AI agents can return valid JSON and still make the wrong decision. Linden adds a reliability layer that validates AI outputs against schemas, business rules, and trusted data before they reach downstream systems. Configure your requirements and get clear decisions: ALLOW, HUMAN REVIEW, or BLOCK. Integrate with an API or Python SDK to add validation to your AI workflows.
