Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. It states this is an activation operation but doesn't describe what activation entails (e.g., does it enable features, start a subscription, require internet connectivity?), potential side effects, error conditions, or authentication requirements. This leaves significant gaps for a mutation tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
