Feature request

Include support for tools for Anthropic Claude models.
I suggest a similar approach as done for OpenAI GPT, so that the creation of a function named create_anthropic_tools_agent(...) and a class OpenAIToolsAgentOutputParser(...).

Motivation

Last week Anthropic announced the support of tools in Claude models.
Langchain already supports OpenAI tools agents for GPT models through function create_openai_tools_agent(...) and a specialized parser class OpenAIToolsAgentOutputParser

The community has a huge interest in seeing langchain supporting all models, specially the most popular, strongest, and cheapest models.

Proposal (If applicable)

I could take this PR, if core maintainers agree and find this idea useful.

[rafaelpadilla]

With the latest updates and creation of the create_tool_calling_agent(), this feature has been already implemented.

Now it's possible to use tools with Anthropic models.

So, I'm closing this discussion for now.
