File System in Multi-Agent Systems

Agent accesses a virtual file system: four types of areas are mounted into a single tree.

Agent’s Scratchpad — private, destroyed with the instance, trial and error remains within it.
Shared Multi-Agent Space — artifact exchange, visible to the user, requires concurrency control.
Mounted External Resources (Google Drive, Notion via adapters) — limited by external permissions, mostly read-only.
Built-in System Resources (Skills, templates) — read-only, stable.

Passing a file path instead of content saves context.

OS Philosophy: isolation by default, sharing is declared explicitly.
