Build investment systems in the style of AQR Capital Management, the quantitative investment firm pioneering factor investing. Emphasizes academic rigor, transparent methodology, and systematic factor exposure. Use when building factor models, conducting asset pricing research, or designing systematic portfolios.
Build UIs using IBM's Carbon Design System. Use when the user requests Carbon-styled interfaces, IBM-style dashboards, enterprise UIs following Carbon conventions, or explicitly mentions Carbon, IBM design, or @carbon/react. Covers component usage, design tokens (color, typography, spacing, motion), theming (White, Gray 10, Gray 90, Gray 100), grid layout, and accessibility. Supports both artifact/HTML output (CDN-based) and full React project output (@carbon/react). Triggers include "Carbon", "IBM design system", "enterprise dashboard", "@carbon/react", "carbon components", or requests for IBM-style professional interfaces.
Extract a complete design system from an existing website or screenshot into a DESIGN.md file. Analyses colours, typography, component styles, spacing, and atmosphere through browser automation and HTML inspection. Produces a semantic design system document optimised for consistent page generation. Triggers: 'extract design system', 'design system', 'create DESIGN.md', 'analyse the design', 'what design does this site use', 'extract styles from', 'reverse engineer the design'.
Implements and debugs browser Web Neural Network API integrations in JavaScript or TypeScript web apps. Use when adding navigator.ml checks, MLContext creation, MLGraphBuilder flows, device selection, tensor dispatch and readback, or explicit fallback paths to ONNX Runtime Web or other local runtimes. Don't use for model training, server-side ML inference, or cloud AI APIs.
Guides implementation of the Syncfusion WinForms AutoLabel control for automatic label positioning with form controls. Use when users want to add labels that automatically reposition when controls move, create form layouts with paired label-control units, implement complex form designs with FlowLayout, or ensure labels stay synchronized with their associated controls. Covers labeling controls, positioning, spacing, size settings, theming, and events.
Fetch any URL as clean markdown. ALWAYS use this skill instead of the WebFetch tool when you need to read a URL's content — it has a 5-layer fallback (Jina Reader, defuddle.md, markdown.new, OpenCLI, raw HTML) that produces better results and handles JS-rendered pages (Twitter/X, SPAs), login-required platforms (zhihu, reddit, weibo, xiaohongshu), and complex web pages that WebFetch cannot parse. Invoke whenever the user provides a URL and wants to read, extract, summarize, analyze, or convert its content to markdown. Keywords: 'fetch page', 'read URL', 'grab content from', 'summarize article', 'extract text from webpage', '抓取网页', '读链接', '网页转 markdown'. NOT for: web search without URL, file downloads, screenshots, form filling, or accessibility checks.
Surgically updates a specific section of .marrow.md without re-running the full extraction. Accepts a new value, color, image, or description and patches only the relevant section — leaving everything else intact. Use this skill when the user wants to update one part of the extracted soul, change the brand accent color, update spacing rules, replace a typeface, refine the brand personality, or extract color from a new reference image. Triggers on: /marrow-update, or prompts like "update the accent color to X", "change the brand color", "update spacing in marrow", "the font changed to X", "update marrow with this new color", "patch marrow", "update just the accent", "marrow-update accent #FF6B6B", "update the palette from this image". Requires .marrow.md to exist. If not found, instructs user to run /marrow first.
This skill should be used when the user asks to "create a new React project", "setup a react app", "new react frontend", "scaffold a react spa", "initialize a react frontend", or "start a new react app". Scaffolds a React 19 + Vite + TypeScript + Tailwind CSS v4 + shadcn/ui + Redux Toolkit SPA with auth and routing.
Review football data code and visualisations for correctness. Use after building a chart, data pipeline, or analysis. Dispatches specialised reviewers for data correctness, chart conventions, visual inspection, and interactive edge cases.
Analyze the current workspace codebase and produce a single-file interactive C4 architecture diagram as HTML (L1 System Context → L2 Containers → L3 Components), with drill-down, breadcrumb, side panel, and light theme. Use when the user asks for C4 diagrams, interactive architecture HTML, system context/container/component views, or 可交互 C4 架构图. 分析当前项目代码结构，生成交互式 C4 架构图（单文件 HTML）：系统上下文、容器、组件三级下钻、面包屑、侧栏详情、浅色主题。触发词：C4 架构图、交互式架构、系统上下文、容器图、组件图、架构可视化、可下钻、architecture diagram、interactive C4。
Root-cause-driven solution decision framework for the hardest problems across any domain. This is the nuclear option — it consumes significant tokens through exhaustive multi-branch root cause analysis, MECE solution enumeration, and domain-adaptive external validation. Use ONLY for genuinely difficult problems: recurring failures that resist repeated fix attempts, complex systemic issues with no clear solution path, decisions where multiple approaches exist and the wrong choice has high cost, problems with multiple interacting causes spanning components or teams. Trigger when: the user says 'what's the best way to fix X', 'why does this keep happening', 'how should we approach this', 'find the root cause', 'what are my options for fixing X', 'analyze this problem systematically', 'evaluate our options for X', 'what's the right approach and why', or expresses frustration that previous solutions didn't stick. Do NOT use for: problems where the answer is already obvious or requires no analysis, straightforward issues with clear solutions, or routine investigation. If the problem can be solved in 5 minutes of investigation, this skill is overkill.
Comprehensive UI design skill covering fundamentals, patterns, and anti-patterns. Layout, typography, color, spacing, accessibility, motion, and component design. Use when building any web interface, reviewing design quality, or creating distinctive UIs.
