Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description indicates a read-only operation ('Get'), but lacks details on error handling (e.g., missing table), authentication needs, or what exactly constitutes 'structure' (columns, types, constraints?). With no annotations, the description carries the full burden, which is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
