Skill UI

Expert TDD orchestrator for enforcing red-green-refactor discipline, coordinating multi-agent workflows, and applying modern test-driven development practices across software projects. Covers test suite architecture, AI-assisted test generation, metrics, and framework integration.

This skill acts as an alias for the canonical TDD workflow cycle. It assists developers in implementing Test-Driven Development methodologies by structuring testing cycles and ensuring quality assurance. Use it when working on software development tasks requiring a test-first approach. It redirects to the full TDD cycle implementation for detailed guidance on writing tests before code.

Expert in building Telegram Mini Apps (TWA) - web apps that run inside Telegram with native-like experience. Covers TON ecosystem, Telegram Web App API, payments, user authentication, and viral monetization.

This skill provides pre-configured project scaffolding templates for initiating new applications from scratch. It covers 12 diverse technology stacks including Next.js, Express, Python FastAPI, React Native, Flutter, and more. Users can select the appropriate template based on their project type, such as full-stack web apps, APIs, mobile applications, or desktop software. It streamlines the setup process by offering ready-made structures and configurations tailored to specific development needs.

This skill provides comprehensive testing approaches for Temporal workflows using pytest. It covers unit testing with time-skipping, integration testing with mocked activities, and replay testing for determinism validation. Resources guide local development setup, CI/CD integration, and achieving high code coverage targets. Ideal for validating Python SDK workflows efficiently.

This skill guide provides comprehensive implementation details for the Metro/Modern UI style, mimicking the aesthetic of Windows Phone/8 start screens. It focuses on creating sharply cornered, flat-color tiles arranged in a horizontally scrolling grid. Key features include live data updates (e.g., tile flipping) and replicating the classic interactive 'tilt' effect. Applicable for cross-platform development using Web (CSS), iOS (SwiftUI), and Flutter.

This skill generates appropriate user feedback states for components and pages, including loading skeletons, empty states, error messages, and success toasts. It ensures consistent UI presentation by implementing specific design patterns for data-dependent areas, handling partial or full failures, and providing retry mechanisms. It follows design language references for animations and accessibility, suitable for React-based frontend development workflows.

An expert guide for developing production-grade AI applications, chatbots, and generative UIs using the Vercel AI SDK, Next.js, and React. Covers core concepts including streaming text (`streamText`), managing chat state (`useChat`), implementing complex tool/function calling, and ensuring robust structured data generation (JSON schemas) across multiple LLM providers.

Expert in building voice AI applications - from real-time voice agents to voice-enabled apps. Covers OpenAI Realtime API, Vapi, Deepgram, ElevenLabs, LiveKit, and WebRTC. Focuses on low-latency, production-ready voice experiences.

Build real-time conversational AI voice engines using async worker pipelines, streaming transcription, LLM agents, and TTS synthesis with interrupt handling and multi-provider support. Ideal for creating voice assistants, customer service agents, and voice-enabled applications that process streaming audio and integrate multiple AI providers effectively.

This masterclass framework provides a structured, end-to-end guide for scoping and planning new web projects, applications, or page designs. It systematically covers core concept definition, user experience (UX) mapping, visual design system establishment, selecting the technical architecture, and optimizing for SEO and performance. Ideal for the initial stages of development.

This guide details the principles and technical implementation of widget-based user interfaces, mimicking the aesthetic of modern mobile operating systems (like iOS Home Screen). It covers core design principles such as strict aspect ratios, glanceability, and corner radius matching. Practical code examples are provided for Web (CSS Grid), iOS (SwiftUI), and Cross-platform (Flutter) development, enabling designers to create modular, highly functional mini-apps.
