MarbleOS

Drive an agent through a chat window long enough and you lose track of the file it made three messages ago. MarbleOS answers that by laying the workspace out instead of burying it in a transcript: files, tools, tasks, and outputs each get a visible place. File management, task tracking, and tool integration live in one environment rather than scattering across a conversation and whatever tabs you opened alongside it. Developers and researchers working with agents are who this is aimed at. It is a concrete proposal for what an agent interface looks like once you stop treating chat as the whole surface.
