haiku	Auto-clean all stale worktrees (merged branches)

Clean Worktrees (Automatic)

Automatically clean all stale worktrees: merged branches and orphaned git references.

vs /tech:clean-worktree:

• /tech:clean-worktree: Interactive, asks confirmation
• /tech:clean-worktrees: Automatic, no interaction (safe: merged only)

Usage

/tech:clean-worktrees           # Clean all merged worktrees
/tech:clean-worktrees --dry-run # Preview what would be deleted

Implementation

#!/bin/bash
set -euo pipefail

DRY_RUN=false
if [[ "${ARGUMENTS:-}" == *"--dry-run"* ]]; then
  DRY_RUN=true

Safety Features

• ✅ Only merged branches: Never touches unmerged work
• ✅ Protected branches: Skips master and main
• ✅ Main repo: Never removes current working directory
• ✅ Remote branches: Reports but doesn't auto-delete
• ✅ Dry-run mode: Preview before deletion

When to Use

• After merging PRs into master
• Weekly maintenance
• Before creating new worktrees (keep things clean)

For unmerged branches: use /tech:remove-worktree <branch> (confirms deletion).
