using-git-worktrees

To isolate feature work, the skill detects existing isolation and automatically creates a dedicated git worktree. It ensures project-local directories are ignored by git and validates baseline test health before proceeding with feature implementation.

Using git worktrees prevents workspace pollution by ensuring new feature development occurs in an isolated, clean environment rather than the primary branch. This avoids context switching overhead and keeps dependencies isolated during development.

To ignore build artifacts, the skill verifies that worktree directories are properly ignored by git. It applies safety guardrails to prevent accidental commits of build artifacts during isolated feature development.

The skill applies native tool preferences when creating isolated workspaces. If native tools are unavailable, it falls back to executing git-native commands with safety checks to ensure proper workspace isolation.

A key limitation is that baseline test health must be validated before proceeding with implementation. The skill prevents workspace contamination but requires passing safety checks and proper gitignore configuration to function correctly.
