ALWAYS load when working on the Reaparr media overview cache system — includes MediaQueryCache, cache invalidation, warmup, GetAllMediaByTypeEndpoint, library sync/refresh commands that invalidate the cache, the mediaOverviewStore frontend, or the MediaOverview component. Covers the stale-while-revalidate pattern, dirty-mark invalidation, background rebuilds, 503-on-miss behavior, auto-retry, and the key structure.
ALWAYS load for ANY frontend work in Reaparr — editing .vue files, composables, pages, stores, or any file under src/AppHost/ClientApp/. Defines mandatory standards: SFC block order, Nuxt auto-imports (what to omit), get/set for refs, useSubscription for RxJS, consola logging, Pinia-first logic, props/emits typing, styling, and cypress data-cy attributes.
Use when creating or updating C# backend unit tests in Reaparr, especially for handlers, services, endpoints, and jobs that must follow the project's TUnit, Shouldly, Moq, BaseUnitTest, naming, placement, and deterministic test-data conventions.
Use when doing any Reaparr backend work under src excluding ClientApp, backend tests, backend configs, C# code, FastEndpoints, EF Core, Quartz jobs, SignalR, command handlers, unit tests, integration tests, backend architecture, or backend reviews. This skill must always load before any narrower backend skill.
Use when creating, updating, debugging, or stabilizing Reaparr backend integration tests under tests/IntegrationTests, especially when failures involve async jobs, seeded data, fake Plex responses, filesystem behavior, or end-to-end API and database state validation.
Use when creating, debugging, or stabilizing Reaparr frontend Cypress integration tests, especially for flaky CI failures, uncaught app exceptions, route/port issues, and deterministic test hardening under src/AppHost/ClientApp/cypress.
Use when creating or updating Vitest unit tests for the Reaparr frontend (Nuxt/Vue/Pinia/RxJS stores), especially for store setup, actions, getters, and RxJS observable flows that must follow the project's boilerplate, path alias, mock data, and naming conventions.
Use when doing any Reaparr frontend work under src/AppHost/ClientApp, including Vue, Nuxt, TypeScript, Pinia, RxJS, Quasar, PrimeVue, Cypress, Vitest, frontend config, frontend reviews, debugging, refactors, and frontend test work. This skill must always load before any narrower frontend skill.
