Skill UI

Expert in building Telegram bots that solve real problems - from simple automation to complex AI-powered bots. Covers bot architecture, the Telegram Bot API, user experience, monetization strategies, and scaling bots to thousands of users.

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.

Migrates and converts test automation scripts between Selenium, Playwright, Puppeteer, and Cypress. Applies API mappings, lifecycle changes, and pattern conversions to port tests seamlessly.

Sweep the googleapis/mcp-toolbox docs for broken and non-canonical links, report each finding with its cause, and apply the safe class of internal link fixes. CI does not check links on this repo, so this skill is the only link check that runs. Use when a maintainer asks for a link sweep or a docs health check, before a release, or after a docs reorg, page rename, or directory move. The skill edits the working tree and makes one commit. It never pushes, never opens a PR, and never rewrites external links or ambiguous targets.

Detects which APIs of a Python project's pinned dependencies changed after a coding model's training cutoff, locates the code using them, and writes short evidence-tagged notes into AGENTS.md or CLAUDE.md.

This skill enables building production-ready analytic and bounded water systems in Three.js. It covers photorealistic shallow water simulation using gravity-capillary FFT waves, dispersive caustics, ray-traced volume optics, and Beer-Lambert absorption. Ideal for creating realistic pool, ocean, and water surface effects with accurate normals, refraction, and foam generation.

This skill automatically routes subtasks to the most cost-effective Claude model (Haiku, Sonnet, or Opus) based on complexity. It logs real token usage and cost per session, and includes an A/B testing feature to validate model tier savings against your actual workload, ensuring accurate cost control.

tRPC allows developers to build highly type-safe APIs in a full-stack environment without needing to write or maintain separate schemas. It provides end-to-end type safety from server routers to client components, supporting queries, mutations, subscriptions, and robust middleware. Ideal for building modern TypeScript monorepos, Next.js, or Remix applications.

Build communication features using Twilio APIs for SMS, voice calls, WhatsApp Business, and 2FA verification. Supports IVR systems and multi-channel authentication. Essential for integrating programmable messaging and phone verification into applications.

Comprehensive guidance for mastering advanced TypeScript type features, including generics, conditional types, mapped types, and utility types. This skill is essential for building robust, maintainable, and highly type-safe applications, such as large-scale libraries, complex API clients, and advanced state management solutions.
