What problem does it solve?

This Skill helps you quickly choose and implement a clean Python backend approach for APIs, validation, and background work without blindly following defaults.

Core Features & Use Cases

• Framework selection (FastAPI, Django, Flask): match the framework to whether you’re building API-first services, full-stack admin-heavy apps, or lightweight scripts.
• Async vs sync endpoint strategy: decide async for I/O-bound concurrency and sync for CPU-bound work while avoiding unsafe mixing.
• Typing and Pydantic v2 integration: define typed public APIs and use Pydantic for request/response validation and serialization.
• Background tasks and error handling guidance: pick between in-process background tasks and distributed job queues, and shape consistent domain errors.
• Testing principles: structure unit/integration/E2E testing with appropriate tools and async test patterns.

Quick Start

Use kb-python to review your proposed Python backend design (framework choice, async strategy, typing, Pydantic v2 schemas, background tasks, and error format) and produce an implementation plan you can follow in your project.
