git-worktree-clean（git 工作树清理）

Worktree Clean

Clean up a worktree branch by fetching fresh state from origin and hard-resetting to a target branch.

Usage

/git-worktree-clean [branch]

Arguments:

• branch (optional): Target branch to reset to. Default: origin/latest

Help

If the user provides help as an argument:

• Explain how to use this command
• Explain prerequisites
• DO NOT proceed, exit immediately

Prerequisites

1. Git CLI must be available
2. Working directory should be a git worktree (not the main repository)
3. No critical uncommitted changes - warn user if dirty

Workflow

STEP 1: Verify Environment

# Check if we're in a git worktree
git rev-parse --is-inside-work-tree || exit 1

# Check for uncommitted changes
if [ -n "$(git status --porcelain)" ]; then
    echo "WARNING: Uncommitted changes detected"
    git status --short
fi

If uncommitted changes exist, STOP and ask user for confirmation before proceeding.

STEP 2: Fetch Fresh State

# Fetch latest from origin
git fetch origin

STEP 3: Hard Reset to Target

# Default to origin/latest if no argument provided
TARGET_BRANCH="${ARGUMENTS:-origin/latest}"

# Hard reset to target
git reset --hard "$TARGET_BRANCH"

STEP 4: Verify Clean State

# Show current state
git log --oneline -1
git status

Definition of Done

• Working tree is clean
• HEAD matches target branch
• User informed of reset result
