What problem does it solve? Turning a written spec or set of tickets into working, verified code requires discipline: writing tests first, running typechecks, and reviewing the result. This Skill encodes that implementation workflow so the agent follows a consistent engineering process instead of ad-hoc edits. ## Core Features & Use Cases - Spec-Driven Implementation: Builds the work described in a spec or ticket set, using test-driven development at pre-agreed seams. - Continuous Verification: Runs typechecking and single test files regularly during development, then the full test suite once at the end. - Review and Commit: Finishes by running a code review pass over the changes and committing the work to the current branch. - Use Case: You have a ticket describing a new API endpoint. Invoke this Skill to implement it with tests first, verify types and tests pass, review the diff, and commit the finished work. ## Quick Start Implement the work described in the current spec or tickets using TDD, then review and commit it.
