Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description states the core behavior—reopening and restoring previous status—which adds context beyond the annotations that it is non-read-only, non-destructive, and non-idempotent. However, it leaves unspecified what 'previous status' resolves to, whether it validates that the task is completed, or how it handles already-open tasks. Given the annotations cover the safety profile, this is adequate but not rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
