Context Engineering and the Loop

This lesson explains what happens inside the agent you just started: how it builds its context and the three layers of memory. Each concept returns in the module that builds it.

• An agent acts only on what is in its context window when it is called
• If a rule, fact or email is not in the window, it does not exist
• Context is a design surface: the engineer decides what goes in
• Most failures in this workshop are context failures
