Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, openWorldHint=false and destructiveHint=false, covering the safety profile. The description adds that returned details include configuration/settings, which is useful content scope, but says nothing about permissions, token-scoped behavior, or how the result differs from get_settings. With annotations carrying the safety burden, this is an adequate but modest addition.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
