Add frontend-design skill to the Cowork plugin marketplace

[zukethenuke]

Description

The frontend-design plugin currently only exists in the anthropics/claude-code repo and is only installable via the Claude Code CLI. It is not available in Cowork sessions.

Given that Cowork is a primary way users interact with Claude for building things — including frontend interfaces — the frontend-design skill should be available in the Cowork plugin marketplace alongside the existing 11 knowledge-work plugins.

Why This Matters

Cowork users who build frontend applications (React, React Native, Vue, etc.) currently get no design-quality guidance from Claude in Cowork sessions, even though the same guidance is available in Claude Code via the frontend-design plugin. This creates an inconsistent experience across Anthropic products.

The skill itself is a single SKILL.md file, so adding it to this marketplace would be straightforward.

Proposed Solution

Add a frontend-design plugin to this repo, either:

1. Copy the skill from anthropics/claude-code/plugins/frontend-design into this marketplace, or
2. Unify the plugin systems so Claude Code plugins are automatically available in Cowork
