FastAPI done right. Async patterns, dependency injection, Pydantic v2 models, middleware, and project structure.
Write secure-by-default Node.js and TypeScript applications following security best practices. Use when: (1) Writing new Node.js/TypeScript code, (2) Creating API endpoints or middleware, (3) Handling user input or form data, (4) Implementing authentication or authorization, (5) Working with secrets or environment variables, (6) Setting up project configurations (tsconfig, eslint), (7) User mentions security concerns, (8) Reviewing code for vulnerabilities, (9) Working with file paths or child processes, (10) Setting up HTTP headers or CORS.
Sets up Neon Auth in Next.js App Router applications. Configures API routes, middleware, server components, and UI. Use when adding auth-only to Next.js apps (no database needed).
Build with MPP (Machine Payments Protocol) - the open protocol for machine-to-machine payments over HTTP 402. Use when developing paid APIs, payment-gated content, AI agent payment flows, MCP tool payments, pay-per-token streaming, or any service using HTTP 402 Payment Required. Covers the mppx TypeScript SDK with Hono/Express/Next.js/Elysia middleware, pympp Python SDK, and mpp Rust SDK. Supports Tempo stablecoins, Stripe cards, Lightning Bitcoin, and custom payment methods. Includes charge (one-time) and session (streaming pay-as-you-go) intents. Make sure to use this skill whenever the user mentions mpp, mppx, machine payments, HTTP 402 payments, Tempo payments, payment channels, pay-per-token, paid API endpoints, or payment-gated services.
FastAPI integration testing specialist. Covers synchronous TestClient, async httpx AsyncClient, dependency injection overrides, auth testing (JWT, OAuth2, API keys), WebSocket testing, file uploads, background tasks, middleware testing, and HTTP mocking with respx, responses, and pytest-httpserver. USE WHEN: user mentions "FastAPI test", "TestClient", "httpx async test", "dependency override test", "respx mock", asks about testing FastAPI endpoints, authentication in tests, or HTTP client mocking. DO NOT USE FOR: Django - use `pytest-django`; pytest internals - use `pytest`; Container infrastructure - use `testcontainers-python`
Build Airflow 3.1+ plugins that embed FastAPI apps, custom UI pages, React components, middleware, macros, and operator links directly into the Airflow UI. Use this skill whenever the user wants to create an Airflow plugin, add a custom UI page or nav entry to Airflow, build FastAPI-backed endpoints inside Airflow, serve static assets from a plugin, embed a React app in the Airflow UI, add middleware to the Airflow API server, create custom operator extra links, or call the Airflow REST API from inside a plugin. Also trigger when the user mentions AirflowPlugin, fastapi_apps, external_views, react_apps, plugin registration, or embedding a web app in Airflow 3.1+. If someone is building anything custom inside Airflow 3.1+ that involves Python and a browser-facing interface, this skill almost certainly applies.
oRPC (v1.12+) typesafe API layer for TypeScript. Covers contract-first development, procedure definition, middleware, routers, context, error handling, Hono integration, TanStack Query, event iterators, plugins, file uploads, WebSocket adapter, and best practices. Use when building or modifying API procedures, data fetching hooks, server handlers, or real-time features. Triggers on tasks involving oRPC, typesafe APIs, RPC procedures, or server route handlers.
Apply when designing or modifying a BFF (Backend-for-Frontend) layer, middleware, or API proxy for a headless VTEX storefront. Covers BFF middleware architecture, public vs private API classification, VtexIdclientAutCookie management, API key protection, and secure request proxying. Use for any headless commerce project that must never expose VTEX_APP_KEY or call private VTEX APIs from the browser.
Go error handling patterns, wrapping, sentinel errors, custom error types, and the errors package. Grounded in Effective Go, Go Code Review Comments, and production-proven idioms. Use when implementing error handling, designing error types, debugging error chains, or reviewing error handling patterns. Trigger examples: "handle errors", "error wrapping", "custom error type", "sentinel errors", "errors.Is", "errors.As". Do NOT use for panic/recover patterns in middleware (use go-api-design) or test assertion errors (use go-test-quality).
NestJS framework best practices and production patterns. Use whenever working with NestJS — creating modules, controllers, services, DTOs, guards, interceptors, pipes, middleware, or building REST/GraphQL/microservice APIs. Also use when setting up authentication, authorization, validation, queues, health checks, WebSockets, caching, or any @nestjs/* package. Even for simple NestJS tasks, this skill ensures correct import paths, proper decorator usage, and production-ready patterns. Covers NestJS v11 with Express v5, native JWT auth, Zod validation, Keyv caching, and Suites testing.
Implements Syncfusion DataManager for local/remote binding, CRUD, querying, caching, and middleware. Supports JsonAdaptor, ODataAdaptor, ODataV4Adaptor, UrlAdaptor, WebApiAdaptor, WebMethodAdaptor, RemoteSaveAdaptor, GraphQLAdaptor, CustomDataAdaptor, and CustomAdaptor. Covers Query class, filtering, sorting, paging, grouping, persistence, offline mode, caching, and error handling.
Build high-performance APIs with Django-Bolt, including BoltAPI routes, typed request validation, msgspec serialization, auth guards, middleware, OpenAPI docs, pagination, streaming, SSE, WebSockets, and testing. Use when the user asks to create a new bolt endpoint, set up a Django-Bolt project, add JWT or API key auth, configure runbolt, wire guards or middleware, add pagination or streaming, generate OpenAPI docs, write TestClient tests, or migrate from FastAPI, Django REST Framework, or Django Ninja to django-bolt. Do NOT use for general Django views, Django admin customization, or standard Django REST Framework work.
