Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden for behavioral disclosure. 'List all advanced reports' implies a read-only operation that returns multiple items, but it doesn't specify whether this includes pagination, sorting, filtering, or what format the results take. For a list operation with zero annotation coverage, this leaves significant behavioral questions unanswered.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
