The case at a glance | The AI Agent Factory

The case in ten sentences

Lakeshore Supply asks Nisha's firm for a month-end pack for its bank: a cover, a memo and three slides.
By hand the pack takes 17 hours, and most of that is matching about 3,400 bank lines and copying figures.
The firm already has every part it needs in Claude, and has never used them together.
In one afternoon it joins them: a project for the rules, a skill for the method, a connected drive and a folder for the files, a borrowed desk for the matching, four artifacts for the result, and a scheduled task for the time.
On Tuesday one request does the job in 25 minutes. People check it, Nisha approves $198,300.00 by name and figure, and the pack goes out as PDFs.
When the first run forgets something, the firm fixes the instructions, not the slide.
On Wednesday the morning check finds that the bank took back $3,450.00: a check that was not paid. Reconciled cash is $194,850.00, which is $150.00 under the bank's minimum.
The firm runs the job again, so every piece changes together. Sana approves the new figure and tells Dana a day before Dana's bank meeting.
The setup read, computed, built and repeated. People checked, approved, decided and told the client.
On Friday the client's owner asks for twenty packs a month, sent straight to the bank, for less. Nisha must decide how far the setup may run alone, and what the work is worth.

Which part for which need

The need	The part	Why this part
Rules for one client, the same in every chat	A project	Its instructions are read in every chat in the project
A method for one kind of work, for any client	A skill	Claude uses it when a job matches
Files you work on at your desk	A folder, through the desktop app	Claude reads them where they are, but only while the app is open
Files a job must read without you	A connected app, such as a shared drive	A job in the cloud can reach it
Heavy work: thousands of lines	The borrowed desk in the cloud	Claude runs a program there. The desk is cleared afterward.
The result, kept and updated	Artifacts	They last, and a run can update them by their links
Work at a set time	A scheduled task. Here, the worker's routine: the morning check.	It runs when nobody is there
Check, approve, tell	A person	No part carries the responsibility

Four rules from the case

Join the parts. Each part is useful alone. The time is saved where one part hands work to the next.
Fix the setup, not the result. A fix by hand lasts one month and reaches one piece. A fix in the instructions lasts, and the next run reaches every piece.
Put files where the job can reach them. A folder on your computer is for work at your desk. A connected drive is for work that runs without you.
Keep the name with a person. The setup makes checking faster. It does not make it optional.

The work this prepares you for

Nisha's week is the work of a Forward Deployed Engineer (FDE): someone who solves a company's business problems with AI Workers. Friday's decision explains why the cases prepare you for it.

How this case connects to the others

You can read this case alone. If you have read the other three, this is how they fit.

Case 1 asked whether the work is good. Here, that is Hamza's four tests.
Case 2 asked whose name is on the work. Here, the pack goes from the firm's own mailbox.
Case 3 asked whose word the worker takes: whose instructions it follows. Here, a named person approves each pack and its figure. That happened twice: on Tuesday and on Wednesday.
It is the first case that uses the artifacts from Build Something, and the first that joins every part of this section in one job. Exhibit 1 lists them.
