Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries the full burden. The verb 'Get' and 'settings' clearly signal a read-only, non-destructive operation, which is the main behavioral trait an agent needs. However, it does not mention authentication requirements, rate limits, or whether the settings response has any notable structure or defaults.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
