Hi everyone.TypeSafe released Jev last week, and it pushed me to build agent-chaperone. It is a screening layer for AI agent tool calls and tool results.It screens risky, off-task, or secret-leaking actions before they run, and prompt injections or other suspicious instructions before the agent reads them.Repo: https://github.com/agent-chaperone/agent-chaperoneWebsite: https://agentchaperone.dev/
