Hi all - bit of an edge case here, but seemed worth reporting.
In this repository's ruleset, the 'color-function-notation' rule is set to 'modern' (inherited from here )
However, this modifies code like rgb(black, 0.5); to rgb(black 0.5); - causing compilation errors, as SASS supports the format rgb($color, $alpha) but not rgb($color $alpha)
