Describe the Bug
I had a long (multi hours long) agent conversation with Claude and it was decently persisting context.
Randomly, after a failed tool call for a powershell command, Claude completely forgot the previous last few messages and the context of our ongoing conversation.
I asked it to show me what was wrong, and it literally dumped its entire prompt (yes, the prompt with all the memories, and no it was NOT a hallucination). For obvious reasons, I won’t share it here, but its what I believe is the “generate prompt” basically the structured context.
That led me to discover two main issues in the context management I believe are bugs:
- “Next Steps Identified” was completely wrong. Its as if it had time-travelled hours back. The items here were long-past completed.
- The <deleted_files> </deleted_files> tag contents were also hours old. Its as if an old checkpoint had been internally incorrectly triggered.
This behavior of “forgetting where I am and what we were talking about” has happened in the past but this is the first time I’ve been able to diagnose the source of it because of the prompt-object output.
Steps to Reproduce
Hours-long conversation.
Expected Behavior
The expected behavior is for degraded context over hours-long conversations, not random forgetfulness and complete 180’s of personality.

Does this stop you from using Cursor
No - Cursor works, but with this issue
