Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description adds useful context beyond the annotations: comments are public, should not contain sensitive data, and do not change canonical lifecycle state. However, it does not reconcile this with destructiveHint=true or explain the mutating nature implied by readOnlyHint=false. No outright contradiction exists because it only denies canonical lifecycle changes, not all state changes.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
