Hi @tstellar . The workflow I am trying to add takes around 5 minutes to run (with almost all of that being the checkout action). I created the workflow following a request by @compnerd and @vgvassilev in order to allow the work for the following issue to progress https://github.com/llvm/llvm-project/issues/109483 . Sorry for the large number of failed commits to try and get it to run. I'm trying to work out the exact idt command which should be run.  Based on the test case added to ids here https://github.com/compnerd/ids/pull/34, I feel I should have got the right command, but for some reason it doesn't work in the workflow.
