What problem does it solve? Turning a written spec or set of tickets into committed, reviewed code requires coordinating test-driven development, typechecking, and review steps that are easy to skip or do inconsistently. ## Core Features & Use Cases - Spec-driven implementation: Executes the work described in a spec or ticket set on the current branch. - TDD at agreed seams: Applies test-driven development where pre-agreed, running typechecks and single test files regularly plus the full test suite at the end. - Built-in review and commit: Hands the finished work to a code review step and commits it to the current branch. - Use Case: After planning a feature with tickets, invoke this skill to implement the tickets with TDD, verify the full test suite passes, review the diff, and commit the result. ## Quick Start Implement the work described in the current spec and tickets, then review and commit it on this branch.
