Does this skill cover Claude 3.7 and 4.5 models?

Yes, the skill provides specific implementation details for the latest models, including Claude 3.7 Sonnet's extended thinking and Claude 4.5's advanced capabilities.

Can I use these patterns in serverless environments?

Absolutely. The skill includes specific patterns for direct fetch requests and SSE streaming optimized for Cloudflare Workers and other serverless platforms.

How does this skill handle API rate limits?

It provides best practices for monitoring usage headers and implementing robust error handling for 429 (Too Many Requests) and other common API errors.

What is the difference between tool use and basic messaging?

Tool use allows Claude to define structured arguments for external functions, enabling the model to interact with your own APIs, databases, and local code.

How much can I save with prompt caching using this skill?

By implementing prompt caching as detailed in this skill, you can reduce input token costs by up to 90% and significantly decrease time-to-first-token for frequent requests.
