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:**

# 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

**Determine workspace state before presenting options:**

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

# 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

# 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:

git branch -d <feature-branch>

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
)"

**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:

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:

git branch -D <feature-branch>

Step 6: Cleanup Workspace

**Only runs for Options 1 and 4.** Options 2 and 3 always preserve the worktree.

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/`, `worktrees/`, or `~/.config/superpowers/worktrees/`:** Superpowers created this worktree — we own cleanup.

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 f
