Thanks for the contribution. This PR has approval, but it cannot be merged while pre-check-plugin is failing. Please update the package so it follows the Dify plugin submission standards and the pre-check passes, then ping the maintainers to try the review/merge again.

[crazywoola]

Thanks for the update. The PR is approved, but pre-check-plugin is currently failing again, so we cannot merge it yet.

Could you please check the CI logs, fix the failing check, and push an update? Once CI is green again, we can take another look and proceed with merge if everything still looks good.
