What problem does it solve? Turning a written spec or set of tickets into committed, tested code requires coordinating implementation, testing, typechecking, and review. This Skill structures that process so the work is implemented, verified, and committed on the current branch. ## Core Features & Use Cases - Spec-Driven Implementation: Builds the work described in a spec or set of tickets provided by the user. - 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. - Review and Commit: Finishes by running a code review of the work and committing it 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 this spec or these tickets, using TDD where possible, then review and commit the changes.
