Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. 'Generate types' implies a creation or output operation, but the description doesn't disclose what 'types' refer to (e.g., TypeScript interfaces, JSON schemas), whether this is a read-only or mutating operation, what permissions are needed, or what the output format is. It lacks behavioral context beyond the basic action.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
