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, preferring native worktree tools, and falling back to manual git worktrees only when needed. ## 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 workspaces. - Native Tool Preference with Git Fallback: Uses platform-native worktree tools (e.g., EnterWorktree) when available, otherwise creates a worktree under a verified, git-ignored .worktrees/ directory. - Project Setup and Baseline Verification: Auto-detects Node.js, Rust, Python, or Go projects, installs dependencies, and runs the test suite to confirm a clean baseline before work begins. - Use Case: Before implementing a new feature branch, the Skill confirms you are not already isolated, creates .worktrees/feature-x, runs npm install and npm test, and reports a ready workspace with passing tests. ## Quick Start Set up an isolated git worktree for my new feature branch and verify the project tests pass before I start implementing.
