websocket-engineer
Use when building real-time communication systems with WebSockets or Socket.IO. Invoke for bidirectional messaging, horizontal scaling with Redis, presence tracking, room management.
npx skills add Jeffallan/claude-skills --skill websocket-engineer --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# WebSocket Engineer ## 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. **Validate locally** — Test connection handling, auth, and room behavior before scaling (e.g., `npx wscat -c ws://localhost:3000`); confirm auth rejection on missing/invalid tokens, room join/leave events, and message delivery 5. **Scale** — Verify Redis connection and pub/sub round-trip before enabling the adapter; configure sticky sessions and confirm with test connections across multiple instances; set up load balancing 6. **Monitor** — Track connections, latency, throughput, error rates; add alerts for connection-count spikes and error-rate thresholds ## Reference Guide Load detailed guidance based on context: | Topic | Reference | Load When | |-------|-----------|-----------| | Protocol | `references/protocol.md` | WebSocket handshake, frames, ping/pong, close codes | | Scaling | `references/scaling.md` | Horizontal scaling, Redis pub/sub, sticky sessions | | Patterns | `references/patterns.md`

What does the websocket-engineer skill do?
Use when building real-time communication systems with WebSockets or Socket.IO. Invoke for bidirectional messaging, horizontal scaling with Redis, presence tracking, room management.
How do I install it?
Run `npx skills add Jeffallan/claude-skills --skill websocket-engineer --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From Jeffallan/claude-skills, a repository with 10,871 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
