My Experience
I use Claude CLI as my rapid consultation tool in my three-tool AI development workflow. While Cline handles complex planning and Cursor manages active development, Claude CLI is perfect for quick questions and exploring different approaches.
My AI Development Toolkit
- Cursor - Primary IDE for hands-on coding and real-time assistance
- Cline - Specialized for complex planning and architectural decisions
- Claude CLI - Quick consultations and rapid prototyping
Where Claude CLI Excels
