Generate production-ready, accessible, token-driven component code for ANY framework (React+Tailwind, Next.js, SwiftUI, Vue, Svelte, Angular, Solid, Web Components/Lit, React Native, Flutter, Jetpack Compose, vanilla CSS, or CSS-in-JS). Use when the user wants working UI code for a component or screen in a specific stack
Compile a complete academic or senior professional curriculum vitae from notes, publication lists, and appointment history—with correct section order, honest bibliographic detail, and readable long-list hierarchy (not a one-page job resume). Use when the user asks for a CV, curriculum vitae, academic vita, faculty application CV, or multi-page career record. Create cvs with AI-native design and the highest aesthetic standards, powered by the K2F format and engine. Purpose-built for AI agents, K2F lets them focus on semantic content and design intent while automatically handling layout, typography, and formatting complexity.
Macro liquidity monitoring and risk early-warning system. By tracking 4 core indicators (Fed Net Liquidity, SOFR Overnight Financing Rate, MOVE Treasury Volatility Index, Yen Carry Trade Signals), it provides real-time assessment of liquidity conditions in the global financial system, outputting liquidity ratings and risk response recommendations. When users mention topics such as liquidity, Fed balance sheet reduction (QT), TGA account, reverse repo ON RRP, SOFR rate, MOVE index, Treasury volatility, yen carry trade, USDJPY and interest rate differentials, impact of QT on markets, whether money is tight, liquidity inflection points, tightening financial conditions, etc., this skill should be used. Even if users ask broadly "how is liquidity right now" or "is the Fed draining or injecting liquidity," this skill should be triggered to provide a structured analytical framework.
Use when installing or tuning the PreToolUse security hook that warns before Claude writes command injection, XSS, SQL injection, unsafe deserialization, eval or GitHub Actions injection. Warns once per file and rule; ENABLE_SECURITY_REMINDER=0 turns it off
Full Sentry SDK setup for React. Use when asked to "add Sentry to React", "install @sentry/react", or configure error monitoring, tracing, session replay, profiling, or logging for React applications. Supports React 16+, React Router v5-v7, TanStack Router, Redux, Vite, and webpack.
Add b-roll motion graphics to a talking-head video. Transcribes the recording with word timings, decides line by line when the speaker is shown, when a graphic is laid over them and when a full-frame graphic covers them, draws each graphic from what is actually said (numbers, comparisons, steps, key words) in JavaScript on a canvas, and renders the finished MP4 with the original sound, plus the b-roll alone with alpha for an editor. Use when someone has a recording of a person talking to camera (a talking head, a spoken explainer, a course lesson, an ad read, a podcast clip) and wants it more engaging to watch, wants b-roll, or wants motion graphics added to it
Patterns for using Testcontainers in .NET integration tests to spin up real dependencies like databases and message queues. Use when writing integration tests that require real databases, testing with message brokers like RabbitMQ or Kafka, or isolating test dependencies with Docker containers.
Run or troubleshoot Wrangler CLI commands in projects that have a wrangler.jsonc, wrangler.json, or wrangler.toml file, including local development, previews, deployment, and resource management. For new projects and projects without a Wrangler configuration file, use the cf CLI instead.
Applies this repository's skill-authoring standard as a procedure. Use for any change to, or judgment about, a file under skills/** — a SKILL.md, a reference, a persona prompt, a bundled script's instructions: creating a skill, editing one, reviewing a skill change, or acting on review feedback (human or bot) about one. Not for src/, tests/, or scripts/ code.
Analyzes git diffs or staged changes and generates narrative commit messages that explain WHY a change was made, not just what changed — following Conventional Commits format. Use when asked to “write a commit message”, “generate a commit”, “describe my changes”, “what should I commit this as”, “commit this”, “summarize my diff”, or “help me commit”. Works with git diff output, staged files, or plain descriptions of changes.
Real-time quotes, static reference, and valuation indices for stocks listed in HK / US / A-share / Singapore via Longbridge Securities. Returns last price, change, volume, turnover, market cap, industry, PE/PB, turnover-rate, and other indicators. Triggers: "现在多少钱", "股价", "涨跌幅", "成交量", "市值", "市盈率", "PE", "PB", "换手率", "行业", "現在多少", "股價", "成交量", "市值", "市盈率", "stock price", "current price", "quote", "market cap", "PE ratio", "valuation", "NVDA price", "AAPL quote", "茅台市值", "腾讯股价", "700.HK", "600519.SH".
Process multimedia files with FFmpeg (video/audio encoding, conversion, streaming, filtering, hardware acceleration) and ImageMagick (image manipulation, format conversion, batch processing, effects, composition). Use when converting media formats, encoding videos with specific codecs (H.264, H.265, VP9), resizing/cropping images, extracting audio from video, applying filters and effects, optimizing file sizes, creating streaming manifests (HLS/DASH), generating thumbnails, batch processing images, creating composite images, or implementing media processing pipelines. Supports 100+ formats, hardware acceleration (NVENC, QSV), and complex filtergraphs.
Explain, draft, or validate Obsidian Flavored Markdown syntax: properties, wikilinks, embeds, callouts, tags, comments, highlights, block references, math, and Mermaid. Use when the user explicitly requests Obsidian note formatting or syntax help, not for general Markdown or broad vault operations.
Check whether an SDK version supports a RevenueCat feature, whether an SDK upgrade is required, why an SDK-gated feature is not working, or how much of a project's recent subscriber base is on incompatible SDK versions. Use for questions about RevenueCat SDK compatibility, feature gates, minimum SDK versions, SDK adoption, upgrade impact, and rollout risk.
Systematic review response workflow from comment analysis to professional rebuttal writing. Use when the user asks to "write rebuttal", "respond to reviewers", "draft review response", or "analyze review comments". Improves paper acceptance rates.
SAP Analytics Cloud (SAC) automated testing skill for designing capability-gated browser discovery and deterministic Playwright test suites for SAC stories, dashboards, reports, planning workflows, comments, permissions, visual regression, and reusable QA automation. This skill should be used when building SAC end-to-end tests, onboarding SAC dashboards into Playwright, creating dashboard profiles or scenario YAML, using Microsoft Edge/CDP, Chrome DevTools MCP, Vercel Labs agent-browser, or manual discovery for SAC components, testing SAC optimized stories, configuring SAC auth storage state, managing visual/data baselines, testing comments, planning writeback, data actions, multi actions, role-based views, restricted Windows/company environments, or creating SAC failure triage artifacts.
Guided multi-page redesign of an existing website through a four-phase pipeline — extract (crawl and capture the current site), direct (set a visual direction), prototype (generate redesigned HTML), and migrate (emit a deployable static site). Tracks progress incrementally per page in stardust/state.json so redesigns are resumable. Delegates the per-page design craft (typography, spacing, color, layout, motion) to the impeccable skill. Use when the user wants to redesign, revamp, modernize, or restyle an existing site they can point to by URL, run the extract/direct/prototype/migrate flow, or resume a multi-page redesign or migration. Also routes the same-design migration flow (replica) and the donor-design flow (reskin). Not for designing a brand-new site from scratch or one-off single-component edits.
This skill provides comprehensive guidance for implementing advanced SwiftUI animations, transitions, matched geometry effects, and Metal shader integration. Use when building animations, view transitions, hero animations, or GPU-accelerated effects in SwiftUI apps for iOS and macOS.
Expert website copywriting for SaaS and B2B companies. Use when writing homepage copy, feature pages, about pages, pricing pages, comparison pages, product tours, integration pages, use case pages, demo/contact pages, or navigation microcopy. Use for website messaging hierarchy, value proposition development, and page-level conversion optimization.
Run an independent code review using the OpenAI Codex CLI in headless mode. Gets a second opinion from a different model family (the current Codex models) on recent changes, a PR, a commit, or the whole app — covering bugs, regressions, security, data consistency, UX/state bugs, performance risks, and testing gaps. Saves a severity-prioritised report to .jez/reviews/. Triggers: 'codex review', 'review with codex', 'independent code review', 'what does codex think', 'get codex to review'.
New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
