Unit 4 Git playground

A tiny command-line notes tool, used as the practice repo for Unit 4 (Git). The app is a safe sandbox for doing real Git work with Claude. The task below is something you run here with Claude; follow the steps and submit the link it asks for.

The app

• node notes.js add <text> — add a note
• node notes.js list — list all notes
• node notes.js delete <id> — delete a note

Layout: notes.js is the entry point, lib/store.js loads and saves notes (in notes.json), and lib/config.js holds app settings.

Set up

1. Make sure you have your own copy of this repo (created from the lesson on the platform).
2. Clone it locally, and run gh auth login so Claude can open pull requests through the gh CLI.
3. Open Claude Code in the cloned folder.

Lesson 1 task — let Claude read your repo

Goal: instead of reading a diff yourself, have Claude tell you what changed, then commit a summary.

1. Make a few small edits across a couple of files — change a line, add a short function, rename a variable. Slip in at least one change you might plausibly forget, like a stray edit in a second file.
2. Create a file notes.md and write one line predicting what you changed, from memory.
3. Ask Claude: 'Summarize what I've changed, and flag anything that looks unintended.' Paste its summary into notes.md under your prediction, then add a sentence on whether it caught the stray change.
4. Have Claude commit notes.md on a new branch — tell it 'commit on a branch called read-repo and push it.'
5. Create a PR and submit it.
