# 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

## Quick Start

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

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