What it does

When installed, the agent answers WebSocket and Socket.IO questions with a structured approach: it plans connection scale and architecture, writes server and client code with token authentication, room management and presence tracking, and explains how to scale across several servers using Redis. It also reminds the agent of practical concerns such as heartbeats, reconnection with backoff, sticky sessions, cleanup of dead connections, and load testing before production.

Great for

  • Developers building chat, live dashboards, or collaborative apps that need real-time two-way messaging
  • Teams moving a Socket.IO service from one server to several behind a load balancer
  • Engineers who want a checklist-driven review of WebSocket auth, reconnection and monitoring

Skip it if

  • Simple one-way updates where Server-Sent Events or polling would do; the skill's own alternatives reference covers this, so check it first
  • Production deployments without review: the code samples are illustrative and the skill itself says to load test before going live, so security-critical auth code should be audited by a person

Try asking

  • “Build a Socket.IO chat server with JWT authentication and room join/leave events”
  • “Set up Redis adapter scaling for my WebSocket server across three instances with sticky sessions”
  • “Add presence tracking so I can see which users are online in each room”
  • “Write a client that reconnects with exponential backoff and queues messages while offline”

  2. 2

    Add it to your agent

    Claude Code (all projects)

    mkdir -p ~/.claude/skills && unzip websocket-engineer.zip -d ~/.claude/skills/

    Claude Code / Agent SDK (this project only)

    mkdir -p .claude/skills && unzip websocket-engineer.zip -d .claude/skills/

    Claude apps (web/desktop): Settings → Capabilities → Skills → Upload skill, and choose the ZIP.

  3. 3

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Name your stack up front (for example Socket.IO vs raw ws, and your load balancer) so the agent picks matching examples
  • Ask for the security reference explicitly when working on authentication, rate limiting or CORS
  • Have the agent write its own tests for auth rejection and reconnection before deploying; review any generated code that handles secrets
