Single Agent

Understand how one Agent is determined by model, tools, and context.

At the core, every Agent is determined by three things:

  1. Model

The model is the Agent's brain.

  1. Available tools

Tools are the Agent's hands and feet.

  1. All existing context

Context includes the system prompt and every relevant user / assistant message. It is the Agent's mind.

All context affects the Agent's behavior. The system prompt matters, but it is never the whole story.

Expanded, one by one

  • Model: pick the right brain for each Agent's role.
  • Tools: what the Agent can reach and change.
  • Context: build a clear mind from three kinds of context — constraints, information, task.
  • ReAct and Action Sequence: how a single Agent reasons while acting, and breaks a complex goal into executable stages.
