Privileged issue

  • I am a LangChain maintainer, or was asked directly by a LangChain maintainer to create an issue here.

Issue Content

Currently there's a bunch of tools and other integrations that use initialize_agent in their docs page (search langchain/docs for "initialize_agent")

This function has been deprecated since 0.1 and should be replaced with basic langgraph usage as a demo

Deprecated function: https://python.langchain.com/api_reference/langchain/agents/langchain.agents.initialize.initialize_agent.html

Example page using create_react_agent in an example: https://python.langchain.com/docs/integrations/tools/gmail/#use-within-an-agent

This issue doesn't need to be resolved by a single PR and can be tackled incrementally! Just tag this issue for tracking purposes :)

@efriis do you expect the changes in the documentation for the tools and integrations using `initialize_agent' listed at the bottom of the page you shared?

Such as:
AINetwork Toolkit

AWS Lambda

- Updated code to use `create_react_agent` instead of the deprecated `initialize_agent`.
- Removed explicit `AgentType` parameters as they are implicitly supported by `create_react_agent`.
- Replaced `verbose=True` with `debug=True` for detailed logging.

Partially addresses langchain-ai#29277

Hi everyone,

I’ve partially updated the documentation to replace deprecated references to initialize_agent with langgraph.prebuilt.create_react_agent. Specifically:

  • I addressed the instances for page 1 of 3 in the search:
    repo:langchain-ai/langchain path:/^docs\// initialize_agent.
  • I plan to work on pages 2 and 3 shortly to complete the updates.

Additionally, I noticed a recurring pattern in examples, such as:

agent.run("what is google's stock")

This doesn't inherently print the output of the agent.run command, and I considered adding something like:

response = agent.run("what is google's stock")
print(response)

to improve clarity for users. However, as this is my first commit, I didn’t want to overstep the scope without further guidance. Let me know if you’d like me to include such improvements!

Looking forward to completing the remaining pages soon.
