claude-code - 💡(How to fix) Fix Permission mode toggle (shift+tab) does not persist to settings.json [1 comments, 2 participants]

TL;DR

The issue can be temporarily worked around by manually editing ~/.claude/settings.json to reflect the desired permission mode, but a permanent fix requires ensuring that the Claude Code CLI properly updates this file when the user toggles the permission mode via shift+tab.

Guidance

• Verify that the shift+tab shortcut is correctly bound to the function responsible for toggling the permission mode and that this function includes the logic to update ~/.claude/settings.json.
• Check the code for any errors or exceptions that might occur when attempting to write to ~/.claude/settings.json, which could prevent the file from being updated.
• Confirm that the subagents are correctly reading the defaultMode from ~/.claude/settings.json and that there are no caching issues that might cause them to use a stale version of the settings.
• Investigate if there are any file system permissions issues that could prevent the Claude Code CLI from writing to ~/.claude/settings.json.

Example

No specific code example can be provided without access to the Claude Code CLI's source code, but the fix would involve ensuring that the function toggling the permission mode also updates the defaultMode in ~/.claude/settings.json.

Notes

The provided workaround suggests that the issue is with the persistence of the setting rather than its application during the current session. The fix must ensure that the defaultMode in ~/.claude/settings.json is updated whenever the user changes the permission mode.

Recommendation

Apply the workaround by manually editing ~/.claude/settings.json until a fix is implemented that ensures the Claude Code CLI correctly updates this file when the permission mode is toggled, as this will at least allow users to set the desired mode persistently.
