What problem does it solve? Turning a written spec or set of tickets into working, tested code requires discipline: writing tests first, running typechecks, and reviewing the result. This Skill structures that entire implementation workflow so nothing gets skipped. ## Core Features & Use Cases - Spec-Driven Implementation: Builds the work described in a spec or ticket set, following test-driven development at pre-agreed seams. - Continuous Verification: Runs typechecking and single test files regularly, then the full test suite once at the end. - Built-In Review and Commit: Finishes with a code review pass and commits the work to the current branch. - Use Case: You have a ticket describing a new API endpoint. Invoke this Skill to implement it with TDD, verify types and tests, review the diff, and commit the finished change. ## Quick Start Implement the work described in the current spec or tickets using test-driven development, then review and commit it.
