Web & Frontend

serkan-ozal Skill

Automated browser testing and debugging using Browser DevTools MCP. Use when testing web pages, debugging frontend issues, verifying UI behavior, or automating browser interactions.

igniteui Bundle

Covers all non-grid Ignite UI for Angular UI components: application scaffolding and setup, form controls (inputs, combos, selects, date/time pickers, calendar, checkbox, radio, switch, slider), layout containers (tabs, stepper, accordion, splitter, navigation drawer), data-display components (list, tree, card, chips, carousel, paginator, progress indicators, chat), feedback overlays (dialog, snackbar, toast, banner), directives (button, icon button, button group, ripple, tooltip, drag-and-drop), Dock Manager, Layout Manager, Tile Manager, and Charts. Use when users ask about any Ignite UI Angular component that is NOT a data grid — such as forms, dropdowns, pickers, dialogs, navigation, lists, trees, cards, charts, or initial project setup. Do NOT use for data grids, tables, or tabular data — use igniteui-angular-grids instead. Do NOT use for theming or styling — use igniteui-angular-theming instead.

modelengine-group Bundle

Workflow for generating form JSON and using the Svelte Form Builder (svelte-form-builder.vercel.app) to scaffold SvelteKit remote function forms with Valibot validation. Use when creating forms via the form builder.

linuxfoundation Skill

Pre-PR validation — working tree status, format, lint, TypeScript check, and protected file check. Workspace-aware: detects which of backend/, frontend/, services/apps/*, services/libs/* were changed and runs only the relevant scripts. Use before submitting any PR, to check if code is ready, or to validate a branch before review.

unreadlogs Bundle

Use this skill whenever the user wants to create, validate, render, analyze, or repair Mermaid diagrams. It validates Mermaid syntax (reporting errors with line numbers), renders diagrams to SVG/PNG/JPG/PDF/HTML, computes graph stats (nodes, edges, actors, tasks, states, etc.), extracts mermaid code blocks from Markdown documents, and fixes common formatting issues. If the user pastes Mermaid code, wants a diagram image, or needs diagram code fixed, use this skill.

wilswu99 Bundle

Render a conversation message or Markdown with typeset LaTeX equations as a local HTML page in a new qutebrowser window. Use when Wilson asks to render an answer or read it outside the terminal. Automatically render assistant messages containing more than one equation only in local GUI sessions with qutebrowser available; skip automatic rendering over SSH or without a display.

wpgaurav Bundle

get-convex Bundle

Initializes a new Convex project from scratch or adds Convex to an existing app. Use this skill when starting a new project with Convex, scaffolding with npm create convex@latest, adding Convex to an existing React, Next.js, Vue, Svelte, or other frontend, wiring up ConvexProvider, configuring environment variables for the deployment URL, or running npx convex dev for the first time, even if the user just says "set up Convex" or "add a backend."

get-convex Bundle

Designs and builds Convex components with isolated tables, clear boundaries, and app-facing wrappers. Use this skill when creating a new Convex component, extracting reusable backend logic into a component, building a third-party integration that owns its own tables, packaging Convex functionality for reuse, or when the user mentions defineComponent, app.use, ComponentApi, ctx.runQuery/runMutation across component boundaries, or wants to separate concerns into isolated Convex modules.

get-convex Bundle

Plans and executes safe Convex schema and data migrations using the widen-migrate-narrow workflow and the @convex-dev/migrations component. Use this skill when a deployment fails schema validation, existing documents need backfilling, fields need adding or removing or changing type, tables need splitting or merging, or a zero-downtime migration strategy is needed. Also use when the user mentions breaking schema changes, multi-deploy rollouts, or data transformations on existing Convex tables.

igniteui Bundle

Pick, install, and use Ignite UI for React (Igr*) components — package routing, theme CSS, JSX and slots, events, refs, forms, TypeScript, charts/gauges/maps, grids. Use when choosing a component for a UI pattern, setting up igniteui-react, writing Igr* JSX, wiring events or refs, or debugging components that render unstyled, invisible, or with broken icons.

igniteui Bundle

Theme Ignite UI for React with CSS custom properties — brand palette, dark mode, size/spacing/roundness, per-component tokens, and scoped themes, optionally via the igniteui-theming MCP server. Use when applying brand colors, switching light/dark, overriding a component's appearance (grid headers, buttons, avatars), or when theme overrides are not taking effect.

igniteui Skill

Reduce bundle size in apps using Ignite UI for React — package selection, tree-shaking, and route-level code splitting of grids, charts, maps, and gauges. Use when the bundle or initial load is too large, when tree-shaking is not eliminating unused Ignite UI code, or when deciding what to lazy load.

igniteui Bundle

Build a React view from a design image (screenshot, mockup, wireframe) using Ignite UI for React components and generated theme tokens. Use when the user supplies an image and asks to implement this design, build this UI, convert this mockup, or create a page from this screenshot in an Ignite UI React project.

jazzenchen Skill

x0ba Skill

When the user asks for an HTML write-up of work (NOT as part of the codebase)

jurybu Bundle

Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, artifacts, posters, or applications (examples include websites, landing pages, dashboards, React components, HTML/CSS layouts, or when styling/beautifying any web UI). Generates creative, polished code and UI design that avoids generic AI aesthetics.

jurybu Bundle

Suite of tools for creating elaborate, multi-component claude.ai HTML artifacts using modern frontend web technologies (React, Tailwind CSS, shadcn/ui). Use for complex artifacts requiring state management, routing, or shadcn/ui components - not for simple single-file HTML/JSX artifacts.

levi0527 Bundle

A Codex Canvas is a live React app that the user can open beside the chat. You MUST use a canvas when the agent produces a standalone analytical artifact — quantitative analyses, billing investigations, security audits, architecture reviews, data-heavy content, timelines, charts, tables, interactive explorations, repeatable tools, or any response that benefits from visual layout. Especially prefer a canvas when presenting results from MCP tools (Datadog, Databricks, Linear, Sentry, Slack, etc.) where the data is the deliverable — render it in a rich canvas rather than dumping it into a markdown table or code block. If you catch yourself about to write a markdown table, stop and use a canvas instead. You MUST also read this skill whenever you create, edit, or debug any .canvas.tsx file.

davidortinau Bundle

Apply the foundational reasoning of a senior UI/UX designer to interface decisions — BEFORE and WHILE generating UI, not just styling it afterward. Use this skill whenever you are designing, structuring, or evaluating an application interface — choosing a layout, a navigation pattern, a flow, an affordance, how much to show at once, or how to group and prioritize elements. This is about design FIRST PRINCIPLES (visual hierarchy, cognitive load, Gestalt grouping, usability heuristics, accessibility) — the 'why' behind good design — NOT design EXECUTION (color tokens, fonts, spacing scales, brand systems, component libraries). Trigger it even when the user does not say 'principles' — phrases like 'design a screen for…', 'lay out this dashboard', 'what navigation should this app use', 'is this UI any good', 'structure this form', 'reduce clutter', or 'make this clearer' all warrant it. Composes alongside execution/styling skills — this one decides WHAT and WHY; those decide HOW it looks.

hmbown Skill
