Predicate Systems Demos

Name: Predicate Runtime SDK
Rating: 4.8 (50 reviews)
Author: Predicate Systems

Two SDKs to secure AI agent loops: Predicate Authority for pre-execution authorization, and Predicate Runtime for post-execution verification. Keep your agents deterministic and safe.

Demos

Pre-Execution Authorization in Action

See how Predicate Authority blocks unauthorized actions at runtime—before they execute.

Zero-Trust OpenClaw Agent Loop

Pre-execution gate blocks unauthorized writes • Post-execution predicates verify DOM state • Cloud tracing with screenshots
