Original GitHub issue: https://github.com/langchain-ai/deepagentsjs/issues/14

Background

The current implementation of writeTodos tool:

export const writeTodos = tool(
  (input, config: ToolRunnableConfig) => {
    return {
      update: {
        todos: input.todos,
        messages: [
          new ToolMessage({
            content: `Updated todo list to ${JSON.stringify(input.todos)}`,
            tool_call_id: config.toolCall?.id as string,
          }),
        ],
      },
    };
  },
  { /* ... */ }
);
  • The state seems to be updated correctly 🤔.
  • The tool function dose not return a command object.
  • This is not in the official doc.

Question

  • Is this a valid shorthand or it is recommanded to have the command object plz?

The expected way (AFAIK):

// …inside your tool function:
return new Command({
  update: {
    todos: input.todos,
    messages: [
      new ToolMessage({
        content: `Updated todo list to ${JSON.stringify(input.todos)}`,
        tool_call_id: config.toolCall?.id as string,
      }),
    ],
  },
});
