Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries the burden. It discloses data content and term count but not how results are returned (e.g., term start/end dates, JSON shape) or whether output covers future years beyond the default. The 'public school' qualifier and 4-terms-per-year detail add some useful context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
