Claude Code is Anthropic’s AI-powered coding agent that lives directly in your terminal. Unlike chatbot-style assistants that require copy-pasting code back and forth, Claude Code reads your actual codebase, edits real files, runs shell commands, and executes tests — all autonomously from within your development environment.
The article explains what Claude Code is and how it differs from other AI coding tools, then walks through installation options (native binary, Homebrew, and deprecated npm), authentication, and first-project setup. It outlines Claude Code’s architecture (a CLI engine coordinating file system access, shell commands, and the Anthropic API), describes what you can use it for—code generation, debugging, documentation, test writing, refactoring, dependency upgrades, and CI/CD/DevOps tasks—and covers advanced capabilities like multi-agent parallel work via Git worktrees. It also provides a command reference (CLI flags, in-session slash commands, automation/print mode), discusses project memory via CLAUDE.md, shows how MCP servers extend Claude Code to external systems, and ends with safety best practices and final guidance on starting simple.
