Activates when user says "analyze BTC", "what's the trend", "check this chart", mentions ticker symbols, or uses /trading:analyze command.

effect-ts-resources
by mrevanzak
Use when managing resource lifecycles (DB connections, file handles, sockets) where cleanup must be guaranteed despite failures, interruptions, or potential resource leaks.
fastapi-patterns
by hieutrtr
FastAPI framework mechanics and advanced patterns. Use when configuring middleware, creating dependency injection chains, implementing WebSocket endpoints, customizing OpenAPI documentation, setting up CORS, building authentication dependencies (JWT validation, role-based access), implementing background tasks, or managing application lifespan (startup/shutdown). Does NOT cover basic endpoint CRUD or repository/service patterns (use python-backend-expert) or testing (use pytest-patterns).
moon-clean-skill
by imoonwander
Clean up disk space and uninstall macOS apps safely — disk usage checkup, app bundle and leftover review, system/app caches, dev junk (node_modules/Xcode/Docker/package-manager caches), large-file discovery, and dedup/leftover cleanup of agent skills directories; always checks and confirms before deleting. Use when the user says "disk full", "clean my mac", "free up space", "clear cache", "uninstall/remove an app", "my computer is slow, clean it up", or in Chinese "磁盘满了""清理电脑/Mac""释放空间""清理缓存""卸载/删除应用或软件""skills 太乱了清理一下", or when the system warns about low storage.
conflux-rust-integration-test
by conflux-fans
Create or update pytest-based integration tests for conflux-rust, including adding new test modules under integration_tests/tests, using ConfluxTestFramework and pytest fixtures (network, cw3/ew3, accounts, internal_contracts), customizing framework_class and fixtures, and running/debugging tests with pytest and xdist options.
nextjs-app-router-data-fetching
by Agentient
Data fetching patterns for Next.js 14+ App Router including async Server Components and Server Actions. PROACTIVELY activate for: (1) fetching data in Server Components, (2) implementing Server Actions for mutations, (3) configuring caching and revalidation. Triggers: "fetch data", "server action", "revalidate"
cache-strategy
by manastalukdar
Implement caching strategies for HTTP, service workers, and memoization
performance-audit
by truongnat
Audit and optimize application performance across frontend, backend, and database layers. Identifies bottlenecks, provides actionable optimization recommendations, and measures improvements. Use when the app feels slow, Lighthouse scores are low, or API response times exceed targets.
orthogonalize-pr
by corygabrielsen
Identify and separate orthogonal (independent) change sets within a decomposed PR. Creates branches for each set that could theoretically be reviewed or merged separately.
commit

Triggers on: turbo.json, task pipelines, dependsOn, caching, remote cache, the "turbo" CLI, --filter, --affected, CI optimization, environment variables, internal packages, monorepo structure/best practices, and boundaries. Use when user: configures tasks/workflows/pipelines, creates packages, sets up monorepo, shares code between apps, runs changed/affected packages, debugs cache, or has apps/packages directories.
@tank/system-design

Practical system design for production distributed systems. Covers scalability patterns (load balancing, horizontal scaling, CDN, auto-scaling), data layer design (database selection, replication, sharding, consistency models, CAP theorem applied), caching strategies (cache-aside, write-through, invalidation, stampede prevention), messaging and async patterns (queues vs streams, event-driven architecture, CQRS, saga pattern, delivery guarantees), reliability (circuit breakers, bulkheads, retries, rate limiting, timeouts, chaos engineering), service architecture (monolith vs microservices, API gateway, service mesh, distributed transactions), and capacity planning (back-of-envelope estimation, SLOs/SLIs, monitoring, distributed tracing).
