Overview
This lecture introduces Claude Code, an AI-driven coding platform designed for technical and non-technical users, explaining its unique features, installation steps, and efficient workflows for building and managing software projects.
What is Claude Code?
- Claude Code is an AI coding assistant by Anthropic for building, debugging, and planning software using natural language commands.
- Unlike traditional coding tools, Claude Code enables parallel task execution through sub-agents, improving efficiency.
- It is accessible to both technical and non-technical users, aiming to democratize software development.
- Claude Code supports a million-token context window, allowing for larger projects and richer conversations.
Key Features and Advantages
- Sub-agents: Specialized AI agents handle different tasks in parallel.
- Planning Mode: Uses powerful models like Opus for step-by-step planning and project breakdowns.
- Slash Commands: Quick commands such as /clear, /compact, /init, and /res streamline session management.
- Integration: Works within various environments (terminal, Cursor, VS Code, Warp) for flexible usage.
- MCP Servers: Add plugins to enable browser control, web scraping, and advanced automations.
Getting Started & Installation
- Install Node.js from nodejs.org for compatibility with Mac, Windows, and Linux.
- Download Claude Code, preferably via official links.
- Use terminals like Warp for an easier, AI-assisted command line experience.
- Set up Claude Code in coding editors or platforms like Cursor or VS Code.
- Initial setup requires signing in with an Anthropic account (higher plans allow more usage).
Workflow & Best Practices
- Start simple: Use natural language prompts to build apps, websites, or automation.
- Use At (@) symbol to target specific files as projects grow to avoid confusion and keep context focused.
- Screenshot or paste images directly to Claude Code for visual feedback and design improvements.
- Generate and maintain project documents (Markdown files) for persistent memory, summaries, or design principles.
- Build modularly: Focus sessions on specific domains (design, backend, database) to reduce confusion.
Advanced Tools & Customization
- Add and manage MCP servers (e.g., Playwright for browser automation, Exa for web search).
- Spin up agents for role-based tasks such as project management or UI design.
- Create custom slash commands to optimize workflows, output styles, and security reviews.
- Use project-specific and global settings (settings.json and settings.local.json) for tailored configurations.
Key Terms & Definitions
- Claude Code — AI-powered coding assistant by Anthropic that automates software development tasks.
- Context Window — The amount of data (tokens) the AI can consider in a session.
- Sub-agent — An AI entity specializing in a particular function within a project.
- MCP (Model Context Protocol) — Framework for securely connecting Claude Code to external services and APIs.
- Slash Commands — Quick text commands (e.g., /clear, /init) to control Claude Code sessions.
- Markdown (.md) File — Text file for project documentation and persistent memory in Claude Code.
Action Items / Next Steps
- Install Node.js and Claude Code; set up your preferred terminal/editor.
