How do I govern agent steps from AI agents in a healthcare environment?

Route agent steps through Kastra. The Kastra proxy or SDK intercepts each step before it executes, evaluates ABAC policy against the request attributes, environment, principal identity, and risk signals, and returns an allow, deny, redact, or human-approval decision. Healthcare customers map controls directly to HIPAA, HITRUST, GDPR, 21 CFR Part 11.
