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 the current directory has no .git/ directory, read $CLAUDE_PLUGIN_ROOT/skills/init/references/multi-repo-detection.md and apply it. 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, 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/ (staged, not committed). 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.
