Centrifugo Real-Time Messaging Integration
Centrifugo is a self-hosted, language-agnostic real-time messaging server. It handles persistent connections (WebSocket, SSE, HTTP-streaming, WebTransport, GRPC) and broadcasts messages via a channel-based PUB/SUB model. The application backend publishes to channels via Server API; Centrifugo delivers to online subscribers instantly.
Core Architecture
Backend App ──(HTTP/GRPC Server API)──> Centrifugo Cluster ──(WebSocket/SSE)──> Clients
│
Redis/NATS Broker
(for multi-node)
Key principle: All user-generated data flows through the application backend first (validate, persist, then publish to Centrifugo). Centrifugo is the transport layer, not the source of truth.

skill-best-practices
Authors and structures professional-grade agent skills following the agentskills.io spec. Use when creating new skill directories, drafting procedural instructions, or optimizing metadata for discoverability. Don't use for general documentation, non-agentic library code, or README files.
239architectural-analysis
Deep architectural audit focused on finding dead code, duplicated functionality, architectural anti-patterns, type confusion, and code smells. Use when user asks for architectural analysis, find dead code, identify duplication, or assess codebase health. Don't use for style/formatting issues, performance profiling, security audits, or feature-level code review.
199brainstorming
You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation.
174typescript-advanced
Master TypeScript's advanced type system including generics, conditional types, mapped types, template literals, and utility types for building type-safe applications. Use when implementing complex type logic, creating reusable type utilities, or ensuring compile-time type safety in TypeScript projects. Don't use for plain JavaScript, runtime validation libraries (Zod, Yup), or basic TypeScript syntax questions.

169no-workarounds
Enforce root-cause fixes over workarounds, hacks, and symptom patches in all software engineering tasks. Use when debugging issues, fixing bugs, resolving test failures, planning solutions, making architectural decisions, or reviewing code changes. Activates gate functions that detect and reject common workaround patterns such as type assertions, lint suppressions, error swallowing, timing hacks, and monkey patches. Don't use for trivial formatting changes or documentation-only edits.
