I'm interested to try out Gitmate, and I've requested the permission for it to be installed in Python GitHub organization. https://gitmate.io/ Several of its features I'd like to try out for now: - automatically add size labels on pull requests. It can analyze the content of the pull request, and apply the size labels (xs, s, m, etc) - apply stale label for inactive pull requsts gitmate has been used by coala. Here is an example of a PR where it automatically add stale, size labels, and also checks of PEP 8 compliance: https://github.com/coala/coala/pull/4818 I find the code analysis feature of gitmate (checking for PEP 8 etc) is too noisy, so I don't think we should add it now. If it works for the devguide or core workflow, perhaps later we can try adding this to cpython too? Mariatta
