feat: Implement PR merge state verification to prevent wasted review effort#322
Conversation
Session 85 lessons learned implementation plan: - Add PR merge state verification to pr-review command (Skill-PR-Review-006) - Create Test-PRMerged.ps1 script for GraphQL merge state checking - Document Thread Resolution Protocol (Skills PR-Review-004, -005) - Update Completion Criteria with merge verification Prevents wasted effort on already-merged PRs where gh pr view returns stale data.

Implements Session 85 lessons learned to prevent wasted effort on merged PRs. Changes: - Create Test-PRMerged.ps1 script to check PR merge state via GraphQL * Exit code 0 = not merged (safe to proceed) * Exit code 1 = merged (skip review work) * GraphQL API is source of truth (gh pr view may return stale data) - Update pr-review command (.claude/commands/pr-review.md): * Add PR merge state verification to Step 1 * Add Thread Resolution Protocol section (Skills PR-Review-004, -005) * Update Completion Criteria with PR merge check - Thread Resolution Protocol documentation: * Single thread resolution (Skill-PR-Review-004) * Batch thread resolution using GraphQL mutation aliases (Skill-PR-Review-005) * Verification commands Testing: - ✅ Test-PRMerged.ps1 with merged PR #315 (exit code 1) - ✅ Test-PRMerged.ps1 with open PR #320 (exit code 0) Benefits: - Prevents wasted effort when gh pr view returns stale state - Reduces API calls via batch thread resolution (N calls → 1 call) - Documents 2-step process: reply + resolve thread Related: Session 85, PR #315, PR #320 Fixes #321
Comprehensive documentation of PR review improvements implementation. Deliverables: - Issue #321 created - Test-PRMerged.ps1 PowerShell script - pr-review.md updates (merge verification + thread resolution protocol) - Implementation plan document - PR #322 created Benefits: - Prevents wasted effort on merged PRs - Reduces API calls via batch thread resolution - Documents critical 2-step process (reply + resolve thread) Session metrics: - 45 minutes implementation time - 3 skills implemented (PR-Review-004, -005, -006) - 2 tests executed (merged PR #315, open PR #320) - 182 lines of code Related: Session 85, Issue #321, PR #322

Code Review
This pull request introduces a valuable check to prevent wasted review effort on already-merged PRs by using the GraphQL API as the source of truth. The new PowerShell script Test-PRMerged.ps1 is well-structured and includes documentation. The updates to pr-review.md clearly integrate this new check and add important documentation on thread resolution protocols.
My review focuses on improving the security and robustness of the new PowerShell script to align it with the repository's style guide and established best practices. I've identified a high-severity GraphQL injection vulnerability and a couple of medium-severity issues related to error handling. Applying these suggestions will make the script more secure and resilient, and ensure it adheres to repository standards for new code.

Pull request overview
This PR implements Session 85 lessons learned to prevent wasted review effort on already-merged PRs. It addresses a critical workflow gap where stale PR state data from gh pr view led to unnecessary work on PR #315, which had already been merged.
Key Changes
- New PowerShell script (
Test-PRMerged.ps1) that queries GraphQL API directly to verify PR merge state, avoiding stale cached data - Enhanced pr-review workflow with pre-review merge state verification and documented thread resolution protocols
- Comprehensive planning document detailing implementation strategy, test cases, and risk mitigation
