Finishing a Development Branch
Overview
Guide completion of development work by presenting clear options and handling chosen workflow.
Core principle: Verify tests → Present options → Execute choice → Clean up.
Announce at start: "I'm using the finishing-a-development-branch skill to complete this work."
The Process
Step 1: Verify Tests
Before presenting options, verify tests pass:
# Run project's test suite
npm test / cargo test / pytest / go test ./...
If tests fail:
Tests failing (<N> failures). Must fix before completing:
[Show failures]
Cannot proceed with merge/PR until tests pass.
Stop. Don't proceed to Step 2.
If tests pass: Continue to Step 2.
Step 2: Determine Base Branch
# Try common base branches
git merge-base HEAD main 2>/dev/null || git merge-base HEAD master 2>/dev/null
Or ask: "This branch split from main - is that correct?"
Read AGENTS.md and maintainer documentation, then inspect effective protection for the base branch. If pull requests or required checks are enforced, mark local merge as unavailable and use the repository's guarded PR/merge workflow. In agentic-awesome-skills, defer maintainer merges to antigravity-maintainer-batch-release and npm run merge:batch.
Step 3: Present Options
For an unprotected base branch, present exactly these 4 options:
Implementation complete. What would you like to do?
1. Merge back to <base-branch> locally
2. Push and create a Pull Request
3. Keep the branch as-is (I'll handle it later)
4. Discard this work
Which option?
Don't add explanation - keep options concise.
For a protected base branch, do not offer local merge. Present only push/create PR, keep as-is, and discard, while preserving the same confirmation rule for discard.
Step 4: Execute Choice
Option 1: Merge Locally
Use this option only after proving that repository policy and server-side protection permit local integration into the base branch. Otherwise stop and route through Option 2.
# Switch to base branch
git checkout <base-branch>
# Pull latest
git pull
# Merge feature branch
git merge <feature-branch>
# Verify tests on merged result
<test command>
# If tests pass
git branch -d <feature-branch>
Then: Cleanup worktree (Step 5)
Option 2: Push and Create PR
# Push branch
git push -u origin <feature-branch>
# Create PR
gh pr create --title "<title>" --body "$(cat <<'EOF'
## Summary
<2-3 bullets of what changed>
## Test Plan
- [ ] <verification steps>
EOF
)"
Then: Cleanup worktree (Step 5)
Option 3: Keep As-Is
Report: "Keeping branch . Worktree preserved at ."
Don't cleanup worktree.
Option 4: Discard
Confirm first:
This will permanently delete:
- Branch <name>
- All commits: <commit-list>
- Worktree at <path>
Type 'discard' to confirm.
Wait for exact confirmation.
If confirmed:
git checkout <base-branch>
git branch -D <feature-branch>
Then: Cleanup worktree (Step 5)
Step 5: Cleanup Worktree
For Options 1, 2, 4:
Check if in worktree:
git worktree list | grep $(git branch --show-current)
If yes:
git worktree remove <worktree-path>
For Option 3: Keep worktree.
Quick Reference
| Option | Merge | Push | Keep Worktree | Cleanup Branch |
|---|---|---|---|---|
| 1. Merge locally | ✓ | - | - | ✓ |
| 2. Create PR | - | ✓ | ✓ | - |
| 3. Keep as-is | - | - | ✓ | - |
| 4. Discard | - | - | - | ✓ (force) |
Common Mistakes
Skipping test verification
- Problem: Merge broken code, create failing PR
- Fix: Always verify tests before offering options
Open-ended questions
- Problem: "What should I do next?" → ambiguous
- Fix: Present exactly 4 structured options
Automatic worktree cleanup
- Problem: Remove worktree when might need it (Option 2, 3)
- Fix: Only cleanup for Options 1 and 4
No confirmation for discard
- Problem: Accidentally delete work
- Fix: Require typed "discard" confirmation
Red Flags
Never:
- Proceed with failing tests
- Merge without verifying tests on result
- Delete work without confirmation
- Force-push without explicit request
Always:
- Verify tests before offering options
- Present exactly 4 options
- Get typed confirmation for Option 4
- Clean up worktree for Options 1 & 4 only

When to Use
This skill is applicable to execute the workflow or actions described in the overview.
Limitations
- Use this skill only when the task clearly matches the scope described above.
- Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
- Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
