Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true, readOnlyHint=false and openWorldHint=true, so the safety profile is covered by structured data. The description adds nothing beyond that: it does not say whether deletion is permanent or recoverable, nor what happens to the parent task box, nor what the frameId scoping implies.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
