What problem does it solve? Managing risky refactors, parallel agent tasks, or experimental changes in a single Git checkout risks breaking the active working environment and mixing half-finished work. This Skill provides a safe, structured protocol for creating, tracking, integrating, and cleaning up Git worktrees as isolated coding lanes. ## Core Features & Use Cases - Isolated Lane Management: Creates worktrees under .slim/worktrees/<slug>/ with consistent branch naming (omos/<slug>) and tracks lane state in a .slim/worktrees.json manifest. - Safety Guardrails: Enforces pre-flight checks, mandatory user confirmation before destructive Git operations, and managed .gitignore/.ignore blocks to keep lane artifacts local. - Four-Phase Workflow: Covers planning and setup, delegated execution inside the lane, diff-based integration with validation, and confirmed cleanup and pruning. - Use Case: When running multiple background agents on separate bugfixes, assign each agent its own worktree lane so their changes never conflict with the main checkout, then review diffs and merge each lane after approval. ## Quick Start Ask the AI to create a new worktree lane for your refactoring task, for example: set up an isolated worktree for the authentication refactor based on the main branch.
