Documentation

Async Python Patterns

Comprehensive guidance for implementing asynchronous Python applications using asyncio, concurrent programming patterns, and async/await for building high-performance, non-blocking systems.

Use this skill when

●Building async web APIs (FastAPI, aiohttp, Sanic)

●Implementing concurrent I/O operations (database, file, network)

●Creating web scrapers with concurrent requests

●Developing real-time applications (WebSocket servers, chat systems)

●Processing multiple independent tasks simultaneously

●Building microservices with async communication

●Optimizing I/O-bound workloads

●Implementing async background tasks and queues

Do not use this skill when

●The workload is CPU-bound with minimal I/O.

●A simple synchronous script is sufficient.

●The runtime environment cannot support asyncio/event loop usage.

Instructions

●Clarify workload characteristics (I/O vs CPU), targets, and runtime constraints.

●Pick concurrency patterns (tasks, gather, queues, pools) with cancellation rules.

●Add timeouts, backpressure, and structured error handling.

●Include testing and debugging guidance for async code paths.

●If detailed examples are required, open resources/implementation-playbook.md.

Refer to resources/implementation-playbook.md for detailed patterns and examples.

firebase

"Firebase gives you a complete backend in minutes - auth, database, storage, functions, hosting. But the ease of setup hides real complexity. Security rules are your last line of defense, and they're often wrong. Firestore queries are limited, and you learn this after you've designed your data model. This skill covers Firebase Authentication, Firestore, Realtime Database, Cloud Functions, Cloud Storage, and Firebase Hosting. Key insight: Firebase is optimized for read-heavy, denormalized data.

graphql

"GraphQL gives clients exactly the data they need - no more, no less. One endpoint, typed schema, introspection. But the flexibility that makes it powerful also makes it dangerous. Without proper controls, clients can craft queries that bring down your server. This skill covers schema design, resolvers, DataLoader for N+1 prevention, federation for microservices, and client integration with Apollo/urql. Key insight: GraphQL is a contract. The schema is the API documentation. Design it carefully."
