We had a couple of other weird ideas that we discarded as they were not as intuitive. ie you could drag in files and tools along with the idea of what you want, and Marble would come up with 3 task cards for you to select from (we proactively included different files or tools that could complement your goal/request).

Another idea was a "preview" step before running a task, which used dummy data to mock up a visual of what the output from a task could look like. This allowed you to shape the structure of the task results before even running it. It ended up being confusing as it was hard to tell real vs fake/simulated dummy results.

Something we will be keeping, though, is the ability to have an artifact opened i.e., a spreadsheet, Slides, PDF... and select or interact with any part of the document, and Marble proactively suggests ways to extend that document with the context of what you selected/highlighted, and the purpose of the workspace/the work task. It will look like a tool selection wheel used in video games.
