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.
