What problem does it solve? Coordinating a complete feature across database design, backend services, frontend components, testing, and deployment is complex and error-prone when done ad hoc. This Skill provides a structured, phase-by-phase workflow that delegates each layer to specialized subagents, ensuring API-first contract-driven development from architecture through production rollout. ## Core Features & Use Cases - Phased Orchestration: Four phases covering architecture design, parallel implementation, integration testing, and deployment operations, each with defined inputs and expected outputs. - Specialized Agent Delegation: Routes work to database architects, backend/frontend developers, test automators, security auditors, and deployment engineers via the Task tool. - API-First Contract Testing: Enforces OpenAPI/GraphQL contract validation between backend and frontend before E2E testing and security audits. - Use Case: A team needs to ship a new user notifications feature spanning PostgreSQL schema changes, a FastAPI service, and a React UI. The Skill sequences schema design, API contract definition, parallel backend/frontend builds, contract and E2E tests, security review, and CI/CD setup with feature flags. ## Quick Start Ask the AI to orchestrate a full-stack feature by describing the feature to implement, for example: build a notifications system with React frontend, FastAPI backend, and PostgreSQL database.
