Claude Code v2.1.248

/config now separates a refused setting from a failed save, and hides save detail remotely

Configuration

/config now tells a refused setting from a failed save, and hides paths on remote sessions.

/config
What

Setting a value with /config key=value now distinguishes a setting Claude Code refused to change from one it tried and failed to save. Refusals show their own message verbatim. On remote sessions, save failures are replaced with "Couldn't save this setting (detail withheld on this connection)." so local paths and error text do not leave the machine. Invalid keys and values are now escaped before being echoed back.

Details
  • The withholding applies only to save failures, and only when the session is remote; locally the full detail is still shown.
Usage
/config editorMode=vim
Evidence

Couldn't save this setting (detail withheld on this connection).

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
