Anthropic's Claude Code CLI is a command-line tool that brings AI assistance directly to your terminal. Unlike web interfaces, it works where you are already developing.
What is Claude Code CLI?
It is an AI agent that runs in your terminal with full access to your file system, git, and development tools. It can read, write, and modify files, execute commands, and manage complete projects.
Claude Code CLI understands your project context: directory structure, tech stack, dependencies, and git history.
Getting started
It installs with a simple npm command: npm install -g @anthropic-ai/claude-code. Once installed, run claude in your project directory and start interacting.
Main features
File editing: ask Claude to modify functions, add code, or refactor complete files. It understands project conventions.
Terminal commands: Claude can execute commands, read their output, and act accordingly. For example, run tests and fix found errors.
Git integration: it can create commits, branches, and PRs. It understands diff and can write descriptive commit messages.
Project search: quickly find function definitions, references, and patterns across the entire codebase.
Use cases
Debugging: Describe a bug and Claude investigates the code, identifies the cause, and proposes a solution.
Refactoring: Ask for architectural changes and Claude implements them across all necessary files.
Code review: Claude can review PRs, identify issues, and suggest improvements.
Best practices
Be specific in instructions. Use references to concrete files. Always review changes before accepting. Use claude in version-controlled projects to be able to revert changes if needed.
