Use this skill when working on the Svelte 5 app in ClientApp — adding routes, creating feature slices, organizing shared components, or understanding the ClientApp directory layout. Covers route groups, $lib conventions, barrel exports, API client organization, and vertical slice architecture. Apply when deciding where to place new files or components. The legacy Angular app that still powers most of the site lives beside it in ClientApp.angular.
Use this skill when writing or reviewing TypeScript code in the frontend to follow project conventions. Covers naming standards (kebab-case files), import patterns, error handling, type safety (no any), and ESLint/Prettier configuration. Apply when authoring new TypeScript files, reviewing code style, or resolving linting issues.
Use this skill when working on the ASP.NET Core backend — adding controllers, repositories, validators, authorization, WebSocket endpoints, or Aspire orchestration. Apply when modifying project layering (Core, Insulation, Web, Job), configuring services, returning ProblemDetails errors, or understanding how the backend is structured.
Use this skill when building or reviewing frontend components for accessibility compliance. Covers WCAG 2.2 AA standards including semantic HTML, keyboard navigation, ARIA patterns, focus management, screen reader support, and form accessibility. Apply when creating new UI components, fixing accessibility bugs, adding skip links or focus traps, or ensuring inclusive markup — even if the user doesn't explicitly mention "a11y" or "WCAG."
Use this skill when writing or modifying C# tests — unit tests, integration tests, or test fixtures. Covers xUnit patterns, AppWebHostFactory for integration testing, FluentClient for API assertions, ProxyTimeProvider for time manipulation, and test data builders. Apply when adding new test cases, debugging test failures, or setting up test infrastructure.
Use this skill when querying, counting, patching, or paginating data through Foundatio.Repositories Elasticsearch abstractions. Covers filter expressions, aggregation queries, partial and script patches, and search-after pagination. Apply when working with any repository method — never use raw IElasticClient directly.
Use this skill when working with Foundatio infrastructure abstractions — caching, queuing, messaging, file storage, locking, or background jobs. Apply when using ICacheClient, IQueue, IMessageBus, IFileStorage, ILockProvider, or IJob, or when implementing retry/resilience patterns. Covers both in-memory and production (Redis, Elasticsearch) implementations.
Use this skill when writing or running frontend unit and component tests with Vitest and Testing Library. Covers render/screen/fireEvent patterns, vi.mock for mocking, and the AAA (Arrange-Act-Assert) test structure. Apply when adding test coverage for Svelte components, debugging test failures, or setting up test utilities.
