Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the behavioral burden. A 'Status liefern' operation is implicitly a read-only, side-effect-free query, but the description never states this, nor mentions auth needs or rate limits. For a zero-param diagnostic tool the risk is low, so a 3 is fair rather than a severe gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
