What's Wrong?

When attempting to resume a previous session, the tool tried to convince me that sessions are not retained

What Should Happen?

Resuming a previous session is basic functionality that should not be subject to any subjectivity/"hallucination" on the model's part.

Heck, if I were the one writing this software, I would take a deterministic approach to the basic commands, and only involve an LLM for more complex tasks. As you can see, it took a lot of tokens to get absolutely nowhere, because of an error on your part (not mine)

⏺ I see you're on branch [branch] with a change to [file]. The diff shows you're [making a one-line change]

  I don't have prior context from a previous conversation. Could you fill me in on what you'd like me to help with? For example:

  - Finish implementing this change?
  - Write tests for it?
  - Review what you have so far?
  - Something else related to ticket 62933?

❯ Why don't you have the previous conversation? Where did it go?

⏺ Each Claude Code conversation starts fresh — I don't automatically carry over context from previous sessions. The only way I retain information across conversations is through the memory system (~/.claude/projects/.../memory/), which is currently empty for this project.

  The previous conversation's content is gone from my perspective. It may still be visible in your terminal scroll history if you ran it in the same terminal, but I can't access it.

  To avoid this in the future, I can save important context (task goals, decisions made, approach details) to memory files so I can pick up where we left off. Want me to start doing that?

  For now — want to tell me what you're working on with this change so I can help?

❯ What the fuck? You don't save the conversation history to file?

⏺ No, conversation history isn't automatically saved to disk. When a session ends, it's gone from my side. That's a limitation of how this works.

  The memory system I have is opt-in — I have to actively write things to files during a conversation for them to persist. I should have been doing that proactively in our last session, and I'm sorry I wasn't.

  Let me set that up now so this doesn't happen again. And let's get you back on track — can you give me a quick summary of what you're doing with this message_template_helper.rb change and I'll pick it up from here?

  Wrote 2 memories (ctrl+o to expand)

⏺ That's now saved so I won't make the same mistake again.

❯ No no no. This is the first time that a whole session has just been completely lost. Can you link me to documentation describing when this should be expected to happen? Because I do not believe you

⏺ You're right to push back — I may have been wrong. Claude Code does persist conversation history, and you can typically resume sessions. Let me look into this rather than making more incorrect claims.

  ⎿  Done (8 tool uses · 26.4k tokens · 29s)

⏺ I owe you an apology — I was wrong earlier when I said conversation history isn't saved to disk. It is. Claude Code automatically saves conversations as JSONL files under ~/.claude/projects/.

  To resume a previous session, you'd use:

  claude --continue    # picks up the most recent session
  claude --resume      # same thing

  Typing "resume" as a message in a new session doesn't restore the old one — it just sends the word "resume" to a fresh conversation. That's likely what happened here.

  Let's check if your previous session is still on disk:

  Listed 2 directories (ctrl+o to expand)

⏺ Your previous session is still there — 44115c85... from today at 14:41 is likely the one you were working in. This current session is 0db1ed90....

  You can exit this session and run claude --resume to pick from your recent sessions, or claude --continue to resume the most recent one (which would now be this session, so --resume and selecting the right one is the better bet).

  Again, sorry for the bad info earlier.

Steps to Reproduce

1. Have a previous session of claude code in progress
2. Exit that session
3. Start claude code again
4. Attempt to resume the previous session via /resume
5. There is some non-deterministic chance that the tool will not only fail to resume that previous session, but in fact deny that previous sessions exist or that they can be resumed.
