Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description states only that it updates width, implying mutation, but with no annotations, it fails to disclose side effects, permissions needed, range constraints, or whether it triggers DRC updates. The description adds minimal behavioral context beyond the action itself.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
