Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The phrase 'No identifiers are retained' discloses a privacy-related behavioral trait, which is useful. However, since no annotations are provided, the description carries the full burden; other aspects like side effects, permissions, or rate limits are not mentioned, so transparency is only partial.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
