I think a better example is how Marble makes tools visible and easy to select for each task instead of requiring you to remember what exists or describing everything through the prompt.

Marble keeps the tools you use most close at hand and will surface other useful ones for the job. Combined with a birds eye view of multiple tasks running, it makes agent work easier to set up and manage. The goal is to minimize cognitive overhead in day to day tasks (both in specifying what you want, and managing after you ran something)
