Claude Code is an agentic coding tool from Anthropic that runs in the terminal, VS Code, JetBrains IDEs, a desktop app, and on the web. Unlike browser-based chat interfaces, it reads your entire codebase, edits files, runs shell commands, and manages Git autonomously through a plan-execute-verify loop. Advanced features include MCP for connecting to external tools, subagents for delegating focused tasks, experimental agent teams for parallel multi-session coordination, custom skills and slash commands, hooks for automation, and GitHub integration. Pricing ranges from $20/month (Pro) to $200/month (Max 20x) or API pay-per-use. Installation is via a native installer that replaced the older npm method. Compared to Cursor, Claude Code emphasizes autonomous agentic execution over step-by-step diff review.
