Deep Agents TypeScript quickstart

createDeepAgent

Local setup constraints

1. Ask which provider/model to use. Showcase that Deep Agents are model-agnostic. Suggested prompt:

   Which model should this agent use? Pass a

   provider:model

   string — e.g.

   openai:gpt-5.5

   ,

   anthropic:claude-sonnet-5

   ,

   google-genai:gemini-3.5-flash

   . Default if you're unsure:

   anthropic:claude-sonnet-5

   .
   We'll use that provider's built-in web search (no separate search API key).

2. Create a new directory (e.g.

   deep-agent/

   ) and do all work there — do not pollute the open project.
3. Do not use Tavily (or

   @langchain/tavily

   ). Replace the quickstart's search tool with the chosen provider's built-in web search. Look up the current export/tool shape on that provider's LangChain docs (examples as of writing — re-check if needed):

   Provider	Built-in search tool
   Anthropic	@langchain/anthropic tools.webSearch_*() (or equivalent dict)
   OpenAI	{ type: "web_search" }
   Google	{ google_search: {} }

   Prefer Anthropic / OpenAI / Google so provider search is available. Only secret: that provider's API key in

   .env

   (gitignored). Skip LangSmith tracing unless they ask.
4. Install packages from the quickstart minus Tavily; add the provider package for their model.
5. Run the research example, show output, then stop. Point to

   deep-agents-core

   / customization / Managed Deep Agents for next steps.
