Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Despite having only a task_id parameter, the description discloses a real side effect: active analyses are refreshed and their status and findings saved in Lightbringer, which explains the non-read-only hint. It also explains that findings_error marks unavailable findings without altering terminal execution status, a nuance annotations cannot express. It could go further on whether refresh is throttled or whether repeated calls incur cost.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
