Tool Function Schema Designer

If you're wiring up function calling for an LLM agent, this walks you through the whole stack: JSON schemas that match OpenAI's format, TypeScript interfaces for type safety, Zod validators to catch bad parameters before execution, and a registry pattern to manage multiple tools cleanly. The examples are practical, showing search functions with filters and sensible defaults. What I like is the error handling setup that distinguishes validation failures from execution errors, so your LLM can actually learn from mistakes. It's thorough without being academic, basically the checklist you'd want when adding tool use to a chatbot or agent system.
