4 Layers of AI Agent Guardrails to Contain Agent Risk

Description and use

<h1> 4 Layers of AI Agent Guardrails to Contain Agent Risk </h1> <p>Your agent doesn't need a smarter model. It needs containment.</p> <p>No single filter stops prompt injection — OWASP lists it in its Top 10 for LLM applications and notes it's unclear whether foolproof prevention even exists. So the goal isn't a perfect wall. It's layered defense: when something slips through, the blast radius stays small and a human is in the loop exactly where it counts.</p> <h2> Layer 1 — Input guardrails: keep poison out </h2> <ul> <li>Validate and sanitize everything before inference: schemas, length lim
