OpenAPPA is an open-source, vendor-agnostic, deterministic AI guardrail engine designed to enforce information-flow policies for large language model agents. It prevents data exfiltration via prompt injections or hallucinations without breaking agent functionality, using a declarative configuration to track and restrict data flows across tools and actions.
