Real-time bidirectional communication with security focus on CSWSH prevention, authentication, and message validation
Comprehensive guide for building GraphQL APIs including schema design, queries, mutations, subscriptions, resolvers, type system, error handling, authentication, authorization, caching strategies, and production best practices
FastAPI framework mechanics and advanced patterns. Use when configuring middleware, creating dependency injection chains, implementing WebSocket endpoints, customizing OpenAPI documentation, setting up CORS, building authentication dependencies (JWT validation, role-based access), implementing background tasks, or managing application lifespan (startup/shutdown). Does NOT cover basic endpoint CRUD or repository/service patterns (use python-backend-expert) or testing (use pytest-patterns).
Guidelines for building production-ready HTTP APIs with Deno and Hono framework. Use when creating REST APIs, web services, microservices, or any HTTP server using Deno runtime and Hono. Covers authentication, rate limiting, validation, and deployment patterns.
REST and GraphQL API design patterns, OpenAPI/Swagger specifications, versioning strategies, and authentication patterns. Use when designing APIs, reviewing API contracts, evaluating API technologies, or implementing API endpoints. Covers contract-first design, resource modeling, error handling, pagination, and security.
Implement OAuth 2.1 / OIDC authentication using Better Auth with MCP assistance. Use when setting up a centralized auth server (SSO provider), implementing SSO clients in Next.js apps, configuring PKCE flows, or managing tokens with JWKS verification. Uses Better Auth MCP for guided setup. NOT when using simple session-only auth without OAuth/OIDC requirements.
This skill should be used when the user asks to "connect to Trading 212", "authenticate Trading 212 API", "place a trade", "buy stock", "sell shares", "place market order",, "place pending order", "place limit order", "cancel order", "check my balance", "view account summary", "get positions", "view portfolio", "check P&L", "find ticker symbol", "search instruments", "check trading hours", "view dividends", "get order history", "export transactions", "generate CSV report", or needs guidance on Trading 212 API authentication, order placement, position monitoring, account information, instrument lookup, or historical data retrieval.
Automatically discover security skills when working with authentication, authorization, input validation, security headers, vulnerability assessment, or secrets management. Activates for application security, OWASP, and security hardening tasks.
Automatically discover API design skills when working with REST APIs, GraphQL schemas, API authentication, OAuth, JWT, rate limiting, API versioning, error handling, or endpoint design. Activates for backend API development tasks.
Publish articles to Toutiao (Today's Headlines). Handles persistent authentication (login once) and session management. Opens browser for interactive publishing.
Implement authentication and authorization using JWT, Basic Auth, or custom schemes. Use for securing API endpoints and user management.
Use when designing new REST APIs, reviewing API designs, establishing API standards, designing request/response formats, pagination, versioning, authentication flows, or creating OpenAPI specifications.
