ActiveRecord level tools

[pedrofs]

Is your feature request related to a problem? Please describe.
I want to have ActiveRecord as a tool.

Imagine I have a Workflow with a sequence of Action. Workflows have name and description. I would like to have each workflow record as a possible tool to be called.

Right now, this line https://github.com/patterns-ai-core/langchainrb/blob/main/lib/langchain/assistant.rb#L359 relies directly on the class of the tool so that I can't have this record-level dynamism.

Describe the solution you'd like
We could keep the DSL approach and have a tool_name method, which could receive an arbitrary string or a block with the tool as an argument and then have this record-level dynamism.

Describe alternatives you've considered
I'm currently defining a class in run-time:

def to_langchain_tool
  workflow = self
  class_name = "WORKFLOW_#{workflow.id}"

  Object.send(:remove_const, class_name) if Object.const_defined?(class_name)

  Object.const_set(class_name, Class.new do
    extend Langchain::ToolDefinition

    define_singleton_method :name do
      class_name
    end

    define_function :call, description: workflow.description

    def initialize(triggerable)
      @triggerable = triggerable
    end

    define_method :call do
      workflow.call(@triggerable)
    end
  end)
end

Maybe I'm not seeing something? Is there an easier way of accomplishing that?
