Stop your AI agents from doing stupid things (I open-sourced a React UI for Human-in-the-Loop)

If you are building AI applications right now, you’ve probably hit the exact same wall I did: giving AI agents access to real-world tools is terrifying. When an agent is just summarizing text, hallucinations are annoying. When an agent has the tool-call ability to delete_invoice or refund_customer, a hallucination is a catastrophic business failure. Backend frameworks like LangGraph and CopilotKit are great at handling the "pause" state for Human-in-the-Loop (HITL) workflows. But they leave the frontend completely up to you.
