Probably worth updating this reference in TESTING.rst as well.

static checks are failing with following message Skipping breeze pre-commit as SKIP_BREEZE_PRE_COMMIT is set. However it works fine when I run the breeze static-checks --only-my-changes and the Update output of breeze commands in BREEZE.rst check passed. Any idea why this check fails?

This code is wrong likely - it should be exit(0)

   if os.environ.get("SKIP_BREEZE_PRE_COMMITS"):
        console.print("[yellow]Skipping breeze pre-commit as SKIP_BREEZE_PRE_COMMIT is set")
        sys.exit(1)
