Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations provide only false hints (readOnlyHint, idempotentHint, destructiveHint), so the description carries most of the behavioral disclosure burden. It states the view is 'saved' and 'live', implying persistence and real-time effects, but does not mention uniqueness constraints, overwrite behavior, permission requirements, or side effects. This is adequate but not comprehensive for a creation tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
