Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description bears full responsibility for behavioral disclosure. It merely restates that it gets all available block patterns without detailing what 'available' means (e.g., from themes, plugins, or block directory), return format, pagination, or any authentication requirements. This is minimal disclosure beyond the basic operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
