Module Gate
Gate: Agent Engineering Fundamentals
10 min
Check that you can separate model requests, context budgets, retrieval and state, and orchestration structures.
- 01Trace the boundaries around one model call
- 02Classify retrieval, state, memory, and durable execution mechanisms
- 03Choose the simplest fitting tool and orchestration structure
The fundamental boundaries
module review- A model call sees the context assembled for that request.
- A context window is a finite input-plus-output token budget.
- Retrieval selects information; RAG places selected evidence into a request.
- State, checkpoints, tasks, and memory have different scopes and lifetimes.
- Tools, loops, graphs, and multiple agents add different kinds of control.

A chat application shows ten prior turns, but the next request sends only the latest user message. What can the model directly use?
