GitHub PR Merge

Merges Pull Requests after validating pre-merge checklist and handling post-merge cleanup.

Quick Start

# 1. Get PR info
PR=$(gh pr view --json number -q '.number')
REPO=$(gh repo view --json nameWithOwner -q '.nameWithOwner')

# 2. Run pre-merge checklist
make test && make lint && gh pr checks $PR

# 3. Verify all comments replied
gh api repos/$REPO/pulls/$PR/comments --jq '[.[] | select(.in_reply_to_id == null)] | length'

# 4. Merge with concise message
gh pr merge $PR --merge --delete-branch --body "- Change 1
- Change 2

Reviews: N/N addressed
Tests: X passed"

# 5. Post-merge cleanup
git checkout develop && git pull && git branch -d feature/<name>

Pre-Merge Checklist

ALWAYS verify before merging:

make test

make lint

gh pr checks $PR

Core Workflow

1. Identify PR

PR=$(gh pr view --json number -q '.number')
REPO=$(gh repo view --json nameWithOwner -q '.nameWithOwner')
echo "PR #$PR in $REPO"

2. Check Comments Status

# Count original comments (not replies)
ORIGINALS=$(gh api repos/$REPO/pulls/$PR/comments --jq '[.[] | select(.in_reply_to_id == null)] | length')

# Count comments that have at least one reply
REPLIED=$(gh api repos/$REPO/pulls/$PR/comments --jq '
  [.[] | select(.in_reply_to_id)] | [.[].in_reply_to_id] | unique | length
')

echo "Original comments: $ORIGINALS, With replies: $REPLIED"

If unreplied comments exist:

• DO NOT reply from this skill
• STOP the merge process
• Inform user: "Found unreplied comments. Run pr-review first."

3. Run Validation

# Run tests
make test

# Run linting
make lint

# Check CI status
gh pr checks $PR

All checks MUST pass before proceeding.

4. Show PR Summary

gh pr view $PR --json title,body,commits,changedFiles --jq '
  "Title: \(.title)\nCommits: \(.commits | length)\nFiles: \(.changedFiles)"
'

5. Confirm with User

ALWAYS ask before merging:

Pre-merge checklist verified:
- Tests: passing
- Lint: passing
- CI: green
- Comments: all replied

Ready to merge PR #X. Proceed?

6. Execute Merge

gh pr merge $PR --merge --delete-branch --body "$(cat <<'EOF'
- Key change 1
- Key change 2
- Key change 3

Reviews: N/N addressed
Tests: X passed
Refs: Task N
EOF
)"

Note:

--delete-branch

7. Post-Merge Cleanup

git checkout develop
git pull origin develop
git branch -d feature/<branch-name>  # local cleanup

Merge Message Format

Concise format (recommended):

- Key change 1 (what was added/fixed)
- Key change 2
- Key change 3

Reviews: 7/7 addressed
Tests: 628 passed (88% cov)
Refs: Task 8

Guidelines:

• 3-5 bullet points max for changes
• One line for reviews summary
• One line for test results
• One line for task references
• Total: ~10 lines max

Important Rules

• ALWAYS run full pre-merge checklist before merging
• ALWAYS verify all review comments have replies
• ALWAYS confirm with user before executing merge
• ALWAYS use merge commit (--merge), never squash/rebase
• ALWAYS delete feature branch after successful merge
• NEVER merge with failing tests or lint
• NEVER merge with unresolved CI checks
• NEVER skip user confirmation
• NEVER reply to PR comments from this skill - use pr-review instead
• STOP merge if unreplied comments exist
