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`.
MUST activate to localize / internationalize a uiBundles/*/src/ React project: extract hardcoded user-facing strings into Custom Labels, wire i18next over the Platform SDK GraphQL backend, add a language to a localized bundle, or troubleshoot label rendering across locales. Triggers: user-facing string literals in .tsx/.jsx, a CustomLabels.labels-meta.xml, a src/i18n/ directory or label-manifest.ts, t(…) calls, or requests to 'translate / localize / internationalize / support another language.' Scope: authenticated UI Bundles only (B2E CustomApplication-bound, or in-core accessCheck-bound apps). DO NOT TRIGGER when: the bundle is a site (B2C/B2B) app bound to a DigitalExperienceConfig (site localization not yet supported), building app shell/UI or styling, reading/writing/refreshing records (use experience-ui-bundle-salesforce-data-access), generating a new bundle (use experience-ui-bundle-frontend-generate), deploying (use experience-ui-bundle-deploy), or authoring translations in Translation Workbench.

Build native-feeling, benchmark-quality mobile app screens (Expo / React Native). Use when designing or implementing any mobile UI — screens, flows, onboarding, paywalls, tab bars, settings, empty states — or when polishing motion, typography, dark mode, or perceived performance. Enforces Apple HIG fidelity, semantic colors, native controls, purposeful Reanimated motion, a simulator-verified iteration loop, and a study-real-apps-first workflow (pairs with the Appllama MCP). Trigger on "build a screen", "make this screen better", "design the onboarding", "polish the UI", "make it feel native", or any mobile design/implementation task.

Covers setup, data binding, accessibility, keyboard navigation, common methods and properties, and integration patterns.

Implement customer email in a Customware-generated React Router and Hono app, including durable Postmark inbound receipt and direct Postmark outbound sending. Use when a Builder task names the customware-email skill, provides a Postmark virtual inbound address, or asks to add customer-facing email to an existing Customware app.
