What is Claude Code?
Claude Code is an AI coding agent developed by Anthropic. It runs in the terminal and automatically generates, edits, debugs, and deploys code based on natural language instructions.
Unlike traditional code completion tools (GitHub Copilot, Cursor), Claude Code takes an agent-based approach. It doesn’t just suggest code — it autonomously reads and writes files, executes commands, and fixes errors.
What Can Claude Code Do?
- Automatic code generation — Generate multi-file code from instructions like “Build a React dashboard”
- Bug fixing — Paste an error log and Claude identifies the cause and applies a fix
- Refactoring — Suggests and executes improvements to existing code
- Test creation — Automatically generates tests for existing code
- Git operations — Automates commits, branch creation, and PR creation
