What problem does it solve? Working on a new feature often requires switching branches or stashing changes, which disrupts your current workspace. This Skill creates isolated git worktrees so you can develop features in parallel without touching your main working directory, while preventing common mistakes like committing worktree contents or starting from a broken baseline. ## 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 automatically if not. - Automated Project Setup: Auto-detects Node.js, Rust, Python, or Go projects and runs the appropriate dependency install, then runs the test suite to verify a clean baseline. - Use Case: You are about to implement an approved feature design. The Skill creates .worktrees/feature-auth on a new branch, runs npm install, confirms all 47 tests pass, and reports the workspace is ready. ## Quick Start Ask the AI to set up an isolated git worktree for your new feature branch before starting implementation.
