Could you build this?
Partial The UI and payment-agent demo are vibe-codeable, but reliable prefill-time prompt injection filtering needs security and ML expertise and rigorous evaluation.
What it would actually take: The core is a classifier or detection pipeline for injected instructions, plus policy enforcement that gates tool calls before the model acts. Reliable detection needs a labeled adversarial dataset, benchmark evaluation against attack suites, and security researchers to test for bypasses.
