What problem does it solve? Messy git worktrees, oversized mixed-scope PRs, and unverified merges slow down shipping and risk leaking gigabytes of untracked files into version control. This Skill enforces a strict one-worktree, one-goal, one-PR discipline with hard guards and merge gates. ## Core Features & Use Cases - Worktree safety guards: Shell scripts hard-fail if .worktrees/ is not gitignored, block nested worktree creation, and verify clean preflight state before any git worktree add. - Merge gate enforcement: Requires lint, build, test, floor checks, Vercel preview, and production HTTP verification before a PR counts as done, with PR size limits per change type. - Forensic cleanup mode: Read-only audit scripts, mandatory backup bundles, domain classification, and a removal gate for safely recovering from hundreds of dirty or untracked paths. - Use Case: Before starting a new feature branch, run the preflight scripts to confirm the tree is clean and gitignored, create a worktree from origin/main, ship one focused PR through the merge gate, then verify production before starting the next task. ## Quick Start Ask the agent to start a new worktree for a task and it will run the guard scripts, create the worktree from origin/main, and guide the change through the focused PR merge gate.
