Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It transparently reveals that the response may contain notices like 'in Planung', 'auf Anfrage', or 'kein Termin ausgeschrieben', and uses a non-mutating verb, but it does not state side-effect-free behavior, error handling, or permissions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
