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. While 'List' implies a read-only operation, it doesn't specify whether this requires authentication, how results are paginated, what the output format is, or any rate limits. The description lacks critical behavioral context needed for safe and effective use.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
