Claude Code / generic first win

Make a useful document from a rough one.

Begin with two fictional text files. Ask for a welcome note you can open, question, and revise.

Cost: The kits and practice files are free. Claude Pro includes Claude Code: $20/month billed monthly, or $17/month with annual billing ($200 up front) (as of 2026-10-08). API billing is pay-per-use. OMP cost depends on the model provider you connect.

Your first win, on fictional files

Download both fictional files first. They are free and work without a ZIP on Mac, Windows, and Linux.

1 / INPUT · draft-sample.txt

Our best-in-class membership delivers guaranteed savings and effortless grocery delivery.

The brief says: The current welcome is a receipt and a fridge magnet.

2 / EXACT REQUEST

Read brief-sample.txt and draft-sample.txt in this folder. Replace vague claims with a short welcome note for new members using only the brief. Save it as revised-draft.txt. Do not edit the inputs. After saving, say which draft claims lacked support.

3 / SAVED OUTPUT · revised-draft.txt

Welcome to Riverbend Co-op

Welcome, and thank you for joining Riverbend Co-op, your neighborhood grocery co-op. As a member, you're an owner here, not just a shopper.

To get started, join us for a Saturday morning orientation. Staff will show you around and walk you through how to suggest products you'd like to see on our shelves.

We're glad you're here.

Example outcome, recorded 2026-10-08 with Claude Code 2.1.292. Your result may differ.

Human check: The saved note says staff will show members around. Does the brief say that? Remove the extra claim before using the note.

Your first time in a terminal

Use a computer for this part. Choose Claude Code for the optional Mac kits or OMP for the plain-text practice path. Install only your chosen tool. Nothing is uploaded to this site.

Both practice-file downloads are directly above the example.

Make a folder called cli-practice inside Downloads, then put both fictional files in it. Leave the originals unchanged. Then choose your computer below.

Mac: Terminal and Finder

Install Claude Code (official setup) or OMP (official quickstart). Read the install instructions before running a command.
Open Terminal using Command + Space, type Terminal, and press Return. Type cd with a space after cd. Drag your cli-practice folder from Finder into Terminal, then press Return. Apple's folder-drag guide.
Type claude or omp and press Return. On its first run, Claude Code asks you to sign in in your browser; OMP asks you to set up a model provider.
Copy the EXACT REQUEST above, paste it into your agent, and press Return. Read any requested file permissions before approving them.
In Finder, open cli-practice and double-click revised-draft.txt to read it. Compare it with brief-sample.txt; do not trust the result without checking.

Windows: File Explorer and PowerShell

Install Claude Code (official Windows setup) or OMP (official quickstart) using the PowerShell command, not a Mac .command file.
In File Explorer, right-click cli-practice and choose Open in Terminal on Windows 11. It opens in that folder. If this option is missing, open PowerShell, type cd , paste the folder's full path in quotes, and press Enter. Microsoft's Terminal context-menu support.
Type claude or omp and press Enter. On its first run, Claude Code asks you to sign in in your browser; OMP asks you to set up a model provider.
Copy the EXACT REQUEST above, paste it into your agent, and press Enter. Review file-access prompts before approval.
Open cli-practice in File Explorer and double-click revised-draft.txt. Read it and check every claim against brief-sample.txt.

Linux: Terminal and Files

Install Claude Code (official Linux setup) or OMP (official quickstart). Use the terminal install command for your chosen tool.
Open Terminal (Ctrl + Alt + T on most distributions). Type cd ~/Downloads/cli-practice and press Enter. If you saved the folder elsewhere, replace the path with its location. In KDE Dolphin, opening the folder and pressing Shift + F4 also opens a terminal there. KDE's folder-terminal guide.
Type claude or omp and press Enter. On its first run, Claude Code asks you to sign in in your browser; OMP asks you to set up a model provider.
Paste the EXACT REQUEST above and press Enter. Review access prompts before approving.
Open cli-practice in Files and open revised-draft.txt in a text editor. Compare it with brief-sample.txt.

If a command is not found, use the linked official install troubleshooting. For a slower walkthrough, see the Claude Code terminal guide and OMP quickstart. The same two plain-text files work in either lane; the four Mac ZIP kits are Claude Code only.

One next move

Open the saved file and identify a sentence to improve. Ask for a second version saved as a new file, without changing either original. Pick one tedious document you own. Make a copy before asking for a rewrite.

Follow the shared four-step ladder: first file, second version, skill, separate review.

Want the ready-made Claude Code kit?

The ZIP has a Mac installer, six Claude Code commands, two skills, a guide, and editable memory. The plain-text task above works without a ZIP on Mac, Windows, or Linux. This kit has not been adapted to OMP.

More to try

Draft from rough notes

Read brief-sample.txt (it came with the kit). Turn it into a clean one-page document: lead with the reader's problem, name the outcome, cut the filler. Save it as draft.txt.

Sharpen a flat paragraph

Read draft-sample.txt. It is deliberately flat and full of filler. Rewrite it tighter: lead with the stakes, cut the slop, keep it under 120 words. Then tell me in one line what you changed.

Prep for a call

I have a call with Acme Co in an hour. Search the web and give me one page: what they do, what is pressuring them now, the smartest thing to lead with, and three questions to ask.

Your challenge

When you choose your own material, use only files you are allowed to share. Check every saved output yourself.
