Graph Engineering

I spent three weeks debugging one agent that kept lying to me. The fix wasn't a better prompt. It was a diagram.

You’ve built an agent that works perfectly for ten minutes and then starts making things up.

You’ve blamed the model. You’ve added “do not hallucinate” in capital letters like that was ever going to work.

It’s not the model. It’s not your prompt. You gave one agent four jobs and a context budget for one.

This issue is the fix.

By the end of this issue, you will get The Graph Engineering Blueprint. The thing I wish someone had handed me three weeks ago.

ANNOUNCEMENT

We’re stepping up to three newsletters a week. It’s a deliberate choice: enough volume to stay useful, enough care to stay worth your time.

After reading this issue, you stop prompting agents and start designing systems. The first one is replaceable. The second one gets hired.
