Skill UI

This skill generates Robot Framework tests using keyword-driven syntax with Python. It supports SeleniumLibrary for web UI testing and RequestsLibrary for API testing. Users can define custom keywords and create data-driven test cases. Ideal for automation engineers needing structured test scripts for web applications and backend services. Supports cloud integration and CI/CD pipelines.

This skill specializes in scaffolding production-ready Rust applications. It generates complete project structures using Cargo tooling, ensuring proper module organization, testing setup, and configuration following Rust best practices. It supports binary, library, workspace, and web API project types with idiomatic code patterns.

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.

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.

Assay is a local testing tool that opens web pages in a real browser to interact with all controls. It reports inconsistencies without needing an API key or network. Use it after creating or modifying HTML pages to verify functionality and ensure stability before deployment.

This skill helps design and review API contract tests between providers and consumers. It focuses on verifying wire-level behavior during schema changes, compatibility regressions, and client integration failures. By using local fixtures and existing tools, it ensures type assertions alone are not validation. It classifies changes as breaking or compatible, builds test matrices for various scenarios, and verifies boundaries without provisioning new services.
