This metric measures the (absolute) number of comment lines per file. Whilst this is not especially meaningful out of context a low number of comments may indicate files that are difficult to understand due to poor documentation.

Recommendation¶

Consider if the file needs more documentation. Short files might not but most files should have at least a comment explaining their purpose.
