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 '启用或禁用' (enable or disable) implies a state change operation, the description doesn't disclose what the proxy does, what gets affected, whether this requires special permissions, or what the expected behavior is. For a state-changing tool with zero annotation coverage, this 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.
