Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already mark this as read-only and non-destructive, and the description adds useful behavioral details beyond that: the document is rendered as markdown, comment IDs are stable, and attorney redlines come as structured suggested changes. It does not mention error cases or prerequisites, but none are critical for a simple read operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
