Xantham has a deep frontend skill stack. 21st.dev fills one specific slot: getting a battle-tested React component fast without hand-coding the structure.
Xantham 21st Bridge is a community-contributed Claude Code skill in the ux-research sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/xantham-21st-bridge/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when generating a React UI component (pricing table, form, modal, dashboard tile, navbar, hero, AI-chat surface) and the goal is "novel functional component with sensible defaults". Routes to 21st.
The Xantham 21st Bridge Claude Code skill is built for product managers, product designers, and cross-functional teams planning, shipping, and measuring product features. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 69,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
