What an agent is made of
Five fields do almost all the work.
| Field | What it does |
|---|---|
model | Which Gemini model answers |
name | Identifier, used when agents call each other |
description | How other agents decide to hand work to this one |
instruction | The system prompt. What this agent is and how it behaves |
tools | Python functions it is allowed to call |
description and instruction are not the same thing
instruction is read by this agent. description is read by other agents deciding whether to delegate here. Get the second one wrong and delegation silently stops working.This is what real progress feels like.
