How do I access Cloudflare services like D1 or KV?

All Cloudflare bindings are accessed through the self.env object within the WorkerEntrypoint class, ensuring type-safe and consistent access to your infrastructure.

Does this skill support external Python packages?

Yes, it utilizes the pywrangler approach released in December 2025, which enables deploying Workers with external dependencies defined in your pyproject.toml.

What are Python Workflows?

Python Workflows allow for durable, multi-step automation with automatic retries and state persistence, using a specific decorator pattern optimized for Python's syntax.

Can I use synchronous libraries like 'requests'?

No, Cloudflare Workers run in an async-only environment. This skill helps you implement asynchronous alternatives like httpx or aiohttp to prevent runtime errors.

Cloud Infrastructure

Builds and deploys production-ready Python APIs and durable workflows on Cloudflare Workers using modern class-based patterns.

This skill provides specialized guidance for developing Python applications on Cloudflare's edge runtime using the WorkerEntrypoint class pattern and the pywrangler CLI. It enables developers to implement complex, durable automation via Python Workflows, manage external package dependencies via the latest Dec 2025 updates, and integrate seamlessly with Cloudflare bindings like D1, KV, and R2. By addressing 11 documented Pyodide compatibility issues and async-only constraints, it streamlines the migration of Python services to the edge while ensuring adherence to current best practices.
