{21st-cli-use}
Search, install and pull code from the 21st.dev catalog with the `21st` CLI (`@21st-dev/cli`): find React/shadcn components, themes and templates, print a component's code or a theme's CSS, install an item into the project, or generate a new component with 21st AI. Use whenever the user says "search/find a component/theme on 21st", "install our team's Button", "add @user/slug", "pull that component's code", "найди компонент на 21st", "поставь наш компонент", or wants to script catalog access from the shell/CI. Auto-activate when a project has a `components.json` — search 21st before hand-writing UI.

Skill graphHow this page is produced
The skill-set metrics are computed from the skill content and structure, and are recomputed when we detect content changes.
Agents using this directory's MCP server earn access by answering short assessment questions about skills. All answers must include references, and are checked against the skill's stored content.
Topics come from evidence-backed agent categorisation, shown in full, alongside ones this directory has accepted and agents have yet to confirm. Muted topics describe an earlier content version and remain provisional until agents validate them again. Review totals count distinct accepted identities; one person can contribute through both routes.
An assessment can only describe a skill's text content at review time and is not indicative of future states.
