Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and destructiveHint=false, and the description's 'Read' aligns with that. It adds useful context about what status aspects are covered (progress, failed tasks, interruption state), but it does not disclose error behavior, job lifetime, or whether results are valid only while a download is active. No contradiction with annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
