Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden for behavioral disclosure. It conveys the core behavior (showing active plugins with potential performance impact) and hints that the impact is an estimate via 'potentiellen', but it does not disclose whether the tool is read-only, how impact is calculated, or what the output format looks like. This is minimal beyond the bare function.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
