Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description bears full responsibility for behavioral disclosure. The verb 'retrieves' implies a read-only operation, but it doesn't mention whether there are any side effects, pagination behavior, or rate limits. For a simple list operation this is adequate but minimal, similar to the TDQS 4.3 example.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
