Development
Expose ZenStack V3 data as automatic CRUD web APIs ("Query as a Service") and consume them. Use when adding REST/RPC endpoints with a server adapter (Express, Fastify, Next.js, Nuxt, SvelteKit, Hono, Elysia, TanStack Start), wiring per-request access control via getClient/$setAuth, generating an OpenAPI spec, or calling the API from a client (fetch-client, TanStack Query hooks).
Manage database schema migrations in ZenStack V3. Use when creating/applying migrations (zen migrate dev/deploy/reset/status/resolve), prototyping with zen db push, introspecting an existing database with zen db pull, seeding, handling unsupported features (views) with --create-only, or wiring migrations into a deployment pipeline.
Expert patterns for game economies, including currency management (multi-currency, wallet systems), shop systems (buy/sell prices, stock limits), dynamic pricing (supply/demand), loot tables (weighted drops, rarity tiers), and economic balance (inflation control, currency sinks). Use for RPGs, trading games, or resource management systems. Trigger keywords: EconomyManager, currency, shop_item, loot_table, dynamic_pricing, buy_sell_spread, currency_sink, inflation, item_rarity
Expert blueprint for scene loading, transitions, async (background) loading, instance management, and caching. Covers fade transitions, loading screens, dynamic spawning, and scene persistence. Use when implementing level changes OR dynamic content loading. Keywords scene, loading, transition, async, ResourceLoader, change_scene, preload, PackedScene, fade
TypeScript type safety for Inertia Rails (React, Vue, Svelte): shared props, flash, and errors via InertiaConfig module augmentation in globals.d.ts. Use when setting up TypeScript types, configuring shared props typing, fixing TS2344 or TS2339 errors in Inertia components, or adding new shared data.
Use Rozenite for Agents through CLI-driven `rozenite agent` commands to inspect React Native DevTools data and Rozenite plugins on a live app target. Trigger this skill for shell-based debugging and live session work. For Node.js or TypeScript scripts, wrappers, automations, or other programmatic SDK usage, use `rozenite-agent-sdk` instead.
Update Remotion’s ffmpeg-next Git revision to a published rust-ffmpeg commit, refresh Cargo.lock, rebuild all supported compositor binaries, validate the monorepo, and open a draft pull request. Use for the final step of the rust-ffmpeg binary update chain.
Zig compiler skill for systems programming. Use when compiling Zig programs, selecting optimization modes, using zig cc as a C compiler, reading Zig error messages, or understanding Zig's compilation model. Activates on queries about zig build-exe, zig build-lib, optimize modes, ReleaseSafe, ReleaseFast, ReleaseSmall, zig cc, zig ast-check, or Zig compilation errors.
Use when you need to apply Java secure coding best practices — including validating untrusted inputs, defending against injection attacks with parameterized queries, minimizing attack surface via least privilege, applying strong cryptographic algorithms, handling exceptions securely without exposing sensitive data, managing secrets at runtime, avoiding unsafe deserialization, and encoding output to prevent XSS. This should trigger for requests such as Review Java code for secure coding; Find input validation risks in Java code; Review Java code for injection vulnerabilities; Improve secure error handling in Java services; Harden Java code against common security flaws. Part of Plinth Toolkit
Build, fix, audit, and migrate Drift persistence in Dart CLI, server-side, and non-Flutter desktop apps. Use when adding SQLite with package:drift/native.dart, configuring PostgreSQL with drift_postgres and package:postgres, writing type-safe tables, queries, writes, streams, and migrations, resolving build_runner or drift_dev failures, or validating Dart database code with code generation, analysis, tests, and migration checks
Generates Enonic XP content type XML schema definitions from natural-language descriptions. Covers structured content modeling including input types, form layout, option sets, item sets, mixins, x-data, and content-type inheritance. Use when creating, scaffolding, or generating Enonic XP content type definitions, adding fields or sets to existing content types, or querying Enonic XP input types and super-types. Do not use for non-Enonic content modeling, GraphQL queries, JavaScript/TypeScript controllers, or generic XML editing unrelated to Enonic schemas.
Implement API versioning strategies including URL versioning, header versioning, backward compatibility, deprecation strategies, and migration guides. Use when dealing with API versions, deprecating endpoints, or managing breaking changes
Expert-level automotive systems, connected vehicles, fleet management, telematics, ADAS, and automotive software. Use when the user mentions connected car, fleet, telematics, ADAS, or vehicle, or when the task involves Automotive Systems, Technologies, Standards and Protocols, or Fleet Management.
Create complete documentation sites for projects. Use when asked to: "create docs", "add documentation", "setup docs site", "generate docs", "document my project", "write docs", "initialize documentation", "add a docs folder", "create a docs website". Generates Docus-based sites with search, dark mode, MCP server, and llms.txt integration.
Use when protecting Express or Node.js API endpoints with JWT Bearer token validation, scope-based access control, or DPoP binding. Integrates express-oauth2-jwt-bearer — use even if the user says "validate tokens in my Express API" or "protect my Node.js API endpoints".
Trigger Novu notification workflows to send messages across email, SMS, push, chat, and in-app channels. Supports single triggers, bulk triggers, broadcast to all subscribers, topic-based targeting, and cancellation. Use when sending transactional notifications, alerts, or any event-driven messages.
Composes, debugs, and optimizes Guillotine GraphQL queries for Enonic XP headless content delivery. Covers query construction, variable usage, filtering, aggregation, pagination, sorting, and TypeScript type generation from the auto-generated Guillotine schema. Use when writing or troubleshooting Guillotine queries, querying custom content types through GraphQL, or generating typed interfaces from Guillotine responses. Don't use for content type XML definitions, non-Enonic GraphQL APIs (Apollo, Hasura), server-side lib-content queries, or Guillotine deployment and CORS configuration.
Testing Inertia Rails responses with RSpec and Minitest: component assertions, prop matching, flash verification, deferred props, and partial reload helpers. Use when writing controller specs, request specs, or integration tests for Inertia pages. ALWAYS use matchers (render_component, have_props, have_flash), NOT direct access (inertia.component, inertia.props). CRITICAL: after POST/PATCH/DELETE with redirect, MUST call follow_redirect! before asserting flash or props — without it you're asserting against the 302, not the Inertia page. Setup: require 'inertia_rails/rspec'.
Responsive UI transformation patterns for Tailwind CSS applications. Use this skill when making interfaces responsive, refactoring layouts for multiple screen sizes, or reviewing responsive Tailwind code. Triggers on tasks involving breakpoint strategy, layout adaptation, responsive spacing, fluid typography, mobile navigation, touch interaction, responsive media, or data table responsiveness.
Three.js 3D graphics library — scene setup, geometry, materials, lighting, textures, animation, loaders, shaders, postprocessing, interaction. Use when building 3D web experiences, creating WebGL visualizations, working with GLTF models, implementing custom shaders, or adding interactive 3D elements to web applications.
Upgrade Datadog Browser SDK from v6 to v7. Use when encountering removed options like betaEncodeCookieOptions, allowFallbackToLocalStorage, trackBfcacheViews, usePciIntake, changed APIs like forwardErrorsToLogs, startDurationVital, stopDurationVital, or when a project references datadoghq-browser-agent.com CDN with /v6/ paths.
Integrate Gemini API with @google/genai SDK (NOT deprecated @google/generative-ai). Text generation, multimodal (images/video/audio/PDFs), function calling, thinking mode, streaming. 1M input tokens. Prevents 14 documented errors. Use when: Gemini integration, multimodal AI, reasoning with thinking mode. Troubleshoot: SDK deprecation, model not found, context window, function calling errors, streaming corruption, safety settings, rate limits.
Configure notification preferences in Novu at the workflow and subscriber level. Set default channel preferences (email, SMS, push, chat, in-app), mark preferences as read-only or subscriber-editable, and manage subscriber-specific overrides. Use when setting up notification opt-in/opt-out, configuring per-channel delivery preferences, or building a preferences management UI.
Explore a large codebase in parallel by launching multiple explore subagents that each investigate a different area simultaneously. Use when onboarding onto a new project, understanding architecture, or investigating a cross-cutting concern.
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.
