Comprehensive guidance for implementing asynchronous Python applications using asyncio, concurrent programming patterns, and async/await for building high-performance, non-blocking systems. 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 The workload is CPU-bound with minimal I/O. A simple synchronous script is sufficient. The runtime environment cannot support asyncio/event loop usage. 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. resour
