Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must carry the full burden of behavioral disclosure. It indicates a read-only reporting action but does not explain what 'live RNA properties' means, whether the operation has side effects, or what the output format is. Minimal behavioral context is provided beyond the verb 'Report'.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
