Caching
Caching strategies and implementation
Uses and selection guide
Use these skills when designing service interfaces, changing data models or integrating identity and cache layers. Check the supported database or provider, migration behavior and required credentials before choosing a workflow.
data-fetching-architecture
by lobehub
'LobeHub data-fetching pipeline guide. Use for service layer, Zustand store, SWR, lambdaClient, useClientDataSWR, useFetchXxx hooks, or migrating useEffect fetches.'
account-state
by vitorpamplona
Account state and in-memory event store patterns in Amethyst. Use when working with Account.kt (per-user state objects — kind3FollowList, nip65RelayList, muteList, bookmarkState, each exposing a .flow StateFlow), LocalCache (the object-level event store backed by LargeCache), User/Note model classes, or any ViewModel that reads user-specific state. Covers how account events cascade from relay arrival to UI state, how to add a new account-scoped setting, and when to read from LocalCache vs subscribe to a StateFlow.
feed-patterns
by vitorpamplona
Feed composition and data-access layer patterns in Amethyst. Use when adding or modifying a feed (home, profile, hashtag, bookmarks, notifications, DMs, communities), working with the shared FeedFilter / AdditiveFeedFilter / ChangesFlowFilter / FeedContentState in commons/.../ui/feeds/, the Android-only AdditiveComplexFeedFilter / FilterByListParams in amethyst/.../ui/dal/, or extending the FeedViewModel family in commons/.../viewmodels/. Covers how feeds scan LocalCache, react to changes, apply ordering, and render through Compose.

compare-cache-runs
by tuist
Compares two tuist cache runs to identify cache hit rate changes and root-cause analysis of cache invalidation. Can be invoked with cache run IDs, dashboard URLs, or branch names.
compare-gradle-builds
by tuist
Compares two Gradle build runs to identify duration regressions, cache changes, and task outcome differences. Can be invoked with build IDs, dashboard URLs, or branch names.
analyze-selective-testing
by tuist
Analyzes Xcode selective testing effectiveness for a test run, showing which test targets were skipped or ran, and diagnosing regressions in test selection. Can compare two test runs to identify what changed.
compare-generations
by tuist
Compares two tuist generate runs to identify cache hit rate changes and root-cause analysis of cache invalidation. Can be invoked with generation IDs, dashboard URLs, or branch names.

performance-analysis
by rsmdt
Measurement approaches, profiling tools, optimization patterns, and capacity planning. Use when diagnosing performance issues, establishing baselines, identifying bottlenecks, or planning for scale. Always measure before optimizing.
architecture-selection
by rsmdt
System architecture patterns including monolith, microservices, event-driven, and serverless, with C4 modeling, scalability strategies, and technology selection criteria. Use when designing system architectures, evaluating patterns, or planning scalability.
high-perf-browser
by wondelai
'Optimize web performance through network protocols, resource loading, and browser rendering internals. Use when the user mentions "page load speed", "Core Web Vitals", "HTTP/2", "resource hints", "network latency", or "render blocking". Covers TCP/TLS optimization, caching strategies, WebSocket/SSE, and protocol selection. For UI visual performance, see refactoring-ui. For font loading, see web-typography.'
system-design
by wondelai
'Design scalable distributed systems using structured approaches for load balancing, caching, database scaling, and message queues. Use when the user mentions "system design", "scale this", "high availability", "rate limiter", or "design a URL shortener". Covers common system designs and back-of-the-envelope estimation. For data fundamentals, see ddia-systems. For resilience, see release-it.'
