Comprehensive skill for Anime.js v4, a fast and flexible JavaScript animation library. Use this skill when implementing web animations, creating timelines, working with SVG animations, scroll-based animations, draggable elements, staggered effects, or any JavaScript-based animation on the web. Triggers on: "anime.js", "animejs", "animate elements", "CSS animation with JS", "timeline animation", "stagger animation", "SVG morphing", "motion path", "scroll animation", "draggable", "spring animation", "keyframe animation".
Apply Spatie's Laravel and PHP coding standards for tasks involving creating, editing, reviewing, refactoring, or formatting Laravel/PHP code or Blade templates. Use for controllers, Eloquent models, routes, config, validation, migrations, tests, and related files to align with Laravel conventions and PSR-12.
Use when wiring player input in Unreal C++ with Enhanced Input—input actions, mapping contexts, triggers, modifiers, binding handlers, and runtime key rebinding. Also use when the user mentions “Enhanced Input,” “UInputAction,” “UInputMappingContext,” “AddMappingContext,” “BindAction,” “SetupPlayerInputComponent,” “ETriggerEvent,” “input trigger,” “input modifier,” “SwizzleAxis,” “dead zone,” “WASD,” “gamepad,” “key rebinding,” “UEnhancedInputUserSettings,” or “input mapping priority.” For UI input modes and CommonUI routing, see ue-ui-umg-slate; for PlayerController/Pawn possession, see ue-gameplay-framework
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.
Expert skill for writing FreeCAD Python scripts, macros, and automation. Use when asked to create FreeCAD models, parametric objects, Part/Mesh/Sketcher scripts, workbench tools, GUI dialogs with PySide, Coin3D scenegraph manipulation, or any FreeCAD Python API task. Covers FreeCAD scripting basics, geometry creation, FeaturePython objects, interface tools, and macro development.
Workflow and best practices for writing Apache Airflow DAGs. Use when creating a new DAG, write pipeline code, handling questions about DAG patterns and conventions or extending an existing DAG with a follow-up/downstream task. ANY request shaped like 'add a DAG named X', 'write a pipeline', 'add a task that runs after Y', or 'extend the DAG'. For testing and debugging DAGs, see the testing-dags skill.
Develop TypeScript/Three.js games in isolated workspaces, plan games and create, edit, upgrade, animate, and prepare production-ready game assets with Meowa. Use for Game Designer research and design documents, pixel or HD sprites, consistent variants, multi-view or Spine characters, UI sheets, image and frame edits, Pindou bead art, textures, terrain tilesets, maps, video, sound effects, music, spoken dialogue (TTS or voice clone), bundled Meowa CLI execution, or final game-project deliverable validation.
Build responsive, mobile-first layouts using fluid containers, flexible units, media queries, and touch-friendly design that works across all screen sizes. Use this skill when creating or modifying UI layouts, responsive grids, breakpoint styles, mobile navigation, or any interface that needs to adapt to different screen sizes. Apply when working with responsive CSS, media queries, viewport settings, flexbox/grid layouts, mobile-first styling, breakpoint definitions (mobile, tablet, desktop), touch target sizing, relative units (rem, em, %), image optimization for different screens, or testing layouts across multiple devices. Use for any task involving multi-device support, responsive design patterns, or adaptive layouts.
Put weather into a Three.js scene that reads as weather — rain anchored inside the frustum, a storm that is the rain leaned on rather than a second system, lightning on its own light with thunder scheduled by distance, snow that blows up into blizzards and keeps settling until the ground goes white, wet ground with puddles and splashes, and looping ambience that has no seam. Use for scene atmosphere, seasonal states, hero backdrops, or any world where clear/rain/storm/snow needs to be a control the viewer can turn
Use when hardening Go code at API boundaries — copying slices/maps, verifying interface compliance, using defer for cleanup, time.Time/time.Duration, or avoiding mutable globals. Also use when reviewing for robustness concerns like missing cleanup or unsafe crypto usage, even if the user doesn't mention "defensive programming." Does not cover error handling strategy (see go-error-handling).
Feature planning and implementation with 4 adaptive phases (Specify, Design, Tasks, Execute). Auto-sizes depth by complexity. Asks every product decision before the spec is approved, writes testable requirements in EARS notation, atomic tasks with a gate and a commit each, and one check per criterion with the test that proves it. Captures that come with the request bind, and each screen is judged against them. Ships deterministic Python scripts so the gates are enforced by code, not memory; the proofs run once at the end, and an independent Verifier (author != verifier) spends its time on mutations and judgement. Use when (1) planning features, (2) implementing with verification and atomic commits, (3) validating an implementation against a spec. Triggers on "specify feature", "discuss feature", "design", "tasks", "implement", "validate", "verify work", "UAT", "record decision", "pause work", "resume work". Do NOT use for pure architecture decomposition analysis or standalone technical design documents.
Use when working with MasterData v2 entities, schemas, or MasterDataClient in VTEX IO apps, or when anyone designing or implementing a solution must scrutinize whether Master Data is the correct storage. The skill prompts hard questions: native Catalog or other VTEX stores, OMS, or an external database may be better; do not default to MD because it is convenient. Covers JSON Schema, CRUD, triggers, search and scroll, schema lifecycle, purchase-path avoidance, single source of truth, and BFF handoffs. Use for justified custom persistence while avoiding the 60-schema limit.
Use when modelling designer-authored game data in C++ and loading it: data assets, data tables, curve tables, soft references and asset streaming. Also use when the user mentions 'UDataAsset', 'UPrimaryDataAsset', 'UDataTable', 'FTableRowBase', 'FindRow', 'FDataTableRowHandle', 'TSoftObjectPtr', 'TSoftClassPtr', 'FSoftObjectPath', 'UAssetManager', 'LoadPrimaryAsset', 'FStreamableManager', 'RequestAsyncLoad', 'asset bundles', 'PrimaryAssetTypesToScan', 'IAssetRegistry', 'CSV import', or 'hard vs soft reference'. For save games, see ue-serialization-savegames; for UPROPERTY basics, see ue-cpp-foundations; for level streaming, see ue-world-level-streaming.
App-level security audit and hardening for Capacitor apps. Use when the user wants a security review, OWASP MASVS check, or pentest fixes; runs the Capgo scanner (`npx @capgo/capgo-sec scan`, `capsec`, rule IDs like SEC001, NET003, CAP004); finds API keys or `.env` values in the web bundle; stores tokens in `@capacitor/preferences` or `localStorage`; needs Keychain/Keystore storage, certificate pinning, CSP, or root/jailbreak detection; or sees `server.cleartext`, `allowNavigation`, `webContentsDebuggingEnabled`, `NSAllowsArbitraryLoads`, `android:usesCleartextTraffic`, `android:allowBackup`, `net::ERR_CLEARTEXT_NOT_PERMITTED`, or ATS "requires the use of a secure connection" errors. Do not use for Xcode build-setting hardening (use capacitor-ios-security-hardening), deep link setup (capacitor-deep-linking), App Store review (capacitor-apple-review-preflight), CI design (capacitor-ci-cd), or live update setup (capgo-live-updates).
Guide users building apps, scripts, CI pipelines, or automations on top of the Cursor TypeScript SDK (`@cursor/sdk`). Use this skill whenever the user mentions integrating, installing, or writing code against the Cursor SDK; whenever they say `Agent.create`, `Agent.prompt`, `Agent.resume`, `agent.send`, `run.stream`, `CursorAgentError`, or `@cursor/sdk`; whenever they ask to run Cursor agents programmatically from a script, CI/CD pipeline, GitHub Action, backend service, or any other code that isn't the Cursor IDE itself; and whenever they want to pick between local and cloud runtime, configure MCP servers for an SDK agent, or handle streaming, cancellation, or errors from an SDK agent. Also trigger when a user is wiring Cursor into an automation, writing a bot that runs Cursor, or porting REST `/v1/agents` calls to the SDK, even if they don't explicitly name the package. Use this eagerly rather than answering from memory; the SDK surface evolves and this skill plus its references are the source of truth for the external package
You are a code refactoring expert specializing in clean code principles, SOLID design patterns, and modern software engineering best practices. Analyze and refactor the provided code to improve its quality, maintainability, and performance
Set up Shopify CLI authentication and Admin API access for a store. Install the CLI, authenticate, create a custom app, store the access token, and verify. Use whenever the user wants to connect to a Shopify store, set up Shopify API access, install Shopify CLI, or troubleshoot Shopify authentication or Admin API token issues.
Use when answering questions about, generating, refactoring, or troubleshooting wot-ui v2 code. Keywords: wot-ui, uni-app, Vue3, wd-, ConfigProvider, useToast, useDialog, Form, Popup, theme, llms-full. Suitable for component selection, API lookup, example page generation, theme customization, and troubleshooting common pitfalls.
Apply when working with GraphQL schema files in graphql/ or implementing resolvers in node/resolvers/ for VTEX IO apps. Covers schema.graphql definitions, @cacheControl and @auth directives, custom type definitions, and resolver registration in the Service class. Use for exposing data through GraphQL queries and mutations with proper cache control and authentication enforcement.
Build type-safe global state in React with Zustand. Supports TypeScript, persist middleware, devtools, slices pattern, and Next.js SSR with hydration handling. Prevents 6 documented errors. Use when setting up React state, migrating from Redux/Context, or troubleshooting hydration errors, TypeScript inference, infinite render loops, or persist race conditions
Open a paperthin iteration's casebook before re0-loop's first turn — seeded with real content the moment the folder exists, never an empty directory. User-invoked, paperthin-only: assumes the full skill package installed. Run when opening a new build cycle in this repo.
Manage Sumsub `clientWebhooks` (event subscriptions for applicantReviewed / applicantPending / kytTxn / etc.) — reads via `/resources/api/clientWebhooks`, writes via `/resources/api/agent/clientWebhooks`. **Sandbox only** — production webhooks must be created by a human directly in the Sumsub dashboard. TRIGGER when the user asks to "list / retrieve / show webhooks", "create / add / register a webhook", or "update / edit / change a webhook target / event list / secret / signature algorithm" against their sandbox tenant. SKIP for production webhook setup (refer the user to the dashboard), for unrelated webhook surfaces (Stripe / videoIdent / Fireblocks / NFC / partner-specific receive paths under `/resources/webhooks/...`), for testing one-off delivery (use the `inspectionCallbacks/testWebhook` endpoint directly), and for KYT-only webhook routing (that's managed in the Sumsub dashboard's KYT section). The public API does not expose delete or per-webhook delivery stats — for those, refer the user to the Sumsub dashboard UI.
Configure-Price-Quote (CPQ) vertical skill for the Customware SPA. Defines patterns, minimum standards, layout patterns, lifecycle indicators, product configurator patterns, business rule templates, and mapping rules for transforming a DOMAIN.md into a CPQ-shaped application. Targeted at SMB customers (5-50 employees) migrating from spreadsheets and email-based quoting workflows. The prototype must feel dramatically better than Excel without feeling enterprise-overcomplicated. Patterns are defaults, not mandates — adapt them when the actual workflow deviates. Trigger signals: quoting, pricing, product configuration, calculators, guided intake forms, assessment tools, estimate builders, proposal workflows, eligibility checkers, any "fill in fields → calculate → produce a deliverable" pattern.
Use when creating Go packages, organizing imports, managing dependencies, or deciding how to structure Go code into packages. Also use when starting a new Go project or splitting a growing codebase into packages, even if the user doesn't explicitly ask about package organization. Does not cover naming individual identifiers (see go-naming).
Load this skill when a user asks how to run Pulumi programmatically, embed Pulumi in an application, orchestrate multiple stacks in code, build a self-service infrastructure portal, replace pulumi CLI shell scripts with code, or use the Pulumi Automation API (LocalWorkspace, createOrSelectStack, inline programs). Also load for questions about multi-stack sequencing, parallel deployments, or passing outputs between stacks via code.
End-to-end recipe for adding Sumsub KYC to a website or web app via the Sumsub WebSDK. TRIGGER when the user asks to "integrate / embed / add Sumsub", "show the KYC widget", "add WebSDK", "verify users with Sumsub on the frontend", supplies an existing levelName they want to plug into a page, or asks how to wire up access tokens / lifecycle events / webhooks for Sumsub verification in an arbitrary project. Covers the whole loop — level setup, server-side access-token signing, snsWebSdk init (vanilla canonical, React recipe), client lifecycle events, token refresh, source-of-truth via webhooks + applicant GET, sandbox testing, go-live checklist. SKIP for building the level/questionnaire/POA-preset payload itself (use the sibling skills), or for backend-only API calls with no frontend (use `sumsub-api-generic`)
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
Makes Capacitor apps work with VoiceOver, TalkBack, Dynamic Type / Android font scale, Switch Control, hardware keyboards, Reduce Motion and Increase Contrast. Covers Capacitor-specific gaps - WKWebView not following iOS Dynamic Type, Android WebView text zoom breaking layouts, zoomEnabled/user-scalable, SPA route changes not announced, native views under the WebView (maps, camera preview) being unreachable, @capacitor/screen-reader (isEnabled, speak, stateChange) and @capacitor/text-zoom (getPreferred, set) - plus testing with Accessibility Inspector, simctl content_size, adb font_scale, TalkBack and axe-core, mapped to WCAG 2.2. Do not use for Ionic component styling (use ionic-design), notch/home-indicator layout (use safe-area-handling), keyboard overlap bugs (use capacitor-keyboard), automated test framework setup (use capacitor-testing), or App Store metadata (use capacitor-app-store).
Create, modify, debug, or review Windows Forms applications only when the request contains a concrete Windows Forms marker. USE FOR: WinForms, Windows Forms, System.Windows.Forms, WinForms Form or UserControl designer files (*.Designer.cs or *.Designer.vb), Visual Studio WinForms Designer, TableLayoutPanel, BindingSource, DataGridView, Control.InvokeAsync, component-tray ownership, or custom control serialization. DO NOT USE FOR: WPF or WPF XAML, including Window.InputBindings, KeyBinding, commands, or DataContext; .NET MAUI; Avalonia; or any request where none of the listed Windows Forms markers is present.
Chinese documentation typesetting reference — conventions for Chinese-English spacing, full-width and half-width punctuation, term retention, link formatting, and Chinese copy layout. Invoke only when the user explicitly specifies /chinese-documentation; do not trigger automatically based on context.
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
Build type-safe validated forms using React Hook Form v7 and Zod v4. Single schema works on client and server with full TypeScript inference via z.infer. Use when building forms, multi-step wizards, or fixing uncontrolled warnings, resolver errors, useFieldArray issues, performance problems with large forms.
Comprehensive software architecture skill for designing scalable, maintainable systems using ReactJS, NextJS, NodeJS, Express, React Native, Swift, Kotlin, Flutter, Postgres, GraphQL, Go, Python. Includes architecture diagram generation, system design patterns, tech stack decision frameworks, and dependency analysis. Use when designing system architecture, making technical decisions, creating architecture diagrams, evaluating trade-offs, or defining integration patterns
Use when the user wants to create, audit, or optimize sitemap.xml. Also use when the user mentions "sitemap," "sitemap.xml," "sitemap index," "lastmod," "changefreq," "priority," "URL discovery," "URL discovery for search engines," "single source of truth," "URL config," "unify sitemap IndexNow," or "reduce duplicate maintenance." For IndexNow, use indexnow.
Upgrade Prisma Next in your extension. Bump every `@prisma-next/*` dependency to the requested target (or npm `latest`), follow the per-transition upgrade instructions for the extension SPI (middleware lifecycle, codec / migration-tools / framework-components changes, seed-migration on-disk shape), verify exact pins with `prisma-next-check-pins`, run the extension's own typecheck and tests, and commit each minor step separately. Use when the user asks to “upgrade Prisma Next” in an extension package or update an extension's `@prisma-next/*` dependencies to a new minor
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.
Scaffold a full-stack Cloudflare app from the vite-flare-starter template — React 19 + Hono + D1+Drizzle + better-auth + Tailwind v4+shadcn/ui + TanStack Query + R2 + Workers AI. Run setup.sh to clone, configure, and deploy. Use whenever the user wants a batteries-included Cloudflare full-stack app, vite-flare-starter scaffold, or a React + Cloudflare app with auth + database + Workers AI ready to go
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.
