UI Components
Code-based UI component generation and styling
convert-blazor-server-to-webapp
by dotnet
Guides conversion of a pre-.NET 8 Blazor Server app into a .NET 8+ Blazor Web App. USE FOR: migrating apps that use AddServerSideBlazor and MapBlazorHub to the AddRazorComponents/MapRazorComponents model, converting _Host.cshtml to an App.razor root component, replacing blazor.server.js with blazor.web.js, migrating CascadingAuthenticationState to a service, adopting new Blazor Web App features like enhanced navigation and streaming rendering. DO NOT USE FOR: apps that are already Blazor Web Apps (already use AddRazorComponents and MapRazorComponents), Blazor WebAssembly or hosted Blazor WebAssembly apps (different migration path), apps that should stay on the Blazor Server hosting model without converting, or apps still targeting .NET Framework.
configure-auth
by dotnet
Add authentication and authorization to a Blazor Web App, accounting for the app's render mode. USE WHEN the user needs [Authorize] on pages, AuthorizeView, role or policy-based access, login/logout Identity pages, or AuthenticationStateProvider. Also USE WHEN auth state is null after WebAssembly loads, SignInManager throws in an interactive component, <NotAuthorized> content never renders in static SSR, or HttpContext.User is null in an interactive component. DO NOT USE for general component authoring (see author-component), for prerendering concerns unrelated to auth (see support-prerendering), or for managing non-auth cascading state (see coordinate-components).
coordinate-components
by dotnet
Share state between components that don't have a direct parent-child parameter relationship, using cascading values, scoped services with change events, or CascadingValueSource via DI. USE WHEN the user needs a CascadingParameter or CascadingValue that works across render mode boundaries, a shopping cart or notification count accessible from multiple pages, a theme or user preference cascaded app-wide, or when components in different parts of the tree must react when shared data changes. Also USE WHEN cascading values aren't reaching interactive children in per-page interactivity mode, or when the user needs to understand scoped vs singleton service lifetime for state on Blazor Server. DO NOT USE for direct parent-child parameter passing or EventCallback (see author-component), for persisting state across prerender-to-interactive transitions (see support-prerendering), or for service abstractions for data fetching in Auto/WebAssembly (see fetch-and-send-data).
thesys-c1-genui

Frontend development patterns for React, Next.js, state management, performance optimization, and UI best practices.
video-comparer
by daymade
This skill should be used when comparing two videos to analyze compression results or quality differences. Generates interactive HTML reports with quality metrics (PSNR, SSIM) and frame-by-frame visual comparisons. Triggers when users mention "compare videos", "video quality", "compression analysis", "before/after compression", or request quality assessment of compressed videos.
evaluation-rubrics
by lyndonkl
Use when need explicit quality criteria and scoring scales to evaluate work consistently, compare alternatives objectively, set acceptance thresholds, reduce subjective bias, or when user mentions rubric, scoring criteria, quality standards, evaluation framework, inter-rater reliability, or grade/assess work.
firebase-app-hosting-basics
by firebase
Deploy and manage web apps with Firebase App Hosting. Use this skill when deploying Next.js/Angular apps with backends.
design-of-experiments
by lyndonkl
Use when optimizing multi-factor systems with limited experimental budget, screening many variables to find the vital few, discovering interactions between parameters, mapping response surfaces for peak performance, validating robustness to noise factors, or when users mention factorial designs, A/B/n testing, parameter tuning, process optimization, or experimental efficiency.
typescript-strict
by BlackBeltTechnology
TypeScript strict mode patterns with interfaces, type guards, generics, and utility types. Use when defining types, creating type-safe functions, handling nullable values, or implementing generic components.
component-architecture
by BlackBeltTechnology
Reusable component patterns for cards, sections, forms, and layouts with consistent prop interfaces and composition strategies. Use when creating new components, refactoring existing ones, or establishing component design patterns.
canvas-webapp
by BlackBeltTechnology
Render a React/Vite (or any bundled) web app on the pi-dashboard canvas, which loads loopback URLs in a sandboxed opaque-origin iframe. Use when a canvas(target:{kind:"url" "server"}) target shows up blank white, an empty surface, or a /live/<id> 500 ECONNREFUSED. Covers why Vite dev servers and non-CORS static servers fail there, and the static-build + CORS-server recipe that works.
zod-react-hook-form
by BlackBeltTechnology
Form validation combining Zod schemas with React Hook Form, including localized error messages, Server Action integration, and shadcn/ui Form components. Use when building forms, validating user input, handling form submissions, or implementing Server Actions with validation.
openforms-mui
by BlackBeltTechnology
Author, render, preview and debug OpenForms FormSchemaJSON form definitions as idiomatic, themed, accessible MUI (React). Use when the user wants to design an OpenForms form, render an OpenForms schema with Material UI, convert an OpenForms JSON schema into a React MUI form, preview a form schema, or debug conditional-logic / calculated fields / cross-field validation in an OpenForms schema. This is the OpenForms form-builder schema (github.com/henriquefps/open-forms) — NOT the "open-form.dev" documents-as-code framework, which this skill does not cover.
tailwind-shadcn
by BlackBeltTechnology
Tailwind CSS utility patterns with shadcn/ui component usage, theming via CSS variables, and responsive design. Use when styling components, installing shadcn components, implementing dark mode, or creating consistent design systems.
rebuild-package-diagrams
by BlackBeltTechnology
Render a reverse-spec rebuild package as traced, script-checked visuals — a Mermaid ER diagram of model.md entities, capability use cases as BPMN processes, and one browsable HTML catalog. Use on "ER diagram from the entities", "draw the data model", "use cases as BPMN", "browsable HTML of the rebuild package", "ER diagram az entitásokból", "üzleti folyamat BPMN-ben".
design-ui

Provides design direction and visual system for web UI. Defines layout, typography, colour, and overall aesthetic for product (SaaS/admin/data-heavy) or marketing/brand experiences. Use when choosing visual direction, selecting colour palettes and fonts, establishing layout patterns, or starting a new UI design system.
implement-frontend
by mblode
Standards for implementing and reviewing React/TypeScript/Next.js features in codebases that use React Hook Form, Zod, React Query or Connect Query, and proto-generated API types. Use when building frontend forms, hooks/components, state flows, and type-safe UI mappings in this stack.
decomposition-reconstruction
by lyndonkl
Use when dealing with complex systems that need simplification, identifying bottlenecks or critical failure points, redesigning architecture or processes for better performance, breaking down problems that feel overwhelming, analyzing dependencies to understand ripple effects, user mentions "this is too complex", "where's the bottleneck", "how do we redesign this", "what are the key components", or when optimization requires understanding how parts interact.
theme-system
by BlackBeltTechnology
CSS custom properties theme architecture for 4 themes (studio, earth, athlete, gradient) with data-theme attribute switching and theme-aware components. Use when implementing theme switching, defining color schemes, or creating theme-responsive UI elements.

Use when user says "code connect", "connect this component to code", "connect Figma to code", "map this component", "link component to code", "create code connect mapping", "add code connect", "connect design to code", or wants to establish mappings between Figma designs and code implementations. Requires Figma MCP server connection.
visual-explainer
by nicobailon
Generate beautiful, self-contained HTML pages that visually explain systems, code changes, plans, and data. Use when the user asks for a diagram, architecture overview, diff review, plan review, project recap, comparison table, or any visual explanation of technical concepts. Also use proactively when you are about to render a complex ASCII table (4+ rows or 3+ columns) — present it as a styled HTML page instead.
