System Message

Definitions

1. A high-priority instruction message used to define the assistant's role, rules, or behavior before user input is considered. System messages are often used to enforce boundaries and establish response style or workflow constraints.

   In plain English: A high-priority instruction that sets how the AI assistant should behave.

   Example: "The bug came from a missing system message that normally told the assistant to answer only from retrieved policy text."
