Guardrails I use when AI touches a real product

The moment AI starts affecting a real workflow, guardrails stop being optional. The right controls depend on the risk profile, but the same pattern appears often: constrain inputs, shape outputs, and review the behavior over time.

Guardrails are not only safety filters. They also include typed schemas, fallback responses, evaluation fixtures, and human review triggers.

The controls that matter most

• Schema validation for model outputs.
• Simple regression checks against known examples.
• Clear fallback behavior when the model is uncertain.
• Logging that makes production behavior explainable.

That combination usually beats a more ambitious control framework that no one can maintain.
