Does it cover routing and middleware?

Yes, it offers patterns for path-based and method-based routing, as well as strategies for handling CORS, authentication, and request validation at the edge.

Can I use this skill for TypeScript Worker projects?

Absolutely. The skill follows modern best practices including full TypeScript support, official type definitions, and type-safe environment binding patterns.

How does this skill help with Worker performance?

It provides guidance on minimizing CPU time, utilizing edge caching via the Cache API, and using ctx.waitUntil() for non-blocking background tasks.

Does this skill support D1, R2, and KV bindings?

Yes, it includes detailed implementation patterns and configuration guidance for D1 SQL databases, R2 object storage, KV namespaces, and Durable Objects.

What is the Cloudflare Workers Development skill?

It is a specialized capability for Claude that provides domain-specific knowledge for building, debugging, and deploying serverless functions on Cloudflare's global edge network.
