Arma Reforger Workbench workflow, testing guidelines, and debugging patterns
Guide installation of project dependencies and toolchains. Use when a junior developer is stuck setting up the environment.
Generate a small helper script for repetitive tasks. Use when a junior developer needs a quick automation snippet.
Use for custom storefronts requiring direct GraphQL queries/mutations for data fetching and cart operations. Choose this when you need full control over data fetching and rendering your own UI. NOT for Web Components - if the prompt mentions HTML tags like <shopify-store>, <shopify-cart>, use storefront-web-components instead.
Build retail point-of-sale applications using Shopify's POS UI components. These components provide a consistent and familiar interface for POS applications. POS UI Extensions also supports scaffolding new POS extensions using Shopify CLI commands. Keywords: POS, Retail, smart grid
Build your app's primary user interface embedded in the Shopify admin. If the prompt just mentions `Polaris` and you can't tell based off of the context what API they meant, assume they meant this API.
Build custom functionality that merchants can install at defined points on the Order index, Order status, and Profile pages in customer accounts. Customer Account UI Extensions also supports scaffolding new customer account extensions using Shopify CLI commands.
Shopify Functions allow developers to customize the backend logic that powers parts of Shopify. Available APIs: Discount, Cart and Checkout Validation, Cart Transform, Pickup Point Delivery Option Generator, Delivery Customization, Fulfillment Constraints, Local Pickup Delivery Option Generator, Order Routing Location Rule, Payment Customization
Hydrogen storefront implementation cookbooks. Some of the available recipes are: B2B Commerce, Bundles, Combined Listings, Custom Cart Method, Dynamic Content with Metaobjects, Express Server, Google Tag Manager Integration, Infinite Scroll, Legacy Customer Account Flow, Markets, Partytown + Google Tag Manager, Subscriptions, Third-party API Queries and Caching. MANDATORY: Use this API for ANY Hydrogen storefront question - do NOT use Storefront GraphQL when 'Hydrogen' is mentioned.
MUST be used first when prompts mention Metafields or Metaobjects. Use Metafields and Metaobjects to model and store custom data for your app. Metafields extend built-in Shopify data types like products or customers, Metaobjects are custom data types that can be used to store bespoke data structures. Metafield and Metaobject definitions provide a schema and configuration for values to follow.
Run a validated Admin GraphQL operation against a specific store using Shopify CLI. Use this when the user wants an executable store workflow, not just the query or mutation text. If the answer should include `shopify store auth` and `shopify store execute`, choose this API. Choose this for 'my store', 'this store', a store domain, product reads on a merchant store, low-inventory lookups, product updates, and warehouse/location inventory changes. Examples: 'Show me the first 10 products on my store', 'Find products with low inventory on my store', 'Set inventory at the Toronto warehouse so SKU ABC-123 is 12'.
Software Mansion's best practices for gestures in React Native apps using React Native Gesture Handler. Use when implementing tap, pan, pinch, rotation, swipe, long press, fling, hover, drag, or any touch interaction. Trigger on: 'gesture handler', 'GestureDetector', 'tap gesture', 'pan gesture', 'pinch gesture', 'rotation gesture', 'long press', 'fling', 'hover gesture', 'swipe', 'pinch to zoom', 'drag', 'touch handling', 'Pressable', 'RectButton', 'Swipeable', 'DrawerLayout', 'VirtualGestureDetector', or any request to handle user touch input in a React Native app.
Software Mansion's best practices for audio in React Native using react-native-audio-api. Covers audio playback (buffer sources, oscillators, streaming), recording (file, callback, graph), audio effects (gain, filters, delay, convolver, panner, waveshaper), real-time analysis and visualization, audio worklets (custom synthesis, UIRuntime/AudioRuntime), system integration (sessions, interruptions, permissions), and testing. Trigger on: react-native-audio-api, AudioContext, AudioRecorder, AudioBuffer, AudioBufferSourceNode, AudioBufferQueueSourceNode, OscillatorNode, StreamerNode, GainNode, BiquadFilterNode, DelayNode, ConvolverNode, StereoPannerNode, WaveShaperNode, AnalyserNode, AudioParam, AudioManager, PlaybackNotificationManager, RecordingNotificationManager, WorkletNode, WorkletSourceNode, WorkletProcessingNode, audio playback, record audio, microphone, waveform, audio visualization, audio streaming, audio worklet, or any React Native feature that captures, processes, or emits sound.
Best practices for building on-device AI features in React Native using React Native ExecuTorch. Use when the user wants to add AI to a mobile app without cloud dependencies: AI chatbots and assistants, image classification, object detection, text recognition and document parsing (OCR), style transfer, image generation, speech-to-text transcription, text-to-speech synthesis, voice activity detection, semantic search with embeddings, real-time camera AI with VisionCamera, or vision-language image understanding. Also use when the user mentions offline AI, on-device ML, privacy-preserving AI, reducing cloud API costs or latency, running models locally on mobile, or downloading and managing ML models. Covers react-native-executorch hooks (useLLM, useClassification, useObjectDetection, useOCR, useSemanticSegmentation, useInstanceSegmentation, useStyleTransfer, useTextToImage, useImageEmbeddings, useSpeechToText, useTextToSpeech, useVAD, useTextEmbeddings, useExecutorchModule), tool calling, structured output, VLMs
Use when: running an ad hoc Node.js script, using node -e for inspection or file transforms, creating a temporary .cjs helper, or avoiding Git Bash quoting and history-expansion issues on Windows. Keywords: node script, node -e, temporary script, .cjs, Git Bash, history expansion, JSON transform, one-off Node command.
Build or maintain a Codex-native self-improving memory loop using global `AGENTS.md`, a persistent memories directory, and optional nightly refinement automation. Use when Codex needs to adapt OpenClaw-style self-improvement ideas to Codex, set up long-term user/profile memory, create `PROFILE.md` / `ACTIVE.md` / `LEARNINGS.md` / `ERRORS.md` / `FEATURE_REQUESTS.md`, add promotion rules from raw learnings into active guidance, or create a recurring memory-refinement automation.
Build Stellar blockchain applications in Flutter/Dart using stellar_flutter_sdk. Use when generating Dart code for transaction building, signing, Horizon API queries, Soroban RPC, smart contract deployment and invocation, XDR encoding/decoding, and SEP protocol integration. Covers 26+ operations, 50 Horizon endpoints, 12 RPC methods, and 18 SEP implementations with async/await and Stream patterns across Android, iOS, Web, and Desktop.
Generate complete production-ready SaaS boilerplate with authentication, database schemas, billing integration (Stripe), multi-tenancy, API routes, dashboard UI, and deployment configuration. Supports Next.js App Router, TypeScript, Tailwind, shadcn/ui, Drizzle ORM, and multiple auth/payment providers. Use when starting a new SaaS product, subscription app, or multi-tenant platform.
Use when you need to read, understand, or reference the native iOS AdaptySDK-iOS source code — for understanding bridge contracts, porting new features, debugging native behavior, or checking JSON request/response formats
This skill should be used when the user asks to "build web automation scripts", "check browser automation for detection", "generate web scraping code", "create form filling automation", or "build anti-detection browser scripts".
Use this skill for engineering tasks that require planning with write_todos, controlled file edits, and final verification.
