Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. 'Get all properties' implies a read-only operation, but it doesn't disclose whether this requires authentication, has rate limits, returns paginated results, or what format the properties come in. For a tool with no annotation coverage, this is insufficient behavioral disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
