Web & Frontend

pproenca Skill

Drive a real Expo / React Native iOS app from an AI agent using expo98 — the efficient, safe boot→inspect→act→evidence loop. Use when an agent must test, inspect, or capture evidence from a running Expo app instead of hand-rolling xcrun/simctl/CDP/Metro calls.

prebid Bundle

Generic iOS/Swift reference material — Swift idioms, architecture notes, accessibility and HIG checklists, and size-class handling. Background reading only; not specific to this SDK. For ObjC → Swift migration, use the migration-patterns skill instead.

jonisavo 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.

jrajasekera Bundle

Convert documents between formats using Pandoc. Use when the user asks to convert files between formats like markdown, docx, html, pdf, latex, epub, rtf, csv, xlsx, or pptx. Triggers on requests like "convert this to Word", "export as PDF", "turn this markdown into HTML", or "convert the CSV to a table".

jsirish Bundle

Migrate legacy SilverStripe blocks (sheadawson/silverstripe-blocks or dynamic/dynamic-blocks) to SilverStripe Elemental during an SS3→SS4 (or later) upgrade. Covers the migration BuildTask, the block-class → element-class mapping catalog, the BlockArea → ElementalArea relation mapping, the legacy-template → element-template duplication pattern (preserving HTML/CSS verbatim), and the area-suffix template convention for area-specific rendering (`Element_RelationName.ss`). Use when: - A project still has populated `SiteTree_Blocks` / `Block` tables - Element templates render but the HTML doesn't match the legacy site - You need different rendering of the same Element class in different page areas (sidebar vs main content vs home-content) - You're starting a new SS3→SS4 upgrade and want a proven workflow

juice-shop Bundle

Instructions for writing automated tests (frontend, server, API, Cypress E2E) that keep code coverage high for new functionality and close existing coverage gaps found in lcov.info files.

juncoding Skill

Retrofit Redis-backed cache handling into an existing project scaffolded with nextjs-fullstack-starter. Use when the user wants to add Redis, share Next.js cache across processes / deploys, speed up frequent reads, or any 'add caching to this project' request. Adds ioredis, a docker-compose redis service, wires Next.js's experimental cacheHandler to use Redis, adds a typed cache helper at src/server/lib/cache.ts, and REDIS_URL env. Refuses to run on projects that don't have the scaffolded structure.

juncoding Bundle

Scaffold a brand-new fullstack back-office app on pure Next.js (App Router) — Server Components for reads, Server Actions for writes, services in src/server/modules/. Use this whenever the user wants to start a new internal tool, admin dashboard, back-office app, line-of-business system, lightweight ERP, or CRUD app on Next.js without a separate API service — even if they don't name the stack. Walks the user through an interactive Q&A (project name, location, database, auth, cache, MCP, deployment target), then generates the canonical folder structure, dependencies, sample Server Action, sample service, Prisma schema starter, .env.example, and CLAUDE.md. Always trigger when the user wants a Next.js fullstack starter without tRPC, when they describe building a back office with Server Components, or when they say 'one Next.js app does everything'.

juncoding Bundle

Reference patterns for ongoing development on a Next.js fullstack project scaffolded with nextjs-fullstack-starter — Server Components for reads, Server Actions for writes, services in src/server/modules/. Use this whenever adding a new module, writing a new page or Server Action, deciding between Server Action vs route handler vs MCP tool, wiring permissions, structuring services, handling errors, caching with cacheTag / updateTag, or making any architectural decision in a project that was bootstrapped with this plugin. Triggers on phrases like 'add a new module', 'create a Server Action', 'where should this logic go', 'follow project conventions', 'how do I invalidate the cache', 'should this be a page or an action', or any 'how do I do X in this project' question.

juncoding Bundle

Reference patterns for ongoing development on a Next.js + tRPC + Prisma project scaffolded with nextjs-trpc-prisma-starter. Use this whenever adding a new module, writing a new tRPC procedure, deciding between tRPC vs route handler vs MCP tool, wiring permissions, structuring services, handling errors, or making any architectural decision in a project that was bootstrapped with this plugin. Triggers on phrases like 'add a new module', 'create a tRPC procedure', 'where should this logic go', 'follow project conventions', or any 'how do I do X in this project' question.

juncoding Bundle

Scaffold a brand-new lightweight internal management system on Next.js + tRPC + Prisma in SPA / client-component mode. Use this whenever the user wants to start a new internal tool, admin dashboard, back-office app, CRUD app, management system, or operational SaaS starter — even if they don't name the stack. Walks the user through an interactive Q&A (project name, location, database, auth, cache, MCP, deployment target), then generates the canonical folder structure, dependencies, sample tRPC router, sample service, Prisma schema starter, .env.example, and CLAUDE.md.

junjie-xyz Bundle

Clarify requirements through batched interactive HTML questionnaires. Use when the user explicitly invokes @Ask or @ask, selects the Ask Skill, or explicitly says "ask me questions." Do not trigger for ordinary clarification requests without one of these explicit signals. Supports localized text, rich HTML, SVG, flowchart, and mockup options, with direct submission in Codex or copy-only standalone output.

jykim Bundle

Convert markdown documents to HTML format for website publishing with dark theme styling, image conversion (Excalidraw to PNG/SVG), and proper frontmatter handling

kaustavr19 Bundle

Perform a thorough, professional UI/UX audit of any existing website or web product. Runs a CORE six-framework audit by default — Nielsen's 10 Heuristics, WCAG 2.2 Accessibility, Gestalt, UX Writing & Microcopy, Mobile/Responsive, and Performance & Core Web Vitals — and offers optional DEEP LENSES on request: Classic Usability Extended (Shneiderman, Gerhardt-Powals, Bastien & Scapin), Behavioural Laws (Hick's, Fitts's, Miller's, Jakob's, Peak-end), Trust & Persuasion (Fogg, Cialdini), and Interaction Design Principles (Norman, Tognazzini). Produces a markdown report with severity tiers, RAG status, fix recommendations, and effort estimates. Use whenever the user wants to audit, review, or critique a website, app, or web product's UI/UX — including "roast my site", "review this product", "what's wrong with this UI", "give me a UX review". Also trigger when the user shares a URL or screenshots for design feedback, or asks for a persuasion / behavioural-psychology / cognitive-load / dark-pattern review.

keez97 Skill

Expert frontend architecture review and design for modern web apps. Review existing apps against rendering strategy, state management, Core Web Vitals, bundle efficiency, and project structure. Design new apps with concrete ADRs, performance budgets, and migration paths. Catch bundle bloat, state leaks, hydration mismatches, and performance gaps before they hit production. Stop shipping unnecessary JavaScript.

kennethkhoocy Bundle

Convert Markdown (.md) files to a polished PDF with ALL images preserved and scaled to the page. Use whenever the user asks to "save this markdown as a PDF", "convert README.md to pdf", "export the .md as a pdf", "turn these notes/docs into a PDF", or wants a PDF deliverable of any GitHub-flavored Markdown document (README, design doc, report, notes) — especially when it contains images or diagrams (remote or local), tables, code blocks, or a linked table of contents. Pipeline: pandoc (GFM → standalone HTML with embedded resources) → headless Chrome print-to-pdf with a GitHub-like print stylesheet → pypdf verification that every referenced image is embedded. Do NOT use for .tex → PDF (use a LaTeX toolchain) or for .docx work (use word-docx / tex2docx).

kennethkhoocy Bundle

Download the actual PDF binary from bot-gated sites (taxpolicycenter.org, urban.org, SSRN-hosted mirrors, think-tank/publisher sites) via the Wayback Machine id_ URL form. Use when: (1) curl/WebFetch of a .pdf URL returns HTML instead of a PDF even with a browser User-Agent, (2) pypdf fails with "invalid pdf header: b'<!DOC'" or "EOF marker not found" on a freshly downloaded file, (3) Firecrawl can parse the PDF to markdown but you need the original file on disk (e.g., filing a reference copy).

kohaku-lab Skill

Compose videos and frame sequences with HyperFrame's HTML format: project layout, frame authoring, rendering.

santhoshtr Bundle

Build web UIs using Wikimedia Codex design tokens (CSS custom properties) for consistent styling. Supports custom components, themed applications, design-to-code conversion, MediaWiki integration, and standalone web apps with automatic light/dark mode.

serenakeyitan Bundle

Render study flashcards into an interactive HTML deck.

serverpod Skill

Serve static files and directories with caching and cache busting in Relic. Use when serving assets, images, CSS, JS, favicons, or configuring HTTP cache control headers.

shopify Skill

Interact with iOS simulator or Android emulator/device using snapshot-based coordinates. Uses accessibility tree snapshots for precise element targeting, with screenshot verification as fallback. Use when navigating the app on a simulator/emulator.

shopify Skill

Upgrade the React Native fixture app to a new version. Covers JS deps, Android (Gradle, Kotlin, SDK), iOS (Podfile, pbxproj), Metro config, and third-party libraries.

siesdart Bundle

Review a project's folder architecture and produce evidence-backed structural candidates in a visual HTML report.

siesdart Bundle

Apply React View–Logic separation when creating, modifying, or refactoring components with multiple state variables, event handlers, Effects, async flows, or UI policy. Extract cohesive custom Hooks around meaningful use cases while preserving state ownership, minimal contracts, and readable JSX; do not split merely to reduce Hook count or create generic lifecycle wrappers.

siesdart Bundle

Review a frontend application's rendered component or widget tree from the top-level entry point downward. Use when assessing whether UI nodes are cohesive, appropriately split, easy to change and test, and connected by clear technology-neutral contracts such as inputs, outputs, events, slots, bindings, or shared context.

skandm Bundle

Render a trip's settled plan into a self-contained, shareable HTML itinerary page. Trigger when the user asks to export, share, print, or "make a page for" a trip ("export the Cape May trip", "make something I can send my mom", "give me a printable itinerary"), or as an offer right after itinerary-builder flips a trip to status ready. Reads trips/<trip>/trip.md as the only content source, scrubs traveler-profile rationale (health, dietary, mobility reasons never leave trip files), writes trips/<trip>/itinerary.html from the bundled template, and optionally publishes it as a private claude.ai Artifact link when that tool is available. The export is derived output — trip.md stays the source of truth and the page is regenerated, never hand-maintained.

specialone0007 Bundle

Read-only, repository-agnostic feature readiness audit for finding bugs, launch blockers, regressions, UI/UX flow errors, accessibility issues, auth/data risks, missing critical tests/docs, and production readiness gaps in a named feature, route, URL, workflow, product surface, or PR, or across the whole repository when no scope is named. Use when the user explicitly asks for a feature/product-surface audit, scan, launch-readiness check, production-readiness review, or bug-risk report. If the primary ask is security, test coverage, docs drift, repo organization, feature ideas, or PR communication, use security-audit, test-gap-audit, docs-sync-audit, repo-health-audit, feature-brainstorm, or pr-branch-summary instead.

adelabdelgawad Bundle

Next.js Template Skill

adelabdelgawad Bundle

Create Next.js data table pages with SSR initial load, SWR caching, and server-response-based UI updates. Use when asked to create a new data table page, entity management page, CRUD table, or admin list view. Generates page.tsx (SSR), table components, columns, context, actions, and API routes following a proven architecture with centralized reusable data-table component.

aditya-ariosity Bundle

Specify, map, document, validate, and package an approved UX/UI design or prototype into build-ready behavior, component, responsive, state, accessibility, analytics, QA, and acceptance contracts. Trigger on "prepare developer handoff", "hand off to engineering", "create implementation specs", "spec this design", "document component behavior", or "write acceptance criteria". Do not use while the product model is still being redesigned or invent backend contracts.

aditya-ariosity Bundle

Redesign a dashboard, KPI view, operational console, or analytical workspace around real decisions and data meaning. Trigger on "redesign this dashboard", "redesign this report", "clean up this analytics view", "improve these KPIs", or "fix this reporting view". Use ux-ui-audit for diagnosis without redesign and design-system-review for library-wide component issues. Do not invent metrics or thresholds.

agentera Bundle

Streaming outputs, runtime streams, and ReAct-style tool loops.

agenthouse-org Bundle

Design and verify frontend changes through explicit design principles, browser-driven acceptance tests, and screenshot evidence. Use when building or changing a web UI where visual quality, responsive behavior, accessibility, and proof of the delivered result matter.
