BaseMultiActionAgent is not exported by "langchain/agents"

[msalafia]

As the title suggest, i was trying to import BaseMultiActionAgent but it seems like it's not exported

const { BaseMultiActionAgent } = require("langchain/agents");

Is any reason for that, or it's just an error?

Hello @msalafia! I'm Dosu, a friendly bot created to assist you with bugs, answer your questions, and guide you on your journey to becoming a contributor. While we wait for a human maintainer, I'm here to help! Let's get started.

Based on the provided context, it appears that the BaseMultiActionAgent class is indeed defined in the "langchain/agents" module of the langchainjs codebase, but it's not included in the export statements. This means that it's not available for import in other modules.

The decision to export a class or not usually depends on whether it's intended to be used directly by users of the library or if it's just an internal detail of the library. If BaseMultiActionAgent is not exported, it might be because it's intended to be used only as a base class within the library itself, and not directly by users of the library.

If you believe that BaseMultiActionAgent should be exported, I would recommend reaching out to the maintainers of the langchainjs repository directly to discuss this. They may have chosen not to export this class for a specific reason.

Here is the relevant code snippet from the provided context:

/**
 * Abstract base class for multi-action agents in LangChain. Extends the
 * BaseAgent class and provides additional functionality specific to
 * multi-action agents.
 */
export abstract class BaseMultiActionAgent extends BaseAgent {
  _agentActionType(): string {
    return "multi" as const;
  }
/**
   * Decide what to do, given some input.
   *
   * @param steps - Steps the LLM has taken so far, along with observations from each.
   * @param inputs - User inputs.
   * @param callbackManager - Callback manager.
   *
   * @returns Actions specifying what tools to use.
   */
  abstract plan(
    steps: AgentStep[],
    inputs: ChainValues,
    callbackManager?: CallbackManager
  ): Promise<AgentAction[] | AgentFinish>;
}

You can find this code in the langchain/src/agents/agent.ts file of the langchainjs repository.

I hope this helps! If you have any other questions, feel free to ask.
