The changes look good overall, with some minor suggestions for improvement. Here's my review:

Positive Aspects:

1. Variable descriptions are more concise and clearer
2. Consistent formatting throughout both files
3. Maintains all existing functionality while improving documentation

Suggestions for Improvement:

1. In variables.tf, consider adding validation for iam_role_policy_arns to ensure ARN format validity
2. Some descriptions could still be slightly more specific:

   # For tags variable, perhaps:
   description = "Tags to apply to all created resources"
   
   # For url variable:
   description = "OIDC identity provider URL"

Minor Issues:

1. In TERRAFORM.md, there's an inconsistent slash after <pre> in the gitlab_repositories type definition
2. Consider adding units to default values in descriptions where applicable (e.g., "3600s" for max_session_duration)

Overall, this is a good improvement to the documentation and variable descriptions, making the module more maintainable and easier to understand.
