Hey Benedict, I agree with Calvin's idea. We should better run check in CI and hint user how to add license. But I think if we want to achieve this function. We should a bot and use commands to trigger whether to automatically modify files or not.
I give a simple example here. when bot hint license or header is missing, and we think it just add some header to it. we should trigger by simple command in github like `/auto-license` and bot would auto add license header to missing file. **BUT I think maybe this is too COMPLEX for now** But if we think we could implement it in a short time, it would be great. Otherwise, Benedict idea is OK to me, it use wish to use our dev script to auto full license or header, he/she should install python develop envirement locally. Or use could fix license issue manually Cheers, — Jiajie Zhong
