What problem does it solve? Starting feature work directly in your current checkout risks polluting your active 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 (such as EnterWorktree or a /worktree command) when available, avoiding phantom state that manual git commands would create. - Safe Git Fallback: Selects a worktree directory (.worktrees/ preferred), verifies it is git-ignored, creates the branch and worktree, then runs project setup and baseline tests. - Use Case: Before implementing a new feature on a repository with an active main branch, activate this Skill to spin up an isolated worktree, install dependencies, and confirm a clean test baseline before writing code. ## Quick Start Ask the AI to set up an isolated worktree workspace before starting implementation of your next feature.
