Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already declare readOnlyHint=false (write), idempotentHint=true, and destructiveHint=false, covering key behavioral traits. The description adds context that the tool only accepts bounded structured specs and rejects binary bytes, which is useful for an agent deciding whether to call it. It does not, however, describe side effects, validation behavior, or error conditions, but with annotations carrying safety/idempotency, this is a moderate contribution.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
