Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It states the tool 'Get's settings, implying a read-only operation, but does not disclose any behavioral traits such as authentication requirements, rate limits, or what happens if settings are unavailable. The description is minimal but not misleading.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
