Claude Code

Anthropic's agentic coding CLI; the one you're reading this in.

Claude Code is Anthropic's official command-line coding agent that runs in the terminal and works directly against a developer's codebase. It can read and edit files, run shell commands, execute git operations, and complete multi-step engineering tasks while using tools and MCP servers. It is also embeddable in CI and scriptable workflows via its SDK and headless modes.
