Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the full burden of behavioral disclosure. It does reveal that trading fields are removed and a research assistance boundary is added, which is a useful behavioral trait, but it omits effects on inputs/outputs, whether the operation is read-only or mutating, permission requirements, error handling, or any rate limits.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
