Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already declare readOnlyHint, idempotentHint, and destructiveHint false, covering the safety profile. The description adds minor behavioral context: the scope is limited to 'the user's projects' and the status filter. It does not disclose pagination, sorting, or other behavior, but for a simple read-only listing this is acceptable.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
