• langchain-v1-migration-audit

  Crawls a folder of Jupyter notebooks / Python files in this AI ENGINEERING repo, finds every LangChain 0.x pattern that breaks or is deprecated on LangChain 1.x (legacy chains, AgentExecutor/initialize_agent/create_react_agent, *Memory classes, moved imports, .text(), agent-node renames), and produc

• langchain-v1-pipeline

  Runs the entire LangChain 1.x migration pipeline end to end on one folder, unattended — audit → plan → task board → explainer notebooks → independent review loop → close tasks → roll the plan up to complete.
