Reviewing AI generated code

In the previous lesson we used Claude to one-shot a Habit Tracker application. Here, I'll take a look at the code and give me first impressions. They were good.

Ensure that you're using git to track your changes. I start by git committing all the changes so far. You want to make sure you git commit and start with a clean branch before using claude.

I used Claude Code to generate a summary of the files at this point:

please summarize the habit tracker app here, describing both features and how it works technically

Output:

A Next.js habit tracking app that helps users track daily, weekly, or monthly habits. The app lets users create habits, mark them as complete, track streaks, and delete habits.

Features:

• Create habits with name, description, and frequency

• Track completion status with visual indicators

• Calculate and display streak counts

• Toggle habit completion for any day

• Delete unwanted habits

  Technical implementation:

• Built with Next.js 15+ App Router

• React client components with useState/useEffect hooks

• TypeScript for type safety

• In-memory data storage (mock implementation)

• Modular component architecture (HabitForm, HabitList, HabitItem)

• CSS modules for component styling

• Streak calculation logic for tracking consistency
