Use this skill when working on an Expo or React Native app that uses, adds, debugs, or migrates to Convex. It covers `npx convex dev`, `EXPO_PUBLIC_CONVEX_URL` and EAS envs, `ConvexReactClient` and provider wiring in `expo-router` or `App.tsx`, generated `api` imports, schema and index design, queries, mutations, actions, auth (Clerk, Convex Auth, JWT or OIDC), file uploads from Expo URIs, pagination, migrations, and common `useQuery` or `_generated` failures. Do not use it for generic Expo UI or navigation work, or for non-Expo Convex frontends unless the task is specifically about adapting them to this mobile stack.
Create logo components with multiple variants (icon, wordmark, logo) and light/dark modes. Use when the user provides logo SVG files and wants to create a variant-based logo component following the Clerk pattern in the Elements project.
Production-ready starter project for React + Cloudflare Workers + Hono with core services (D1, KV, R2, Workers AI) and optional advanced features (Clerk Auth, AI Chat, Queues, Vectorize).

Use when: starting new full-stack project, creating Cloudflare app, scaffolding web app, AI-powered application, chat interface, RAG application, need complete starter, avoid setup time, production-ready template, full-stack boilerplate, React Cloudflare starter. Prevents: service configuration errors, binding setup mistakes, frontend-backend connection issues, CORS errors, auth integration problems, AI SDK setup confusion, missing planning docs, incomplete project structure, hours of initial setup. Keywords: cloudflare scaffold, full-stack starter, react cloudflare, hono template, production boilerplate, AI SDK integration, workers AI, complete starter project, D1 KV R2 setup, web app template, chat application scaffold, RAG starter, planning docs included, session handoff, tailwind v4 shadcn, typescript starter, vite cloudflare plugin, all services configured
Create new UI elements for tryelements.dev registry. Use when: (1) Adding new UI components (buttons, inputs, cards), (2) Building integration components (Clerk, Stripe, Uploadthing), (3) Creating theme-related elements, (4) Any shadcn-style registry component. IMPORTANT: For logo components with variants (icon/wordmark/logo + dark/light), use the logo-with-variants skill instead. This skill includes scaffolding, registry schema, and component patterns. ALWAYS use Context7 MCP to fetch latest dependency docs before implementing.
Patterns for reliable external service integration: env validation, health checks, error handling, observability. Invoke when integrating Stripe, Clerk, Sendgrid, or any external API.
Self-contained SaaS pipeline — invoke directly, do not decompose. Generates a Vibes app, adds auth + billing, and deploys live. Uses Agent Teams to parallelize for maximum speed.
Self-contained app generator — invoke this skill directly, do not decompose into sub-steps. Generates React web apps with Fireproof database. Use when creating new web applications, adding components, or working with local-first databases. Ideal for quick prototypes and single-page apps that need real-time data sync.
This skill should be used when the user asks to "deploy to castari", "deploy my agent", "deploy agent to production", "castari deploy", "push agent to castari", "ship my agent", "set up castari", or needs help with Castari CLI installation, authentication, agent scaffolding, or deployment to cloud sandboxes.
Self-contained deploy automation — invoke directly, do not decompose. Deploys a Vibes app to Cloudflare Workers with subdomain registry. Uses KV for storage and native Web Crypto for JWT verification.
