Schema Driven Tool Definition With Automatic Validation

via “structured-output-tool-definition-framework”

What are the principles we can use to build LLM-powered software that is actually good enough to put in the hands of production customers?

Unique: Treats tools as declarative data structures with explicit schemas rather than imperative functions, enabling automatic validation, documentation generation, and type-safe tool invocation across LLM and deterministic code boundaries

vs others: More maintainable than function-based tool definitions because schema changes automatically propagate to LLM descriptions and validation logic, reducing inconsistencies between tool documentation and actual behavior
