This is your go-to when you need to design REST, GraphQL, or gRPC APIs from scratch or fix architectural issues. It includes complete reference specs (OpenAPI 3.1, GraphQL SDL, Protocol Buffers) and a validation script that catches common mistakes like verb-based URLs, missing pagination, and leaky error responses. The anti-patterns section alone is worth the activation,it calls out real problems like N+1 queries in GraphQL resolvers and missing idempotency keys. Works best at the design phase before you've written implementation code. Pairs naturally with data-pipeline-engineer for the database layer underneath and devops-automator when you're ready to deploy.
