Prompt

A prompt is the instruction a language model receives — it defines role, tone, allowed actions, and provides the context for the response.

Also known as: System Prompt

In detail

Prompts are business logic in text form. We treat them like code: versioned in Git, with tests, reviews, and canary rollouts.

A good system prompt defines:

  • Who is the agent (persona, tone)?
  • What's allowed, what isn't?
  • Which tools are available?
  • What happens on uncertainty (escalation)?
  • Examples of desired behaviour
