What is Claude Code?
Claude Code is an agentic coding tool that works in your terminal, IDE, desktop app or browser. You describe what you want; it explores the codebase, plans, edits files, runs commands and tests, and commits — asking for permission as configured.
It can be extended with MCP servers, skills and hooks, and run in CI to handle issues and reviews.
