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, 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 in a linked worktree, a submodule, or a normal checkout before creating anything. - Native Tool Preference: Uses platform-native worktree tools (e.g. EnterWorktree, /worktree commands) when available, avoiding phantom state the harness cannot manage. - Safe Git Fallback: Creates worktrees in .worktrees/ or worktrees/ directories after verifying they are git-ignored, preventing accidental commits of worktree contents. - Use Case: Before implementing a new feature, the Skill sets up an isolated worktree, installs project 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 before starting work on a new feature branch.
