Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full behavioral burden, yet it only states the return meaning. It does not disclose that this is a non-mutating read, what happens with an invalid or unknown workflow_id, or whether the result is a boolean vs status string.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
