Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the behavioral burden. It does add useful context with 'ACL-visible,' indicating access-control filtering applies. It does not disclose behaviors like not-found handling or permission requirements, but for a simple read operation this is a reasonable minimal disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
