Unclear The finding does not say which interface returns this result.
What
Auto mode is a permission mode that lets Claude Code decide on more actions without asking you each time. When a request to switch to it fails, the result now includes a code field naming the reason. Examples include auto_mode_fast_mode and auto_mode_model. If there is no more specific reason, the code is auto_mode_unavailable.
Why
A program that asks Claude Code to switch modes can now tell why the switch failed without parsing an error message. It can then react, or explain the failure to you.
