Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the behavioral disclosure burden. It discloses an authorization prerequisite (Sorqen key) and the nature of the data (context, not market feed), which is meaningful. It does not describe return format, side effects, or error behavior, but for a zero-parameter lookup this is a modest gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
