What problem does it solve? Feature work done directly in your main checkout risks polluting your current branch and mixing unrelated changes. This Skill ensures every implementation task starts 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: Checks whether you are already inside a linked worktree or a submodule before creating anything, avoiding duplicate or phantom worktrees. - Native Tool Preference: Uses platform-native worktree tools (like EnterWorktree or /worktree commands) when available, falling back to git worktree add only when necessary. - Safe Directory Handling: Selects .worktrees/ or worktrees/ directories, verifies they are git-ignored, and commits the ignore rule before creating the worktree. - Use Case: Before implementing a new feature, the Skill sets up an isolated worktree, installs dependencies (npm, cargo, pip, go), runs baseline tests, and reports a clean starting state. ## Quick Start Ask the assistant to set up an isolated worktree for your next feature and verify the project tests pass before starting implementation.
