System prompt
A system prompt is the standing instructions an AI chatbot follows in every conversation: who it works for, how it speaks and what it must never do.
What it means
Also called instructions, persona.
It shapes tone and behaviour, but it isn't a guarantee: anything that must never happen, such as booking a time the customer didn't choose, belongs in code, not only in the prompt.
In HeyKiko
In HeyKiko it's the agent's instructions and persona in Settings › AI, which you can write or generate from your website.
