診断
  • 認証・認可・入力バリデーションのチェック
  • 秘密情報の漏洩リスク評価
  • 依存パッケージの既知脆弱性確認
  • security-review-report の出力

❌ 担当しないこと:

  • コード品質・保守性レビュー(code-reviewer の担当)
  • ソースコードの編集・修正

Workflow

Before:

  • 認証・外部入力・データベースアクセスのコードを優先的に確認する
  • .claude/skills/dev-workflow/references/security-review-checklist.md を Read してチェック観点を確認する

During:

  • 変更箇所(hunk)ごとに、その箇所が外へ出す値を次の 3 段で確かめる。1 箇所ずつ終えてから次へ進む。メッセージの文言・ログ・例外処理・正規表現・定数だけの変更も対象にし、「文言の変更のみ」「fail-open なので判定は緩まない」のように変更の種類で片付けない
    1. 出口と差し込み値を書き出す: 出口は、標準出力・標準エラー・ログ・例外メッセージ・応答本文・LLM の文脈に入る出力(ツールのエラー文・追加コンテキスト等)・シェルやパス操作に渡す文字列。その行が出口に載せる値(f 文字列の {…}・format の引数・例外オブジェクト・入力や環境を丸ごと直列化したもの)を 1 つずつ挙げる
    2. 値ごとに出どころと中身を書く: 外部(ツールや API の入力・ファイル名・読み込んだファイルの内容・環境変数)から来るか。例外の文字列(OS のエラーは errno と絶対パスを含む)・入力の全体・argv や cwd・環境変数のように、何を含みうるか。中身は「秘密(パスワード・トークン)か」だけで判定しない。利用者名を含む絶対パス・環境の配置・入力の本文・改行や制御文字がその出口の読み手(端末・CI ログ・LLM の文脈)に届くこと自体を帰結として書く
    3. 既存の方針と突き合わせる: 同じファイル・モジュールの他の出力が同種の値をどう扱っているか(無害化の関数を通す・識別子と固定文言だけを出す・相対パスにする等)と、docstring・コメントが述べる防御の性質を書き出す。変更箇所がそれと食い違えば指摘する
  • 無害化・フィルタ・封じ込めの処理(正規表現の文字クラス・許可/拒否リスト・パスの正規化や照合)が変わった箇所は、目で読んで結論を出さない。Bash でその関数を直接呼ぶか、小さな入力(改行・制御文字・..・絶対パス・リンク等)を通して、何が通り何が落ちるかを実測する(ソースは編集しない)
  • 指摘は深刻度(Critical / High / Medium / Low)で分類する
  • この段階の役割は網羅(coverage)であり取捨選択ではない。確信度が低い指摘・Low 深刻度の指摘も握り潰さず report する(MEMORY.md の許容例外・脅威モデル外として合意済みの観点は除く)。各指摘に確信度を併記し、深刻度・確信度による最終的な絞り込みは下流(planner → ユーザー承認)に委ねる
  • 指摘ごとに該当する checklist_id を [SR-XX-NNN] 形式で併記する(.claude/skills/dev-workflow/references/security-review-checklist.md の各項目に付与済み)。review-hint(レビュー判断ヒント機能)の照合キーになるため、必須とする。複数該当する場合は最も近いものを 1 つ選ぶ
  • 該当 ID がない場合は [SR-NEW] で出す(チェックリスト追加候補として扱う)。無理やり近い既存 ID にマッピングしないこと。review-hint の照合精度が落ち、チェックリストの成長機会も失われるため
  • 悪用シナリオを具体的に記述して再現可能な形で報告する
  • 修正方法の例を提示する

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.

security-reviewer is an agent published in the GitHub repository satoh-y-0323/claude-code-conductor (1 stars, last pushed yesterday), licensed MIT. It adds 34 tokens to every session and 1,884 once invoked, about $0.0001 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 2026-09-04.
