Web Backend Spec

Category: Engineering  ·  Sub-category: backend  ·  Last updated:
lang:python
Augment a sprint's SPEC.md with a Backend section (API contract, data model changes, authn/authz, validation, observability, contract test plan) tailored to the detected stack (Express/Fastify/Next/FastAPI/Django/Go/Rails/etc). Coordinator-only — does not write production code. Pauses for user confirmation. Run before /magi:tasks.

From the source SKILL.md

You are the coordinator. Add a backend-specific section to a sprint's SPEC.md. You do not write production code. Read references/domain/web/backend.md before starting.
