What an agent runtime actually does

An agent is a loop: perceive → think → act → observe. A runtime is what makes that loop reliable, observable, and fast.

Three jobs of a runtime:

Route the model to tools safely
Persist state across steps (short-term + long-term memory)
Handle failures without losing work

By the end of this lesson you'll recognize those three jobs in every serious framework on the market.

Why this matters

If you've ever had an agent work beautifully in a notebook and then fall apart in production, you ran into a runtime issue. Prompting is necessary but not sufficient — the runtime is where agent businesses live or die.

Exercise

Open OpenClaw and print the state of a running workspace. Identify which values are perception (fresh from the world) and which are memory. Five minutes.
