Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It states 'search' but doesn't disclose behavioral traits: whether it's read-only (likely, but not confirmed), if it requires authentication, error handling (e.g., invalid codes), or response format. The description adds minimal context beyond the basic action, leaving gaps in understanding how the tool behaves.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
