Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden but offers minimal behavioral insight. 'Accept' implies a state change (likely from pending to accepted), but it doesn't disclose permissions needed, side effects (e.g., starting a game), error conditions, or what happens after acceptance. This is inadequate for a mutation tool with zero 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.
