Worktree

Create a git worktree for isolated parallel development. Sets up a new branch in a separate directory (.worktrees/) with project setup and test baseline, so the main workspace stays untouched. Each worktree can host an independent Claude Code session.

Workflow

1. Multi-repo Detection

Read $CLAUDE_PLUGIN_ROOT/skills/init/references/multi-repo-detection.md for workspace detection. If a multi-repo workspace is detected:

• Run the git commands below inside each child repo (the workspace root has no .git/, so git commands must target individual repos)
• If the user specified a target repo (inline or in conversation), use it
• If ambiguous, use AskUserQuestion — header "Target repo", question "Which repo should the worktree be created for?": list each repo as an option

2. Worktree Detection Guard

Read $CLAUDE_PLUGIN_ROOT/skills/worktree/references/worktree-setup.md and run the worktree detection guard from that reference. If the guard detects you are already inside a linked worktree, inform the user:

Already running inside a worktree (`<worktree-path>`).
To create another worktree, run this skill from the main workspace instead.

Then stop — do not create recursive worktrees.

3. Gather Context and Branch Name

Record the current branch:

git rev-parse --abbrev-ref HEAD

Determine a meaningful description for the branch from the first source that provides enough signal (check in this priority order):

1. Inline description — if the user provided text with the invocation (e.g., /optimus:worktree "fix login timeout"), use it directly
2. Conversation context — scan the current conversation for the user's task intent, problem description, or feature request

If neither source provides enough signal, use AskUserQuestion — header "Worktree scope", question "What will you work on in the new worktree?":

• New feature — "Implement a new capability"
• Bug fix — "Fix a bug or issue"
• Other — "Describe the task"

Read $CLAUDE_PLUGIN_ROOT/skills/commit/references/branch-naming.md for the naming convention. Determine <type> and generate the slug from the description.

Handle collisions: if git show-ref --verify --quiet refs/heads/<branch-name> succeeds (branch exists), append -2 to the slug. If that also exists, try -3, and so on up to -9. If all collide, inform the user and stop.

Create the branch without switching to it:

git branch <branch-name>

4. Create Worktree

Follow the setup procedure from $CLAUDE_PLUGIN_ROOT/skills/worktree/references/worktree-setup.md using <branch-name> and <original-branch> from Step 3. The procedure handles:

• Deriving the worktree directory name
• Creating .worktrees/ and ensuring it is gitignored
• Creating the worktree: git worktree add .worktrees/<worktree-dir> <branch-name>
• Running project setup in the worktree (npm install, pip install, cargo build, etc.)
• Verifying the test baseline

If worktree creation fails, report the error with diagnostic information and stop.

5. Report and Next Steps

## Worktree Created

Working directory: `.worktrees/<worktree-dir>`
Branch: `<branch-name>` (from `<original-branch>`)
Main workspace: `<original-branch>` (unchanged)
Tests: passing / no test command detected

### Open the worktree

**VSCode** (recommended — each worktree gets its own window, terminal, and file watchers):
- Source Control panel → right-click the worktree → "Open Worktree in New Window"
- Or from terminal: `code .worktrees/<worktree-dir>`
- Or Command Palette → "Git: Open Worktree in New Window"

**Claude Code CLI**: `cd .worktrees/<worktree-dir> && claude`

### Cleanup

When done: `git worktree remove .worktrees/<worktree-dir>`

Recommend running /optimus:tdd in the new worktree for test-driven development, or /optimus:init if the worktree needs project setup.

Tell the user: Tip: for best results, start a fresh conversation for the next skill — each skill gathers its own context from scratch.

Important

• Never commit or push anything in the main workspace
• The main workspace branch is always restored to <original-branch>
• Worktrees are created inside .worktrees/ (gitignored) to keep the project root clean
