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.
Look at the current project's design (its shadcn / Tailwind CSS variables and color tokens) and publish it to the 21st.dev community as a shareable theme, using `21st publish-theme`. Use when the user says "publish my theme", "share our design as a 21st theme", "sync my design to 21st", "turn my globals.css into a theme", "залей наш дизайн темой", "опубликуй тему". This is the 21st equivalent of design-sync: it reads the project's design tokens and syncs them into the public theme library.
Publish your own work to 21st.dev and manage it from the terminal with the `21st` CLI (`@21st-dev/cli`): publish a React component to a team library, publish a CSS theme or a template listing, edit / unpublish / delete your published items, and read/replace your public profile page (bento board). Triggers when the user says "publish/share/upload this to 21st", "залей в наш регистр", "опубликуй компонент/тему/темплейт", "share with team", "make this reusable", "unpublish/edit/delete my component", "change its visibility", "add this to my 21st profile/bento", "update my profile page", "обнови мой профиль на 21st", "добавь блок в бенто". For finding and installing existing items use `21st-cli-use`; for turning a project's design tokens into a theme use `21st-design-sync`.
Generate and iterate on UI with 21st AI from the terminal via the `21st` CLI (`@21st-dev/cli`): sketch a UI from a prompt, preview the variants in the browser, edit any variant in place with a natural-language change, and pull the final code into the project. Use whenever the user wants to BUILD / SKETCH new UI ("sketch a pricing page", "generate a hero with 21st", "make me a <X> section"), ITERATE on a generated draft ("edit the third variant", "add a toggle to that take"), or GRAB the code of a draft ("pull that variant's code", "сгенери UI на 21st", "поправь третий вариант", "забери код того наброска"). For finding/installing existing components use the `21st-cli-use` skill; to publish your own, `21st-registry`.
