Claude CLI

Anthropic's agentic AI coding assistant: build, debug, and automate code tasks directly from your terminal.

The Claude Code CLI is Anthropic's powerful AI pair programmer, delivering autonomous coding capabilities via your command line. Developers run the `claude` command to initiate an interactive REPL, then leverage Claude's agentic abilities to fix bugs, generate features from plain English descriptions, and navigate complex codebases. The tool reads your project files, executes commands like `git` and `npm`, and proposes code changes, always requesting permission before file modification. Installation is straightforward via npm (`npm install -g @anthropic-ai/claude-code`), requiring an active Claude Pro or Max subscription for access.
