PR Finalize

Ensures PR title and description accurately reflect the implementation for a good commit message.

Works on any PR - Does not require agent involvement or session markdown.

Inputs

Outputs

1. Recommended PR title - Platform prefix, behavior-focused
2. Recommended PR description - NOTE block + structured content
3. Session markdown updates (only if file exists)

Completion Criteria

• Reviewed PR diff to understand actual implementation
• Verified title matches implementation (or recommended fix)
• Verified description matches implementation (or recommended fix)
• Checked for session markdown and updated if needed

When to Use

• Before merging any PR
• "Finalize PR #XXXXX"
• "Check PR description for #XXXXX"
• When implementation changed during review

When NOT to Use

• ❌ For analyzing lessons learned (use learn-from-pr skill instead)
• ❌ For writing or running tests (use write-tests or sandbox)
• ❌ For investigating why PR build failed (use pr-build-status)

Constraints

• Don't change PR title/description directly - Only recommend changes
• Don't modify code - Only verify title/description accuracy
• Match existing style - Follow PR template format
• Preserve user content - Enhance, don't replace custom descriptions

Workflow

Step 1: Get PR State

Copygh pr view XXXXX --json title,body,files
gh pr diff XXXXX
gh pr view XXXXX --json commits --jq '.commits[].messageHeadline'

Step 2: Analyze Implementation

Read the diff and understand:

• What was actually changed (not what was planned)
• Which platforms are affected
• What the fix does

Step 3: Verify Title

Step 4: Verify Description

Must include:

1. NOTE block (for testing PR artifacts)
2. Description of Change (matches actual implementation)
3. Issues Fixed

Should include (for agent context):

• Root cause
• Fix approach
• Key insight

Step 5: Session Markdown (If Exists)

Copyls .github/agent-pr-session/issue-XXXXX.md .github/agent-pr-session/pr-XXXXX.md 2>/dev/null

If file exists:

• Check if "Selected Fix: [PENDING]" → update with actual fix
• Add "ACTUAL IMPLEMENTED FIX" section if missing
• Document lessons learned

If file doesn't exist: Skip this step.

Step 6: Present Recommendations

Output recommended title and description.

Example

PR #33352 - MacCatalyst crash on window disposal

Step 1: Get PR State

Copygh pr view 33352 --json title,body,files
# Title: "Fix ObjectDisposedException in PageViewController"
