OpenScript

A policy pipeline that sits between an application and its LLM agent, and refuses to pass along the things that should not go through. This page runs the real package — compiled to WebAssembly, in your browser.

Downloads a Python runtime and the OpenScript package into this tab. Roughly 7 MB, once.

Nine built-in policies, no network calls: prompt injection, toxicity, harmful requests, PII, secrets, compliance, tool firewall, output schema and audit logging. The demo exercises seven of them plus the audit trail.
