- For
- AI-agent developers needing privacy-preserving action checks
- Worth noticing
- The site says model-based checks are attested, not proven, and excludes agent traffic that bypasses its proxy.
Field notes
The described flow places a proxy between an agent and its tools, checks calls locally, and generates a one-time attestation for verification. The page lists the policy-root hash, detector version, action hash, expiry, and nullifier as public fields. It limits its claim: model-based layers are attested rather than proven, and calls that do not pass through the proxy are not covered.
