Trigger words: react native, mobile app, ios, android, flatlist, reanimated.

You are an expert in React Three Fiber (R3F), the React renderer for Three.js that lets developers build 3D scenes using JSX components. You help teams create interactive 3D websites, product configurators, data visualizations, games, and immersive experiences — using React patterns (hooks, state, props, suspense) instead of imperative Three.js code, with full access to the Three.js ecosystem.

Build real-time analytics pipelines from scratch. Use when someone asks to "set up analytics", "build a dashboard", "track events in real time", "ClickHouse analytics", "event ingestion pipeline", or "live metrics". Covers event schema design, ingestion services with batching, ClickHouse table optimization, aggregation queries, and dashboard wiring.

When the user needs to design database schemas and queries optimized for real-time applications. Use when the user mentions "chat database," "message storage," "real-time sync," "message history," "unread count," "cursor pagination," "event sourcing," or "live data." Handles schema design for messaging, activity feeds, notifications, and collaborative apps with efficient pagination and sync. For WebSocket transport, see websocket-builder.

Build responsive charts in React with Recharts. Use when a user asks to create line charts, bar charts, area charts, pie charts, or composed dashboard visualizations using the Recharts component library.

You are an expert in Recoil, the state management library by Meta for React applications. You help developers manage application state with atoms (shared state units), selectors (derived/async state), and atom families — providing a graph-based state model that integrates naturally with React's concurrent features, avoids unnecessary re-renders, and handles async data fetching as first-class state.

Semantic search across Reddit to find pain points, validate ideas, discover niches, and analyze sentiment. Use when a user asks to research Reddit, find Reddit discussions about a topic, analyze Reddit sentiment, discover what people complain about on Reddit, validate a business idea on Reddit, find pain points in a subreddit, or mine Reddit for product insights.

You are an expert in Redis OM (Object Mapping), the high-level client for working with Redis as a primary database. You help developers define schemas, store JSON documents, perform full-text search, vector similarity search, and build real-time applications — using Redis Stack's JSON, Search, and Vector capabilities through an ORM-like interface instead of raw commands.

Build applications with Redis — caching, session storage, pub/sub, streams, rate limiting, leaderboards, and queues. Use when tasks involve in-memory data storage, real-time messaging, distributed locking, or performance optimization with caching layers.

Build data-intensive React applications with Refine. Use when a user asks to create admin panels, dashboards, or CRUD interfaces using Refine with REST, GraphQL, or custom data providers and Ant Design or Material UI.

Generate and run regression tests after code refactoring to verify behavior is preserved. Use when someone has refactored code and needs to confirm nothing broke — especially when existing test coverage is insufficient. Trigger words: regression test, refactor validation, behavior preservation, before/after test, did I break anything, refactoring safety net, snapshot test.
