Skill UI

This comprehensive workflow provides a complete cycle of quality assurance for software development. It covers every stage from defining the test strategy (TDD, Unit Testing) through integration, E2E testing, browser automation, performance profiling, security scanning, and final code review. Use this when setting up robust testing infrastructure or ensuring production-ready software quality.

Comprehensive guidelines for writing idiomatic and efficient TypeScript and JavaScript code. Covers array operations, destructuring, async patterns, type safety, React hooks, and common anti-patterns to improve code quality and maintainability.

This skill automates the creation of comprehensive unit tests across multiple programming languages like Python, JavaScript, and Java. It analyzes source code to identify functions and classes, then generates maintainable test suites with strong coverage, edge case handling, and proper mocking. Ideal for developers seeking consistent test structures and improved code quality without manual writing.

A comprehensive, multi-phase quality assurance tool designed for Next.js fullstack applications. It verifies production readiness by checking code integrity, build success, SEO metadata, API authentication, route stability, performance, and security vulnerabilities. Use it as a mandatory pre-deployment checklist before promoting an app to production.

This skill generates championship-grade test suites for any project using the WJTTC methodology. It analyzes the codebase, classifies components, and scaffolds executable test files. It emphasizes pre-defined test plans, inline testing, and two-layer testing architecture to ensure high code quality and signal integrity in CI/CD pipelines.

This skill provides a five-axis code review checklist covering correctness, security, readability, performance, and test coverage. It generates actionable comments rather than style nitpicks. Use it when reviewing code, diffs, or pull requests to ensure quality and safety.

Scores a project across four quality dimensions — PR quality, architecture, tech debt, and test quality — in one pass, producing a composite health score and dashboard report before releases or team onboarding.

This skill performs a full-sweep analysis across code decay, architecture, tech debt, and test quality. It applies fixes directly to the codebase with safety checks. Safe changes are auto-applied, while risky changes require confirmation. Based on twelve classic engineering books, it triggers when users want to fix everything or clean up the whole project in a single command.

Reviews existing test suites for structural problems like brittleness, mock abuse, coverage illusions, slow runs, and poor readability, drawing on twelve classic engineering books such as xUnit Test Patterns and Working Effectively with Legacy Code.
