An agent working on something long — researching, drafting, reconciling a set of numbers — can now keep working files: notes, plans and intermediate results it writes down as it goes and reads back later, instead of carrying everything in the conversation.

What makes this different from a scratchpad is where the files live. They are ordinary mesh content, in a working area belonging to the conversation. That means you can open them, they keep their version history, they obey the same permissions as everything else you own, and they are still there tomorrow. Nothing is hidden inside the agent.

Agents opt in, so this changes nothing for the ones that have no use for it. An agent that does declare it can read, write, list, search and delete within its own working area — and only there: a working file can never reach out into the rest of your content.

Under the hood this is our implementation of Microsoft Agent Framework's file-store abstraction. The practical consequence is that capabilities built against that framework can run on MeshWeaver and write into the mesh, rather than onto a disk that disappears with the process. The same adaptation now also serves your Skills to that framework, so a skill authored anywhere in a Space is found — no longer only the ones filed in one exact folder.
