I personally would like to see this as well.
To me it makes sense to have a form for name, description, and activation words and which words to turn to vars. (Optional settings page, for user defined settings)
List of actions(that could be filtered by model, apis, etc), ability to chain actions and redirect outputs or stop to ask for more input(which is really just another action).
Generates python code, that could be downloaded or uploaded to github or installed to your mycroft via the home.mycroft.ai page.
Requiring much more than to make a skill feels like a hindrance to me ( I am very lazy )
I havn’t looked over this project yet, but they have allot built up so far, so I figure I would post it. https://github.com/augustnmonteiro/mycroft-skills-visual-programming
I started one too, for a more basic webpage type. With the idea that it would be intergrated into an existing page (but could be ran from home as well).
This thread Servo for Visual Skill Building and Conversational Interaction mention https://github.com/servo-ai/servo-platform as an option too.
I would think using the msk https://mycroft.ai/documentation/skills/msk/ for the back end makes sense. It seems (from the docs) limited to the comment boiler plate and creating utterace testing currently.
