Function Calling With Multi Provider Schema Registry

via “function calling schema definition and multi-provider llm binding”

This repository contains the Hugging Face Agents Course.

Unique: Abstracts provider-specific function calling implementations (OpenAI tool_choice vs. Anthropic tool_use vs. open-source prompt engineering) behind a unified schema interface, allowing agents to work across multiple LLM providers without code changes. Teaches schema optimization patterns (enums, descriptions, required fields) that reduce LLM hallucination.

vs others: More portable than provider-specific function calling because it abstracts differences; more reliable than free-text tool invocation because schemas enforce structure and enable validation.
