The run

One request

New words on this page. Timing item: money on its way, such as a check the bank has not paid yet. It sorts itself out in a few days. Approval: a named person's written yes, which names the pack and its figure. Export: to save a copy of an artifact as an ordinary file, such as a PDF.

On Tuesday, October 5, at 10:05 a.m., Hamza opened a new chat in the Lakeshore project and typed one request.

"Prepare the September 2027 month-end pack."

That was all. The rest was already in the setup: the project's instructions told Claude where the files were, what to build and what never to do. Sana's skill told it how to write the memo.

What Claude did

Claude said what it was doing as it worked (Exhibit 5).

1. It read the files. September's bank lines and the ledger, from the shared drive: 3,395 bank lines and 3,404 ledger lines. The bank file was the one the worker had downloaded on Friday, October 1.
2. It matched them, with a program. It wrote a small program and ran it on its borrowed desk in the cloud. The program paired each bank line with a ledger line of the same amount, a date no more than five days apart, and the same name or check number where there was one. It matched 3,395 pairs. It listed two pairs under Needs a look, because two payments had the same amount on the same day, and Hamza confirmed them by hand. Nine ledger lines had no bank line yet: two payments in (deposits) and seven checks.
3. It worked out the figure.

4. It built the four pieces. It put the lines and the matched list in the sheet. With Sana's skill, it wrote the memo. It filled the three slides and the cover. It used the links in the instructions, so it updated the four pieces that Hamza had made on Monday.
5. It wrote a run note. A few lines, saved to the drive: which files it read, how many lines it matched, the figure, and the four pieces it updated.

It finished at 10:30 a.m. Hamza had not copied a single number.

What people did

Hamza's two days of work were now about two hours of checking, this first time. In a normal month it would be about one hour. He did four tests: checks he does by hand. None of them used Claude.

1. The arithmetic. With a calculator, using the closing balance in Claude's run note: $201,480.00 plus $6,120.00 minus $9,300.00 is $198,300.00.
2. The matching. He chose twenty matched pairs from the sheet at random. He read each pair against the bank's own statement in his folder.
3. The leftovers. He read all nine lines and found each one in Lakeshore's ledger. They were timing items: money on its way, which sorts itself out in a few days.
4. The pieces. He opened the sheet, the memo and slide 2. All three said $198,300.00.

The figure was also the same as the cash in Lakeshore's ledger. So the memo's first line said:

Status: READY. Reconciled cash at September 30, 2027 is $198,300.00, the same as the ledger. 9 timing items. Nothing unrecorded.

It was $3,300.00 above the bank's minimum.

What the first run got wrong

Sana read the pack at 2 p.m. The figures were right. One thing was missing.

"Slide 2 shows our figure. It does not show the bank's minimum beside it. The bank will look for that first."

Hamza reached for the slide. Sana stopped him.

"If you type it into the slide, it is right this month and wrong next month. Put it in the instructions."

He added one sentence to the project's instructions: "Slide 2 shows reconciled cash and the bank's minimum, side by side." Then he asked Claude to prepare the pack again. Six minutes later slide 2 had both figures, and the other pieces had not changed.

Rule to remember: when the result is wrong, fix the setup and run the job again. A fix made by hand lasts one month. A fix in the setup lasts.

Approved and sent

At 4:10 p.m. Nisha wrote in the firm's Slack channel:

"Approved: Lakeshore September month-end pack, reconciled cash $198,300.00."

Hamza exported the cover, the memo and the slides as PDF files.¹ At 4:25 p.m. they went to Dana from reports@. In Cleveland it was 7:25 a.m.

Dana answered within the hour. "This is exactly what the bank asked for. Thank you."

Nisha counted the people's time for the day: Hamza two hours, Sana one hour, herself fifteen minutes. This first time, they had also fixed the setup. In a normal month she expected about two hours in all.
