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 structures that implementation workflow so nothing is skipped. ## Core Features & Use Cases - Spec-Driven Implementation: Executes the work described in a spec or ticket set directly on the current branch. - Test-Driven Workflow: Applies TDD at pre-agreed seams, runs typechecking and single test files regularly, and runs the full test suite once at the end. - Built-In Review and Commit: Finishes with a code review pass and commits the completed work to the current branch. - Use Case: You have a ticket describing a new API endpoint. Invoke this Skill to implement it with tests, verify types and the test suite, review the changes, and commit the result. ## Quick Start Implement the work described in the current spec or tickets using test-driven development, then review and commit it.
