Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations declare readOnlyHint=false and destructiveHint=false, so the mutation/safety profile is partially covered by structured data. However, the description adds nothing — it does not say what is copied from the source plugin, whether tags/config are duplicated, or how the new plugin is identified.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
