I think @fhanau approval on this is a condition for merging

See internal PR 8342 for some prior work on enabling buildifier automatically on the downstream repo – I was planning to patch up that PR today but looks like you got here first. It uses a different approach to downloading buildifier that I think is preferable, but I'll have to incorporate Dan's suggestions on how to invoke it – will provide some detailed notes on that later today and review this.

Seems to me like we mind as well land this change as is and you can convert the installation method in a separate PR later.

Dependant on @fhanau approval of bazel file changes.

[fhanau]

This also applies for the other linters we added be we should document that buildifier needs to be installed as running the formatter is now a key part of development, even if invoked indirectly.

[fhanau]

LGTM except for this not being documented, but that goes for the other linters too.

I added a new issue to document the linters: #2581
