Worktree Management

Git worktrees let you check out multiple branches of the same repository into separate directories simultaneously. Each worktree has its own working directory and index while sharing the same .git object store and history. This is useful for running parallel development sessions, reviewing a PR while mid-feature, or isolating experimental changes without stashing or committing half-finished work.

Core Principles

Quick Reference

Create

Create a new worktree for an isolated parallel development session.

Workflow

1. Confirm the current directory is a git repository.
2. Confirm the current session is NOT already inside a worktree: git rev-parse --is-inside-work-tree && git worktree list If the current working directory is already a worktree (not the main working tree), warn the user and stop.
3. If a name was provided as an argument, use it. Otherwise, present an interactive prompt (or the platform's equivalent): "What name should I use for this worktree? (e.g., feature-auth, bugfix-123)"
4. Create the worktree: git worktree add.worktrees/<name> -b worktree-<name>
5. Change your working directory to the new worktree path.
6. Report to the user: Worktree created: Directory:.worktrees/<name>/ Branch: worktree-<name> Based on: <current HEAD>
7. Remind the user:

- Run your stack's dependency installation command (e.g., composer install, npm install, pip install -r requirements.txt) - The worktree shares git history with the main repo but has its own working directory - Use the list command to see all active worktrees - Use the remove command to clean up when done

List

List all active worktrees with their branches, paths, and status.

Workflow

1. Confirm the current directory is inside a git repository.
2. Run: git worktree list --porcelain
3. For each worktree, gather uncommitted change count: git -C <worktree-path> status --short 2>/dev/null
4. Display a clean table: Active worktrees: | # | Name | Branch | Path | Status | |---|--------------|----------------------|-------------------------------|---------------| | 1 | (main) | main | /path/to/repo | clean | | 2 | feature-auth | worktree-feature-auth|.worktrees/feature-auth | 3 uncommitted | | 3 | bugfix-123 | worktree-bugfix-123 |.worktrees/bugfix-123 | clean |
5. If no worktrees exist beyond the main working tree, say: "No additional worktrees found. Use the create command to create one."

Switch

Switch your working directory to a different existing worktree.

Workflow

1. Confirm the current directory is inside a git repository.
2. Run: git worktree list If only the main working tree exists, say: "No worktrees available to switch to. Use the create command to create one." and stop.
3. If a name was provided as an argument, find the matching worktree path. Otherwise, show the list and present an interactive prompt (or the platform's equivalent): "Which worktree do you want to switch to?"
4. If the name does not match any existing worktree, say: "Worktree <name> not found." and show the available list.
5. Open a terminal in the worktree path, or switch your editor to the worktree directory.
6. Report to the user: Switched to worktree: Directory: <worktree-path> Branch: <branch-name>
7. Show a quick status: git status --short

Remove

Remove one or all worktrees from the current repository.

Workflow

1. Confirm the current directory is inside a git repository.
2. Run: git worktree list If no worktrees exist beyond the main working tree, say: "No worktrees to clean up." and stop.
3. Determine what to remove:

- If argument is all -- remove all worktrees (except the main working tree). - If a specific name was provided -- remove only that worktree. - If no argument -- show the list and present an interactive prompt (or the platform's equivalent): "Which worktree should I remove? Enter the name, or type all to remove everything."

1. Safety check -- for each worktree being removed: git -C <worktree-path> status --short git -C <worktree-path> log --oneline @{upstream}..HEAD 2>/dev/null If there are uncommitted changes or unpushed commits, warn the user: WARNING: Worktree "<name>" has uncommitted changes / unpushed commits: - 2 modified files - 1 unpushed commit These will be permanently lost. Continue? (yes/no) Wait for explicit confirmation before proceeding.
2. For each worktree to remove: git worktree remove <path> --force git branch -D worktree-<name> 2>/dev/null Use --force only after the user has confirmed in step 4.
3. Prune stale entries: git worktree prune
4. Report what was removed: Removed worktrees: - feature-auth (branch worktree-feature-auth deleted) - bugfix-123 (branch worktree-bugfix-123 deleted) Remaining worktrees: 1 (main working tree only)
