Single Agent
Understand how one Agent is determined by model, tools, and context.
At the core, every Agent is determined by three things:
- Model
The model is the Agent's brain.
- Available tools
Tools are the Agent's hands and feet.
- 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.
