Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotation readOnlyHint=true already indicates a read-only operation, so the description does not need to restate that. It adds a useful detail: the tool reports the reason for disabled connectors, which is not covered by annotations. However, it does not disclose other behaviors like output format or potential delays. Given the annotation coverage, this is an adequate but not exceptional disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
