It handles worktree creation with automatic port allocation, environment file management, secret copying, and cleanup — enabling developers to run multiple Claude Code instances on separate features simultaneously without conflicts. +Use this skill to run parallel feature work safely with Git worktrees. It standardizes branch isolation, port allocation, environment sync, and cleanup so each worktree behaves like an independent local app without stepping on another branch. + +This skill is optimized for multi-agent workflows where each agent or terminal session owns one worktree. ## Core Capabilities -- **Worktree Lifecycle Management** — create, list, switch, and cleanup worktrees with automated setup -- **Port Allocation & Isolation** — automatic port assignment per worktree to avoid dev server conflicts -- **Environment Synchronization** — copy .env files, secrets, and config between main and worktrees -- **Docker Compose Overrides** — generate per-worktree port override files for multi-service stacks -- **Conflict Prevention** — detect and warn about shared resources, database names, and API endpoints -- **Cleanup & Pruning** — safe removal with stale branch detection and uncommitted work warnings +- Create worktrees from new or existing branches with deterministic naming +- Auto-allocate non-conflicting ports per worktree and persist assignments +- Copy local environment files (`.env*`) from main repo to new worktree +- Optionally install dependencies based on lockfile detection +- Detect stale worktrees and uncommitted changes before cleanup +- Identify merged branches and safely remove outdated worktrees -## When to Use This Skill +## When to Use -- Running multiple Claude Code sessions on different features simultaneously -- Working on a hotfix while a feature branch has uncommitted work -- Reviewing a PR while continuing development on your branch -- Parallel CI/testing against multiple branches -- Monorepo development with isolated package changes +- You need 2+ concurrent branches open locally +- You want isolated dev servers for feature, hotfix, and PR validation +- You are working with multiple agents that must not share a branch +- Your current branch is blocked but you need to ship a quick fix now +- You want repeatable cleanup instead of ad-hoc `rm -rf` operations -## Worktree Creation Workflow +## Key Workflows -### Step 1: Create Worktree +### 1. Create a Fully-Prepared Worktree + +1. Pick a branch name and worktree name. +2. Run the manager script (creates branch if missing). +3. Review generated port map. +4. Start app using allocated ports. ```bash -# Create worktree for a new feature branch -git worktree add ../project-feature-auth -b feature/auth - -# Create worktree from an existing remote branch -git worktree add ../project-fix-123 origin/fix/issue-123 - -# Create worktree with tracking -git worktree add --track -b feature/new-api ../project-new-api origin/main +python scripts/worktree_manager.py \ + --repo . \ + --branch feature/new-auth \ + --name wt-auth \ + --base-branch main \ + --install-deps \ + --format text ``` -### Step 2: Environment Setup - -After creating the worktree, automatically: - -1. **Copy environment files:** - ```bash - cp .env ../project-feature-auth/.env - cp .env.local ../project-feature-auth/.env.local 2>/dev/null - ``` - -2. **Install dependencies:** - ```bash - cd ../project-feature-auth - [ -f "pnpm-lock.yaml" ] && pnpm install - [ -f "yarn.lock" ] && yarn install - [ -f "package-lock.json" ] && npm install - [ -f "bun.lockb" ] && bun install - ``` - -3. **Allocate ports:** - ``` - Main worktree: localhost:3000 (dev), :5432 (db), :6379 (redis) - Worktree 1: localhost:3010 (dev), :5442 (db), :6389 (redis) - Worktree 2: localhost:3020 (dev), :5452 (db), :6399 (redis) - ``` - -### Step 3: Docker Compose Override - -For Docker Compose projects, generate per-worktree override: - -```yaml -# docker-compose.worktree.yml (auto-generated) -services: - app: - ports: - - "3010:3000" - db: - ports: - - "5442:5432" - redis: - ports: - - "6389:6379" -``` - -Usage: `docker compose -f docker-compose.yml -f docker-compose.worktree.yml up` - -### Step 4: Database Isolation +If you use JSON automation input: ```bash -# Option A: Separate database per worktree -createdb myapp_feature_auth - -# Option B: DATABASE_URL override -echo 'DATABASE_URL="postgresql://localhost:5442/myapp_wt1"' >> .env.local - -# Option C: SQLite — file-based, automatic isolation +cat config.json | python scripts/worktree_manager.py --format json +# or +python scripts/worktree_manager.py --input config.json --format json ``` -## Monorepo Optimization +### 2.

Always install deps. -2. **Port conflicts** — Two dev servers on :3000 = silent failures. Always allocate unique ports. -3. **Database migrations** — Migrations in one worktree affect all if sharing same DB. Isolate. -4. **Git hooks** — Live in `.git/hooks` (shared). Worktree-specific hooks need symlinks. -5. **IDE confusion** — VSCode may show wrong branch. Open as separate window. -6. **Stale worktrees** — Prune regularly: `git worktree prune`. +1. Creating worktrees inside the main repo directory +2. Reusing `localhost:3000` across all branches +3. Sharing one database URL across isolated feature branches +4. Removing a worktree with uncommitted changes +5. Forgetting to prune old metadata after branch deletion +6. Assuming merged status without checking against the target branch ## Best Practices -1. Name worktrees by purpose: `project-auth`, `project-hotfix-123`, `project-pr-456` -2. Never create worktrees inside the main repo directory -3. Keep worktrees short-lived — merge and cleanup within days -4. Use the setup script — manual creation skips env/port/deps -5. One Claude Code instance per worktree — isolation is the point -6. Commit before switching — even WIP commits prevent lost work +1. One branch per worktree, one agent per worktree. +2. Keep worktrees short-lived; remove after merge. +3. Use a deterministic naming pattern (`wt-`). +4. Persist port mappings in file, not memory or terminal notes. +5. Run cleanup scan weekly in active repos. +6. Use `--format json` for machine flows and `--format text` for human review. +7. Never force-remove dirty worktrees unless changes are intentionally discarded. + +## Validation Checklist + +Before claiming setup complete: + +1. `git worktree list` shows expected path + branch. +2. `.worktree-ports.json` exists and contains unique ports. +3. `.env` files copied successfully (if present in source repo). +4.
