Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/aj-geddes/useful-ai-prompts --skill real-time-features- 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 real-time-features automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.

Real-Time Features
Table of Contents
Overview
Implement real-time bidirectional communication between clients and servers for instant data synchronization and live updates.
When to Use
- Chat and messaging applications
- Live dashboards and analytics
- Collaborative editing (Google Docs-style)
- Real-time notifications
- Live sports scores or stock tickers
- Multiplayer games
- Live auctions or bidding systems
- IoT device monitoring
- Real-time location tracking
Quick Start
Minimal working example:
// server.ts
import WebSocket, { WebSocketServer } from "ws";
import { createServer } from "http";
interface Message {
type: "join" | "message" | "leave" | "typing";
userId: string;
username: string;
content?: string;
timestamp: number;
}
interface Client {
ws: WebSocket;
userId: string;
username: string;
roomId: string;
}
class ChatServer {
private wss: WebSocketServer;
private clients: Map<string, Client> = new Map();
private rooms: Map<string, Set<string>> = new Map();
constructor(port: number) {
// ... (see reference guides for full implementation)

Best Practices
✅ DO
- Implement reconnection logic with exponential backoff
- Use heartbeat/ping-pong to detect dead connections
- Validate and sanitize all messages
- Implement authentication and authorization
- Handle connection limits and rate limiting
- Use compression for large payloads
- Implement proper error handling
- Monitor connection health
- Use rooms/channels for targeted messaging
- Implement graceful shutdown
❌ DON'T
- Send sensitive data without encryption
- Keep connections open indefinitely without cleanup
- Broadcast to all users when targeted messaging suffices
- Ignore connection state management
- Send large payloads frequently
- Skip message validation
- Forget about mobile/unstable connections
- Ignore scaling considerations
FAQ

How do I install real-time-features?
Run npx skills add https://github.com/aj-geddes/useful-ai-prompts --skill real-time-features 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/real-time-features/ (personal) or .claude/skills/real-time-features/ (project).
Which AI agents can use real-time-features?
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 real-time-features 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 real-time-features?

Popular backend & apis skills
find-skills
vercel-labs/skills
Helps users discover and install agent skills when they ask questions like "how do I do X", "find a skill for X", "is there a skill that can...", or express interest in extending capabilities. This skill should be used when the user is looking for functionality that might exist as an installable skill.
entra-app-registration
microsoft/azure-skills
Guides Microsoft Entra ID app registration, OAuth 2.0 authentication, and MSAL integration. USE FOR: create app registration, register Azure AD app, configure OAuth, set up authentication, add API permissions, generate service principal, MSAL example, console app auth, Entra ID setup, Azure AD authentication. DO NOT USE FOR: Key Vault secrets (use azure-keyvault-expiration-audit), general Azure resource security guidance.
google-agents-cli-adk-code
google/agents-cli
This skill should be used when the user wants to "write agent code", "build an agent with ADK", "add a tool", "create a callback", "define an agent", "use state management" — in a project that needs ADK (Agent Development Kit) API patterns and code examples. It provides a quick reference for agent types, tool definitions, orchestration patterns, callbacks, state management, the graph Workflow API, and reference recipes to study. Do NOT use for scaffolding (use google-agents-cli-scaffold) or deployment (use google-agents-cli-deploy).
embedded-captions
heygen-com/hyperframes
Add captions or subtitles to an existing single-subject talking-head video without editing the footage. Use for plain verbatim captions, cinematic captions embedded behind the subject, VFX captions, “炸/特效/酷炫字幕,” or a named identity from the 35-style catalog. Route by visual identity, not by backend engine. The quiet anchor rail is the default; embed every word only when the user explicitly wants a fully cinematic treatment. The workflow runs locally end to end, including transcription and subject matting; split multi-shot footage before applying it.
