Unclear It is not clear what makes a session count as having no disk, so a reader cannot tell when these limits apply to them.
What
A session is one continuous conversation with Claude Code. Claude Code now recognises a session that has no disk, meaning nowhere to save files, and changes how three features behave in it:
Resuming a teammate (another agent that works alongside the main one) is refused with the error "teammate resume refused in a session with no disk".
The main agent's MCP servers are ignored. MCP servers are outside programs that give Claude Code extra tools.
Discovering models through a gateway is switched off. A gateway is a service that sits between Claude Code and the models it uses.
Why
In a session with no disk, you cannot pick up a teammate where it left off, and the main agent works without its MCP tools. If something you rely on is missing in such a session, this is the likely reason.
