Summary
A Nowcast data engineer describes building a multi-agent coding agent from scratch in Python with LangChain and Azure OpenAI GPT-4.1, originally for an internal generative-AI contest within the Finatext group. The system pairs a ProgrammerAgent that generates code with tools for reading, writing and branching files, a ReviewerAgent that reviews diffs, runs pytest and records LGTM, and an AgentCoordinator that loops the two until the reviewer approves or an iteration limit is reached; the post walks through the tool design and shows example runs.
