Type declaration

  • Optional input?: string
verbose: boolean

Whether to print out response text.

callbacks?: Callbacks
metadata?: Record<string, unknown>
tags?: string[]

Methods

  • Calls the tool with the provided argument and callbacks. It handles string inputs specifically.

    Parameters

    • arg: undefined | string | {
          input?: string;
      }

      The input argument for the tool, which can be a string, undefined, or an input of the tool's schema.

    • Optional callbacks: Callbacks

      Optional callbacks for the tool.

    Returns Promise<string>

    A Promise that resolves with a string.

  • Fetches the content of a specific Wikipedia page. It returns the extracted content as a string.

    Parameters

    • page: string

      The specific Wikipedia page to fetch its content.

    • redirect: boolean = true

      A boolean value to indicate whether to redirect or not.

    Returns Promise<string>

    The extracted content of the specific Wikipedia page as a string.

  • Invokes the tool with the provided input and configuration.

    Parameters

    • input: string | {}

      The input for the tool.

    • Optional config: BaseCallbackConfig

      Optional configuration for the tool.

    Returns Promise<string>

    A Promise that resolves with a string.

  • Create a new runnable sequence that runs each individual runnable in series, piping the output of one runnable into another runnable or runnable-like.

    Type Parameters

    • NewRunOutput

    Parameters

    • coerceable: RunnableLike<string, NewRunOutput>

      A runnable, function, or object whose values are functions or runnables.

    Returns RunnableSequence<string | {}, Exclude<NewRunOutput, Error>>

    A new runnable sequence.

  • Stream all output from a runnable, as reported to the callback system. This includes all inner runs of LLMs, Retrievers, Tools, etc. Output is streamed as Log objects, which include a list of jsonpatch ops that describe how the state of the run has changed in each step, and the final state of the run. The jsonpatch ops can be applied in order to construct state.

    Parameters

    • input: string | {}
    • Optional options: Partial<BaseCallbackConfig>
    • Optional streamOptions: Omit<LogStreamCallbackHandlerInput, "autoClose">

    Returns AsyncGenerator<RunLogPatch, any, unknown>

  • Default implementation of transform, which buffers input and then calls stream. Subclasses should override this method if they can start producing output while input is still being generated.

    Parameters

    • generator: AsyncGenerator<string | {}, any, unknown>
    • options: Partial<BaseCallbackConfig>

    Returns AsyncGenerator<string, any, unknown>

  • Builds a URL for the Wikipedia API using the provided parameters.

    Type Parameters

    • P extends UrlParameters

    Parameters

    • parameters: P

      The parameters to be used in building the URL.

    Returns string

    A string representing the built URL.
