Give your python scripts regenerative healing abilities!

Run your scripts with Wolverine and when they crash, GPT-4 edits them and explains what went wrong. Even if you have many bugs it will repeatedly rerun until it's fixed.

For a quick demonstration see my demo video on twitter.

python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
cp .env.sample .env

Add your openAI api key to .env

warning! By default wolverine uses GPT-4 and may make many repeated calls to the api.

To run with gpt-4 (the default, tested option):

python wolverine.py buggy_script.py "subtract" 20 3

You can also run with other models, but be warned they may not adhere to the edit format as well:

python wolverine.py --model=gpt-3.5-turbo buggy_script.py "subtract" 20 3

If you want to use GPT-3.5 by default instead of GPT-4 uncomment the default model line in .env:

DEFAULT_MODEL=gpt-3.5-turbo

You can also use flag --confirm=True which will ask you yes or no before making changes to the file. If flag is not used then it will apply the changes to the file

python wolverine.py buggy_script.py "subtract" 20 3 --confirm=True

This is just a quick prototype I threw together in a few hours. There are many possible extensions and contributions are welcome:

• add flags to customize usage, such as asking for user confirmation before running changed code
• further iterations on the edit format that GPT responds in. Currently it struggles a bit with indentation, but I'm sure that can be improved
• a suite of example buggy files that we can test prompts on to ensure reliability and measure improvement
• multiple files / codebases: send GPT everything that appears in the stacktrace
• graceful handling of large files - should we just send GPT relevant classes / functions?
• extension to languages other than python
