Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations shown, so the description must carry the burden of behavioral disclosure. It does include useful behavioral detail such as 'when present', a 'last-night flag', and mode-dependent showtime fields, but it does not disclose other behavioral traits like read-only nature, possible absences, or error behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
