📚 What You Get

This vault gives you a clear path through the parts of AI engineering that matter most:

• 12 chapters on core AI system design
• 50+ patterns for real-world app building
• Guidance on RAG for knowledge-based answers
• Steps for agents that use tools and make decisions
• Notes on MCP for connecting systems
• Methods for evals so you can test output quality
• Help with token economics so you can manage cost
• Advice on vector search and retrieval
• Plain guidance for building with open-source tools

🧭 Main Sections

1. RAG Basics

Learn how to feed your app the right source content before it answers. This section covers document intake, chunking, retrieval, and answer flow.

2. Agent Design

See how agents work, when to use them, and where they fail. This section helps you decide if your app needs an agent or a simpler setup.

3. MCP Connections

Use MCP to connect tools and data sources in a clean way. This helps your app talk to other systems without hard wiring every link.

4. Evals and Checks

Test output quality before users see bad results. This section covers scorecards, test sets, and human review.

5. Token Cost Control

Learn how prompts, context size, and retrieval affect cost. This section helps you keep usage under control.

6. System Design

Get a view of how to shape AI apps so they stay stable as they grow. This includes data flow, error paths, and model choice.

🖱️ How to Use the App

1. Open ai-engineer-vault
2. Pick the chapter you want to read
3. Move through the sections in order if you are new to AI apps
4. Jump to a topic if you need help with one area
5. Use the patterns as a guide when you plan your own project

If you want the fastest path, start with:

• RAG
• Agents
• Evals
• Token cost
• MCP

🔍 Who This Is For

This app fits:

• founders working on AI products
• product teams planning LLM features
• engineers who want a shared playbook
• technical readers learning AI system design
• teams that need a vendor-neutral reference

It is also useful if you want a steady way to compare design choices before you build.

🧩 Common Use Cases

• plan a chatbot with document search
• design an agent that can use tools
• set up tests for AI output
• reduce token spend
• pick a retrieval method for internal docs
• decide when to use RAG instead of fine-tuning
• compare model and database choices
• map a safe path from prototype to production

⚙️ File Layout

After you open the downloaded content, you may see folders like these:

• chapters/ for the main reading material
• patterns/ for reusable design ideas
• examples/ for sample setups
• assets/ for images and diagrams
• docs/ for support material

If the download gives you a single app file, you do not need to change anything inside it.

📌 Best Way to Read It

Start with the early chapters first. They give you the base terms and common system shapes. Then move to the later chapters for deeper topics like evals, agents, and cost control.

A simple reading path:

1. Read the RAG chapter
2. Read the agent chapter
3. Read the eval chapter
4. Read the token economics chapter
5. Read the MCP chapter
6. Review the patterns section for design help

🧪 Simple Checks If It Does Not Open

• Make sure the download finished
• Try opening it again from the Downloads folder
• Right-click the file and choose Run as administrator
• Check that Windows did not move the file to quarantine
• Re-download the file if it looks damaged
• Try a different browser if the download fails

🔐 Safety and Privacy

This project is meant for reading and learning. Keep your browser and Windows updates current. If you use your own AI tools with this material, review any data you send to outside services.
