Skill UI

This skill generates appropriate user feedback states for components and pages, including loading skeletons, empty states, error messages, and success toasts. It ensures consistent UI presentation by implementing specific design patterns for data-dependent areas, handling partial or full failures, and providing retry mechanisms. It follows design language references for animations and accessibility, suitable for React-based frontend development workflows.

Generates comprehensive technical documentation pages with evidence-based depth, including Mermaid diagrams, citations, and VitePress frontmatter. Ideal for documenting components, systems, or features with traceable code paths.

Answer repository questions grounded entirely in source code evidence. Searches and reads relevant files, then synthesizes answers with inline citations. Useful for understanding specific files, functions, or components, and for answering how or where questions about the codebase.

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 enables developers to create Zustand stores following established patterns with proper TypeScript types and middleware. It provides templates for separating state and actions, using individual selectors, and subscribing outside React components. Ideal for React frontend development projects requiring robust state management solutions with type safety and best practices.

Designs payroll register templates capturing employee, department, salary components, deductions, and net pay. Produces CSV, SQL, JSON, or Notion outputs on request, without performing payroll calculations.

Turn a screenshot or mockup into matching UI using the project's own components, then compare side by side and fix differences. Ideal for frontend developers and designers who need pixel-accurate implementation from images.

Write or update a project's DESIGN.md from the colors, type, spacing and components it really uses, with rules agents follow so new screens match. It helps create a single source of truth for UI consistency.
