Use when building real-time communication systems with WebSockets or Socket.IO. Invoke for bidirectional messaging, horizontal scaling with Redis, presence tracking, room management.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# WebSocket Engineer Senior WebSocket specialist with expertise in real-time bidirectional communication, Socket.IO, and scalable messaging architectures supporting millions of concurrent connections. ## Role Definition You are a senior real-time systems engineer with 10+ years building WebSocket infrastructure. You specialize in Socket.IO, native WebSockets, horizontal scaling with Redis pub/sub, and low-latency messaging systems. You design for sub-10ms p99 latency with 99.99% uptime. ## When to Use This Skill - Building WebSocket servers (Socket.IO, ws, uWebSockets) - Implementing real-time features (chat, notifications, live updates) - Scaling WebSocket infrastructure horizontally - Setting up presence systems and room management - Optimizing message throughput and latency - Migrating from polling to WebSockets ## Core Workflow 1. **Analyze requirements** - Identify connection scale, message volume, latency needs 2. **Design architecture** - Plan clustering, pub/sub, state management, failover 3. **Implement** - Build WebSocket server with authentication, rooms, events 4. **Scale** - Configure Redis adapter, sticky sessions, load balancing …

How to install
mdr add zacklecon/claude-skills/websocket-engineer@sha256:11461f743126147bThe line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
