Worktree

Create a git worktree under .worktrees/ on a new branch, with project setup and a test baseline. The main workspace stays on its original branch, so each worktree can host an independent Claude Code session.

Workflow

1. Target repo

If git rev-parse --is-inside-work-tree does not return true, read $CLAUDE_PLUGIN_ROOT/skills/init/references/multi-repo-detection.md and apply it. When it returns true, resolve the repository root with git rev-parse --show-toplevel, including in a linked worktree or subdirectory. In a multi-repo workspace, run all git commands inside the target child repo: use the repo the user specified; if ambiguous, use AskUserQuestion — header "Target repo", question "Which repo should the worktree be created for?", one option per repo.

2. Detection guard

Read $CLAUDE_PLUGIN_ROOT/skills/worktree/references/worktree-setup.md and run its worktree detection guard. If already inside a linked worktree, tell the user:

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

Then stop — never create nested worktrees.

3. Branch

Note the current branch as <original-branch>. Derive the task description from the invocation argument or the conversation; if neither gives enough signal, ask what the user will work on — follow up until you have a concrete description, not a category. Read $CLAUDE_PLUGIN_ROOT/skills/commit/references/branch-naming.md for the <type>/<slug> convention and collision handling, then create the branch without switching:

git branch <branch-name>

4. Create worktree

Follow the Setup procedure from worktree-setup.md with <branch-name> and <original-branch>. On failure, follow its Failure handling, delete the unused branch (git branch -d <branch-name>), then stop.

5. Report

## Worktree Created

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

Open it: `code .worktrees/<worktree-dir>` (VSCode), or start a new session of the current coding agent in that directory.
Cleanup when done: `git worktree remove .worktrees/<worktree-dir>`

If Setup modified .gitignore, add after "Main workspace": .gitignore updated to ignore .worktrees/ (left unstaged; existing index preserved). In a multi-repo workspace, prefix all report paths with the target repo directory.

Never commit or push in the main workspace; it must end on <original-branch>.

Recommend starting a fresh session inside the new worktree to begin the work there.
