Use when creating animations that feel warm, welcoming, and make users feel comfortable engaging.
React 18.3.1 and React 19 dependency compatibility matrix.
Provides the complete, verified grep scan command library for auditing React codebases before a React 18.3.1 or React 19 upgrade. Use this skill whenever running a migration audit - for both the react18-auditor and react19-auditor agents. Contains every grep pattern needed to find deprecated APIs, removed APIs, unsafe lifecycle methods, batching vulnerabilities, test file issues, dependency conflicts, and React 19 specific removals. Always use this skill when writing audit scan commands - do not rely on memory for grep syntax, especially for the multi-line async setState patterns which require context flags.
Provides exact patterns for diagnosing and fixing automatic batching regressions in React 18 class components. Use this skill whenever a class component has multiple setState calls in an async method, inside setTimeout, inside a Promise .then() or .catch(), or in a native event handler. Use it before writing any flushSync call - the decision tree here prevents unnecessary flushSync overuse. Also use this skill when fixing test failures caused by intermediate state assertions that break after React 18 upgrade.
All-in-one Module Federation skill. Use when the user asks anything about MF — concepts, configuration, runtime API, shared dependencies, type errors, runtime error code troubleshooting, slow builds, Bridge integration, or adding MF to an existing project.
Wires the Navigation component from @cognite/dune-industrial-components/navigation into a Dune app. Use when adding a navigation header, top nav bar, sticky header, nav items, active page, nav links, navigation component, theme toggle, or dark mode support to a Dune app.
Guides consumption and understanding of Fusion backend services, APIs, and patterns for frontend/client developers, integrators, and architects. Shows reference implementations, explains architectural decisions, and clarifies contracts. USE FOR: understanding Fusion backend APIs, learning implementation patterns, exploring reference code, choosing the right integration point, and understanding authorization/validation/async patterns. DO NOT USE FOR: modifying backend services, creating new endpoints, database changes, or backend-specific development (use fusion-services-develop or backend service repo instead).
Master React, Vue, and Svelte component patterns including CSS-in-JS, composition strategies, and reusable component architecture. Use when building UI component libraries, designing component APIs, or implementing frontend design systems.
A designer-turned-developer who crafts stunning UI/UX even without design mockups. Code may be a bit messy, but the visual output is always fire.
Use when creating HTML email templates with React components - welcome emails, password resets, notifications, order confirmations, newsletters, or transactional emails.
Create a library-grade Vue composable that accepts maybe-reactive inputs (MaybeRef / MaybeRefOrGetter) so callers can pass a plain value, ref, or getter. Normalize inputs with toValue()/toRef() inside reactive effects (watch/watchEffect) to keep behavior predictable and reactive. Use this skill when user asks for creating adaptable or reusable composables.
Conduct comprehensive web performance audits. Measure page speed, identify bottlenecks, and recommend optimizations to improve user experience and SEO.
