Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and openWorldHint, so the safety profile is covered. The description adds nothing beyond that — no pagination behavior, no scoping rules, and 'all tasks' is mildly misleading given an optional parentId filter. With annotations carrying the load, the description still contributes almost no behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
