Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. 'Get' implies a read operation, but the description doesn't specify whether this requires authentication, has rate limits, returns paginated results, or has any side effects. It doesn't describe what format the properties are returned in or whether archived companies are included by default. For a read tool with zero annotation coverage, this is insufficient behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
