Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description mentions governance filters and sanitization, which adds context beyond the annotations (readOnlyHint=false, openWorldHint=false). The description does not contradict annotations. However, it does not detail what the governance filters do, how sanitization works, or what side effects occur (e.g., does it actually save anything or just extract?). The return value details are covered by the output schema.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
