Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full behavioral burden and does not state whether this is a read-only operation, whether it requires an active Studio bridge, what 'recent' means, or how much log history is returned. 'Captured by the plugin' hints at the source but not the connection/auth requirements.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
