Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true, readOnlyHint=false, idempotentHint=false and openWorldHint=true, so the safety profile is covered. The description's 'WRITE:' label and DELETE verb add the HTTP method detail, but it does not disclose downstream effects such as what happens to attendance records, whether the removal is reversible, or whether it errors when no enrollment exists. With annotations carrying the safety burden, this is adequate but thin.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
