What problem does it solve? Setting up a git worktree for parallel feature work or PR review normally requires manual steps: copying .env files, trusting mise/direnv configs, and updating .gitignore. This Skill automates that setup so a new worktree is ready to use immediately without disturbing the main checkout. ## Core Features & Use Cases - Automated Worktree Creation: Creates a worktree under .worktrees/<branch> from a specified base branch, fetching the base ref without modifying the main checkout. - Environment File Copying: Copies .env, .env.local, .env.test and similar files from the main repo while skipping .env.example and backing up existing files. - Branch-Aware Dev Tool Trust: Auto-trusts mise and direnv configs only when they match a trusted baseline branch, skipping direnv allow on untrusted review branches for safety. - Use Case: While reviewing a teammate's PR, create an isolated worktree with bash scripts/worktree-manager.sh create feat/login so your main checkout stays free for your own in-progress work. ## Quick Start Ask the assistant to create a worktree for your branch by running the worktree-manager script with a meaningful branch name like feat/login.
