How does it handle function calling?

It provides standardized JSON schemas and recursive loop patterns to handle tool calls and response processing effectively within chat completions.

What error handling is included?

It provides strategies for handling 16 documented errors, including rate limits (429), API failures, and specific TypeScript type mismatches.

Are embeddings covered for RAG development?

Yes, the skill includes documentation and implementation guides for text-embedding-3-small and text-embedding-3-large models for building vector search systems.

Does this skill support the latest GPT-5 models?

Yes, it includes full support for the GPT-5 series (including 5.1 and 5.2), covering new parameters like reasoning_effort and verbosity.

Can I use this with Cloudflare Workers?

Absolutely. The skill provides specific implementation patterns for both the official Node.js SDK and the standard fetch-based approach required for edge environments.
