Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the burden. It adds useful behavior by stating it returns both HTML and text body, and the word 'Get' implies a read-only operation. However, it does not disclose potential error cases, permissions, or whether attachments are included, leaving some behavioral aspects undocumented.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
