📝 Walkthrough

Walkthrough

GitHub Actions workflow triggers are narrowed: claude-code-review.yml removes synchronize from pull request event types, claude.yml restricts issue events to opened only, and documentation is updated to reflect the expanded exclusion filter recommendation.

Changes

Cohort / File(s)	Summary
GitHub Actions Workflow Triggers .github/workflows/claude-code-review.yml, .github/workflows/claude.yml	Narrowed trigger conditions: removed synchronize event from PR triggers in claude-code-review.yml, and restricted issue triggers to opened events only in claude.yml.
Documentation .claude/commands/repo-maintenance.md	Updated recommended exclusion filter for synchronize trigger from [opened, ready_for_review] to [opened, ready_for_review, reopened].

🐰 With triggers now tightened and workflows refined,
We prune the excess events from the bind,
Each workflow now waits for just the right call,
Configuration perfected—less noise, more control! ✨

指摘事項（重大度順）

1. PR更新時にClaudeレビューが再実行されなくなる
   • 影響ファイル/行: .github/workflows/claude-code-review.yml:3-5
   • 内容: pull_request の types から synchronize を外したため、PRに新しいコミットがpushされてもレビューが走りません。初回レビュー後に修正コミットが積まれる運用だと、最新コードへのレビューが抜ける可能性が高いです（DX/品質リスク）。
   • 対応案: synchronize を戻す、または手動再実行の明確な運用（workflow_dispatch 追加など）を用意。

総合判定
patch is incorrect
理由: PR更新時の自動レビューが失われ、最新コードに対するレビュー保証が崩れるため。
