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. 'Get recently updated notes' implies a read-only operation but doesn't specify sorting order (e.g., most recent first), whether it includes deleted notes, pagination behavior, or performance characteristics. For a tool with no annotation coverage, this leaves significant gaps in understanding its behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
