Looks good to me if you implement a few changes:
1. Separate the first sentence of the documentation into a separate paragraph, as suggested in https://github.com/llvm/llvm-project/pull/175342/changes#discussion_r2776148654
2. Mention this check in the changelog (just before merging the PR).
3. Don't include sstream (marked in inline comment).
