AI Engineering

Name the harm. Do not rehearse it. A signed list of what the bot must never say.

The desk lived on a laptop and the lid closed. Docker, a machine that stays on, a ledger so two copies answer a customer once, a queue, a worker, and an alert that rings a phone.

A stranger ran up the bill writing an essay, and the vendor had an outage mid sale. Two doors: one caps who may knock and how hard, one holds the keys and the backup vendor.

A small set of real mail, rerun on purpose. Silence and a thumbs-up are not proof.

The whole thread, the last few turns, or a summary. The ticket wins when they disagree.

LangChain, LangGraph, CrewAI, AutoGen, and MCP. A person still approves before money moves.

Rules, tools, a small model, a strong model, a person. Fine-tune a habit only after the file has failed.

Reuse a stable how-to. Do not cache a live price or someone else's order.

RAG, chunking, word search versus meaning, and what to do when yesterday's return window is still in the bot's mouth.

Pydantic checks the fields. A promise of a refund is a box the program can reject. The model does not press send.
