# Finishing a Development Branch
## Overview
Guide completion of development work by presenting clear options and handling chosen workflow.
**Core principle:** Verify tests → Detect environment → 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:**
```bash
# 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: Detect Environment
Flowy
**Determine workspace state before presenting options:**
```bash
GIT_DIR=$(cd "$(git rev-parse --git-dir)" 2>/dev/null && pwd -P)
GIT_COMMON=$(cd "$(git rev-parse --git-common-dir)" 2>/dev/null && pwd -P)
```
This determines which menu to show and how cleanup works:
| State | Menu | Cleanup |
|-------|------|---------|
| `GIT_DIR == GIT_COMMON` (normal repo) | Standard 4 options | No worktree to clean up |
| `GIT_DIR != GIT_COMMON`, named branch | Standard 4 options | Provenance-based (see Step 6) |
| `GIT_DIR != GIT_COMMON`, detached HEAD | Reduced 3 options (no merge) | No cleanup (externally managed) |
### Step 3: Determine Base Branch
```bash
# 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?"
### Step 4: Present Options
**Normal repo and named-branch worktree — 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?
```
**Detached HEAD — present exactly these 3 options:**
```
Implementation complete. You're on a detached HEAD (externally managed workspace).
1. Push as new branch and create a Pull Request
2. Keep as-is (I'll handle it later)
3. Discard this work
Which option?
```
**Don't add explanation** - keep options concise.
### Step 5: Execute Choice
#### Option 1: Merge Locally
```bash
# Get main repo root for CWD safety
MAIN_ROOT=$(git -C "$(git rev-parse --git-common-dir)/.." rev-parse --show-toplevel)
cd "$MAIN_ROOT"
# Merge first — verify success before removing anything
git checkout <base-branch>
git pull
git merge <feature-branch>
# Verify tests on merged result
<test command>
# Only after merge succeeds: cleanup worktree (Step 6), then delete branch
```
Then: Cleanup worktree (Step 6), then delete branch:
```bash
git branch -d <feature-branch>
```
#### Option 2: Push and Create PR
```bash
# Push branch
git push -u origin <feature-branch>
```
**Do NOT clean up worktree** — user needs it alive to iterate on PR feedback.
#### Option 3: Keep As-Is
Report: "Keeping branch <name>. Worktree preserved at <path>."
**Don't cleanup worktree.**
#### Option 4: Discard
**Confirm first:**
```
This will permanently delete:
- Branch <name>
- All commits: <commit-list>
- Worktree at <path>
Type 'discard' to confirm.
```
Wait for exact confirmation.
If confirmed:
```bash
MAIN_ROOT=$(git -C "$(git rev-parse --git-common-dir)/.." rev-parse --show-toplevel)
cd "$MAIN_ROOT"
```
Then: Cleanup worktree (Step 6), then force-delete branch:
```bash
git branch -D <feature-branch>
```
### Step 6: Cleanup Workspace
**Only runs for Options 1 and 4.** Options 2 and 3 always preserve the worktree.
```bash
GIT_DIR=$(cd "$(git rev-parse --git-dir)" 2>/dev/null && pwd -P)
GIT_COMMON=$(cd "$(git rev-parse --git-common-dir)" 2>/dev/null && pwd -P)
WORKTREE_PATH=$(git rev-parse --show-toplevel)
```
**If `GIT_DIR == GIT_COMMON`:** Normal repo, no worktree to clean up. Done.
**If worktree path is under `.worktrees/` or `worktrees/`:** Superpowers created this worktree — we own cleanup.
```bash
MAIN_ROOT=$(git -C "$(git rev-parse --git-common-dir)/.." rev-parse --show-toplevel)
cd "$MAIN_ROOT"
git worktree remove "$WORKTREE_PATH"
git worktree prune # Self-healing: clean up any stale registrations
```
**Otherwise:** The host environment (harness) owns this workspace. Do NOT remove it. If your platform provides a workspace-exit tool, use it. Otherwise, leave the workspace in place.
## Quick Reference
| Option | Merge | Push | Keep Worktree | Cleanup Branch |
|--------|-------|------|---------------|----------------|
| 1. Merge locally | yes | - | - | yes |
| 2. Create PR | - | yes | yes | - |
| 3. Keep as-is | - | - | yes | - |
| 4. Discard | - | - | - | yes (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?" is ambiguous
- **Fix:** Present exactly 4 structured options (or 3 for detached HEAD)
**Cleaning up worktree for Option 2**
- **Problem:** Remove worktree user needs for PR iteration
- **Fix:** Only cleanup for Options 1 and 4
**Deleting branch before removing worktree**
- **Problem:** `git branch -d` fails because worktree still references the branch
- **Fix:** Merge first, remove worktree, then delete branch
**Running git worktree remove from inside the worktree**
- **Problem:** Command fails silently when CWD is inside the worktree being removed
- **Fix:** Always `cd` to main repo root before `git worktree remove`
**Cleaning up harness-owned worktrees**
- **Problem:** Removing a worktree the harness created causes phantom state
- **Fix:** Only clean up worktrees under `.worktrees/` or `worktrees/`
**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
- Remove a worktree before confirming merge success
- Clean up worktrees you didn't create (provenance check)
- Run `git worktree remove` from inside the worktree
**Always:**
- Verify tests before offering options
- Detect environment before presenting menu
- Present exactly 4 options (or 3 for detached HEAD)
- Get typed confirmation for Option 4
- Clean up worktree for Options 1 & 4 only
- `cd` to main repo root before worktree removal
- Run `git worktree prune` after removal
