System Prompt

Hidden instructions given to an AI model before a conversation starts, setting its behavior, tone, or constraints, distinct from what the end user types.

Think of it like

Like the standing instructions given to a new employee on day one ('always greet customers formally') that shape how they behave in every conversation after.

Junior or senior?

Junior sounds like

Wrote a system prompt once and forgot about it.

Senior sounds like

Treats it as something to version and test, and can describe how they tested a change to it.

Ask them

“How did you test whether a change to your system prompt actually improved things, versus just feeling different?”
