Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden for behavioral disclosure. It only mentions the source table, but does not describe what happens if the option does not exist, whether the return value is raw or unserialized, or any side effects. For a read tool, this is a moderate gap but still insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
