How does this skill help with framework selection?

It uses a 2025 decision tree to evaluate your project needs—such as API-only vs. full-stack—and recommends the best fit among FastAPI, Django, and Flask.

Does it provide guidance on async programming?

Yes, it provides clear rules on when to use async (I/O-bound) versus sync (CPU-bound) and helps you select appropriate async libraries like httpx and asyncpg.

Can this skill help with project organization?

Absolutely. It offers standardized directory structures for small, medium, and large-scale applications, including patterns for organizing by feature or by layer.

What testing methodologies are included?

The skill covers unit, integration, and E2E testing strategies using pytest, with specific focus on handling async tests and effective fixture management.
