Building @Tonkotsu has taught us many lessons in product design, with both the underlying technology and user behavior shifting rapidly.

One of the hardest but most critical lessons we ve learned is about calibrating the zoom level how close or far the user feels from the work. You can see examples of this play out across the industry:

• Codex gets flak for going heads-down for too long compared to Claude. Users feel too zoomed out from the work.

• By contrast, Cursor and IDEs are starting to feel too zoomed in. When the majority of code is written by agents, an editor-first UI is a misfit.
