If you’re an AI developer looking to hone your skills, building AI agents it is one of the most effective ways to gain experience. AI agents represent effective applications of AI in all domains, from personal assistants and recommendation systems to financial traders.
Here we are 10 AI agents every engineer must build. For each, you will receive a GitHub link which provides a sample implementation, so you can reference or extend the code into your own version.
1. Recommendation Agent
Recommendation agents help personalize the user experience by recommending products, content, or services. They are often used in e-commerce, broadcast media, and social media.
Skills you will learn to build this agent:
- Collaborative sorting
- Content-based filtering
- Reinforcement learning for praise
GitHub sample: Microsoft recommendations
This repo provides a complete set of tools to build and test recommendation systems.
2. Code agent
The code agent automatically navigates and resolves issues within code collections. It can suggest fixes, automatically organize files, and run tests to make sure everything is working as expected.
Skills you will learn to build this agent:
- Code navigation and analysis
- Automated testing
- Problem solving using AI
GitHub sample: swe-agent
This repo shows how an AI agent can help navigate repositories, identify coding problems, and transform the debugging process.
3. AI Research Agent
AI research agents are designed to conduct web-based research, collect relevant papers, and compile findings into reports. These agents help you understand how AI can be used in scientific experiments and data collection.
Skills you will learn to build this agent:
- Web scraping
- Document analysis
- Data summary
- Long form content production
GitHub sample: gpt-researcher
This repo shows how to build an AI agent that performs research tasks, collects data, and generates a detailed research report.
4. Browser automation agent
A browser automation agent interacts with websites to perform tasks such as filling out forms, automating clicks, or scraping data. This project teaches you how to programmatically control the browser.
Skills you will learn to build this agent:
- Web automation
- Performance of work
- Form management
GitHub sample: browser usage
Here’s an automated tool that manages browser-based tasks, such as filling out forms or clicking features within web applications.
5. Q&A Document / RAG Agent
A Retrieval-Augmented Generation (RAG) agent allows users to ask questions related to documents and get grounded answers by finding relevant content and summarizing it. Perfect for building informational assistants or support bots.
Skills you will learn to build this agent:
- Document analysis
- Embedding-based retrieval
- Generating a reasoned response
GitHub sample: RAG-Anything
This chapter walks you through building an agent that can retrieve data from documents and generate relevant responses based on user queries.
6. Customer Support Agent
Customer support agents handle inquiries and resolve user issues. This agent can integrate with chat systems and resolve customer queries using pre-defined flows or AI-generated responses.
Skills you will learn to build this agent:
- AI discussion
- Objective recognition
- Content management
GitHub sample: Help desk assistant
Rasa’s open source chat AI can be used as a blueprint for creating intelligent customer support agents that can handle various customer queries.
7. Personal AI Assistant Agent
A personal assistant helps manage tasks, answer questions, and integrate with APIs like weather, calendar, or reminders. It’s a hands-on experience learning to interact with APIs, handle natural language input, and build voice assistants.
Skills you will learn to build this agent:
- NLP (Natural Language Processing)
- Speech recognition
- API integration
- Real-time processing
GitHub sample: QwenPaw Personal Assistant
This repo gives you a real foundation for building your own assistant using voice and text input. It integrates APIs and handles various user commands.
8. Predictive Maintenance Agent
Predictive maintenance agents analyze sensor data to predict when machines or equipment will fail. This type of agent is important in industries such as manufacturing, where minimizing downtime is important.
Skills you will learn to build this agent:
- Time series forecasting
- A mysterious discovery
- Predictive statistics
GitHub sample: Predictive Maintenance Using Machine Learning
This room uses machine learning to predict maintenance needs by analyzing sensor data and identifying anomalies.
9. Computer Vision Agent
Computer vision agents can process images to identify objects, recognize faces, or perform other image-based tasks. This agent will help you explore convolutional neural networks (CNNs) and object detection.
Skills you will learn to build this agent:
- Image segmentation
- Object discovery
- Real time description
GitHub sample: YOLOv5 by Ultralytics
A state-of-the-art database for real-time object discovery using YOLOv5. This repo includes sample training and reference code that you can extend to your own vision projects.
10. Financial Trading Agent
A financial trading agent uses historical market data and reinforcement learning to predict stock prices and trade. This agent can help you understand how AI is used in financial markets.
Skills you will learn to build this agent:
- Reinforcement teaching
- Time series forecasting
- Market simulation and regression
GitHub sample: FinRL trading
FinRL provides a framework for building, training, and evaluating commercial agents for reinforcement learning.
Where will you start?
The best way to build is to choose one AI agent that matches your current skill level and learning goal.
If you’re new to AI agents, start with AI personal assistant or Q&A/RAG Document Agent. These projects will help you understand data, APIs, retrieval, and underlying responses without feeling overwhelmed. Once you are comfortable, move on to more advanced projects such as coding agents, computer vision agents, or financial trading agents.
By building these AI agents, you’ll gain real-world AI engineering experience, strengthen your portfolio, and build confidence in designing AI systems that solve logical problems.
