Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so description must fully disclose behavior. It only states 'Find events at a specific location' without details on scope (e.g., date range, event types), authorization needs, or side effects (e.g., read-only). This is insufficient for a tool with no annotation coverage.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
