Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are supplied, so the description carries the full behavioral burden. It conveys only the state transition (accept, then begin work) and omits whether funds are escrowed or released, whether acceptance is reversible, what permissions are required, and what happens if the order is not yet funded — all material for a money-touching mutation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
