Building a self-corrective coding assistant from scratch

LangGraph makes it easy to engineer flows with various cycles and decision points. Recent work by CodiumAI has shown that this is powerful for code generation, where answers to coding questions can be constructed iteratively using using tests to check answers, reflect on failures, and iteratively improve the answer. In this video, we show how these ideas can be implemented in LangGraph to build a coding assistant from scratch. We apply it to the LangChain Expression Language docs.
