Troubleshoot: AnimatePresence exit, list performance, Tailwind conflicts, Next.js "use client", layout in scaled containers.
Build, define, and import React code components into Webflow via DevLink. Use when creating Webflow code components, configuring declareComponent definitions, working with prop types, styling within Shadow DOM, bundling with Webpack, or troubleshooting DevLink imports.
Universal coding standards, best practices, and patterns for TypeScript, JavaScript, React, and Node.js development.
Guides proper usage of the key prop in React lists. Use this skill when rendering lists, mapping arrays to components, or troubleshooting list-related state bugs.
Security-first PR review checklist for this repo. Use when reviewing diffs/PRs, especially changes involving auth, networking, sensitive data, or dependency/lockfile updates. Focus on secret/PII leakage risk, supply-chain risk (npm + node_modules inspection), cross-platform architecture (extension/mobile/desktop/web), and React performance (hooks + re-render hotspots). Avoid UI style nitpicks. PR Review.
Casper Studios internal design system for generating consistent, production-grade SaaS UI. Use this skill whenever generating UI code for internal tools, client apps, dashboards, POCs, prototypes, or any visual interface — even quick mockups or artifacts. Apply it any time the output is a React component, page, or layout. If the user mentions "our design system", "Casper style", "match our look", or asks you to build any kind of app or interface, use this skill. Also trigger when restyling or theming existing UI to match Casper's visual language. This skill takes priority over generic frontend-design guidance.
Write React components with minimal state, proper memoization, and type-safe patterns. Use when creating components, managing state, or optimizing renders.
Sentry JavaScript frontend bug pattern review based on real production errors. Use when reviewing React/TypeScript frontend code for common bug patterns. Trigger keywords: "javascript bug review", "frontend errors", "react error patterns", "sentry frontend bugs".
Zustand 5.x state management with slices, middleware, Immer, useShallow, and persistence patterns for React applications. Use when building state management with Zustand.
Review React/TypeScript code for bugs, security vulnerabilities, performance issues, accessibility gaps, and CLAUDE.md workflow compliance.
