quickstart

Set up recurring scheduled jobs (crons) on Convex — digests, cleanups, polling, retries. TRIGGER when the user wants a recurring/scheduled task ('every day/hour', cron, periodic cleanup). Targets internal functions, idempotent handlers.

Design and build reactive, type-safe, production-grade backends on Convex. Covers schema, queries/mutations/actions, indexes, auth, file storage, scheduling, real-time multiplayer, mobile backends, and LLM/agent workflows on Convex's one-platform stack.

Wire a domain the user ALREADY OWNS (GoDaddy/Namecheap/Cloudflare/…) to their Convex app: exact DNS records, custom-domain attachment, auth-origin rebind. TRIGGER when the user owns a domain and wants it pointing at their app ('point my domain at this', 'use my own domain', 'set up example.com'). Never asks for registrar credentials.

Set + wire deployment env vars / secrets (API keys) for a Convex app — stored in Convex env, read in actions, never hardcoded. TRIGGER when the user needs an API key/secret/env var ('add my OpenAI key', 'set an env var').

LABS — scaffold a running Next.js + shadcn Convex app with passkey sign-in and a live Chef feedback panel, then build and verify it locally. TRIGGER for the full/labs quickstart, passkeys, or the feedback panel in a new app. For a plain scaffold use quickstart. Legacy convex.app publishing is retired; use a separate hosting workflow if requested. SKIP when a Convex project already exists in the cwd.

Safely migrate the schema + backfill data on a deployed Convex app with @convex-dev/migrations. TRIGGER when changing the schema on a live app, backfilling data, or after a schema-validation error from a change. SKIP a fresh local app.

Seed the Convex database with starter/fixture data or import an existing dataset (CSV/JSON). TRIGGER when the user wants sample/seed data or to import a dataset into Convex. Idempotent, schema-matching.

Proactively suggest the right Convex component when the user hand-rolls what already exists: setInterval polling → crons, counter increments → sharded-counter, .collect() counts → aggregate, email → resend, DB-counter rate limiting → rate-limiter, uploads → storage, search, presence, multi-step actions → workflow, vector DB → rag, collaborative editing → prosemirror-sync. TRIGGER on noticing the pattern in a Convex app, AFTER completing the user's request. NEVER for non-Convex code.

Guidance for distinctive, intentional visual design when building new UI or reshaping an existing one. Helps with aesthetic direction, typography, and making choices that don't read as templated defaults.

Build a throwaway prototype to answer a design question. Use when the user wants to sanity-check whether a state model or logic feels right, or explore what a UI should look like.

React and Next.js performance optimization guidelines from Vercel Engineering. This skill should be used when writing, reviewing, or refactoring React/Next.js code to ensure optimal performance patterns. Triggers on tasks involving React components, Next.js pages, data fetching, bundle optimization, or performance improvements.

Review UI code for Web Interface Guidelines compliance. Use when asked to "review my UI", "check accessibility", "audit design", "review UX", or "check my site against best practices".

React composition patterns that scale. Use when refactoring components with boolean prop proliferation, building flexible component libraries, or designing reusable APIs. Triggers on tasks involving compound components, render props, context providers, or component architecture. Includes React 19 API changes.

React Native and Expo best practices for building performant mobile apps. Use when building React Native components, optimizing list performance, implementing animations, or working with native modules. Triggers on tasks involving React Native, Expo, mobile performance, or native platform APIs.

Guide for implementing smooth, native-feeling animations using React's View Transition API (`<ViewTransition>` component, `addTransitionType`, and CSS view transition pseudo-elements). Use this skill whenever the user wants to add page transitions, animate route changes, create shared element animations, animate enter/exit of components, animate list reorder, implement directional (forward/back) navigation animations, or integrate view transitions in Next.js. Also use when the user mentions view transitions, `startViewTransition`, `ViewTransition`, transition types, or asks about animating between UI states in React without third-party animation libraries.

Suite of tools for creating elaborate, multi-component claude.ai HTML artifacts using modern frontend web technologies (React, Tailwind CSS, shadcn/ui). Use for complex artifacts requiring state management, routing, or shadcn/ui components - not for simple single-file HTML/JSX artifacts.
