Branch Finish

Guide completion of development work by presenting clear options and handling the chosen workflow.

Core principle: Verify tests -> Detect environment -> Present options -> Execute choice -> Clean up.

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

Invoke the pr-style skill for PR formatting, or delegate to /pr:create.

# Push branch
git push -u origin <feature-branch>

Do NOT clean up worktree -- the branch needs to stay alive for PR iteration.

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:

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/: We own this worktree -- clean it up.

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  # Clean up any stale registrations

Otherwise: The host environment owns this workspace. Do NOT remove it.

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)
