Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already declare readOnlyHint=true, which establishes the tool as non-mutating. The description reinforces this with the GET endpoint, but it does not disclose behavior on edge cases like invalid or non-existent ids. Given the read-only annotation, the description adds acceptable but minimal behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
