SuperDesign helps you (1) find design inspirations/styles and (2) generate/iterate design drafts on an infinite canvas.

Core scenarios (what this skill handles)

1. superdesign init — Analyze the repo and build UI context to .superdesign/init/
2. Help me design X (feature/page/flow)
3. Set design system
4. Help me improve design of X

Init: Repo Analysis

When .superdesign/init/ directory doesn't exist or is empty, you MUST automatically:

1. Create the .superdesign/init/ directory
2. Fetch the init prompt from the URL below
3. Follow the prompt instructions to analyze the repo and write context files

Do NOT ask the user to do this manually — just do it.

Mandatory Init Files

If .superdesign/init/ exists, you MUST read ALL files in this directory FIRST before any design task:

• components.md — shared UI primitives with full source code
• layouts.md — shared layout components (nav, sidebar, header, footer)
• routes.md — page/route mapping
• theme.md — design tokens, CSS variables, Tailwind config
• pages.md — page component dependency trees (which files each page needs)

When designing for an existing page: First check pages.md for the page's complete dependency tree. Every file in that tree MUST be passed as --context-file. Then also add globals.css, tailwind.config, and design-system.md.

Superdesign CLI (MUST run before any command)

IMPORTANT: Before running ANY superdesign command, you MUST ensure the CLI is installed and logged in.

Follow these steps in order — do NOT skip any step:

1. Check if CLI is already installed:

   superdesign --version

   • If the command succeeds (prints a version), skip installation and go to step 2.
   • If the command fails (not found), install the CLI:

     npm install -g @superdesign/cli@latest

2. Check login status by running any command (e.g. superdesign --help). If you see an auth/login error, run:

   superdesign login

   Wait for login to complete successfully before proceeding.

3. Only after login succeeds, run your intended superdesign commands.

Never assume the user is already logged in. Always verify login first.
