 ## Display modes
 
-Settings → General → Work details offers `compact`, `standard` (default), `detailed`, and `verbose`; its description is “Choose how much detail to show for tool calls”. A saved `normal` reads as `standard`, and a saved `expanded` reads as `detailed`, without automatic write-back. Existing `detailed` remains `detailed`. Missing or invalid values, including the period before Host settings arrive, use `standard`; invalid values in other settings still fail validation.
