# 4. The System Prompt — Programming Behavior

In Section 3 we saw that the model receives a list of messages with roles. The system prompt is the first message in that list — written not by you, but by whoever built the product. It steers how the model behaves before you say a word, and it's where tool definitions, guardrails, and safety constraints live.

when to use it

Community prompt sourced from the open-source GitHub repo ymyke/aiaiai (CC-BY-SA-4.0). A "System Prompt" style prompt — adapt the placeholders and specifics to your task. Imported as-is and not independently retested here, so check the output before relying on it.
