Lab: from messy thread to reply and task list

Put the whole course to work. Turn a tangled customer thread into a reply and a task list, then find the one error Claude planted.

The job

Here is the kind of thread every small business gets: a customer, three replies, two changed minds and a question buried in the middle. Your job is to turn it into one clear reply and a short task list for your team, using Claude, and then to catch the mistake in Claude’s draft before it goes anywhere.

Work through the lab with real Claude open if you can. The assessment at the end of the course gives you a thread of this kind and a draft to critique.

The thread

Read this once, as you would on your phone.


From: Priya Nair (customer) Subject: Re: Re: Re: Patio furniture order

Hi, sorry for all the back and forth. To confirm: we want the 6-seat teak set, not the 4-seat, and delivery to the Oak Street address, not the shop. Can it come on the 14th? Also, does the price include the cushions? Earlier you said 1,840 for the 4-seat; what is the 6-seat?

Earlier, from you: The 4-seat set is 1,840 including delivery within 20 miles. Cushions are a separate 220 for the set.

Earlier, from Priya: Actually let’s do the 4-seat. Deliver to the shop on the 12th please.

Earlier, from Priya: Hi, interested in the teak set you posted. Price and delivery?


Notice what a reader has to untangle: the set changed, the address changed, the date changed, and there are two live questions (price of the 6-seat, and cushions). Nowhere does the thread give the 6-seat price.

Step 1: brief Claude properly

A weak prompt: “Reply to this.”

A strong prompt uses lesson 2:

“You are the office coordinator at a small outdoor furniture shop. Below is a customer thread. Write a reply to Priya that confirms exactly what she has asked for, answers both of her questions, and asks for anything we still need. Do not invent prices: where a price is not in the thread, write a placeholder in square brackets for me to fill. Warm, short, no corporate words. Then, under a heading Tasks, list what our team needs to do, one line each with an owner left blank.”

Paste the thread (names are fine here if you are on an approved work account; otherwise swap “Priya Nair” for “the customer” and remove the address).

Step 2: read the draft against the thread

Suppose Claude returns this:

Hi Priya, no problem at all. Confirming the 6-seat teak set, delivered to your Oak Street address on Friday the 14th. The 6-seat set is 2,460 including delivery. Cushions are included at no extra charge. Could you confirm someone will be home between 9 and 1? Thanks, Sam

Tasks

  • Update order to 6-seat teak set
  • Change delivery address to Oak Street
  • Schedule delivery for the 14th
  • Confirm delivery window with customer

Run the two-minute check from lesson 6:

  • Numbers and names. The 6-seat price, 2,460, is not in the thread. We said to use a placeholder. This is an invented figure.
  • Count the asks. Price of the 6-seat: answered, wrongly. Cushions: answered, and wrongly. The thread says cushions are a separate 220, not included.
  • Hunt for the invention. “Friday the 14th”: the thread never says which weekday. Check a calendar before confirming.
  • Missing task. Nobody is tasked with pricing the 6-seat set or checking the 20-mile delivery radius for the new address.

Two planted errors in a friendly, confident draft. Either would have cost money or an awkward call.

The draft with every problem marked:

The lab reply draft with four marked problems: an invented 6-seat price, cushions wrongly included, an unverified weekday, and a missing pricing task
A and B are the planted errors. C and D are the kind of thing the check also catches.

Step 3: fix with one follow-up

“Two corrections: cushions are a separate 220, not included. We do not have a 6-seat price in the thread, so use a placeholder and add a task for someone to price it and check that Oak Street is inside our 20-mile delivery area. Remove the weekday from the date.”

The second draft is right. Total time: about four minutes.

Try it now

Find a real thread from your own inbox with at least three replies. Brief Claude with the strong prompt pattern above (redacting as needed), then run the two-minute check on the result. Write down every fix you had to make.

Remember: a good brief tells Claude what it must not invent. A good check compares every number against the source and counts the asks. The draft is never finished until you have done both.
