Hey, yes, it's a custom extension that was made for me, at least for now it's just customisation around a few open source extensions.
As luceos said I recommend you to use the services tag or if it's urgent contact directly with some developers to find out mainly the availability they have.
Abdel yes exactly also a summerie data like 200 caractere also need to be there as well
That in particular is Synopsis (https://github.com/imorland/synopsis), a few months ago I sponsored the feature to add different lengths depending on the tag so you can play around with it.
