Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/aj-geddes/useful-ai-prompts --skill websocket-implementation- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads websocket-implementation automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.

WebSocket Implementation
Table of Contents
Overview
Build scalable WebSocket systems for real-time communication with proper connection management, message routing, error handling, and horizontal scaling support.
When to Use
- Building real-time chat and messaging
- Implementing live notifications
- Creating collaborative editing tools
- Broadcasting live data updates
- Building real-time dashboards
- Streaming events to clients
- Live multiplayer games
Quick Start
Minimal working example:
const express = require("express");
const http = require("http");
const socketIo = require("socket.io");
const redis = require("redis");
const app = express();
const server = http.createServer(app);
const io = socketIo(server, {
cors: { origin: "*" },
transports: ["websocket", "polling"],
reconnection: true,
reconnectionDelay: 1000,
reconnectionDelayMax: 5000,
reconnectionAttempts: 5,
});
// Redis adapter for horizontal scaling
const redisClient = redis.createClient();
const { createAdapter } = require("@socket.io/redis-adapter");
io.adapter(createAdapter(redisClient, redisClient.duplicate()));
// Connection management
const connectedUsers = new Map();
// ... (see reference guides for full implementation)

Best Practices
✅ DO
- Implement proper authentication
- Handle reconnection gracefully
- Manage rooms/channels effectively
- Persist messages appropriately
- Monitor active connections
- Implement presence features
- Use Redis for scaling
- Add message acknowledgment
- Implement rate limiting
- Handle errors properly
❌ DON'T
- Send unencrypted sensitive data
- Keep unlimited message history in memory
- Allow arbitrary room/channel creation
- Forget to clean up disconnected connections
- Send large messages frequently
- Ignore network failures
- Store passwords in messages
- Skip authentication/authorization
- Create unbounded growth of connections
- Ignore scalability from day one
FAQ

How do I install websocket-implementation?
Run npx skills add https://github.com/aj-geddes/useful-ai-prompts --skill websocket-implementation in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/websocket-implementation/ (personal) or .claude/skills/websocket-implementation/ (project).
Which AI agents can use websocket-implementation?
Any agent that supports the open Agent Skills format (a folder with a SKILL.md file), including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, Windsurf, Cline, OpenCode and more.
Is websocket-implementation safe to install?
No partner security audit is available yet. Skills can run commands and scripts, so read the SKILL.md and any bundled files before installing.
Who maintains websocket-implementation?
It is published by aj-geddes in aj-geddes/useful-ai-prompts. It has 663 recorded installs.

Popular ai & agents skills
google-agents-cli-publish
google/agents-cli
This skill should be used when the user wants to "publish an agent", "publish my ADK agent", "register an agent with Gemini", "publish to Gemini" (formerly Gemini Enterprise), or needs guidance on the agents-cli publish gemini command. Also use when the user wants to "manage agents in Agent Registry", "list/update/delete registered agents", or "register an MCP server". Covers ADK vs A2A registration modes, programmatic and interactive usage, flag reference, auto-detection from deployment metadata, Agent Registry fleet management, and troubleshooting. Part of the agents-cli skills suite. Do NOT use for deployment (use google-agents-cli-deploy).
google-agents-cli-eval
google/agents-cli
This skill should be used when the user wants to "run an evaluation", "evaluate my agent", "evaluate my ADK agent", "write an eval dataset", "analyze eval failures", "compare eval results", "optimize agent", or needs guidance on the Gemini platform eval methodology and the Quality Flywheel. Covers eval metrics, dataset schema, LLM-as-judge scoring, and common failure causes. Applies to any agents-cli project, whatever framework the agent is written in. Do NOT use for agent API code patterns (ADK: use google-agents-cli-adk-code), deployment (use google-agents-cli-deploy), or project scaffolding (use google-agents-cli-scaffold).
skill-creator
anthropics/skills
Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit, or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.
codex-pet
prime-skills/runcomfy-agent-skills
Codex Pet generator on RunComfy. Build a Codex-compatible Codex Pet spritesheet.webp + pet.json from a single reference image, drop it into ${CODEXHOME:-$HOME/.codex}/pets/ / and Codex picks it up as a custom Codex Pet next to the 8 built-ins. This skill produces the exact Codex Pet atlas Codex expects (1536x1872 PNG/WebP, 8 cols x 9 rows, 192x208 cells, 9 animation states — idle, running-right, running-left, waving, jumping, failed, waiting, running, review). Calls OpenAI GPT Image 2 edit ONCE via the local RunComfy CLI as runcomfy run openai/gpt-image-2/edit to produce a canonical Codex Pet pose, then assembles all 9 animation rows programmatically with ImageMagick micro-transforms — no Codex Pro, no $imagegen, no OPENAIAPIKEY required, only RUNCOMFYTOKEN. Triggers on "codex pet", "create codex pet", "make codex pet", "hatch codex pet", "/hatch image", "desktop pet codex", "codex pets", "spritesheet.webp", or any explicit ask to build a custom pet for OpenAI Codex.
