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 falling back to manual git worktrees. ## Core Features & Use Cases - Isolation Detection: Checks whether you are already inside a linked worktree or a git submodule before creating anything, avoiding duplicate or phantom worktrees. - Native Tool Preference with Git Fallback: Uses platform-native worktree tools (e.g., EnterWorktree) first, and only runs git worktree add when no native tool exists, with sandbox permission-error fallback to working in place. - Safe Directory Management: Selects .worktrees/ or worktrees/ directories, verifies they are git-ignored before creation, and commits the .gitignore update if needed. - Use Case: Before implementing a new feature, the agent detects you are on the main branch, creates .worktrees/feature-x with a new branch, installs dependencies, runs the test suite to confirm a clean baseline, and reports the workspace is ready. ## Quick Start Set up an isolated git worktree for my new feature branch and verify the project tests pass before I start implementing.
