Repository Cleanup

Full repository hygiene: safely migrate to the default branch, delete merged and squash-merged branches, and produce a per-branch status report. No destructive operations without confirmation.

When to Use

Session start, after merging PRs, between tasks, before /ai-brainstorm.
NOT for committing -- use /ai-commit.

Process

Phase 0: Safe Migration (`--sync` or `--all`)

Detect default branch -- git symbolic-ref refs/remotes/origin/HEAD (main or master).
Record current branch for the report.
Auto-stash if dirty -- git stash push -m "cleanup-auto-stash-$(date +%s)".
Switch to default -- git checkout <default>.
Pull latest -- git pull --ff-only origin <default>. If ff-only fails: WARN and STOP.
Restore stash -- git stash pop. If conflict: WARN, leave stash, continue cleanup.

Phase 1: Branch Analysis (`--branches` or `--all`)

Fetch and prune -- git fetch --prune origin.
Enumerate all local branches (excluding main, master).
Classify each branch:

Category	Criteria	Action
Merged	In `git branch --merged <default>`	Delete (`git branch -d`)
Squash-merged	Not in `--merged` but `git diff <default>..<branch>` is empty	Delete (`git branch -D`)
Gone (safe)	Tracking ref `[gone]` AND no content diff	Delete (`git branch -D`)
Gone (has dev)	Tracking ref `[gone]` BUT has content diff	KEEP
Active	Has remote tracking, not merged	KEEP
Local only	No remote, has commits ahead	KEEP

Delete eligible -- merged with -d, squash-merged and gone-safe with -D.

Phase 2: Status Report

Build per-branch table:

## Repository Cleanup Report

**Default branch**: `main` (up to date)
**Previous branch**: `feat/old-feature`
**Working tree**: clean | stash restored | stash pending

| Branch | Action | Reason | Remote | Ahead/Behind |
|--------|--------|--------|--------|--------------|
| `feat/done` | DELETED | Merged | -- | -- |
| `feat/squashed` | DELETED | Squash-merged | -- | -- |
| `feat/active` | KEPT | Unmerged (5 commits) | origin/feat/active | +5/-2 |

Quick Reference

/ai-cleanup              # full: sync + branch cleanup + report
/ai-cleanup --sync       # sync to default branch only
/ai-cleanup --branches   # branch cleanup only (no migration)
/ai-cleanup --all        # explicit full cleanup

Common Mistakes

Force-pulling when ff-only fails -- STOP and resolve manually.
Deleting branches with unmerged local work -- always check content diff.
Running on main -- migration is a no-op but branch cleanup still runs.

Integration

Run before /ai-brainstorm to start clean.
Composes with session start protocol.
Protected branches (main, master) are never deleted.
