Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=false, idempotentHint=true, destructiveHint=false and openWorldHint=true, so the description owes context about what gets replaced or requires authorization. Instead it adds only the misleading 'viewed' framing and says nothing about full-replacement semantics, required permissions, or the opaque request body.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
