Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already mark this as a mutating, non-idempotent operation, and the description adds meaningful context: it relays to the public bid gate, the server holds no keys/funds, it is free with a valid signature, and the outcome is later visible through work_status/my_work. This goes well beyond what the annotations state.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
