Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It does not explain what happens when 'solo' is true, false, or null, whether soloing a track unsolos others, or whether the operation is a toggle. This leaves the agent guessing about side effects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
