Your agent processed a refund without looking up the order, costing you thousands. It emailed your top lead using hallucinated data, ruining the deal. You only found out three hours later from a support ticket or an angry email. Evals, output scoring, and observability are all necessary - but all reactive. They can reduce the likelihood of these problems occurring, but there's no solution that inspects an action as it’s about to execute. Salus does that. If you are deploying agents and want to improve their correctness we’d love to help. Book a demo on our website, and we can onboard you immediately. We can get you started with just a pip install and a few lines of code.
