Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must carry the burden. It states 'public information' and '@return: a json object', giving some safety context. However, it does not disclose whether authentication is required, potential errors, or rate limits, leaving gaps in behavioral understanding.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
