Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden of disclosing behavior. 'Delete (unsubmit)' communicates the mutating action and clarifies that it removes the sitemap submission rather than the hosted file, but it does not mention permissions, side effects on indexed pages, or error/response behavior. It is adequate but leaves gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
