Build production-grade FastAPI backends with SQLModel, Dapr integration, and JWT authentication. Use when building REST APIs with Neon PostgreSQL, implementing event-driven microservices with Dapr pub/sub, scheduling jobs, or creating CRUD endpoints with JWT/JWKS verification. NOT when building simple scripts or non-microservice architectures.
Create API layer components for a new entity. Includes usecase interactors (internal/usecase/), proto definitions (schema/proto/), gRPC handlers (internal/infrastructure/grpc/), and DI registration. Use when adding CRUD endpoints or Step 3 of CRUD workflow (after add-domain-entity).
Design data models with Pydantic schemas, comprehensive validation rules, type annotations, and relationship mappings.
Handles custom ServiceNow API requests. Use for uncategorized endpoints. Triggers - advanced calls.
Manage API versioning strategy for Hono routes in apps/api/src/v1. Use when creating new API versions or migrating endpoints between versions.
JSON type-safe encoding and decoding using Daniel Bünzli's jsont library. Use when Claude needs to: (1) Define typed JSON codecs for OCaml record types, (2) Parse JSON strings to OCaml values, (3) Serialize OCaml values to JSON, (4) Handle optional fields and backwards compatibility, (5) Work with nested JSON structures
Test implementation of thin router skill for DiPeO backend. Provides decision criteria and documentation anchors for FastAPI server, CLI (dipeo run/results/metrics/compile/export), SQLite schema, and MCP integration in apps/server/. Use when task mentions CLI commands, server endpoints, database queries, or MCP tools.
Deno GraphQL 后端接口的完整开发指南. 当需要创建、修改后端 API 接口时使用此技能
This skill should be used when working with Convex actions, HTTP endpoints, validators, schemas, environment variables, scheduling, file storage, and TypeScript patterns. It provides comprehensive guidelines for function definitions, API design, database limits, and advanced Convex features.
Design and manage API contracts before implementation using OpenAPI and AsyncAPI specifications for contract-first development
Use when planning API versioning strategy, handling breaking changes, or managing API deprecation. Covers URL, header, and query parameter versioning approaches.
Build a basic HTTP request (curl or fetch) for an API. Use when a junior developer needs a quick request example.
Contract-first REST API design with OpenAPI 3.1 specification
Author and validate OpenAPI 3.1 specifications for REST API design, following API-first and contract-first development practices
Define consistent API error codes and responses. Use when a mid-level developer needs error standardization.
Thin HTTP layer controllers. Controllers contain zero domain logic, only HTTP concerns. Use when working with controllers, HTTP layer, web vs API patterns, or when user mentions controllers, routes, HTTP responses.
Custom exceptions with static factories and HTTP responses. Use when working with error handling, custom exceptions, or when user mentions exceptions, custom exception, error handling, HTTP exceptions.
GraphQL API design specialist for schema architecture, resolver patterns, federation, and performance optimization
Builds production-grade GraphQL APIs with proper schema design, resolvers, and security. This skill should be used when users want to create GraphQL APIs, design schemas, implement resolvers, or add GraphQL to existing applications.
