Supervisor agents vs deterministic routers
When a supervisor agent is useful, when a policy router is safer, and how to combine both without losing control.
A supervisor agent is a judgment engine. A deterministic router is a policy engine. Production systems need to know which one is making each decision.
AstraRunner treats this as an execution-platform concern: the run needs durable state, traceable decisions, cost visibility, and enough structure for teams to review what happened after the agent finishes.
Patterns that work
- Use deterministic routing for ownership, priority, tenant, and budget rules.
- Use supervisor agents for ambiguous triage and synthesis.
- Log the supervisor prompt, candidate routes, and selected route.
- Let policy override the supervisor when risk is high.
Implementation checklist
- List decisions that must be deterministic.
- Add confidence and reason fields to supervisor outputs.
- Route low-confidence decisions to review.
- Regression-test routing examples before prompt changes.
Watch outs
- Supervisor agents can create opaque policy drift.
- Routing prompts become governance logic if left unchecked.
- A confident wrong route is still wrong.

How this fits the Astra stack
AstraRunner owns the operational path for agent work: orchestration, scheduling, approval gates, traces, costs, and role-agent handoffs. AstraMemory owns durable context and retrieval. AstraGenie turns those capabilities into product workflows for teams that want automation without rebuilding the platform layer.
