Web & Frontend

xitssky Bundle

Use when writing or reviewing code in any stack. It captures the cross-cutting engineering baseline shared by frontend and backend work. Covers TypeScript and JavaScript conventions, the unit-testing contract, git and gitflow, clean-code principles, and a security baseline. Referenced by frontend-development and backend-development.

xitssky Bundle

Use when writing, reviewing, or refactoring frontend or UI code (components, pages, templates, styling, client-side state, forms, or accessibility) in Angular, React, Next.js, Vue, or plain TypeScript/JavaScript. Also use for frontend testing and client-side performance work.

xiaoy233 Skill

Customize documentation appearance and layouts using Fumadocs UI theme and component library

valdesrosier Bundle

Write or repair paste-ready HTML and CSS for ArcGIS Online Hub text cards and Map Viewer popups. Use when ordinary web markup is stripped, rejected, or rendered differently in either editor.

vechain Bundle

Scaffold a VeChain dApp with Next.js, VeChain Kit, Chakra UI v3, and GitHub Pages deployment. Supports standalone (frontend-only) or monorepo (Turbo + Hardhat contracts) modes. Use when creating a new VeChain project, scaffolding a dApp, setting up a VeChain frontend, or bootstrapping a VeChain monorepo.

westpacgel Bundle

Guides consumers of the @westpac/ui component library on correct usage, capabilities, and patterns. Use when asking how to use a GEL component, whether a component supports a feature, or how to implement a UI pattern with @westpac/ui.

westpacgel Bundle

React and Next.js performance optimization guidelines from Vercel Engineering. This skill should be used when writing, reviewing, or refactoring React/Next.js code to ensure optimal performance patterns. Triggers on tasks involving React components, Next.js pages, data fetching, bundle optimization, or performance improvements.

mauricioperera Skill

Patterns for consuming the img.automators.work placeholder image API via HTTP. Use when building HTML mockups, CSS backgrounds, or design prototypes that need SVG placeholder images of specific dimensions and colors.

skillmedev Skill

Drives a major-version framework bump as a sequence of small, reversible, CI-gated PRs using official codemods and changelog diffing while keeping the app green. Use when bumping React, Rails, Spring Boot, Angular, or any framework across a major version with breaking API/config changes; do NOT use for language or runtime version jumps (Python 2 to 3, Node majors, Java LTS) - use language-version-migrator instead.

skillmedev Skill

Ports a codebase across a breaking language or runtime version with compatibility shims, batched automated transforms, dual-runtime CI, and old-vs-new output diffing, ending in a flag-flip cutover with a rollback rule. Use when someone says "migrate us from Python 2 to 3", "we're jumping Node majors", "move to the next Java LTS", or any runtime upgrade where source must change to keep compiling or behaving correctly. Do NOT use for an application framework's major version (React, Rails, Spring) - use framework-upgrader instead; for proving a database schema or data migration is safe, use migration-safety-checker; and skip it entirely when the runtime change is purely operational (base image, CI matrix, deploy target) with no syntax or semantic breaks.

cloudcannon Bundle

Use when adding snippet support to a CloudCannon site, configuring MDX components for the Content Editor, debugging snippet round-trip issues, or setting up inline HTML snippets in markdown content.

cloudcannon Bundle

Get a site ready for Rosey translation, with the CloudCannon connector (RCC) as an optional visual-editing layer. Use when the user wants to add multilingual support, internationalize a site, set up Rosey, replace an existing i18n system (astro-i18n, next-intl, path-based routing, etc.), or upgrade from RCC v1 to v2.

jtenniswood Skill

Provide an expert codebase review for this repository. Use when the user says "Expert Review" or "/expert-review", asks for an expert review, wants refactoring or codebase improvement recommendations, wants consistency and quality assessed, or asks how to reduce duplication, improve component use, preserve the end-user experience, and keep upgrades cleanly migratable.

qingqishi Bundle

StyleX styling system with project-specific design tokens, composable primitives, and custom css prop. MUST consult this skill before writing or modifying ANY styles in this project — the codebase uses custom design tokens, flex primitives, motion presets, and a css prop that differs from standard StyleX. Trigger whenever the user asks to create components, modify visual appearance, fix spacing/layout, add hover/focus effects, animations, responsive behavior, or anything involving CSS, styling, design tokens, breakpoints, or the css prop.

qingqishi Bundle

Use this skill when the user is working with LyteNyte Grid (@1771technologies/lytenyte-pro or @1771technologies/lytenyte-core), a headless React data grid. Activate for tasks like: installing or licensing LyteNyte Grid, configuring columns or rows, building cell renderers or editors, adding filters or sort controls, grouping or aggregating rows, pivoting, exporting to CSV/Excel/Parquet/Arrow, row selection, cell range selection, theming or styling, TypeScript GridSpec patterns, server-side or tree data, annotations, cell notes, marching ants, row/column animations, row banding, scroll flash suppression, and any PRO component (SmartSelect, PillManager, Menu, Dialog, TreeView, RowGroupCell). Also activate when the user describes grid problems without naming the package — e.g. "my rows won't group", "cells aren't editable", "add a loading overlay", "pin this column", "the filter isn't working", "how do I export this table", "select a range of cells", "copy cells to clipboard", "build me a grid", "animate rows",

qingqishi Skill

Builds and publishes a throwaway HTML playground for one @tuja/ui component, where the user retunes it by eye against the real design tokens and exports the changes back for you to apply to the source. Use it only when the user asks for the playground by name, or asks to tweak a component's look themselves instead of describing it to you. Not for ordinary styling work — a change the user has already described goes straight into the source through the styling skill.

citiesskylinesmodding Bundle

Coherent Gameface (Cohtml) domain knowledge for the game-UI middleware that renders HTML/CSS/JS inside games (Cities: Skylines II and many others). Use when writing or debugging UI that runs in a Gameface view, when HTML/CSS/JS behaves differently in the game than in a browser, when checking whether a web feature exists in a game's Cohtml version, or when working with data-bind-* attributes or the engine JS API. Also the domain reference for skills that drive a Gameface UI via the game_* tools.

citiesskylinesmodding Bundle

The Cities: Skylines II mod UI discipline: the C#-to-JavaScript binding layer and the game's React frontend. Use when a mod needs a panel, button or overlay in the game's UI, when exposing C# state to the frontend or invoking C# from it, when injecting into the game's own component tree, when a UI mod's bundle does not load or its styles do not apply, or when checking what the game's frontend already provides.

citiesskylinesmodding Skill

Operating manual for driving a live Gameface UI with the game_* MCP tools: procedures and traps. Load before first use of the input tools (game_click, game_fill, game_type, game_key, game_hover) or of any game_debug_* tool. Also use when verifying UI changes against a running game, when waiting for a mod rebuild to go live in-game, or when a game_* call fails or returns puzzling results. Engine support questions (does this CSS/JS/layout feature exist) belong to the gameface skill.

punpun1643 Bundle

Open a generated cognitive-map webpage in the local browser. Use when the user asks to open, launch, view, browse, or reopen a cognitive map, including requests such as "open the map", "show the cognitive map", or "launch map.html". Resolve the current project's map automatically or accept an explicit HTML, Markdown, or directory path.

agricidaniel Bundle

Scaffold and operate Gogh, a source-cited Obsidian brain for design skill stack advice across six frontend design skills: taste-skill v2, make-interfaces-feel-better, Impeccable, Anthropic frontend-design, ui-ux-pro-max, and Vercel web-design-guidelines. Use when the user says "gogh", "design skill stack", "anti-slop frontend", "which design skill", "stack design skills", any of the six skill names, or wants stack recommendations, conflict resolution, unified anti-slop rules, audits, or a maintained vault-backed design skill brain.

amirtaherkhani Bundle

Designs and reviews NestJS application architecture using cohesive feature modules, modular monoliths, layered or hexagonal boundaries, dependency inversion, and pragmatic engineering principles. Use when planning a NestJS project, changing module boundaries, evaluating Clean Architecture or DDD, resolving circular dependencies, defining ports and adapters, reviewing coupling, or deciding whether CQRS or microservices are justified. Do not use for pure frontend work or non-NestJS backends. When other skills also apply, reconcile ownership before mutation.

automattic Bundle

Use when editing or migrating Calypso Reader data-fetching code — `client/components/data/query-reader-*` components, `@automattic/data-stores` Reader hooks, or new Reader queries/mutations. Triggers on any work involving `api-core`, `api-queries`, `dispatchRequest`, `READER_*_REQUEST` actions, or Redux `isRequesting*` selectors in the Reader.

b0d9a Skill

Use Orca's computer-use CLI to inspect and operate local desktop app windows through accessibility trees, screenshots, and safe UI actions. Use for desktop app interaction: list apps/windows, get app state, read visible UI, click controls, type, press keys, scroll, drag, set values, or perform accessibility actions. Also use for browser windows, webviews, Orca app UI, or other desktop UI. Triggers include "computer use", "orca computer", "read Spotify", "read Slack", "control/click/read in a desktop app", and "get app state".

b0d9a Skill

Control a mobile (iOS) emulator / simulator stream from inside Orca using the `orca` CLI. Use for taps, gestures, typing, hardware buttons, camera injection, permissions, accessibility tree, and more — all while seeing the live view in Orca's emulator pane. Prefer this over raw `npx serve-sim` or direct simctl when running agents inside Orca (the orca surface handles device scoping, helper lifecycle, and worktree context). Complements the orca-cli skill for terminals, worktrees, and the built-in browser.

b0d9a Skill

Control an Android emulator / device from inside Orca using the `orca` CLI. Use for listing/booting AVDs, taps, swipes, typing, hardware buttons (incl. Back and Recents), rotation, app install/launch, runtime permissions, the accessibility tree, and logcat — driving a real adb-connected device or emulator. Cross-platform (Windows, Linux, macOS).
