Claude Code now recognises a session that has no disk, meaning nowhere to save files, and changes how three features behave in it:\n\n- 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\".\n\n- The main agent's MCP servers are ignored. MCP servers are outside programs that give Claude Code extra tools.\n\n- Discovering models through a gateway is switched off. A gateway is a service that sits between Claude Code and the models it uses.\n\n**Why**\n\nIn 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.\n\n- Area: Diskless Sessions\n- Tier: Under the hood\n- Useful: 2\/5\n- Signal: 3\/5\n- Scope: individual\n- Heads-up: no"}
