Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the burden. It discloses a read operation ('Get') with no side effects, but does not elaborate on return format, error behavior, or access requirements. For a simple get-by-ID, this is acceptable but not rich; there is no contradiction with annotations since none exist.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
