Guardrails That Log Violations After the Fact Are Just Dashboards

FastAIAgent guardrails block before the provider ever sees the data. Define one in code, or author it once on the Control Plane and every connected agent enforces it.

Guardrails that log violations after the fact are just dashboards.

FastAIAgent guardrails block — before the provider ever sees the data. Define it in code, or author it once on the FastAIAgent Control Plane and every connected agent enforces it.

Blocked, and tied to the trace

The guardrail span shows exactly where the run stopped: no_pii BLOCKED, with credit_card, email and ssn detected in the agent input.

The blocked run is not a separate alert to go and correlate later. The guardrail is a span on the trace, so the record of what was stopped sits with the record of what the agent was doing at the time.

More: the SDK on GitHub and the documentation. The longer argument is in Guardrails that actually block, and the platform view is on the Enterprise page.
