Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full disclosure burden. Critically, it does not reveal that the tool writes to the store by default (save defaults to true in the schema), nor does it describe permissions, side effects, or reversibility — significant omissions for what is apparently a mutating operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
