Claude Code
Claude Code is an agentic coding tool from Anthropic that runs in the terminal and integrates with your integrated development environment (IDE) to turn natural language instructions into repository-aware edits, test runs, and pull requests.
It’s designed for deep, multi-file changes across large codebases, executing commands in your environment and surfacing diffs for review to support debugging and everyday development. It can also run unattended: an @Claude mention in Slack starts a task, GitHub Actions and GitLab CI/CD wire it into a CI pipeline for automated pull request reviews and issue triage, and scheduled routines run recurring work on Anthropic-managed infrastructure. Beyond the terminal, Claude Code is also available as a desktop app for macOS, Linux, and Windows, a web app at claude.ai/code, on mobile through the Claude app for iOS and Android, and as extensions for VS Code (including forks like Cursor) and JetBrains IDEs. All surfaces share the same underlying engine, so your CLAUDE.md files, settings, and MCP servers work everywhere. Further extension points include skills that package repeatable workflows, hooks that run shell commands before or after Claude Code actions, and subagents that work on separate parts of a task, each in its own context window.
