@loopstack/custom-tool-example-module

A module for the Loopstack AI automation framework.

This module provides a complete example demonstrating how to implement and use custom tools in a Loopstack workflow.

Overview

Custom tools are the building blocks of Loopstack automations. This module serves as a hands-on reference for developers learning how to extend Loopstack with their own functionality.

By exploring this example, you'll understand:

• How to create tools that perform specific tasks within workflows
• The difference between stateless and stateful tools
• How to use dependency injection to keep tools modular and testable
• How to wire tools into workflows using YAML configuration
• How to structure and export a reusable module

This is a great starting point before building your own custom tools.

Installation

Prerequisites

Create a new Loopstack project if you haven't already:

npx create-loopstack-app my-project
cd my-project

Start Environment

cd my-project
docker compose up -d

Add the Module

loopstack add @loopstack/custom-tool-example-module

This copies the source files into your src directory.

Using the loopstack add command is a great way to explore the code to learn new concepts or add own customizations.

Setup

1. Import the Module

Add CustomToolModule to your default.module.ts (included in the skeleton app) or to your own module:

import { Module } from '@nestjs/common';
import { LoopCoreModule } from '@loopstack/core';
import { DefaultWorkspace } from './default.workspace';
import { CustomToolModule } from './custom-tool-example-module';

@Module({
  imports: [LoopCoreModule, CustomToolModule],
  providers: [DefaultWorkspace],
})
export class DefaultModule {}

2. Register the Workflow

Add the workflow to your default.workspace.ts or your own workspace:

import { WorkspaceBase } from '@loopstack/core';
import { Injectable } from '@nestjs/common';
import { BlockConfig, Workflow } from '@loopstack/common';
import { CustomToolExampleWorkflow } from './custom-tool-example-module/workflows';

@Injectable()
@BlockConfig({
  config: {
    title: 'Default Workspace',
  },
})
export class DefaultWorkspace extends WorkspaceBase {
  @Workflow() customToolExample: CustomToolExampleWorkflow;
}

3. Run Backend

npm run start:dev

Open localhost:3000 and execute the workflow in the Loopstack Studio.
