Non precise error on save/build
When a build fails or save fails, the error prompt is not descriptive:
The attempted operation has returned an unspecified error. This may be due to an expired session, or a model that exceeds 1MB in size.
Think more descriptive and precises error messages are needed, algo between every save or build I usually make several changes, it would be nice so the difference between actual json and the one from the previous successful save.

You can fix this by erasing your browser history, cookies and your saved cache, then it should work again.
Provide more details when your skill simply stop building without any code change. Just saying my model could be over 1mb (when it is clearly not) does not help.
