Caching

Master Redis Cluster - horizontal scaling, hash slots, resharding, cluster management, and distributed architecture

List cache entries with filtering, sorting, and freshness status.Delegates to fractary CLI for actual cache operations.

Manages Service Worker updates securely with cache versioning and offline tests. Use when modifying SW, adding resources, or changing cache strategy

Django Redis caching with django-cacheops. This skill should be used when implementing caching, adding cache invalidation, optimizing API performance, modifying models that affect cached data, or debugging cache-related issues in the Django backend.

Use when adding caching, optimizing performance, or debugging cache issues - validates invalidation strategies, TTL settings, key collision prevention, and memory management to prevent stale data and cache stampedes

End Claude Code session with Beads sync and summary. MUST BE USED when user says they're done, ending session, or logging off. Guarantees Beads export to git, shows session stats, and suggests next ready work. Handles cleanup and context saving. Use when user says "goodbye", "bye", "done for now", "logging off", or when user mentions end-of-session, session termination, cleanup, context saving, bd sync, or export operations.

Integrate Redis-compatible Vercel KV for caching, session management, and rate limiting in Next.js applications. Powered by Upstash with strong consistency and TTL support.Use when implementing cache strategies, storing temporary data with expiration, building rate limiters, or troubleshooting missing environment variables, serialization errors, or rate limit issues.

Master Redis Lists and Sets - queues, stacks, unique collections, set operations, and real-world implementation patterns

Write tests for MockDB (in-memory) repository implementations. Use when testing MockDB repositories, in-memory data access, or mock repository behavior. Triggers on "test mockdb", "mockdb tests", "test mock repository".

Complete epic with cleanup and archiving, or verify feature already closed. MUST BE USED when finishing epics/features.For epics: Verifies children closed, archives docs, caches to Serena, closes epic.For features/tasks/bugs: Verifies already closed (from PR creation), archives docs, caches to Serena.Non-epic issues must be closed at PR creation time (atomic merge pattern).Use when user says "I'm done with this epic", "finish the feature", "finish this epic", "archive this epic",or when user mentions epic completion, cleanup, archiving, feature finalization, or closing work.

Staging and production deployment using Laravel Deployer with health checks, cache management, and rollback support (HUMAN-ONLY execution)

Build Next.js 16 apps with App Router, Server Components/Actions, Cache Components ("use cache"), and async route params. Includes proxy.ts (replaces middleware.ts) and React 19.2.Use when: building Next.js 16 projects, or troubleshooting async params (Promise types), "use cache" directives, parallel route 404s (missing default.js), or proxy.ts CORS.

Executes GitHub operations via gh CLI wrapper. Use when managing issues, pull requests, workflows, CI runs, projects, releases, cache, labels, or searching repositories and code.

Bull queue setup, worker processes, job lifecycle, error handling, retries, progress reporting, Redis connection management, and queue patterns for OCR and knowledge processing

Create epic-specific documentation skill with external reference docs. MUST BE USED for caching external docs.Fetches URLs, caches full content, uses documentation-engineer to generate cohesive summaries, and creates auto-activating skill.Use when starting work on epic that requires external documentation context (API docs, tool guides, reference materials),or when user mentions "cache docs", "external docs", "API documentation", URLs for docs,documentation needs, reference materials, knowledge caching, or epic context documentation.

Use when code changes touch database, cache, queue, or other service-dependent components - enforces testing against real local services instead of mocks

Master Redis advanced data types - Bitmaps, HyperLogLog, Streams, and Geospatial indexes for specialized use cases

Manage server state in React with TanStack Query v5. Set up queries with useQuery, mutations with useMutation, configure QueryClient caching strategies, implement optimistic updates, and handle infinite scroll with useInfiniteQuery.Use when: setting up data fetching in React projects, migrating from v4 to v5, or fixing object syntax required errors, query callbacks removed issues, cacheTime renamed to gcTime, isPending vs isLoading confusion, keepPreviousData removed problems.

Master scalability patterns with load balancing, caching, database scaling, microservices, and horizontal scaling strategies.

Master Redis Strings - SET, GET, INCR, DECR, atomic counters, binary-safe operations, and caching patterns
