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
   • Prefer deploying to CloudBase using manageAgent MCP tool (see agent-deployment)
   • Before deploy, read Dependency Alignment Policy in agent-deployment to avoid cloud build dependency errors

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
