Generate architecture procedurally in Three.js and film it assembling — a small geometry vocabulary that builds pagodas, castles, domes and spires from parameters instead of mesh files, hip roofs with flying eaves driven by a single profile function, and a clipping-plane build animation where everything below a rising line is finished work and scaffolding stands above it. Use for construction studies, architectural title sequences, procedural landmarks, or any hero object that should build itself rather than fade in
Use when writing or debugging AActor and UActorComponent C++: constructor vs BeginPlay, PostInitializeComponents, EndPlay cleanup, SpawnActor/SpawnActorDeferred/FinishSpawning, CreateDefaultSubobject, NewObject + RegisterComponent, SetupAttachment/AttachToComponent, tick groups, UChildActorComponent, UINTERFACE, actor pooling. Also use when the user mentions 'BeginPlay', 'Tick', 'SpawnActor', 'CreateDefaultSubobject', 'attach a component', 'root component', 'lifecycle', 'PrimaryActorTick', 'FAttachmentTransformRules'. For collision and overlaps, see ue-physics-collision; for GameMode/Pawn/Controller, see ue-gameplay-framework; for replicated actors, see ue-networking-replication.
Use upbit CLI for Upbit REST API — spot orders, market data, withdrawals, deposits, travel rule, account management. 업비트 CLI로 시세 조회, 주문, 잔고 확인, 입출금을 처리합니다. Trigger this skill whenever the user wants to query prices, place/cancel orders, check balances, withdraw or deposit assets, or interact with the Upbit exchange API — in any language. 사용자가 업비트 시세·주문·잔고·입출금을 언급하면 반드시 이 스킬을 사용하세요.
Checks a GitHub, GitLab, or Perforce (p4) pull request (or merge request, or shelved changelist) for unresolved review comments, failing status checks, and incomplete PR descriptions. Waits for pending checks to complete, categorizes issues as actionable or informational, and optionally fixes and resolves them. Use when the user wants to check a PR/MR/CL, address review feedback, or prepare a change for submission.
Diagnose and mitigate GKE TPU or GPU nodes stuck in NotReady / NodeStatusUnknown ("Kubelet stopped posting node status") due to host kernel panics, hardware lockups, or disabled node auto-repair. Use when nodes stop heartbeating beyond the node auto-repair threshold and pods remain stuck in Terminating. Don't use for healthy nodes, pod-only application crashes, or routine GKE upgrades
Generate, preview, save, or validate Preline theme CSS using the bundled local generator in this skill. Use when the user asks to create a new Preline theme, match a brand color, translate a mood into a theme, generate light and dark theme CSS, preview theme output without writing files, or review and fix generated theme tokens. Do not use for generic non-Preline CSS work or arbitrary command execution.
Implements and debugs deep links in Capacitor apps - custom URL schemes, iOS Universal Links (apple-app-site-association, Associated Domains entitlement), Android App Links (assetlinks.json, autoVerify), and routing via @capacitor/app `appUrlOpen` + `App.getLaunchUrl()`. Covers the Capacitor 8.5+ UIScene change where AppDelegate `application(_:open:options:)` and `continue userActivity` stop being called and custom handling must move to SceneDelegate, plus cold vs warm launch testing. Use when links open Safari/Chrome instead of the app, `appUrlOpen` never fires, the launch URL is lost on cold start, or OAuth redirects do not return to the app. Do not use for the full UIScene migration (capacitor-uiscene-migration), push notification taps (capacitor-push-notifications), or social login plugin setup (capacitor-plugins).
This skill should be used when the user asks to "콘텐츠 정리", "아티클 요약", "PDF 학습", "영상 정리", "트윗 정리", "digest", "summarize", "정리해줘", or provides a YouTube URL, X/Twitter URL (x.com, twitter.com), webpage URL, or PDF file for analysis. Supports YouTube (transcript), X/Twitter (via fetch-tweet skill), webpage (full content via browser), and PDF (text + image per page). Generates Quiz-First learning with 9 questions across 3 difficulty levels
Use to write the hook — the opening that earns attention — for any social content: a caption's first line, a video's first three seconds, a carousel cover slide, a thread opener, a YouTube title, or an email subject. Run when the user says "write a hook," "hook for this," "opening line," "first three seconds," "cover slide," "make this scroll-stopping," or when good content keeps getting ignored. Reads brand-profile and voice first so hooks sound like the brand, not viral-bait templates. Hooks must be TRUE to the content that follows — this skill extracts the hook from the post's strongest element and never overpromises. For full captions use caption-writer; for full video scripts use the video skills. This writes the opening itself.
Use when the user asks for STRIDE threat modeling, DREAD risk scoring, data-flow-diagram threat analysis, or a quick secret scan — or when a security request needs routing to the right specialist skill (pen-testing, incident response, cloud posture, red team, AI security, threat hunting, secure code review). This skill owns threat modeling; everything else routes to a sibling.
Authenticate to the Sumsub API with an App Token + secret key (HMAC-SHA256 request signing). TRIGGER when the user asks to "call / sign / authenticate Sumsub API requests", debugs `401 Unauthorized` / signature errors against `api.sumsub.com`, or needs a working request example with `X-App-Token` / `X-App-Access-Sig` / `X-App-Access-Ts` headers. SKIP only when a more specific skill in this repo (questionnaire/level/workflow/POA-preset/generic) already covers the user's actual task—those skills sign requests the same way and only need this one for auth deep dives.
When the user wants to plan, implement, or optimize affiliate marketing strategy. Also use when the user mentions "affiliate marketing," "affiliate program strategy," "CPS model," "affiliate recruitment," "commission structure," "affiliate partners," "affiliate network," "affiliate tracking," "affiliate commission," or "partner marketing." For affiliate page, use affiliate-page-generator
Create, integrate, or audit production-ready rigged 3D characters and monsters with a main model, skeleton, animation library, sockets, collision contracts, separate character equipment, optimized runtime files, catalog media, and an interactive moveset inspector. Use when generating or importing FBX/GLB game actors; defining character-versus-monster asset requirements; separating swords, shields, helmets, armor, or stowed gear; adding idle, walk, run, attack, hit, dodge, block, cast, or death clips; wiring an asset into gameplay; or adding action and equipment controls plus deterministic tests to a game asset catalog
USE FOR RAG/LLM grounding. Returns pre-extracted web content (text, tables, code) optimized for LLMs. GET + POST. Adjust max_tokens/count based on complexity. Supports Goggles, local/POI. For AI answers use answers. Recommended for anyone building AI/agentic applications.
Profitable niche discovery for Amazon sellers. Identifies underserved markets with high demand but low competition. Analyzes market gaps, emerging segments, and untapped opportunities across categories. Use when the user asks about finding niches, profitable markets, underserved segments, market gaps, blue ocean opportunities, niche research, or what markets to enter on Amazon.
When the user wants to optimize content for SEO—word count, H2 keywords, keyword density, multimedia, tables, lists. Also use when the user mentions "content length," "word count," "keyword stuffing," "H2 keywords," "keyword density," "tables," "bullet points," or "content structure." For keywords, use keyword-research
Generates custom design system rules for the user's codebase. Use when the user says “create design system rules,” “generate rules for my project,” “set up design rules,” “customize design system guidelines,” or wants to establish project-specific conventions for Figma-to-code workflows. Requires Figma MCP server connection.
Use this skill when creating a new Phaser 4 game instance or configuring GameConfig options. Covers renderer selection, canvas setup, scaling, pixel art, FPS settings, boot sequence, and all config sub-objects. Triggers on: new Phaser.Game, GameConfig, game setup, renderer, pixel art, FPS.
Work with the @upstash/box TypeScript/JavaScript SDK for sandboxed cloud containers with AI agents, shell, filesystem, git, cron schedules, snapshots, and a headless browser. Use when building with Upstash Box, creating a sandbox or isolated environment to run untrusted or agent-generated code, running AI coding agents in containers, giving an agent a cloud dev environment with a shell and repository, browser automation from a box, scheduling recurring jobs inside a box, saving and restoring snapshots, or orchestrating parallel boxes.
Use when defining or implementing Go interfaces, designing abstractions, creating mockable boundaries for testing, or composing types through embedding. Also use when deciding whether to accept an interface or return a concrete type, or using type assertions or type switches, even if the user doesn't explicitly mention interfaces. Does not cover generics-based polymorphism (see go-generics).
Build, redesign, and critique clean, presentation-grade slide decks (.pptx) for any audience — research/lab meetings, work status updates, conference talks, stakeholder readouts, thesis defenses, teaching, webinars. Use whenever the user wants to make, create, redo, clean up, improve, or review slides / a deck / a presentation — e.g. “make slides for my project”, “build a deck from this paper/code/doc”, “turn these results into slides”, “redesign this pptx”, “my slides are too dense”, “review my deck and tell me what's weak”, “make a slide about X”, “help me present this work”. Works with or without a template (matches theirs, else designs a clean one) and with or without source material (mines provided code/docs/figures, else web-researches and fact-checks), in any language (e.g. English or Chinese). Interviews first, then runs an actor–critic loop until an independent critic consents. Trigger even without the words “skill”, “deck”, or “pptx”
Gets, filters, streams, and saves logs and crash reports from Capacitor apps on iOS Simulator, iPhone, Android emulator and devices. Explains where Capacitor output goes (iOS bridge and mirrored JS console lines are stdout-only, so missing from Console.app and `log stream`; Android tags `Capacitor` and `Capacitor/Console`). Covers `xcrun simctl spawn booted log stream --predicate`, `simctl launch --console-pty`, `xcrun devicectl device process launch --console`, `log collect --device-udid`, Console.app, devicectl `systemCrashLogs`, `adb logcat --pid`, `-b crash`, Android Studio `package:mine`, tombstones, ANRs, `adb bugreport`. Use for "how do I see logs", "console.log not showing on device", "no logs in Console.app", "get the crash log", "logcat too noisy". Do not use for diagnosing the bug once logs are in hand (debugging-capacitor), production crash SDKs (capacitor-native-observability), MCP log tooling (capacitor-mcp), or profiling (capacitor-performance)
Interactive onboarding that learns your communication style, audiences, and data sources to configure personalized status briefings. Paste in examples of updates you already write, answer a few questions, and roundup calibrates itself to your workflow
Use when executing implementation plans with independent tasks in the current session or facing 3+ independent issues that can be investigated without shared state or dependencies - dispatches fresh subagent for each task with code review between tasks, enabling fast iteration with quality gates
Catch-all fallback for any Sumsub API task that does NOT match a more specific skill (e.g. `create-sumsub-level`, `sumsub-create-questionnaire`, `sumsub-api-auth`). TRIGGER when the user wants to call, inspect, or debug a Sumsub API endpoint not otherwise covered—fetching applicants, listing levels, reviewing AML hits, exporting data, generating SDK tokens, anything against `api.sumsub.com`. The procedure—locate the right endpoint in the OpenAPI schema, read its request/response shape, build the payload, sign with App Token, and validate. SKIP whenever a narrower Sumsub skill already covers the request.
Add restrained mouse-driven orbit and parallax depth to a Three.js hero by damping one pointer target and splitting it across camera translation, look-at, and small object rotations. Use for passive cinematic 3D heroes, pointer-responsive scenes, organic model parallax, and interactive depth where OrbitControls would feel like a product viewer.
Agentforce Builder metadata path for Builder-managed topics/actions, Prompt Builder templates, GenAiFunction/GenAiPlugin, Models API, and custom Lightning types. TRIGGER when: user maintains or configures Builder metadata agents, creates topics/actions, works with Prompt Builder templates, or touches .genAiFunction, .genAiPlugin, or .genAiPromptTemplate metadata XML files. DO NOT TRIGGER when: Agent Script DSL .agent files (use sf-ai-agentscript), agent testing (use sf-ai-agentforce-testing), or persona design (use sf-ai-agentforce-persona).
Find the questions people ask about a market, how ChatGPT answers them, and which sites get cited in the answers. Use when the user asks what people ask AI about their niche, wants prompt ideas, or wants to know where their brand is missing before choosing prompts to track. Research only; it never saves tracking or starts answer collection.
Perform actions in Linear (read, create, update, search issues, projects, comments, teams, cycles, labels, etc.) by writing and running small Node scripts against the official @linear/sdk TypeScript SDK with a personal API key. Use this when the user wants to do Linear work from the terminal without the Linear MCP server, or asks to list/open/create/update/close Linear issues, leave comments, or query teams, projects, users, or workflow states
Guides the usage of Gemini API on Google Cloud Vertex AI with the Gen AI SDK. Use when the user asks about using Gemini in an enterprise environment or explicitly mentions Vertex AI. Covers SDK usage (Python, JS/TS, Go, Java, C#), capabilities like Live API, tools, multimedia generation, caching, and batch prediction.
Install, compose, theme, and animate Bklit UI charts (the @bklit shadcn registry) in a React / Next.js app. Use when the user wants a chart, graph, or data visualization: line, area, bar, live/streaming line, composed, scatter, candlestick/OHLC, pie, ring/donut, radar, gauge, heatmap, funnel, sankey, sunburst, or choropleth/world map; a sparkline or tiny inline chart (LineSparkline, AreaSparkline, BarSparkline, useSparklineHover) for tables, KPI cards, or dense dashboards; a dashboard, analytics page, KPI or stat card; chart tooltips, crosshairs, legends, markers, reference bands, projections, trend lines, axes, or grids; or when code imports from components/charts/* or mentions @bklit/* or bklit.com. For styling vocabulary (patterns, squircle/rounded/3D bars, fades, loading looks, matching the app theme) also use bklit-ui-design. For moving from Recharts, shadcn ChartContainer, or TanStack Charts to Bklit, use bklit-ui-migrate.
Use when writing or reviewing documentation for Go packages, types, functions, or methods. Also use proactively when creating new exported types, functions, or packages, even if the user doesn't explicitly ask for documentation. Does not cover code comments for non-exported symbols (see go-style-core).
React 19 performance patterns and composition architecture for Vite + Cloudflare projects. 50+ rules ranked by impact — eliminating waterfalls, bundle optimisation, re-render prevention, composition over boolean props, server/client boundaries, and React 19 APIs. Use when writing, reviewing, or refactoring React components. Triggers: 'react patterns', 'react review', 'react performance', 'optimise components', 'react best practices', 'composition patterns', 'why is it slow', 'reduce re-renders', 'fix waterfall'.
Test for WCAG 2.2 AA compliance with axe-core + Playwright, keyboard navigation audits, screen reader testing, ARIA pattern validation, and legal compliance mapping (ADA, EAA, Section 508). Automated tools catch 30-40% of issues — this skill covers automated and manual testing together. Use when: "accessibility," "a11y," "WCAG," "screen reader," "axe," "keyboard navigation," "ARIA," "ADA compliance." Not for: cookie-consent/GDPR compliance — use compliance-testing; pixel-diff visual regression — use visual-testing. Related: playwright-automation, compliance-testing, visual-testing, ci-cd-integration
Guides the agent through upgrading a Capacitor app project to a newer major version. Supports upgrades from Capacitor 4 through 8, including multi-version jumps. Performs all upgrade steps manually — does not use the interactive `npx cap migrate` command. Do not use for plugin library upgrade or non-Capacitor mobile frameworks.
Audit and review application UI for IDS compliance, accessibility, usability, and cognitive load. Covers component usage validation, WCAG accessibility checks, cognitive load assessment, and UX quality evaluation. Use when asked to review UI, check accessibility, assess usability, audit IDS compliance, or when the user says "review this page", "check a11y", or "is this accessible?"
Create, extract, and apply portable visual design systems via visual-style.md files. Use when: (1) Creating a visual-style.md design system from scratch, (2) Extracting a visual style from a website URL, video, or PDF brand guide, (3) Applying a visual style to HeyGen videos, HTML slides, Figma, or paper.design, (4) Browsing the gallery of pre-built visual styles (Swiss, Saul Bass, Game Boy, etc.), (5) User mentions "visual style", "design system", "brand style", or "style guide", (6) Styling a HeyGen video with a consistent design language.
Use when one Python service must send each agent's, tenant's, team's, or request's spans to its correct Arize space and project using application metadata. Covers dynamic OpenTelemetry routing for custom agent builders and multi-tenant applications, including register_with_routing, set_routing_context, multi-space tracing, and custom span routing.
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.
