Cloudbase Agent (TypeScript)

TypeScript SDK for deploying AI agents as HTTP services using the AG-UI protocol.

Note: This skill is for TypeScript/JavaScript projects only.

When to use this skill

Use this skill for AI agent development when you need to:

• Deploy AI agents as HTTP services with AG-UI protocol support
• Build agent backends using LangGraph or LangChain frameworks
• Create custom agent adapters implementing the AbstractAgent interface
• Understand AG-UI protocol events and message streaming
• Build web UI clients that connect to AG-UI compatible agents
• Build WeChat Mini Program UIs for AI agent interactions

Do NOT use for:

• Simple AI model calling without agent capabilities (use ai-model-* skills)
• CloudBase cloud functions (use cloud-functions skill)
• CloudRun backend services without agent features (use cloudrun-development skill)

How to use this skill (for a coding agent)

1. Choose the right adapter

   • Use LangGraph adapter for stateful, graph-based workflows
   • Use LangChain adapter for chain-based agent patterns
   • Build custom adapter for specialized agent logic

2. Deploy the agent server

   • Use @cloudbase/agent-server to expose HTTP endpoints
   • Configure CORS, logging, and observability as needed
   • Deploy to CloudRun or any Node.js hosting environment

3. Build the UI client

   • Use @ag-ui/client for web applications
   • Use @cloudbase/agent-ui-miniprogram for WeChat Mini Programs
   • Connect to the agent server's /send-message or /agui endpoints

4. Follow the routing table below to find detailed documentation for each task

Routing

| Task | Read | |------|------| | Deploy agent server (@cloudbase/agent-server) | server-quickstart | | Use LangGraph adapter | adapter-langgraph | | Use LangChain adapter | adapter-langchain | | Build custom adapter | adapter-development | | Understand AG-UI protocol | agui-protocol | | Build UI client (Web or Mini Program) | ui-clients | | Deep-dive @cloudbase/agent-ui-miniprogram | ui-miniprogram |

Quick Start

import { run } from "@cloudbase/agent-server";
import { LanggraphAgent } from "@cloudbase/agent-adapter-langgraph";

run({
  createAgent: () => ({ agent: new LanggraphAgent({ workflow }) }),
  port: 9000,
});
