What Is Claude Code? The AI-Powered Developer

Claude Code is not a chatbot. It is an agentic coding assistant that reads your files, runs commands, and edits code directly inside your real project — the gap between describing and doing, closed.

Installing Claude Code

One installer, one login, and you're running. Install with a one-line native installer (no Node.js required), log in with your Claude subscription or an API key, and start your first session — every step with the exact commands and what to expect.

Writing Your First Web Page with Claude Code

Create a project folder, ask Claude to build an HTML/CSS/JS page, iterate on the design, and open it in your browser — your first complete build cycle from prompt to live preview.

Understanding Context — How Claude Sees Your Project

Claude does not have eyes on your codebase by default — it reads what you give it or what it fetches via tools. Understanding context limits, CLAUDE.md, and session management makes you dramatically more effective.

Commands, Shortcuts, and Slash Commands

The complete reference for Claude Code slash commands, keyboard shortcuts, CLI flags, and configuration — from /help to --dangerously-skip-permissions, covering every control you need for efficient daily use.

Choosing Your Model in Claude Code

Anthropic ships new models every few weeks. If your workflow is built on version numbers, it breaks every few weeks. Build it on aliases and tiers instead — type the role you want, let Claude Code resolve the build, and pick your rung by the job in front of you.

Debugging with Claude Code

Paste the error, give Claude context, watch it diagnose and fix — then learn how to read tool outputs, when to reframe stuck loops, and how to add regression tests so the bug never returns.

Your First Full Project — Build a Portfolio Page

From blank folder to deployed app — plan with CLAUDE.md, build iteratively, connect a live weather API, prove loading and failure states, and ship. This is the complete beginner-to-working-software workflow.

Extending Claude Code: Your First MCP Server and Subagent

Claude Code ships with a fixed set of built-in tools — but you can extend it. Add a public MCP server in one command to give it new capabilities, then create a subagent to delegate focused work in an isolated context. This is the hands-on bridge from user to power user.
