Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full responsibility for behavioral disclosure. 'Search for teams' reveals nothing about whether this is a read-only operation, what permissions are required, whether it's paginated, rate-limited, or what the response format might be. For a search tool with zero annotation coverage, this is completely inadequate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
