name: git-worktree

description: Manages git worktrees including listing, creating, removing, and switching between worktrees. Use when the user mentions creating worktrees, create a work tree, create worktree, new worktrees, parallel branches, or working on multiple branches simultaneously.

Git Worktree Management Skill

This skill helps you manage git worktrees efficiently. Git worktrees allow you to check out multiple branches simultaneously in different directories, which is useful for:

• Working on multiple features in parallel
• Testing different branches without losing work-in-progress
• Reviewing code while continuing development
• Quick bug fixes on main while working on a feature branch

Naming Convention

Worktrees should be created as sibling directories with a clear naming pattern:

Pattern: ../<repo-name>-wt-<branch-name>

Example: For a repo named "MyProject" with branch "feature/new-login":

/Users/username/source/myproject/              # Main repo
/Users/username/source/myproject-wt-feature-new-login/  # Worktree

Available Operations

List Worktrees

Show all existing worktrees with their paths and branches:

git worktree list

Example output:

/Users/username/source/myproject        c5b174796b4 [main]
/Users/username/source/myproject-wt-feature-auth   def5378 [feature/new-login]
/Users/username/source/myproject-wt-hotfix-crash   ghi9022 [hotfix/button-crash-fix]

Create a New Worktree

When creating worktrees, automatically use the naming convention:

For existing branches:

git worktree add ../<repo-name>-wt-<sanitized-branch-name> <branch-name>

For new branches:

git worktree add -b <new-branch-name> ../<repo-name>-wt-<sanitized-branch-name> <base-branch>

Note: Branch names with slashes (e.g., feature/new-login) should be sanitized by replacing / with - for the directory name.

Examples:

# Checkout existing feature branch
git worktree add ../myproject-wt-feature-auth feature/auth

# Create new feature branch from main
git worktree add -b feature/new-payment ../myproject-wt-feature-new-payment main

# Create hotfix worktree
git worktree add -b hotfix/critical-bug ../myproject-wt-hotfix-critical-bug main

Remove a Worktree

When you're done with a worktree:

# Remove worktree (must not have uncommitted changes)
git worktree remove ../<repo-name>-wt-<branch-name>

# Force remove even with uncommitted changes
git worktree remove --force ../<repo-name>-wt-<branch-name>

Prune Stale Worktrees

Clean up worktree metadata for manually deleted directories:

git worktree prune

Move a Worktree

Relocate an existing worktree (maintaining naming convention):

git worktree move <old-path> <new-path>

Lock/Unlock Worktrees

Prevent accidental deletion:

git worktree lock <path>
git worktree unlock <path>

Helper Functions

When creating worktrees, the skill should:

1. Get the repository name: Extract from the current directory name
2. Sanitize the branch name: Replace / with - for the path
3. Build the path: ../<repo-name>-wt-<sanitized-branch-name>

Example logic:

REPO_NAME=$(basename "$(git rev-parse --show-toplevel)")
BRANCH_NAME="feature/new-login"
SANITIZED_BRANCH=$(echo "$BRANCH_NAME" | sed 's/\//-/g')
WORKTREE_PATH="../${REPO_NAME}-wt-${SANITIZED_BRANCH}"

git worktree add "$WORKTREE_PATH" "$BRANCH_NAME"

Best Practices

1. Naming Convention: Always use <repo-name>-wt-<branch-name> pattern
2. Location: Keep worktrees as siblings to the main repo directory
3. Cleanup: Remove worktrees when done to avoid clutter
4. Branch Tracking: Each worktree tracks a different branch
5. Shared Objects: Worktrees share the same .git repository, saving disk space
6. Multiple Repos: The naming convention prevents confusion when multiple repos are in the same parent directory

Troubleshooting

Worktree Already Exists

If you get an error that a worktree already exists for a branch, you can:
1. Use git worktree list to find where it is
2. Remove the existing worktree first
3. Check out a different branch in the existing worktree

Locked Worktree

If removal fails due to a lock:

git worktree unlock <path>
git worktree remove <path>

Stale Worktree References

If worktrees were manually deleted:

git worktree prune

Branch Name Sanitization

Remember to replace / with - when creating directory names from branch names like feature/new-login → feature-new-login.

Integration with This Skill

When you ask me to:
- "List my worktrees" - I'll run git worktree list
- "Create a worktree for feature X" - I'll use the <repo-name>-wt-X naming pattern
- "Clean up worktrees" - I'll help remove old ones safely
- "Switch to worktree Y" - I'll navigate to the properly named directory
- "What worktrees exist?" - I'll list and explain them with full paths

This skill automatically applies the naming convention to keep your workspace organized, especially when managing multiple repositories in the same parent directory.
