 It is important to ensure that content generated by agentic systems respects intellectual property rights and avoids the unauthorized use of copyrighted material. Copyright compliance is essential not only for legal and ethical reasons but also to protect users and organizations from liability and reputational risk.
 
+!!! danger "Copyright Risks"
+    Agents that generate code or other copyrighted material without proper authorization are at risk of violating copyright laws. This could expose your agentic system to legal liability:
+    
+    * You agent may handle, process and reproduce copyrighted material without permission
+    
+    * You may unknowingly host copyrighted material without permission
+    
+    * You may unknowingly expose copyrighted material to users

 Guardrails provides the `copyright` function to detect if any licenses are present in a given piece of text, to protect against exactly this.
