clean-worktrees

Clean Worktrees (Automatic)

Automatically remove all worktrees for branches merged into the default branch (main or master). No interaction required.

Usage

/clean-worktrees              # Remove all merged worktrees
/clean-worktrees --dry-run    # Preview what would be deleted

Implementation

Execute this script:

#!/bin/bash
set -euo pipefail

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

# Detect default branch (main or master)
DEFAULT_BRANCH=$(git symbolic-ref refs/remotes/origin/HEAD 2>/dev/null | sed 's|.*/||' || \
                 git branch --list main master 2>/dev/null | head -1 | xargs || \
                 echo "main")
