What problem does it solve? Turning a spec or set of tickets into verified, committed code requires coordinating TDD, typechecking, test runs, quality gates, and review — this Skill orchestrates that entire implementation workflow so nothing is skipped. ## Core Features & Use Cases - Spec-driven implementation: Builds the work described in a spec or tickets, applying TDD at pre-agreed seams. - Layered verification: Runs typechecking and single test files regularly, the full test suite once at the end, then the quality gate in local mode and a code review at the router-assigned depth. - Scheduler lane mode: When dispatched as a bounded specialist by a scheduler, it edits and verifies without committing, runs the gate with a lane label, and returns a metric table so the scheduler can reconcile parallel lanes. - Use Case: A scheduler dispatches three parallel lanes to implement separate tickets; each lane edits code, runs a lane-labelled local quality gate, and returns metrics, while the scheduler performs the single reconciled commit. ## Quick Start Implement the work described in the current spec or tickets, run the local quality gate, review the changes, and commit to the current branch.
