Code Example

Me: I'm going to give you three attachments
C: Okay, waiting
Me: Uploads attachment 1
C: Logged, give me the next
Me: Uploads attachment 2
C: Logged, give me the next
Me: Uploads attachment 3
C: Logged, anything else? 
Me: No, start the analysis.
C: You only gave me 1 document, did you mean to give me 3?

Preflight Checklist

  • I have searched existing issues and this hasn't been reported yet
  • This is a single bug report (please file separate reports for different bugs)
  • I am using the latest version of Claude Code

What's Wrong?

Two potentially related issues:

  1. Midstream conversation loss
  2. Chat history Loss

Midstream Conversation Loss

Me: I'm going to give you three attachments
C: Okay, waiting
Me: Uploads attachment 1
C: Logged, give me the next
Me: Uploads attachment 2
C: Logged, give me the next
Me: Uploads attachment 3
C: Logged, anything else? 
Me: No, start the analysis.
C: You only gave me 1 document, did you mean to give me 3?

At this point, I scroll back up and my conversation looks like this:

Me: I'm going to give you three attachments
C: Okay, waiting
Me: Uploads attachment 1
C: Logged, give me the next
Me: No, start the analysis.
C: You only gave me 1 document, did you mean to give me 3?

This happens frequently

Chat History Loss

Entire chats disappear. I've even seen instances where ALL of my chats disappear. This just happened, and I'm uncertain it will come back.

See: #14225 <- not sure why this was closed, it's a critical unfixed issue.

What Should Happen?

This data should not be lost. Cache it locally and restore if needed, but make sure it doesn't drop entirely. This is reminiscent of the MS Word days before AutoSave, but with an aggressive toddler randomly shutting down the computer. Unacceptable for a production tool.

TL;DR

The issue can be mitigated by investigating the conversation history storage and retrieval mechanism to prevent midstream conversation loss and chat history disappearance.

Guidance

  • Review the conversation history storage mechanism to ensure it is properly caching and restoring conversations, especially when the user scrolls back up or restarts the conversation.
  • Investigate the possibility of a race condition or asynchronous issue that may be causing the conversation history to be lost or overwritten.
  • Check the code for any recent changes that may have introduced this regression, as the issue is reported to have worked in a previous version.
  • Consider adding additional logging or debugging statements to help identify the root cause of the issue.

Example

No code snippet can be provided without more information about the underlying implementation.

Notes

The issue is reported to be inconsistent and difficult to reproduce, which may make it challenging to identify the root cause. The fact that it is a regression and worked in a previous version suggests that a recent change may be the culprit.

Recommendation

Apply workaround: Implement a temporary caching mechanism to store conversation history locally and restore it when needed, until the root cause of the issue can be identified and fixed. This will help prevent data loss and provide a better user experience.
