Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=false, openWorldHint=true, idempotentHint=false, destructiveHint=false, but the description adds nothing on top: it doesn't say what is mutated, whether SSO configuration changes affect authentication, or whether partial omission preserves existing values. With a mutation tool whose annotations are already thin, this is a serious gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
