What is Claude Code?

Claude Code is Anthropic's official CLI for Claude — an agentic coding tool that lives in your terminal. It reads your codebase, runs commands, edits files, manages git, and can spawn specialist sub-agents to handle parallel workstreams. It's designed for software engineers who want AI that actually understands their project context.
