Claude Code — an agentic tool for developers

Claude Code is an agentic coding tool that works where you work: in the terminal, integrated development environment, browser, or even Slack. It understands your codebase, executes commands, and manages entire development workflows through natural language. When to use Claude Code. When you want to build features by describing what you need in plain language, and have Claude write the code, run tests, and create commits. When you need to debug issues: paste in error messages, and Claude will analyze your codebase to find and fix problems. When you're working with an unfamiliar codebase and want to ask how different parts work together. When you need to automate routine tasks: fixing linter errors, resolving merge conflicts, writing release notes. When you prefer to work in the terminal alongside your familiar development environment, rather than switching to a separate interface. Claude Code is fundamentally different from Chat mode in that it has direct access to files, can execute commands, and saves changes to real files.
