I made one, called Claudine:

https://github.com/xemantic/claudine

You can prompt it like: "I want you to act as a software developer. I will give you a source code repository of a project. Clone it. Pick up an issue to fix from project's GitHub issues and implement the fix. Here is the repo: git@github.com:processing/p5.js.git

Thanks for making me aware of your project! I have added Claudine to the README under "related projects".
