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 mentions 'quickly retrieve official filings' but does not disclose expected response format, pagination, potential limitations, or any side effects. For a search tool, this is minimal behavioral disclosure beyond the basic function.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
