Hey @Noai-oss - this actually looks good! I see that this is a draft - what is missing from the implementation?

Hi, apologies for the delayed PR update.
Since the last revision, I removed the attribute parameter and now access .version directly. I also replaced the previous heuristic version-detection logic with an explicit prefix parameter to reduce ambiguity, which was one of my concerns with the earlier implementation.
I’ve pushed these changes and marked the PR as ready for review. Thank you for your patience.

LGTM, thanks!!!
