What
The permission mode is the setting that controls how often Claude Code stops to ask before it acts. Choosing auto mode now first checks whether auto mode is available to you. If that check has not come back yet, the switch is refused with this message:
Cannot set permission mode to auto: auto mode availability is not known yet · ask again
When your settings change, Claude Code runs the check again.
Why
Auto mode can now be refused or put off while its availability is unknown. If you see the message above, wait a moment and ask for auto mode again.
