Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true, idempotentHint=true, openWorldHint=true and readOnlyHint=false, so the safety profile is carried by structured data. The description adds the semantic framing 'revoke trusting', which clarifies what is destroyed (the trust relationship, not the certificate itself), but says nothing about downstream impact on deployments, required permissions, or error conditions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
