Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=false, and openWorldHint=true, which conveys that this is a non-idempotent write with external reach. The description adds nothing on top of that: no mention of required permissions, what the request body should contain, or what happens on repeat calls. There is no contradiction with the annotations, but zero value added beyond them.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
