Guardrails

Guardrails are the checks placed around a model's input and output — content filters, schema validation, permission scoping, human-approval gates — that keep an LLM or agent inside acceptable bounds in production. They matter most for agents with real tool access, where an ungrounded or manipulated response can translate directly into an unwanted action, not just a bad chat reply. Guardrails are a design layer added deliberately, not a property models come with by default.
