Skill UI

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.

Automates TikTok content creation via Rube MCP (Composio) by uploading videos/photos, managing published posts, and checking profile stats through the toolkit’s sequence of upload, publish, status polling, and profile APIs.

This skill provides advanced guidelines for designing robust and effective tools specifically for autonomous AI agents. It shifts the focus from traditional developer APIs to contracts optimized for Language Models (LLMs). Key topics covered include treating tool descriptions as prompt engineering, implementing namespacing, applying the Consolidation Principle, and utilizing Architectural Reduction patterns (like file system access) to maximize agent reliability and workflow complexity.

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.

Scan Apple's SwiftUI documentation via the Sosumi MCP to find deprecated APIs and their modern replacements, then update the SwiftUI Expert Skill reference file and open a pull request.

Generates Vitest tests in JavaScript/TypeScript with Vite-native speed. Covers Jest-compatible APIs, vi.mock mocking, spies, fake timers, snapshots, React component tests, in-source testing, and vitest.config setup.

A comprehensive guide covering the entire lifecycle of building VS Code extensions, from initial scaffolding to successful Marketplace publication. Learn best practices for Webviews, TreeViews, testing, packaging, and troubleshooting, ensuring compatibility with the latest APIs.

Retrieve surface and upper-air weather observations from NOAA APIs and archives, preserving station identity, time, units, and quality flags. Covers METARs, ISD, IGRA radiosondes, and station metadata for analysis-ready data.

A powerful utility that queries multiple free APIs (Pexels, Pixabay, Internet Archive, etc.) in a single query. It retrieves normalized, license-tagged results for real-world, historical, or archival images, videos, and GIFs, making it a peer to local semantic search and generative media tools. Includes specialized scripts for fetching and judging audio.

Official M2MCent wrapper for injecting x402 paywalls into Node.js/Express APIs or Model Context Protocol (MCP) servers. Enables machine-to-machine monetization by requiring USDC micropayments on Base L2. Includes middleware for Express routes and handles settlement automatically.

Audit an existing Cypress suite for flake-prone anti-patterns such as fixed cy.wait() delays, force: true, and APIs removed in Cypress 12-16. Provides a zero-dependency scanner and step-by-step fixes to stabilize tests without hiding failures behind retries or longer timeouts. Use when asked to fix flaky Cypress tests, remove cy.wait, or prepare for Cypress upgrades.
