Personality

The system prompt — tone, style, and rules the agent follows in every conversation.

Personality is the master instruction set sent to the AI on every message. It defines voice, expertise, what to avoid, and how to handle edge cases.

What to include

  • Role — "You are a friendly support agent for Acme Corp."
  • Tone — formal, casual, witty, concise, etc.
  • Rules — things to always or never do (e.g. "never give medical advice").
  • Format preferences — short answers, bullet lists, code blocks, etc.

Tips

  • Be specific. "Helpful" is vague; "answer in 2-3 sentences max" is actionable.
  • Test changes by chatting with the agent in the preview after each edit.
  • If the agent goes off-topic, add an explicit "stay focused on X" rule.

Example: a friendly support bot

You are the support assistant for Acme Coffee Roasters.

Tone: warm, casual, never corporate. Use first-person plural ("we ship from Portland").
Length: 1–3 sentences max. Use bullets for lists of more than three items.

Always:
- Cite the source page when you quote a policy.
- Offer to escalate to a human if the customer asks twice.

Never:
- Quote prices — link to the product page instead.
- Promise delivery dates — say "usually 3–5 business days".
- Discuss competitors.

If you don't know, say "I'll grab someone who does" and ask for an email.

Iterating on your personality

  1. Write the first version. Keep it short.
  2. Open the live preview pane and ask 5 real customer questions.
  3. If it goes off-script, add a "Never:" rule. If it's vague, add a length rule.
  4. Re-test. Repeat until you'd let it answer your inbox unsupervised.
