Does it only look at package.json?

No, it uses a multi-signal approach including components.json styles, source code import patterns, and HTML data attributes for maximum accuracy.

Why is detection necessary before adding components?

Shadcn/ui can use different primitives like Radix or Base UI; detection ensures new components use the correct patterns, styles, and attributes for your specific setup.

How does it handle projects with both Radix and Base UI?

It identifies a 'Mixed' state and flags it as a migration case, allowing you to choose the target primitive rather than guessing.

Can it identify my package manager?

Yes, it analyzes lockfiles (bun, pnpm, yarn, npm) to ensure commands like 'npx' or 'pnpm dlx' are used correctly according to your environment.

デザインツール

Identifies the underlying primitive library (Radix UI or Base UI) within shadcn/ui projects to ensure framework-specific compatibility.

This skill automates the discovery phase of frontend development by analyzing a codebase to determine if it utilizes Radix UI or Base UI as its shadcn/ui foundation. By scanning package dependencies, configuration files, import patterns, and HTML data attributes, it provides a weighted accuracy score to identify the current stack, detect mixed migration states, and identify the project's package manager. This ensures that subsequent component generations or modifications align perfectly with the existing architecture, preventing style conflicts and breaking changes.
