Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations declare readOnlyHint=true and openWorldHint=false, so the safety profile is already covered. The description adds real value beyond them by disclosing what the payload contains (requirements, bid bond, submission place/time, original link), which helps the agent decide to fetch full text rather than a summary.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
