What problem does it solve? Working on a new feature often requires switching branches, which disrupts your current workspace, stashes uncommitted changes, and risks mixing unrelated work. This Skill sets up isolated git worktrees so you can develop on a separate branch in a separate directory without touching your main checkout. ## Core Features & Use Cases - Smart Directory Selection: Follows a priority order (existing .worktrees/ or worktrees/ directory, then CLAUDE.md preference, then asks the user) to pick a consistent worktree location. - Safety Verification: Checks with git check-ignore that project-local worktree directories are gitignored before creation, and fixes the .gitignore if not, preventing accidental commits of worktree contents. - Automated Setup and Baseline Validation: Auto-detects project type (Node.js, Rust, Python, Go) to install dependencies, then runs the test suite to confirm a clean baseline before implementation begins. - Use Case: You are about to implement an approved feature design and need isolation from your current workspace. The Skill creates .worktrees/feature-auth on a new branch, runs npm install, verifies all 47 tests pass, and reports the worktree is ready. ## Quick Start Set up an isolated git worktree for my new feature branch and verify the tests pass before I start implementing.
