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 discloses the backing file (prismlauncher.cfg) and that reads are section-scoped, but says nothing about what happens with an unknown section, whether defaults are returned, or what the response looks like — and since 'section' is optional (0 required params), the no-argument behavior is left undefined.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
