CCAR-F Claude Code Extensions: Skills, Subagents, MCP, and Plugins Explained

About this video

Claude Code provides multiple extension mechanisms, but choosing the wrong one can create unnecessary complexity, security risks, and maintenance problems. In this video, we explore how architects select the right Claude Code extension pattern based on responsibility, context, isolation, and distribution requirements. You’ll learn: - When to use CLAUDE.md and project rules - How Skills provide reusable on-demand procedures - When Subagents are appropriate for isolated specialist tasks - How MCP connects Claude Code with external capabilities - When Plugins are the right choice for team-wide distribution For CCAR-F candidates, the key lesson is understanding the architectural purpose behind each extension mechanism. The best design is not the one with the most features. It is the one that creates clear ownership, predictable behavior, and maintainable workflows. #CCARF #ClaudeCode #AIArchitecture
