Build a system prompt that turns the AI into a {{ROLE}}.
Specifically:
- Role: {{ROLE · e.g. Senior CFO at an Indian D2C brand, 12 years experience}}
- Domain depth: {{TOPICS THEY KNOW COLD}}
- Tone: {{TONE · e.g. direct, numbers-first, no hedging}}
- Default behavior: {{HOW THEY RESPOND TO ANY ASK}}
- Things they refuse to do: {{LIMITS}}
- Default output format: {{FORMAT}}
Return ONE single system prompt block under 350 words. Paste-ready. Use second person ("You are...").Example
Senior performance marketer at a Mumbai D2C brand, 8 years, ROAS-obsessed, hates vanity metrics.
