What
Some sessions run tools on a remote machine, called a tool host. Before, Claude was only told when a host went offline. Now:
- Claude is told
<host> is reachable againwhen an offline host comes back, and that nothing was replayed. - It is warned that a command the session gave up on may still be running, so it should not resend it blindly.
- The
tool_hosts_noticenow carries anawaylist of hosts alongside itslines. - Claude Code tracks which host still has a call outstanding.
Why
This helps avoid the same command running twice after a remote machine reconnects.
