What problem does it solve? Starting feature work directly in your main checkout risks polluting the current branch and mixing unrelated changes. This Skill ensures every piece of feature work happens in an isolated workspace, detecting existing isolation first and falling back to manual git worktrees only when no native tool exists. ## Core Features & Use Cases - Isolation Detection: Runs git rev-parse checks to determine whether you are already inside a linked worktree or a submodule before creating anything, avoiding nested or duplicate worktrees. - Native Tool Preference: Uses platform-native worktree tools (such as EnterWorktree or a /worktree command) when available, falling back to manual git worktree add only when necessary. - Safe Directory Management: Selects .worktrees/ or worktrees/ directories, verifies they are git-ignored before creation, and handles sandbox permission errors gracefully. - Baseline Verification: Auto-detects the project type (Node.js, Rust, Python, Go), installs dependencies, and runs the test suite to confirm a clean starting state. - Use Case: Before implementing a new feature branch, ask your agent to set up an isolated workspace; it will create a worktree at .worktrees/feature-x, install dependencies, and confirm all tests pass before coding begins. ## Quick Start Ask your agent to set up an isolated git worktree for the new feature branch and verify the baseline tests pass before starting implementation.
