What problem does it solve?
The Backend Implementation Skill orchestrates the backend phase of Spec-Driven Development (SDD) projects by reading requirements.md (contract), plan.md (task groups), and handover.md (frontend context). It implements the plan.md groups in order using the code-harness, then runs architectural review (Opus) and integration testing against every API contract defined in requirements.md. Trigger on: /backend, or when the backend step is reached in the build process.
Core Features & Use Cases
- Orchestrates the backend phase by delegating tasks to the code-harness in the correct sequence.
- Validates the backend contract against the frontend expectations via architectural review and end-to-end API integration tests.
- Reads the latest specs directory (specs/YYYY-MM-DD-[feature]) to determine scope and acceptance criteria.
Quick Start
Point Claude Code at the latest specs/YYYY-MM-DD-[feature] directory and start the backend implementation phase.
