What to ask before you hire
Which tools will the agent call, how failures are caught, how accuracy is measured before launch (an eval set built from your real inputs), what each run costs in model fees, and who can see the logs.
Agency or freelancer?
For a single prompt-and-API integration a freelancer is often enough. For agents touching customer data or several systems, an agency gives you design, testing and someone on call.
