What you'll build

Step-by-step guide to using Claude Code CLI. Build a working share feature in 90 minutes while learning how to code with AI assistance directly in your terminal.

1. Set Up Claude Code

Install Claude Code CLI, authenticate with Anthropic, and configure your IDE terminal.

2. Initialize Your Project

Use /init to generate CLAUDE.md memory file and teach Claude about NextSound.

3. Plan with Plan Mode

Use Shift+Tab to create a three-stage implementation plan for the share feature.

4. Build Stage by Stage

Implement share button, clipboard functionality, and toast notification incrementally.

5. Monitor Costs & Optimize

Use /cost to track usage and /model to choose the right AI model for your budget.

Your portfolio builds as you work.

Every project documents itself as you go. Finish the work, and your proof is ready to share.

FAQs

Everything you need to know

Claude Code is a command-line interface (CLI) tool that brings Claude AI directly into your terminal. Unlike browser-based Claude, Claude Code has access to your entire codebase, can edit files directly, run terminal commands, and understand project context immediately. This makes it ideal for real development work where you need AI to read, write, and modify code in place.

Claude Code uses pay-as-you-go API billing through your Anthropic account. You need to add a minimum of $5 USD credit to get started. This 90-minute project typically costs $2-5 USD depending on which model you choose. You can monitor costs anytime with the /cost command and set spending limits in your Anthropic Console to prevent unexpected charges.

No prior coding experience is required. This tutorial is designed specifically for complete beginners. Claude Code explains what it is doing as it works, answers questions in real-time, and handles implementation details automatically. You will learn by doing - building a working share feature while Claude guides you through each step.

Plan mode is activated by pressing Shift+Tab before typing your prompt. It tells Claude to create a detailed implementation plan without making any code changes. Plan mode is perfect for complex features because it lets you review the approach, make adjustments, and confirm you agree with the strategy before any code is written. Use it whenever you want to think before you build.

This project includes multiple support options. Each section has validation checkpoints to confirm you're on track, plus detailed troubleshooting guides for common issues. Join the NextWork Discord community for peer support and mentorship. You can also use Claude Code itself to debug problems - just describe what's wrong and it will suggest fixes.

One Project. Real Skills.

90 minutes from now, you'll have completed Build a New App Feature With Claude Code. No prior experience needed. Just step-by-step guidance and a real project for your portfolio.
