Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description discloses that 'No identifiers are retained,' which addresses privacy/retention behavior. However, it does not mention whether the tool is read-only, has side effects, or requires permissions. Since no annotations are provided, this partial disclosure is the only behavioral information available.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
