Designing Multi-Agent Systems with Gemma 4: Supervisor and Worker Pattern

Most single-agent systems fail because one model tries to do everything, creating complexity and errors.

A better pattern separates narrow worker agents from a supervisor that coordinates, validates, and manages retries.

Gemma 4's thinking mode gives the supervisor structured internal reasoning to evaluate actions and select state transitions.

A state-driven flow of Trace, RootCause, Plan, Fix/Escalate, and Verify lets the supervisor control execution and make behavior traceable.

Implementations must validate outputs, limit retries, and distinguish reversible actions to be production-ready.
