👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |

Warning Review limit reached
Next review available in: 26 minutes You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository. How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window. Please refer docs for additional details.

In @.gitleaks.toml:
- Around line 236-239: Extend the URL regex in the gitleaks rule to include
localtunnel.me alongside the existing tunnel domains, so
https://<subdomain>.localtunnel.me is detected and matches the documented
leak-prevention targets.
- Around line 218-239: Update the validation fixtures for the visible rules
monopo-ai-token-assignment and monopo-local-tunnel-url: use quoted API-key
assignments matching the rule’s required quote syntax, and use a supported
tunnel domain such as localtunnel’s configured domain, or expand the rule regex
to include the intended fixture domain. Ensure the fixtures are validated with
Gitleaks v8.30.1 rather than BetterLeaks.
- Around line 222-225:
AIトークン検知用のregexを、変数名境界を付けて対象キーそのものだけに一致させ、値の形式や長さに依存せず検出できるよう更新してください。引用符の有無、空白、`$`、`.`、Unicode、短い値を扱える値captureを追加し、`secretGroup`がそのcaptureを指すよう調整してください。`MY_OPENAI_API_KEY`を誤検知しないことを含め、関連fixtureで各形式と境界条件を検証してください。
- Around line 226-231: Update the dummy allowlist rule in [rules.allowlist] so
it captures only the placeholder value, sets secretGroup to 1, and uses
regexTarget = "secret". Anchor the regex with ^ and $ to allow only complete
intended dummy placeholders, excluding values such as dummy-real-looking-secret.

背景
対象リポジトリは React 19, Vite, Bun を用いたアプリケーションであり、既に Gitleaks, Secretlint, Trivy, CodeQL 等が導入済みで強固な防御層を持っています。しかし、AI エージェントを多用する開発環境において、独自のフォーマットを持つ AI トークン(例:
GH_MODELS_TOKENへの任意文字列の代入)や、デバッグ目的で使用されるローカルトンネル(ngrok等)の URL がハードコードされてしまうリスクに対する網羅的な防止策が不足していました。現状認識(事前調査結果のサマリー)
gitleaks.yml,codeql.yml,trivy.yml,.pre-commit-config.yaml導入済み。.envファイル等の流出はないものの、ワークフロー等で多数利用されるGH_MODELS_TOKENや一時的なデバッグ環境が誤ってコミットされる潜在的リスクが存在。このPRで導入・強化するもの
.gitleaks.tomlカスタムルールおよびdocs/security/leak-prevention.mdへの追記。GH_MODELS_TOKENやTAVILY_API_KEYのような変数への直接代入を検知。またngrok-free.app等のデバッグURLを検知し、コミット・Push 前にブロック。検知漏れリスクと補完策
