🤔 What is LLM-Contract?

Imagine you have a super-smart AI assistant that helps you write emails, summarize documents, or answer questions. How do you know it will always work correctly? How do you know it won't suddenly start giving wrong answers after you make a small change?

That's what LLM-Contract is for. It's a special tool that helps you test and check your AI, just like a quality check in a factory. You can tell it what the AI should do, and LLM-Contract will run checks to see if it meets your expectations. It's like a safety net for your AI!

This tool is built for developers, so it lets them use it from a simple command prompt on their computer (Windows, Mac, or Linux). It also comes as a ready-to-use library that can be added to existing software projects built with TypeScript.

💡 Why Do You Need It?

AI is powerful, but it's not always predictable. LLM-Contract helps you answer critical questions:

Did my change break something? After tweaking your AI's instructions, you can run checks to see if it still behaves as expected.
Is my AI giving the right format? If you need it to return a specific structure (like a table or a list), you can validate that.
Is my AI 'grounded' in facts? For AI that answers questions based on a set of documents (RAG), it checks if the answers are actually based on the provided material.
Is the AI flaky? It can sometimes pass a test and sometimes fail not because of you, but because the AI is a bit unpredictable. LLM-Contract helps track and identify these flaky results.
Does it pass my quality gate? It integrates into your software-building pipeline (CI/CD), so if the tests fail, the next version won't be released. Safety first!

🚀 Key Features That Help You

🧪 Test Your AI Agents

Define a "contract" of expected behaviors for your AI assistant. Whether it's a simple chatbot or a complex agent that uses tools, you can specify what "good" looks like, and LLM-Contract will check.

🔄 Catch Regressions Early

Made a change to your AI's prompt? Run the suite to see if it still follows the original rules. Catch mistakes before your users do.

📐 Validate Structured Output

If your AI should return data in a specific format (like JSON for a program to read), LLM-Contract can verify the structure is perfect every time.

📚 RAG Grounding Check

For systems that use Retrieval-Augmented Generation (RAG), ensure the AI only uses your provided information and doesn't make things up.

📈 Track Flakiness

AI can be unpredictable. LLM-Contract helps you separate real problems from random failures, giving you a clearer picture of your system's reliability.

⚙️ CI/CD Ready

Easily plug it into your automated software delivery pipeline. Set it as a gate to prevent releases when your AI fails the checks.

Operating System: Windows 10 or later, macOS 12 or later, or a modern Linux distribution (like Ubuntu 20.04 or later).
Memory: At least 4 GB of RAM is recommended for smooth testing, especially for larger AI models.
Storage: About 500 MB of free disk space for the tool and its dependencies.
Internet Connection: An active internet connection is required to interact with most large language models (like GPT-4, Claude, etc.) that you will be testing.
Optional: Node.js (version 18 or higher) if you plan to use it as a library within your own software projects.

🚦 Your First Steps

After you've downloaded the application, here’s a non-technical overview of what to expect. Detailed instructions will be in the documentation you get with the download.

Find the files: Once you download and extract the package (if it's a zip file), you'll see an executable file or a way to install it.
Open your command line: On Windows, you can search for "Command Prompt" or "PowerShell". On Mac, search for "Terminal".
Run the tool: You'll type a simple command to start LLM-Contract. It will guide you through setting up your first test.
Configure your AI: You tell it which AI model to talk to (using your API key) and what behavior to expect.
Run your tests: It will then perform the checks and show you a clear report—pass or fail—right in your command window.

Remember: The download page will include full, step-by-step instructions tailored to the specific version you get. It's simpler than it sounds!
