Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden, but it only says 'show', which suggests a read-only operation but doesn't explicitly disclose safety (e.g., no side effects, no data mutation). It also doesn't mention whether authentication is required, any rate limits, or the response format. For a status tool, it would be helpful to state it's non-destructive and safe to call.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
