Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the verb 'Show' is the main behavioral signal, indicating a read-only operation. The description does not disclose whether authentication is required, where the config comes from, or what happens if no config exists, but for a zero-parameter display tool this is a tolerable gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
