USE FOR web search. Returns ranked results with snippets, URLs, thumbnails. Supports freshness filters, SafeSearch, Goggles for custom ranking, pagination. Primary search endpoint.
Guidance for using the Google Play Developer CLI (flags, output formats, auth, pagination). Use when asked to run or design gpd commands for Play Console workflows.
GraphQL API design. Covers schema, queries, mutations, and resolvers. Use when building or consuming GraphQL APIs. USE WHEN: user mentions "GraphQL", "schema definition", "resolvers", "mutations", "queries", "DataLoader", "N+1 problem", asks about "how to design GraphQL API", "GraphQL schema", "GraphQL authentication", "GraphQL pagination", "Apollo Server" DO NOT USE FOR: REST APIs - use `rest-api` instead; tRPC - use `trpc` instead; GraphQL code generation - use `graphql-codegen` instead
Generates optimized read queries using Dapper. Includes multi-mapping for joins, pagination, dynamic filtering, CTEs, and best practices for high-performance data access.
Test and troubleshoot Enable Banking sandbox integrations, ASPSP sandbox behavior, Mock ASPSP setup, sandbox credentials, AIS authorization simulation, transaction pagination quirks, and sandbox limitations. Use when Codex needs to choose a sandbox bank, find test credentials, explain why a sandbox ASPSP behaves differently from production, configure Mock ASPSP data, or implement project code that must work against Enable Banking sandbox environments.
Querying Stellar chain data via Stellar RPC (preferred) and Horizon (legacy). Covers RPC JSON-RPC methods, Horizon REST endpoints, streaming, pagination, historical queries, Hubble/Galexie for deep history, and the RPC/Horizon migration story. Use when reading balances, transactions, operations, ledgers, contract events, or building any indexer/analytics workflow.
Use this skill whenever building, reviewing, or refactoring React components that fetch data from APIs — especially at scale (recommender carousels, infinite feeds, pages with many parallel fetches, dashboards). Covers request orchestration (parallelism, batching, deduplication), cache strategy (keys, normalization, staleTime, SWR), backend protection (concurrency caps, debounce/throttle, jittered retries, circuit breakers), prefetching (route loaders, hover/intent, idle, server hydration), failure resilience (AbortController, timeouts, error boundaries, stale fallback, idempotent mutations), and feed/carousel patterns (virtualization, cursor pagination, summary/detail split). Trigger even if the user doesn't explicitly mention "performance" or "scale" — any non-trivial React data-fetching code benefits from these patterns. Includes 5 ready-to-use scaffolding templates (resource query hook, carousel data loader, infinite feed, hover-prefetch link, request collapser).
TanStack Table v8 headless data tables with server-side features for Cloudflare Workers + D1. Use for pagination, filtering, sorting, virtualization, or encountering state management, TanStack Query coordination, URL sync errors.
Build Hotwire navigation and content-discovery flows: Turbo Frame pagination, tabbed navigation, lazy loading, faceted filtering/search, cache lifecycle, scroll restoration, and visit/render control. Prefer this skill when the core problem is request/response navigation state and browser history behavior. Use hwc-forms-validation for form validation and inline edit flows, hwc-realtime-streaming for WebSocket/Turbo Stream push updates, hwc-media-content for image/video/audio features, hwc-ux-feedback for generic loading/progress/transition polish, and hwc-stimulus-fundamentals for Stimulus APIs not centered on navigation.
Query the DatoCMS Content Delivery API (CDA) — the read-only GraphQL API — using @datocms/cda-client. Use when users ask for GraphQL content reads: fetching posts/pages/projects, filtering by date/text/fields, sorting/order, pagination/load-more, text pattern matching via regex filters, localization and fallback locales, modular content fragments, Structured Text (DAST) with blocks/inline records, responsive images (srcset/blur-up/imgix), SEO metadata (_seoMetaTags, favicons, global SEO), video/Mux fields, draft or preview reads, environment-targeted reads, cache tags via rawExecuteQuery, and Content Link metadata for visual editing. Also use for CDA query type generation with gql.tada or GraphQL Code Generator.
REST and GraphQL API design principles. Covers resource modeling, endpoint design, error handling, versioning, pagination, authentication patterns, and API evolution strategies.
Use when you need to design, review, or improve REST APIs with Spring Boot — including HTTP methods, resource URIs, status codes, DTOs, versioning, deprecation and sunset headers, content negotiation (JSON and vendor media types), ISO-8601 instants in DTOs, pagination/sorting/filtering, Bean Validation at the boundary, idempotency, ETag concurrency, HTTP caching, error handling, security, API documentation, controller advice, and problem details for errors.
