Harness Engineering: The Model Is a Component, the Harness Is the Product
The harness is the code that decides what the model sees, what it can touch, and what happens when it's wrong. Swap the model and your product survives. Get the harness wrong and no model saves you.

Agentic systems are simple to start and hard to stop. Loop engineering is the discipline of designing termination, progress detection, error feedback, and budget — the parts that decide whether your agent finishes or spins.
Read noteTool Design for LLM Agents: APIs for a Consumer That Can't Read the Docs
A tool for an agent is an API whose only consumer reads the signature once, has no memory of past mistakes, and will confidently guess when unsure. That changes almost every design decision.

Send me the product, bottleneck, or workflow you keep thinking about. I’ll help you turn it into a clear next step, a scoped build, or working software.
