Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already cover the safety profile (readOnlyHint, idempotentHint, openWorldHint, destructiveHint=false), so the bar is lower. The description adds useful context about return content — workflows paired with search queries for finding public examples — but says nothing about output format, ordering, or scope limits. This is a modest contribution beyond the annotations, not a rich one.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
