🚀 Getting Started

pip install -r requirements.txt

✨ Example

Git Diff

diff --git a/src/utils.py b/src/utils.py index 1a2b3c4..5d6ef7f 100644 --- a/src/utils.py +++ b/src/utils.py @@ def calculate_average(numbers): - return sum(numbers) / len(numbers) + if not numbers: + return 0 + return sum(numbers) / len(numbers) @@ def greet_user(name): - print("Hello", name) + print(f"Hello, {name} 👋")

Output PR Description

**Title:** [Utils] Handle empty list in average calculation and improved greeting **Description:** - Added edge case handling for `calculate_average()` to return 0 when given an empty list. - Enhanced user experience by adding an emoji in the greeting function `greet_user()`. These changes improve error handling and make output more user-friendly.

🧠 How it Works

The Gradio UI sends the pasted diff to http://localhost:8000/mistral
FastAPI receives it and forms a prompt for the local Mistral model
Mistral responds with a human-readable PR title + description
The Gradio UI displays the result

🔒 Privacy Note

This tool is completely local. Nothing is sent to the cloud — your code and git diffs stay on your machine.
