Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the behavioral disclosure burden. It does well by stating that this starts the personal router, deploys capital according to weights and risk caps, and pauses the main platform router while active. It also adds the ownership requirement for user_id, though it could say more about reversibility or error cases.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
