Building a Coding Agent with LangGraph Deep Agents

Building a coding agent with LangGraph Deep Agents: one createDeepAgent call, five seams (model, tools, backend, subagents, middleware) returning a compiled LangGraph graph.

A single LLM loop can’t reliably run a multi-step coding task. CodeBuddy is a deep agent instead: one createDeepAgent call composed from five seams (model, tools, file system, subagents, middleware) returning a compiled LangGraph graph, with four layers of self-healing. This is the whole architecture from the inside, grounded in the real code and file paths.
