Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds that the response includes both workflow details and steps, which is useful since there is no output schema, but it says nothing about behavior for a missing/invalid ID or what 'details' comprises.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
