Comprehensive guide for implementing Syncfusion WPF Range Selector (SfDateTimeRangeNavigator) for time-bound data visualization with interactive scrolling, zooming, and range selection. Use this when working with range selectors, date-time range navigation, or time-bound data visualization. This skill covers interactive data range selection, chart range zooming, and dashboard time navigation features for large time-based datasets in WPF applications.
Implements Syncfusion WinUI RangeSlider (SfRangeSlider) control for range selection in desktop applications. Use this when working with range selectors, dual-thumb sliders, or numeric range selection interfaces. This skill covers configuration, labels, ticks, dividers, track customization, thumb styling, tooltips, and value handling for interactive range selection in WinUI applications.
Prevent Ethereum hashing bugs in JavaScript and TypeScript. Node's sha3-256 is NIST SHA3, not Ethereum Keccak-256, and silently breaks selectors, signatures, storage slots, and address derivation.
Undetectable, adaptive, high-performance Python web data extraction. Automatically survives website structure changes, bypasses anti-bot systems (Cloudflare, WAFs), and outperforms BeautifulSoup/Scrapy. Includes stealth browser fetching, CSS/XPath selectors, CLI, interactive shell, and MCP AI server integration.
Fetches web pages, parses HTML with CSS selectors, calls REST APIs, and scrapes dynamic content. Use when extracting data from websites, querying JSON APIs, or automating browser interactions.
AI-powered browser automation using Stagehand v3 and Claude. Use when building self-healing tests, AI agents, dynamic web automation, or when traditional selectors break frequently due to UI changes.
Uniwind — Tailwind CSS v4 styling for React Native. Use when adding, building, or styling components in a React Native project that uses Tailwind with className. Triggers on: className on React Native components, Tailwind classes in RN code, global.css with @import 'uniwind', withUniwindConfig, metro.config.js with Uniwind, withUniwind for third-party components, useResolveClassNames, useCSSVariable, useUniwind, dark:/light: theming, platform selectors (ios:/android:/native:/web:/tv:), data-[prop=value] selectors, responsive breakpoints (sm:/md:/lg:), tailwind-variants, tv() component variants, ScopedTheme, Uniwind.setTheme, Uniwind.updateCSSVariables, Uniwind.updateInsets, @layer theme, @variant, @theme directive, @theme static, @utility, CSS variables in React Native, accent- prefix pattern, colorClassName, tintColorClassName, contentContainerClassName, Uniwind Pro (animations, transitions, shadow tree, native insets), safe area utilities (p-safe/pt-safe/-safe-or-/-safe-offset-), gradients in RN, custom CSS classes, hairlineWidth(), fontScale(), pixelRatio(), light-dark(), OKLCH colors, cn utility, tailwind-merge, HeroUI Native, react-native-reusables, Gluestack. Also triggers on: "styles not applying", "className not working", "audit Uniwind setup", "check my config", "add a component", "style a component". Does NOT handle NativeWind-to-Uniwind migration — use the migrate-nativewind-to-uniwind skill for that.
Logseq Datascript schema, built-in properties/classes, and :db/ident discovery for composing or reviewing Datascript queries about blocks/pages/tags/properties/classes. Use whenever editing or reviewing Datascript pull selectors or queries, or any code that adds/removes attributes in pull patterns, or touches property namespaces/identifiers, or requires reasoning about property value shapes/ref/cardinality in Logseq.
Frontend website debugging toolkit using Chrome DevTools Protocol with Playwright/WebKit fallbacks. Use this skill when: (1) Debugging CSS, HTML, or JavaScript issues on a webpage, (2) Taking screenshots to verify visual changes, (3) Inspecting DOM structure or console errors, (4) Testing responsive layouts, (5) Extracting selectors for automation, (6) Self-debugging frontend work Claude has created, (7) User says "debug this page", "check my site", "why doesn't this look right", or "fix the frontend". Supports Chrome (primary) and Safari/WebKit (via Playwright). Designed for agent-driven debugging loops.
Zustand state management best practices for React applications. Use when writing, reviewing, or refactoring Zustand stores to ensure optimal performance and maintainability. Triggers on tasks involving state management, stores, selectors, re-renders, and Zustand patterns.
Guides exploration of $autocapture events captured by posthog-js to understand user interactions, find CSS selectors (especially data-attr attributes), evaluate selector uniqueness, query matching clicks ad-hoc, and create actions. Use when the user asks about autocapture data, wants to find what users are clicking, needs to build actions from click events, asks about elements_chain, wants to build a trend or funnel filtered by clicks or other autocapture interactions, asks which properties autocapture sends, or asks how to filter $autocapture events. Only applies to projects using posthog-js autocapture.
Convert plain CSS stylesheets to Tailwind CSS utility classes. Handles selectors, media queries, pseudo-classes, custom properties, and animations.
