Claude chat history missing in VS Code

Users are reporting that their past conversations with Claude in VS Code have suddenly vanished. This is a reminder to back up important code or instructions elsewhere.

A recent report on Reddit shows a user lost almost all their chat history in the VS Code editor, leaving only one session behind. This issue can happen due to extension updates, local cache clearing, or sync errors between the computer and the AI service. For makers who rely on AI to track project logic, losing these chats means losing the context of past decisions. It highlights the risk of relying solely on an extension's local history for long-term project memory.

Key points

  • Check if your VS Code extension is up to date or if you logged out.
  • Avoid keeping critical project documentation only inside chat windows.
  • Copy important code snippets or explanations to a permanent file.
