What problem does it solve? Starting feature work directly in your main checkout risks polluting your current branch and mixing unrelated changes. This Skill ensures every implementation task begins in an isolated workspace, using native worktree tools when available or git worktree as a fallback. ## Core Features & Use Cases - Isolation Detection: Checks whether you are already inside a linked worktree or a submodule before creating anything, avoiding duplicate or phantom worktrees. - Native Tool Preference with Git Fallback: Uses platform-native worktree tools (e.g., EnterWorktree) first, falling back to git worktree add with directory selection, .gitignore verification, and sandbox permission handling. - Project Setup and Baseline Verification: Auto-detects Node.js, Rust, Python, or Go projects, installs dependencies, and runs the test suite to confirm a clean baseline before work begins. - Use Case: Before implementing a new feature branch, run this Skill to spin up an isolated worktree at .worktrees/feature-x, install dependencies, and confirm all tests pass. ## Quick Start Ask the AI to set up an isolated git worktree for your next feature branch and verify the project tests pass before starting implementation.
