/design login # Authenticate with claude.ai for Design access
/design consent # Grant Claude agent access to your Design projects
/design <prompt> # Route to Design operations (import, export, status, etc.)Details

list_projects,read_file,write_files,delete_files,finalize_plan,get_claude_design_prompt,render_preview, and more - Write operations (
