Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The statement 'No identifiers are retained' provides some transparency about data handling, but does not describe other behaviors such as side effects, read-only nature, or whether any state is modified. With no annotations present, the description carries partial responsibility for behavioral disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
