Here's what's inside a 5-minute lesson on “agent harness”.

01 · THE RIGHT MEANING

It tells you which meaning is in the room.

Eval harnessruns a model through tests
Agent harnesswhat people mean now
02 · 1 PICTURE

1 picture, and it clicks.

The model is the horse. The harness is everything that steers it. You'll still remember it next month.

A horse pulling a cart to market. Horse equals the model, harness equals everything that steers it.
03 · REAL CASES

You use it, not just read it.

2 teams use the same model. Team A's agent forgets what it did yesterday. What's broken?
The model
The harness: memory ✓
Nothing
Right. Memory lives in the harness, not the model.
04 · PROOF

Explain it back. See what you missed.

Reading feels like learning. Saying it in your own words is proof.

Educket checks your 2-line explanation and shows what you missed.
05 · KEEP IT

A card you can use in the meeting.

AGENT HARNESS
Everything around an AI model that lets it do real work: instructions, tools, memory and checks.
Say it like“The model is the horse. The harness is how we steer it.”
