Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. While 'Returns' implies a read-only operation, it doesn't specify whether this is a real-time query, cached data, requires authentication, has rate limits, or what format the tally results take. For a governance tool, these behavioral aspects are important but undocumented.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
