Unit 4 Git playground — Lesson 4

A tiny command-line notes tool, used as the practice repo for Unit 4, Lesson 4 (reviewing code). This repo has a branch called review-me with a small change on it — and a bug planted in that change on purpose. Your job is to have Claude review it and see whether it catches the bug.

The app

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

Layout: notes.js is the entry point, lib/store.js loads, saves, and searches notes, lib/config.js holds settings, and tests/ holds the test suite (npm test).

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 folder.

Lesson 4 task — review a pull request

Goal: open the review-me pull request, have Claude review it, and judge whether it caught the planted bug.

1. Check the branch is there. Run git branch -a — you should see review-me. It came with your copy.
2. Open the PR. Ask Claude: "Open a pull request for the review-me branch."
3. Have Claude review it. Ask: "Review this PR — look for bugs, edge cases, and anything risky."
4. Judge the review. One bug was planted on purpose. Did Claude catch it? Note what it flagged and whether it found the real problem.
5. Comment. Add a one-line comment on the PR saying whether Claude caught the bug.
6. Submit the pull request link.
