Generate REST and GraphQL APIs with proper validation, error handling, and authentication. Function calling models understand API contracts and OpenAPI specs.
Write Prisma schemas, SQL migrations, and query optimizations. JSON mode produces structured database schemas and seed data.
Design microservices, message queues, and event-driven architectures. Reasoning models evaluate trade-offs between monolith and distributed approaches.
Implement OAuth, JWT, RBAC, and API rate limiting. Models understand security best practices, OWASP guidelines, and common vulnerability patterns.
