Claude Code is no longer only a terminal experience.

The terminal CLI is still the best surface for this course because it exposes the local repository, shell tools, permissions, and automation clearly. But Claude Code also appears in IDEs, the desktop app, the web environment at claude.ai/code, GitHub and GitLab workflows, Slack, and MCP-connected systems.

The same project instructions and habits matter across these surfaces. What changes is the execution environment: local terminal, IDE, managed cloud session, or workflow integration.
