About this skill

What it does. Gathers requirements and acceptance criteria, documents a technical design, then checks authentication, authorisation, validation and output encoding before implementation. Builds and tests frontend and backend components incrementally, with security notes and a handoff for QA or deployment.

When to use it. For end-to-end web features such as CRUD flows, authenticated APIs with views, microservices or real-time functionality. Also applies to architecture and technology choices; it is not intended for frontend-only, backend-only or API-only work.
