Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden and it does disclose real behavior: the precondition (job must be claimed) and the payment outcome (auto-verified jobs pay instantly). It omits however what happens to non-auto-verified submissions, failure handling, and whether submission is final or reversible.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
