Unclear It is not clear what makes a session diskless or whether any session can be diskless today.
What
Claude Code is gaining a diskless mode, where a session has no local storage to read from or write to. When the same internal check is true:
- The auto-mode classifier dump, the session title file and the scoping record for forked skills are not written. The scoping record reports
disklesswithnot written: no storage backend, or no key for the target path. - Taking over an agent whose record is diskless now fails with an error.
- Skill folders are not scanned, except for policy settings, and the log says
the session is diskless, so no skills load from it. - Uploading the home-directory inventory is skipped with reason
diskless. - The environment details sent at session start report the shell as
none. - Two file readers report the file as absent.
Separately, the spare background job gains a guard that looks like a check for Claude Code exiting.
Why
This prepares Claude Code to run where there is no local disk, such as a hosted session. In that mode, skills and local files will not load.
