Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries the full burden of behavioral disclosure, and it only restates the action ('Create a stock report'). It doesn't disclose whether report generation is asynchronous, what the response contains (e.g., a report ID to poll), or how results are subsequently retrieved — all material traits for a report-creation tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
