TL;DR

The issue with the auto permission mode not being inherited by new sessions and unable to be set mid-session may be due to a validation or normalization step that strips the "auto" value when writing the per-session state file.

Guidance

• Investigate the code path that writes permissionMode to the session JSON on first message completion to identify any validation or normalization steps that might be causing the issue.
• Check the per-session state files at C:/Users/[user]/AppData/Roaming/Claude/claude-code-sessions/[account-uuid]/[workspace-uuid]/[session-id].json to see if the permissionMode field is being overwritten or modified after the first message.
• Verify that the defaultMode setting in ~/.claude/settings.json is being read correctly and applied to new sessions.
• Consider adding logging or debugging statements to track the value of permissionMode throughout the session to identify where it is being changed.

Example

No code snippet is provided as the issue does not contain sufficient information to create a specific example.

Notes

The provided error messages do not seem to be directly related to the issue with the auto permission mode. The issue may be specific to the Windows platform or the version of Claude Desktop being used (2.1.77).

Recommendation

Apply a workaround by setting defaultMode to a different value, such as "bypassPermissions", to see if the issue is specific to the "auto" value. This may help identify if the issue is with the validation or normalization step or with the auto value itself.
