cfgov-refresh has the following URL in the readme that populates a new bug report with filled in values:

The URL looks like:
https://github.com/cfpb/cfgov-refresh/issues/new?body=%23%23%20URL%0D%0D%0D%23%23%20Actual%20Behavior%0D%0D%0D%23%23%20Expected%20Behavior%0D%0D%0D%23%23%20Steps%20to%20Reproduce%0D%0D%0D%23%23%20Screenshot&labels=bug

A generic template for a URL like this might be nice to include in this repo's example project Readme. It could be copied-and-pasted and with filler for the project... e.g.:

https://github.com/cfpb/<REPLACE WITH PROJECT REPOSITORY NAME>/issues/new?body=%23%23%20Actual%20Behavior%0D%0D%0D%23%23%20Expected%20Behavior%0D%0D%0D%23%23%20Steps%20to%20Reproduce%0D%0D%0D%23%23%20Screenshot&labels=bug
