Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=false, idempotentHint=false, destructiveHint=false and openWorldHint=true, so the write/non-idempotent nature is covered structurally. The description adds nothing about what is created, required permissions, side effects, or what happens on duplicate submission, and its "viewed or edited" phrasing softly conflicts with a create-only endpoint.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
