21st-dev-components

92 / 100 · Low risk

Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

By J-StaR-Films-Studios/VibeCode-Protocol-Suite (GitHub) · coding · 26 stars · scanned at commit bb9e238

Use when the user wants to build a React site or app section from 21st.dev components, clone the structure of a reference site with 21st.dev building blocks, browse 21st.dev manually and return copied prompts/code, or says things like "build me a site like this", "use 21st.dev", "copy prompt", "component URL", "hero from 21st", or "match this landing page with ready-made components".

Works with any agent that supports SKILL.md skills.

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'21st-dev-components' ] || [ -L ~/.agents/skills/'21st-dev-components' ]; then echo 'A skill folder named 21st-dev-components already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/J-StaR-Films-Studios/VibeCode-Protocol-Suite' "$d" && git -C "$d" checkout --quiet 'bb9e2387e4c7cb850ab9795fd8630486991c0337' -- 'assets/.agent/skills/frontend-ui/21st-dev-components' && mkdir -p ~/.agents/skills && cp -R "$d"/'assets/.agent/skills/frontend-ui/21st-dev-components' ~/.agents/skills/'21st-dev-components' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'21st-dev-components' ~/.claude/skills/'21st-dev-components' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
