[Bug] Anthropic API Error: Model temporarily unavailable in auto mode safety classification

Bug Description
opiu⎿  Error: claude-opus-4-8[1m] is temporarily unavailable, so auto mode cannot determine the safety of Bash right now. Wait briefly and then try this action again. If it keeps failing, continue with other tasks that don't require this
action and come back to it later. Note: reading files, searching code, and other read-only operations do not require the classifier and can still be used.
⎿  Interrupted · What should Claude do instead?
