Neon + Vercel serverless Postgres for edge and serverless environments. Use for Cloudflare Workers, Vercel Edge, Next.js apps with HTTP/WebSocket connections, database branching (git-like), Drizzle/Prisma ORM integration, migrations, PITR backups, or encountering connection pool exhausted errors, TCP connection issues, SSL config problems.
Ktor framework - routing, authentication, WebSockets
Integrate Duit framework into Flutter applications including setup, driver configuration, HTTP/WebSocket transports, custom widgets, and themes. Use when integrating backend-driven UI, configuring Duit, or adding Duit to Flutter applications.
Build high-performance async APIs with FastAPI, SQLAlchemy 2.0, and Pydantic V2. Master microservices, WebSockets, and modern Python async patterns. Use PROACTIVELY for FastAPI development, async optimization, or API architecture.
Complete reference for HTMX — the HTML-first library for modern browser features without JavaScript. Use when tasks involve hx-* attributes, HTMX AJAX requests, swap strategies, server-sent events, WebSockets, or hypermedia-driven UIs.
Build AI agents with Cloudflare Agents SDK on Workers + Durable Objects. Includes critical guidance on choosing between Agents SDK (infrastructure/state) vs AI SDK (simpler flows). Use when: deciding SDK choice, building WebSocket agents with state, RAG with Vectorize, MCP servers, multi-agent orchestration, or troubleshooting "Agent class must extend", "new_sqlite_classes", binding errors.
Cover Stimulus controller fundamentals: lifecycle hooks, values and valueChanged callbacks, targets and target callbacks, outlets, action parameters, keyboard events, and controller architecture patterns. Prefer this skill when the request is primarily about Stimulus APIs and controller design independent of a specific Hotwire domain. Use hwc-forms-validation for form-specific workflows, hwc-navigation-content for Turbo navigation concerns, hwc-realtime-streaming for Turbo Streams/WebSocket patterns, hwc-media-content for media integrations, and hwc-ux-feedback for loading/progress/transition UX patterns.
Build Hotwire navigation and content-discovery flows: Turbo Frame pagination, tabbed navigation, lazy loading, faceted filtering/search, cache lifecycle, scroll restoration, and visit/render control. Prefer this skill when the core problem is request/response navigation state and browser history behavior. Use hwc-forms-validation for form validation and inline edit flows, hwc-realtime-streaming for WebSocket/Turbo Stream push updates, hwc-media-content for image/video/audio features, hwc-ux-feedback for generic loading/progress/transition polish, and hwc-stimulus-fundamentals for Stimulus APIs not centered on navigation.
Handle Hotwire form workflows: form submission lifecycle, inline editing, validation errors, typeahead/autocomplete, modal forms, and external form controls. Prefer this skill when the core problem is correctness and UX of form interaction. Use hwc-navigation-content for pagination/tabs/filter navigation, hwc-realtime-streaming for WebSocket/Turbo Stream broadcasting, hwc-media-content for image/video/audio behavior, hwc-ux-feedback for generic loading/transition polish, and hwc-stimulus-fundamentals for framework-level Stimulus APIs not tied to forms.
Provides comprehensive guidance for NestJS using the official documentation. Use when the user asks about NestJS architecture, controllers, providers, modules, middleware, guards, pipes, interceptors, dependency injection, GraphQL, WebSockets, microservices, OpenAPI/Swagger, security, or testing.
Optimize web performance through network protocols, resource loading, and browser rendering internals. Use when the user mentions "page load speed", "Core Web Vitals", "HTTP/2", "resource hints", "network latency", or "render blocking". Covers TCP/TLS optimization, caching strategies, WebSocket/SSE, and protocol selection. For UI visual performance, see refactoring-ui. For font loading, see web-typography.
Provides 3-tier validation approach for Home Assistant dashboards including pre-publish validation (entity checks, config structure), post-publish verification (log analysis), and visual validation (browser console, rendering). Use when validating HA dashboards, checking dashboard configs, verifying entity IDs, debugging rendering issues, or before deploying dashboard changes. Triggers on "validate dashboard", "check HA config", "dashboard errors", "entity not found", or "test dashboard". Works with Home Assistant WebSocket/REST APIs, Chrome extension MCP tools, Python dashboard builders, and YAML dashboard configurations.
