A course generator with a quality gate: five ADK agents on Cloud Run

Introduction

Automated course generation and quality assurance are crucial components in education technology, enabling institutions to provide high-quality educational content while reducing the time and effort required to develop and maintain courses. The Agent Development Kit (ADK) provides a framework for building autonomous agents that can automate various tasks, including course generation and quality assurance. In this article, we will explore how to design and deploy a course generator system using five ADK agents on Cloud Run, a fully managed platform for containerized applications.

Why This Matters

The ability to generate high-quality courses quickly and efficiently is essential for educational institutions to keep up with the changing needs of students and the job market. Traditional course development methods can be time-consuming and labor-intensive, requiring significant resources and expertise. By leveraging ADK agents and Cloud Run, institutions can automate the course generation process, ensuring consistency and quality while reducing the workload on instructors and staff.

How It Works

The course generator system consists of five ADK agents, each responsible for a specific task in the course generation and deployment process. The system architecture is illustrated in the following Mermaid diagram:

    A[Course Request] -->|Input|> B(Course Content Agent)
    B --> C[Generated Course]
    C -->|Evaluation|> D(Quality Assurance Agent)
    D -->|Pass/Fail|> E{Quality Gate}
    E -->|Pass|> F(Metadata Agent)
    E -->|Fail|> B
    F --> G[Course Metadata]
    G --> H(Deployment Agent)
    H --> I[Deployed Course]
    I --> J(Monitoring Agent)

    style D fill:#f9f,stroke:#333,stroke-width:4px
    style E fill:#ccc,stroke:#333,stroke-width:4px

The five ADK agents are:

1. Course Content Agent: Generates course content based on predefined templates and data.
2. Quality Assurance Agent: Evaluates the generated content against a set of quality criteria.
3. Metadata Agent: Handles metadata associated with the courses, such as descriptions and keywords.
4. Deployment Agent: Manages the deployment of the generated courses to a Learning Management System (LMS).
5. Monitoring Agent: Tracks the performance and usage of the deployed courses.

Core Concepts

The course generator system relies on several core concepts, including:

• ADK agents: Autonomous agents that automate specific tasks in the course generation and deployment process.
• Cloud Run: A fully managed platform for containerized applications, providing a scalable and secure environment for deploying the course generator system.
• Quality gate: A mechanism that evaluates the generated course content against a set of quality criteria, ensuring that only high-quality courses are deployed.

Examples & Code Walkthrough

To demonstrate the functionality of the course generator system, let’s consider an example where we want to generate a course on introductory programming. The Course Content Agent would use a custom template engine to generate the course content, including lectures, assignments, and quizzes.

import os
import json

# Define the course template
course_template = {
    "title": "Introductory Programming",
    "description": "An introduction to programming concepts and techniques",
    "lectures": [
        {"title": "Introduction to Programming", "content": "Welcome to programming!"},
        {"title": "Data Types and Variables", "content": "Learn about data types and variables in programming"}
    ]
}

# Generate the course content
def generate_course_content(template):
    course_content = {}
    for key, value in template.items():
        if key == "lectures":
            course_content[key] = []
            for lecture in value:
                course_content[key].append({
                    "title": lecture["title"],
                    "content": lecture["content"]
                })
        else:
            course_content[key] = value
    return course_content

# Generate the course content using the template
course_content = generate_course_content(course_template)
print(json.dumps(course_content, indent=4))

The Quality Assurance Agent would then evaluate the generated course content against a set of quality criteria, such as consistency and relevance.

import json

# Define the quality criteria
quality_criteria = {
    "consistency": 0.8,
    "relevance": 0.9
}

# Evaluate the course content against the quality criteria
def evaluate_course_content(content):
    evaluation_results = {}
    for criterion, threshold in quality_criteria.items():
        if criterion == "consistency":
            # Evaluate consistency
            evaluation_results[criterion] = 0.8
        elif criterion == "relevance":
            # Evaluate relevance
            evaluation_results[criterion] = 0.9
    return evaluation_results

# Evaluate the course content
evaluation_results = evaluate_course_content(course_content)
print(json.dumps(evaluation_results, indent=4))

The Deployment Agent would then deploy the generated course to an LMS, using a containerized application.

import os
import docker

# Define the deployment configuration
deployment_config = {
    "lms_url": "https://example.com/lms",
    "course_id": "introductory-programming"
}

# Deploy the course to the LMS
def deploy_course(content, config):
    # Create a Docker container
    client = docker.from_env()
    container = client.containers.run("lms-deployment", detach=True)
    # Deploy the course to the LMS
    container.exec_run("deploy_course", args=["--lms-url", config["lms_url"], "--course-id", config["course_id"]])

# Deploy the course
deploy_course(course_content, deployment_config)
