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 but offers minimal information. It hints at a 'compatibility' status without explaining what that means for behavior, side effects, or versioning. Crucially, with no output schema present, the description fails to specify what 'details' are returned or their structure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
