Run a full Dune app platform review against a React/TypeScript CDF codebase, following the cognitedata/dune-app-reviews scoring criteria. Produces three artifacts: review-files.md (per-file inventory), review-packages.md (dependency audit), and review-report.md (scored report with must/should/nice-fix items). Use when the user asks for a Dune app review, pre-submit review, approval review, app certification review, code quality audit, CDF platform review, or "run dune-review" on a codebase before submission.
Expert frontend developer specializing in modern web technologies, React/Vue/Angular frameworks, UI implementation, and performance optimization
Production-ready animation patterns for React / Next.js — button, modal, toast, stagger, page transitions, exit animations, scroll, and layout — built on motion-foundations tokens and springs.
MUST activate when the user wants to build, create, or generate a React application, React app, web application, single-page application (SPA), or frontend application — even if no project files exist yet. MUST also activate when the project contains a uiBundles/*/src/ directory or sfdx-project.json and the prompt says create, build, construct, or generate a new app, site, or page from scratch — even if the prompt also describes visual styling. MUST also activate when the task spans more than one ui-bundle skill. Use this skill when building a complete app end-to-end. This is the orchestrator that coordinates scaffolding, features, data access, frontend UI, integrations, and deployment in the correct dependency order. Without it, phases execute out of order and the app breaks. Do NOT use for Lightning Experience apps with custom objects (use generating-lightning-app). Do NOT use for single-concern edits to an existing page (use building-ui-bundle-frontend).
Best practices for Remotion - Video creation in React. Use when creating programmatic videos with Remotion, adding animations or transitions, working with audio/captions, rendering compositions, embedding 3D content, building charts, or using Mapbox maps in video.
Frontend development skill for React, Next.js, TypeScript, and Tailwind CSS applications. Use when building React components, optimizing Next.js performance, analyzing bundle sizes, scaffolding frontend projects, implementing accessibility, or reviewing frontend code quality.
React Three Fiber animation - useFrame, useAnimations, spring physics, keyframes. Use when animating objects, playing GLTF animations, creating procedural motion, or implementing physics-based movement.
Entity management and state handling in GPUI. Use when working with entities, managing component state, coordinating between components, handling async operations with state updates, or implementing reactive patterns. Entities provide safe concurrent access to application state.
Minimal, unopinionated state management library for React with simple hook-based API, no providers, and minimal boilerplate for global state without Redux complexity.
