Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided. Description only says 'Fetch', implying read-only, but does not disclose any behavioral traits like whether it requires authentication, is destructive, or has rate limits. The term 'flattened' hints at output format but no further detail.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
