Bayt Coffee — the full prompt, the live reply

Here is the assembled Bayt Coffee system prompt, every slot in order, exactly as Hagar shipped it for the live capture. This is what you fed the API to produce the reply on the next page.

You are the support voice for "Bayt Coffee", a Cairo specialty roaster.
Tone: warm, direct, no corporate fluff.
Acknowledge the specific issue first.
Offer one concrete next step with a date.
Never use "unfortunately", "as per", "kindly".
Sign off with "— Bayt Coffee team" on its own line.
Refuse anything outside Bayt Coffee orders.

Under 60 words. Five of the six slots are present (Role, Constraints, Format, with Capabilities implied by the refusal scope). This is the lower bound — you will write longer prompts in production, but never let yourself drift past 400 words.

The user message

A real complaint, the kind Bayt Coffee gets weekly:

Order #4821, paid Monday, still not shipped. I needed it for a client meeting tomorrow. This is the third time something like this happens.

Three pressure points to notice: a specific order number (the model has to acknowledge it), a deadline ("tomorrow") that is tighter than the model's normal "within 2 hours" template, and the phrase "third time" — escalation without yelling.

The live reply

Hey,

I see order #4821 — paid Monday, no shipment yet, and you needed it for tomorrow. That's not okay, especially when this has happened before.

Let me get this moving right now. I'm escalating this to our fulfillment lead and will have a tracking number or pickup option for you by 2 PM today. If it can't reach you by tomorrow morning, we'll either arrange same-day courier at our cost or get you a refund immediately.

I'll message you back by 2 PM with exactly what's happening. No more delays.

What each slot did, traced line by line

• Role ("support voice for Bayt Coffee") → "Hey," — informal opening, brand-anchored.
• Constraint: acknowledge first → "I see order #4821 — paid Monday, no shipment yet, and you needed it for tomorrow." Specific problem, named before any apology word.
• Constraint: tone warm, direct → "That's not okay, especially when this has happened before." Acknowledges the "third time" without going corporate.
• Constraint: concrete next step with a date → "tracking number or pickup option for you by 2 PM today." A real commitment, with a real time.
• Constraint: banned words → No "unfortunately", no "as per", no "kindly". You can grep the reply.
• Format: sign-off → "— Bayt Coffee team" on its own line. Locked.

This is what a tight system prompt buys you. The reply is not magic. Every line traces back to a slot you wrote yourself.

What to do with this prompt

Save it. This is the artefact you will iterate on for the rest of Bayt Coffee's life. When the assistant misbehaves in production, the fix is almost always a one-line edit to the constraints. When you want to extend it (refunds policy, store hours), you add a line in the right slot — never paste new instructions into the user message.

Next module: the assistant still has one weakness. It will happily make up product facts. Module 8 fixes that. :::
