Claude Code is Anthropic's command-line tool that brings Claude directly into your terminal. It can read, edit, and create files, run commands, search codebases, and handle complex multi-file coding tasks autonomously.

How does Claude Code compare to Cursor?

Claude Code works in the terminal (CLI-first) while Cursor is an IDE. Claude Code excels at large refactors, multi-file changes, and automation via scripts. Cursor is better for interactive, visual coding. Many developers use both.

Claude Code requires an Anthropic API key and charges based on token usage. It uses Claude Sonnet by default but can switch to Opus for complex tasks. Typical costs range from $5-50/day for active development depending on usage.

How do I install Claude Code?

Install via npm: `npm install -g @anthropic-ai/claude-code`. Then run `claude` in any directory to start. You'll need an Anthropic API key set as ANTHROPIC_API_KEY environment variable. Works on macOS, Linux, and Windows (WSL).

What can Claude Code do automatically?

Claude Code can autonomously: refactor entire codebases, implement features across multiple files, write and run tests, fix bugs by reading error logs, set up project configurations, and execute shell commands. It asks permission before destructive operations.

Can Claude Code work with any programming language?

Yes, Claude Code is language-agnostic. It excels at Python, JavaScript/TypeScript, Go, Rust, and most popular languages. It understands project structures, package managers, and build tools for each ecosystem.

How do I control Claude Code's costs?

Use `--model haiku` for simple tasks (10x cheaper). Set spending limits in your Anthropic dashboard. Use `.claudeignore` to exclude large files from context. Review the token usage shown after each response to understand costs.
