Why Submilli
Governance
Make each agent’s authority explicit and reviewable. Apply defined policies consistently, with access scoped to the current session.
Define authority with BlueprintsCost efficiency
Let agents run a complete tool workflow as code. Send the model the result it needs instead of every intermediate response.
