Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=false, destructiveHint=false, and openWorldHint=true, and the description adds nothing further — no mention of required admin/owner privileges, whether the creator becomes an owner, billing/plan implications, or what happens on name collision. For a state-changing, open-world creation call this is a substantial gap, though not a contradiction.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
