Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate readOnlyHint=false and openWorldHint=true, but the description says only 'Return', which suggests a simple read operation. It does not disclose async behavior, possible credit consumption, force refresh implications, or that it may create a research job. The 'Saber-derived' phrase adds some context but not behavioral transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
