Skill UI

This skill acts as an expert in code refactoring, specializing in clean code principles, SOLID design patterns, and modern software engineering best practices. It analyzes existing code to improve its quality, reduce complexity, and enhance maintainability. Use it for refactoring tangled sections, eliminating code smells, improving testability, and safely preparing modules for new features while ensuring behavior remains stable.

Analyzes diffs, architecture, and tests to spot bugs, SQL injection, XSS, N+1 queries, and maintainability smells, then produces prioritized, actionable reports ideal for PR reviews, quality audits, and refactoring planning.

Runs the Centinela QA agent to scan for dead code, tech debt, outdated or vulnerable dependencies, code smells, and TODO/FIXME audit results, generating a documented report for release or refactor readiness.

This skill provides a comprehensive audit workflow for diagnosing performance issues in SwiftUI applications. It begins with a code-first review, identifying common performance smells like invalidation storms or layout thrash. If code inspection is insufficient, it guides the user through collecting runtime profiling evidence (e.g., Instruments data) to pinpoint root causes such as janky scrolling, high CPU usage, or memory leaks.

This skill provides comprehensive guidelines and techniques for safe code refactoring. It focuses on improving code structure, readability, and maintainability without altering the external behavior or functionality of the system. Learn to address common code smells, such as long methods, duplicated logic, god objects, and primitive obsession, using established design patterns and best practices. It emphasizes that refactoring should be gradual, test-driven, and methodical.
