UX-OS / Design systems

Design systems

Tokens, components, naming, governance and documentation.

Claude reaches for whatever value looks right. These hold it to the tokens and components you already chose.

What's missing: Mine enforce a system you already have. Nothing of mine builds one.

The @designer-skills commands below need this once.

/plugin marketplace add Owl-Listener/designer-skills

design-systems

Skill pack by MC Dean

Tokens, component specs, naming, theming, icons, motion systems, governance, pattern libraries and accessibility audits.

/plugin install design-systems@designer-skills

MCP server by Bill Bulman and Claude

Checks UI code against a design system's tokens and components.

Testing: Ships with its own test suite.

Clone the repo and add it as an MCP server. The README has the steps.

Loads on its own

Agent by Bill Bulman and Claude

Drives live page violations to zero without changing how a page looks unless a person approves it.

Runs only on Workshopr, so there is nothing to install.

Run by name

The states are from my setup on 9 November 2026. Yours start from whatever you install.
