Design and build game UI/UX — HUDs, menus, and overlays — that survive every screen: anchor-based responsive layout, resolution/aspect scaling and safe areas, keyboard/gamepad focus navigation, a screen/menu state stack, and event-driven (not polled) HUD updates. Engine-neutral patterns that pair with the detected engine's UI skill. Use when the user mentions HUD, health bar, main menu, pause menu, settings screen, UI layout, anchors, UI scaling, aspect ratio, safe area, controller/keyboard menu navigation, or wiring UI to game state.
Next.js 16+ and Turbopack guidance — incremental Rust bundling, file-system caching, faster dev startup and HMR, Turbopack vs webpack tradeoffs, and the middleware.ts to proxy.ts filename change. Use when developing or debugging Next.js 16+ apps, diagnosing slow dev startup or hot reload, choosing between bundlers, or reviewing middleware/proxy file naming.
Design multi-cloud architectures using a decision framework to select and integrate services across AWS, Azure, GCP, and OCI. Use when building multi-cloud systems, avoiding vendor lock-in, or leveraging best-of-breed services from multiple providers.
SDFormat/SDF model and world authoring, validation, and simulator handoff. Use for `.sdf` files, SDFormat XML, models, worlds, links, joints, poses, frames, inertials, visual/collision geometry, mesh URIs, sensors, lights, physics, plugins, includes, Gazebo, static SDF review, or simulator-specific metadata. Do not use for signed-distance-field geometry. Open and visually review existing SDF files in CAD Viewer.
Implement saga patterns for distributed transactions and cross-aggregate workflows. Use this skill when implementing distributed transactions across microservices where 2PC is unavailable, designing compensating actions for failed order workflows that span inventory, payment, and shipping services, building event-driven saga coordinators for travel booking systems that must roll back hotel, flight, and car rental reservations atomically, or debugging stuck saga states in production where compensation steps never complete.

Use for text-to-Lottie, SVG/logo/type animation, loaders/icons, state feedback, UI microinteractions, lower thirds, diagrams, data/stat/chart animations, product promos, scene/camera motion, visual effects, scene edits, slots/controls, and Skottie debugging.
Create, modify, debug, and deploy Apify Actors, and write their input and output schemas. Use when building an Actor from scratch, changing or troubleshooting Actor code, generating or updating .actor schema files, or pushing an Actor to the Apify platform. To wrap an existing non-Actor project, use apify-actorization instead
Run the full Spring Boot verification loop — Maven or Gradle build, SpotBugs, PMD, and Checkstyle static analysis, unit and Testcontainers integration tests with JaCoCo coverage, OWASP dependency and secret scans, and diff review — producing a pass/fail readiness report. Use when preparing a Spring Boot pull request, validating coverage thresholds, or running pre-deploy verification.

Usage skill for the official Kling AI CLI: image/video generation, reusable Element subjects, and motion control. The CLI interacts with Kling through an MCP service: call text_to_image / image_to_image / text_to_video / image_to_video / omni_ref_video / motion_control (models and parameter specifications are declared dynamically by who_am_i), poll with query_tasks after receiving generationId, then extract works[].url and show it to the user when complete. Commands have no aliases. Triggers: 可灵, Kling, text-to-image, image-to-image with a reference image, text-to-video, image-to-video, Omni, omni, MCP, generationId, generation_id, polling, inspiration points, text_to_image, image_to_image, text_to_video, image_to_video, omni_ref_video, all-purpose reference, keyframes, motion_control, motion_library_list, Element, element_create, element_list, element_get, element_update, element_delete, feedback, query_tasks, who_am_i, file_upload, image generation, video generation, Kling command, .credentials, domestic site, international site, global, international version, region, install
URDF robot description authoring and validation. Use when creating, editing, inspecting, validating, or debugging `.urdf` files, robot links, joints, limits, inertials, visual/collision geometry, mesh references, frame conventions, or robot-description artifacts. Use the SRDF skill for MoveIt2 semantic groups and IK/path-planning semantics; use the CAD skill for STEP/STL/3MF/DXF/GLB outputs. Open and visually review existing URDF files in CAD Viewer.
Extract a comprehensive design system (DESIGN.md) directly from frontend source code — React, Vue, Svelte, Angular, plain HTML/CSS, or any web framework. Analyzes component files, stylesheets, Tailwind configs, theme definitions, and design tokens to produce a rich, Stitch-compatible design system document. Use this skill whenever the user wants to reverse-engineer a design system from an existing codebase, audit the visual language of a project, extract design tokens from source files, or understand the styling patterns in a frontend repo — even if they just say "what does this app look like?" or "pull out the design from this code."
Cross-platform UI/UX design reviewer grounded in Apple's Human Interface Guidelines (123 pages pulled from developer.apple.com, including 57 component pages) plus a design-craft lens for distinctive, non-templated work. Use it to audit, review, critique, or improve any mobile app (iOS, Flutter, React Native) or desktop app (macOS, Tauri, Electron) design: design review, UI audit, HIG compliance, accessibility audit, dark mode, Liquid Glass or glassmorphism, navigation structure, iPhone Duo or foldable layouts, Apple Pay buttons and marks, widgets and Live Activities, onboarding, forms, app icons, generative AI UX, App Review rejections over design or branding, or requests like "make this look less generic". Also use whenever the user shares screenshots, mockups, wireframes, Figma exports, or UI code and wants feedback, even if they only say "review my design" or "is this good UI", or asks to audit a codebase or pull request. Works for SwiftUI, UIKit, AppKit, Flutter, React Native, Tauri, and Electron.

Configure secure, high-performance connectivity between on-premises infrastructure and cloud platforms using VPN and dedicated connections. Use when building hybrid cloud architectures, connecting data centers to cloud, or implementing secure cross-premises networking.
Guides the usage of Gemini Interactions API on Gemini Enterprise Agent Platform. Use when the user wants to use the stateful, server-managed Interactions API for multi-turn conversations, background execution, streaming, structured output, and function calling on the Agent Platform.
MoveIt2 SRDF authoring, validation, and planning-semantics workflow. Use when creating, editing, inspecting, or validating `.srdf` files, MoveIt planning groups, virtual joints, passive joints, end effectors, group states, disabled collisions, URDF-paired planning semantics, or SRDF handoff for live review. Use the URDF skill for robot structure and the SDF skill for simulator descriptions. Open and visually review existing SRDF files in CAD Viewer.
Create and update pitch decks, one-pagers, investor memos, accelerator applications, financial models, and fundraising materials. Use when the user needs investor-facing documents, projections, use-of-funds tables, milestone plans, or materials that must stay internally consistent across multiple fundraising assets.
Token holder chip analysis—deep analysis of holder structure, including chip distribution, entry cost, whale/dev/KOL behavior, risk wallets (rat traders, bundlers, snipers), related wallets, smart money signals, and an AI rating based purely on token structure. Use when the user asks about holder analysis, 筹码分析, 持仓分析, chip structure, who is holding, or whether a token is safe to buy based on its holder composition.
Capture architectural decisions as numbered ADR markdown files in docs/adr/ with context, alternatives considered, consequences, and an index README. Use when the user says 'record this decision' or 'ADR this', chooses between frameworks or databases, discusses trade-offs, or asks why the codebase is shaped this way.
Deploy, configure, and integrate Sandbox Agent — a universal API for orchestrating AI coding agents (Claude Code, Codex, OpenCode, Amp) in sandboxed environments. Use when setting up the sandbox-agent server locally or in cloud sandboxes (E2B, Daytona, Docker), creating and managing agent sessions via SDK or API, streaming agent events and handling human-in-the-loop interactions, building chat UIs for coding agents, or understanding the universal schema for agent responses.
Search live flight fares for a route and date across Agoda, Trip.com, and Traveloka — one-way or round-trip, any cabin, with airline, times, stops, duration, and a direct booking link. Use when the user wants flight prices, plane or air tickets, cheap flights or airfare between two cities, comparing airlines for travel dates, or planning the flying leg of a trip.
Gemini-native Nano Banana image generation and editing across Nano Banana, Nano Banana 2, and Nano Banana Pro. Use when you need text-to-image, image-to-image edits, repeated local references, batch generation, dry-run request inspection, or a custom Gemini-compatible base URL such as a self-hosted gateway
Builds, reviews, and measures UI motion, including springs, gestures, scroll effects, curve fitting from recordings, and sparse interface sound. Use when asked to "add animation", "match this easing", "reverse engineer this motion", "add a click sound", or find animation opportunities.
Persistent file-based planning for multi-step AI-agent work. Keeps task_plan.md, findings.md, and progress.md on disk; lifecycle hooks inject selected project planning context. Automatic recovery reads project planning files only. Explicit session-catchup.py --metadata reads same-project local agent session records and emits aggregate counts only; --replay may emit bounded nonce-framed excerpts. Optional gated mode can request continuation only when the host supports it and never runs commands declared in Markdown. The skill has no network upload path. Use for research or work needing 5+ tool calls.
Compare live hotel room rates across Booking.com, Agoda, Traveloka, and OpenTravel for specific dates — which OTA is cheapest for the same property, per-room prices, and free-cancellation terms. Use when comparing hotel prices, checking room rates for a named hotel, asking which site is cheaper, or finding the best rate for given check-in/check-out dates.
Decision framework for parsing structured text (quizzes, forms, invoices, receipts, tables) with a hybrid regex-first pipeline: regex extraction handles 95%+ cheaply, a confidence scorer flags low-confidence items, and an LLM validator fixes only the edge cases. Use when choosing between regex and LLM for text extraction, building a low-cost document parser, or optimizing extraction cost and accuracy.
Review DXF and STEP/STP uploads for SendCutSend.com orders using its ordering guide, catalog, and specs. Use only for SendCutSend.com preflight reports covering upload readiness, selected material/SKU/thickness/service availability, and service-specific checks for laser cutting, CNC routing, bending, tapping, countersinking, hardware insertion, and finishing
Use this skill when the user asks for: the price of any asset, ticker, order book, candles, OHLCV, funding rate, open interest, OI change scanner, market screener (top movers, high-volume, newly listed), mark price, index price, recent trades, instrument list, stock tokens, metals prices (gold, XAU, XAG), commodities (oil, OIL), forex rates (EUR/USD, EURUSDT), bond instruments, non-crypto assets, or any technical indicator query (RSI, MACD, EMA, Bollinger Bands, KDJ, SuperTrend, AHR999, BTC rainbow, and 70+ more). All commands are read-only and do NOT require API credentials. Do NOT use for account balance/positions (okx-cex-portfolio), placing/cancelling orders (okx-cex-trade), or bots (okx-cex-bot). Do NOT use when the user wants to TRADE a directional view as an event contract — that is okx-cex-trade. Merely ASKING which way an asset's price is moving is a market-data question and belongs here.
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.
