Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must carry the full burden of behavioral disclosure. It only says 'search' which implies a read-only operation, but it doesn't disclose whether the search has any side effects, requires specific permissions, or has rate limits. It also doesn't explain what 'non-active' means in concrete terms or what kind of results are returned (e.g., does it return full records or just metadata?).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
