shouldRetryOnFailure: boolean

Whether the tool execution should be retried on failure

maxRetryAttempts

maxRetryAttempts: number

Maximum retry attempts

baseRetryDelay

baseRetryDelay: number = 1000

Methods

validateArguments

processLlmRequest

  • processLlmRequest(_toolContext, llmRequest): Promise<void>

  • Processes the outgoing LLM request for this tool.

    Use cases:

    • Most common use case is adding this tool to the LLM request.
    • Some tools may just preprocess the LLM request before it's sent out.

    Parameters

    Returns Promise<void>

safeExecute

getDeclaration

  • getDeclaration(): FunctionDeclaration

  • Gets the OpenAPI specification of this tool in the form of a FunctionDeclaration

    NOTE:

    • Required if subclass uses the default implementation of processLlmRequest to add function declaration to LLM request.
    • Otherwise, can return null, e.g. for a built-in GoogleSearch tool.

    Returns FunctionDeclaration

    The FunctionDeclaration of this tool, or null if it doesn't need to be added to LlmRequest.config.

runAsync

  • runAsync(args, _context): Promise<GlobToolResult>

  • Runs the tool with the given arguments and context

    NOTE:

    • Required if this tool needs to run at the client side.
    • Otherwise, can be skipped, e.g. for a built-in GoogleSearch tool.

    Parameters

    • args: {
          pattern: string;
      }

      The LLM-filled arguments

      • pattern: string
    • _context: ToolContext

    Returns Promise<GlobToolResult>

    The result of running the tool
