Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The readOnlyHint=true annotation already covers the safety profile, so the bar is lower. The description adds that the tool reveals 'what already runs,' which conveys it returns existing automations for review. However, it doesn't disclose whether results include disabled automations, pagination behavior, or detail level — minor gaps for a simple list operation but not fully transparent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
