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.

Browse and search Reddit via the public JSON API with no authentication required. Use when a user asks to read Reddit, browse a subreddit, fetch Reddit posts, get Reddit comments, search Reddit for posts, check trending topics on Reddit, read a Reddit thread, or pull content from a subreddit.

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.

Trigger words: remix, remix run, loader, action, useFetcher, nested routes, progressive enhancement.

Programmatic video creation with React using Remotion. Use when a user asks to create videos with code, generate personalized videos, build animated data visualizations, add TikTok-style captions, render video programmatically, or automate video production. Supports CLI rendering, AWS Lambda, and Google Cloud Run deployment.

Expert guidance for Render, the modern cloud platform for deploying web applications, APIs, databases, and background workers. Helps developers configure Render services using `render.yaml` Infrastructure as Code, set up auto-deploy from Git, manage environment variables, and optimize for production workloads.

Assists with automating dependency updates across JavaScript, Python, Docker, Go, Rust, Terraform, and 50+ ecosystems using Renovate. Use when configuring update strategies, automerge policies, grouping rules, or scheduling to keep dependencies current. Trigger words: renovate, dependency updates, automerge, package rules, dependency management.

Generate professional reports with charts, tables, visualizations, and structured narratives. Covers data-driven PDF/HTML reports, weekly status reports, executive summaries, and recurring team updates. Use when a user asks to create a report, generate a data report, build a dashboard report, write a weekly report, create a status update, or produce a team progress report.

Create a detailed refactor plan with tiny commits via user interview, then file it as a GitHub issue. Use when: user wants to plan a refactor, create a refactoring RFC, or break a refactor into safe incremental steps.

You are an expert in Resend, the developer-first email API. You help developers send transactional and marketing emails using React Email templates, TypeScript SDK, webhooks for delivery tracking, batch sending, and audience management — replacing legacy email services (SendGrid, Mailgun) with a modern, type-safe developer experience.

Design and build RESTful APIs. Use when a user asks to create a REST API, design API endpoints, implement CRUD operations, add authentication to an API, handle pagination and filtering, set up API versioning, generate OpenAPI/Swagger docs, implement rate limiting, build middleware, handle file uploads, add CORS, implement HATEOAS, or structure an Express/Fastify/Koa/Flask/FastAPI backend. Covers HTTP methods, status codes, resource modeling, error handling, validation, and production deployment patterns.

Use when someone asks to "durable execution", "Restate", "resilient workflows", "distributed transactions", "saga pattern", "fault-tolerant services", or "replace Temporal with something lighter". Covers durable handlers, virtual objects, workflows, and sagas.

Back up and restore data with Restic. Use when a user asks to set up backups, create encrypted backups, back up to S3 or cloud storage, implement a backup strategy, restore files from backup, deduplicate backup storage, schedule automated backups, back up databases or servers, or set up offsite backups. Covers repository initialization, backup/restore operations, snapshot management, pruning, encryption, and multiple storage backends (local, S3, SFTP, B2, Azure, GCS).
