Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate readOnlyHint=false and destructiveHint=false. The description adds 'this modifies your Seerr instance,' but this is vague and doesn't disclose key behavioral traits like whether a test notification is sent, whether settings are written, or what side effects occur. It provides only minimal extra context beyond the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
