Would it be possible to add some kind of message why compiling failed? I suppose that it can be difficult to recognize the reason for test failure without a message. Especially when you are new to a project or external contributor

I had it on my mind, but I decided to leave it with default formatting error that scarb displays (same when compilation fails due to any error, we don't handle it in script). Wdyt @kkawula ? Don't have a strong opinion though.

Hmm, I suppose that it will be helpful to at least add info about start of format checking, because at first look I don't know why this compilation failed gh job. Some kind of Checking contracts formatting message
