Developer builds TypeScript tool to validate LLM structured output

A developer has created a TypeScript tool to validate structured output from large language models, addressing issues like parsing errors, missing fields, and schema violations. The tool, named "tiny-schema-gate," simulates responses from models like Anthropic's Claude Haiku 5.5 and OpenAI's models, demonstrating how to build a robust gate that rejects malformed or incomplete JSON outputs. This approach emphasizes the need for systems to handle LLM output errors gracefully, rather than just accepting valid JSON. AI

IMPACT Provides a practical solution for developers to ensure reliable structured data from LLMs, improving application robustness.
