Right now, AFAIK there is no API to read or write to blueprint descriptions.

I have a mod which deals with creating blueprints; it would be nice if I would allow users to save/write to descriptions, but this is currently not (reasonably) possible to do.

I use his mod (https://mods.factorio.com/mod/bp100) a lot and I would like to add my support for this request. Right now I have to manually copy the description over to the blueprints created in Staged Blueprint Planning whenever I modify any of the blueprints that have descriptions. Enabling the mod to have access to the blueprint description would simplify this process and make the mod that much more versatile

We also really want this.

A workaround with edge case issues is to export to a blueprint string, decode the JSON, modify the JSON, and import it back. I'm blind and working "in the backend" if you will by the nature of mods but I believe the edge case is that if the blueprint is in hand then the rotation resets. Not 100% sure. I do know that another edge case of a blueprint in hand is that cursor_stack_temporary resets.

Would really appreciate some love from the devs on this. I'm stuck on building a blueprint repo and build system because of this. There seems to be no way to read/write blueprint/book descriptions still, and no way to detect when the user edits them.
I've described my issue in another post here:

OK. I've added it for the next release.

Oh! Incredible! Excited to be able to release this tool for all the factorio blueprinters out there.
