claude-code - 💡(How to fix) Fix [Bug] /rewind default option unsafe: rolls back code without confirmation or clear warning [2 comments, 3 participants]

[{"error":"Error: NON-FATAL: Lock acquisition failed for /Users/robmorris/.local/share/claude/versions/2.1.114 (expected in multi-process scenarios)\n at sd_ (/$bunfs/root/src/entrypoints/cli.js:2751:2177)\n at WH8 (/$bunfs/root/src/entrypoints/cli.js:2751:1257)\n at processTicksAndRejections (native:7:39)","timestamp":"2026-04-19T20:53:14.148Z"}]

TL;DR

The /rewind command should be modified to clearly indicate the potential consequences of its operations, request confirmation before proceeding, and default to a safer option to prevent accidental data loss.

Guidance

• Consider changing the default option of /rewind from "code and conversation" to "chat only" to minimize the risk of accidental data loss.
• Add a confirmation prompt before executing the /rewind command to ensure the user understands the potential consequences of their action.
• Provide a clear indication of what will be rolled back and the potential "blast radius" of the operation to help users make informed decisions.
• Review the UI/UX of the /rewind command to ensure it effectively communicates the differences between its recovery and context management uses.

Example

No code snippet is provided as the issue focuses on the UX and functionality of the /rewind command rather than a specific code implementation.

Notes

The provided error message does not seem directly related to the issue described, as it mentions a lock acquisition failure, which may be a separate problem. The focus of the issue is on improving the safety and usability of the /rewind command.

Recommendation

Apply a workaround by using the /rewind command with caution and ensuring that the "chat only" option is selected by default, until a more permanent fix can be implemented to address the safety concerns.
