Guide for using Docker - a containerization platform for building, running, and deploying applications in isolated containers. Use when containerizing applications, creating Dockerfiles, working with Docker Compose, managing images/containers, configuring networking and storage, optimizing builds, deploying to production, or implementing CI/CD pipelines with Docker.

Expert guide for implementing NuxtUI v4.1+ - an open-source UI library of 100+ customizable components built with Tailwind CSS and Reka UI. Use when the user mentions NuxtUI components (UButton, UInput, UCard, etc.), asks about implementing UI features, needs component examples, works with forms/layouts/navigation, or requests theme/styling customization. Proactively suggest when building UI to ensure consistent design. (project)

Convert a rough MVP idea into a demo-grade PRD (Steps 1-7)

Use when translating PRDs, feature specs, or product requirements into UX specifications for mockup tools like Google Stitch, Figma, or similar. Use before creating visual designs, wireframes, or component specs.

Use when building React UIs with component libraries, implementing forms, dialogs, navigation, or data display. Use when user mentions shadcn, Radix UI, Base UI, or asks about accessible React components. Proactively suggest when building UI that would benefit from pre-built accessible components with Tailwind CSS styling.

Guide for building applications on Cloudflare's edge platform. Use when implementing serverless functions (Workers), edge databases (D1), storage (R2, KV), real-time apps (Durable Objects), AI features (Workers AI, AI Gateway), static sites (Pages), or any edge computing solutions.

Guide for implementing Cloudflare R2 - S3-compatible object storage with zero egress fees. Use when implementing file storage, uploads/downloads, data migration to/from R2, configuring buckets, integrating with Workers, or working with R2 APIs and SDKs.

Refine and clarify PRD documentation through structured questioning using the visual AskUserQuestion tool

Comprehensive guide for PostgreSQL psql - the interactive terminal client for PostgreSQL. Use when connecting to PostgreSQL databases, executing queries, managing databases/tables, configuring connection options, formatting output, writing scripts, managing transactions, and using advanced psql features for database administration and development.

Comprehensive guide for building serverless applications with Cloudflare Workers. Use when developing Workers, configuring bindings, implementing runtime APIs, testing Workers, using Wrangler CLI, deploying to production, or building edge functions with JavaScript/TypeScript/Python/Rust.

Use when translating UX specifications into build-order prompts for UI generation tools. Triggers when user has a UX spec, PRD, or detailed feature doc and needs sequential, self-contained prompts for tools like v0, Bolt, or Claude frontend-design.

Transform an OpenSpec change phase into UI-ready build prompts through a 3-step pipeline. PRD generation, then UX specification, then build-order prompts. Use when starting implementation of an OpenSpec feature phase, or when the user mentions "openspec-to-prompts", "feature pipeline", or asks to convert a spec phase to implementation prompts. Requires an openspec change-id and phase number as input.

Validate at every layer data passes through to make bugs impossible

Test at extremes (1000x bigger/smaller, instant/year-long) to expose fundamental truths hidden at normal scales

Dispatch to the right problem-solving technique based on how you're stuck

Guide for implementing Cloudflare Browser Rendering - a headless browser automation API for screenshots, PDFs, web scraping, and testing. Use when automating browsers, taking screenshots, generating PDFs, scraping dynamic content, extracting structured data, or testing web applications. Supports REST API, Workers Bindings (Puppeteer/Playwright), MCP servers, and AI-powered automation. (project)

Systematically trace bugs backward through call stack to find original trigger

Four-phase debugging framework that ensures root cause investigation before attempting fixes. Never jump to solutions.

Flip core assumptions to reveal hidden constraints and alternative approaches - "what if the opposite were true?"

Force unrelated concepts together to discover emergent properties - "What if we treated X like Y?"

Run verification commands and confirm output before claiming success

Spot patterns appearing in 3+ domains to find universal principles
