Worktree Help
$ARGUMENTS is the user's question. If empty, MUST print the Overview section below byte-for-byte verbatim — do not paraphrase, summarize, or reorder. Otherwise, answer their question using the FAQ section as your primary reference, falling back to your knowledge of git worktrees and this plugin's setup.
Keep answers concise and practical. When relevant, include code .claude/worktrees/<branch-dir> — it's the single most useful tip for new users.
Overview (print when $ARGUMENTS is empty)
The empire worktree skills are a toolkit for running multiple branches of the same repo in parallel, each in its own isolated git worktree, with Claude Code skills that handle the lifecycle for you.
Why it exists. Switching branches mid-task is disruptive: you stash, rebuild, lose dev server state, and risk polluting one branch's .env with another's. Worktrees give each branch its own directory, dependencies, ports, and env — so you (or a Claude agent) can spin up a parallel task without touching what you're already working on. This plugin automates the boring parts: derived ports, copied env files, dependency installs, cleanup, and merge/close flows.
Zero per-repo setup. The plugin ships with worktree-setup.sh and the skills invoke it via ${CLAUDE_PLUGIN_ROOT}. Lockfiles are auto-detected (pnpm, npm, yarn, bun, uv, poetry, pipenv, bundler, cargo, go modules). The .claude/worktrees ignore entry is written to .git/info/exclude, never the repo's tracked .gitignore.

FAQ
Q: How do I see a worktree in VSCode?
Open it as its own window: code .claude/worktrees/<branch-dir>. The main repo's Source Control panel won't show worktree changes — that's by design (worktrees are excluded). Alternative: File → Add Folder to Workspace for a multi-root setup.
Q: Why is .claude/worktrees/ in .git/info/exclude?
Required. Worktrees are git's own checkout mechanism, not nested repos. Without an exclude entry, git would try to track the worktree's files as content of the parent repo. The plugin writes to .git/info/exclude (per-clone, not committed) so the host repo's tracked .gitignore stays untouched.
Q: What's the typical workflow?
/empire-git:worktree-open <task> → code .claude/worktrees/<branch-dir> → work & commit → /empire-git:worktree-close --push (or /empire-git:worktree-merge to fold into another branch first). Use /empire-git:worktree-list to see everything in flight.
Q: How do port offsets work?
Each worktree gets a deterministic 0–99 offset derived from its path. Same branch → same offset (bookmarkable). Different worktrees → near-zero collision odds. The script prints the offset on completion. If your app needs to read it, set PORT_OFFSET in the worktree's .env (manually or via your own post-setup hook) — the plugin no longer mutates .env automatically.
Q: What happens to .env files?
All .env* files are copied from the main repo into the worktree, preserving directory structure (monorepo-friendly). On --reopen, they're re-copied so worktrees pick up changes from the main repo. Symlinked .env files are skipped.
Q: How does dependency install work?
The script auto-detects the package manager from lockfiles in the worktree root: pnpm-lock.yaml → pnpm install --frozen-lockfile, yarn.lock → yarn install --frozen-lockfile, bun.lockb/bun.lock → bun install --frozen-lockfile, package-lock.json → npm ci, uv.lock → uv sync, poetry.lock → poetry install, Pipfile.lock → pipenv install --deploy, Gemfile.lock → bundle install, Cargo.lock → cargo fetch, go.sum → go mod download. No lockfile = skip.
Q: When should I use /empire-git:worktree-merge instead of opening a PR?
Two cases: batching small fixes (merge several tiny worktrees into one branch, open one PR), and branch decomposition (split a big feature into sub-worktrees, fold them back into the parent, then open one PR from the parent). For everything else, just /empire-git:worktree-close --push and PR normally.
Q: Can I run multiple worktrees at once?
Yes — that's the whole point. Each has isolated deps, ports, and env. Run /empire-git:worktree-list to see them all. A common pattern: one worktree for your main task, others for parallel Claude agents working on smaller things.
Q: How do I update dependencies in a worktree?
Run your normal install command inside the worktree directory (pnpm install, bun install, etc.). The worktree has its own node_modules — installs don't affect the main repo or other worktrees.
Q: What if I forget about a worktree?
/empire-git:worktree-list --stale shows worktrees with no recent activity. /empire-git:worktree-cleanup batch-removes stale ones (use --dry-run first to preview).
Q: Is the main repo affected when I work in a worktree?
No. The main repo's working directory, branch, and dev server are untouched. Only the shared .git directory is updated when you commit (which is the same as any branch switch).
Q: How do I delete a branch and its worktree completely?
/empire-git:worktree-close <branch> --force removes the worktree and deletes the local branch. Add --push first if you want to push before tearing down.
