AI Agents That Speak SQL: Text-to-SQL with Hugging Face smolagents

Short summary

Hugging Face's smolagents library implements a CodeAgent pattern using the ReAct framework to make Text-to-SQL significantly more robust than brittle single-pass LLM pipelines. Rather than generating SQL once, agents execute queries, observe results, and self-correct errors before responding. The tutorial includes complete working code examples for SQL tools, multi-table joins, and production-grade validation patterns.
