Demos

Predicate Systems Demos

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.

Secure Agents with Runtime Authorization

Predicate-Authority: zero-trust runtime authorization to protect AI agents from prompt injection and unauthorized tool calls before execution.

Temporal.io Integration

OpenClaw Predicate Provider

Browser Agent Demos

Reproducible browser agent demos using structure-first snapshots and Jest-style assertions.

Hacker News

"Open the top Show HN post"

Demonstrates ordinal reasoning ("first", "top") using semantic geometry. The agent identifies ranked items without screenshots.
