[BUG] Resume conversation doesn't display previous messages in terminal

What's Wrong?

When resuming a conversation using Claude Code CLI, the previous messages from that conversation are no longer displayed in the terminal. In earlier versions, when you resumed a conversation, the terminal would show all the previous interactions, making it easy to see the context. Now, only new messages appear in the terminal, even though Claude maintains the conversation context internally and can summarize previous interactions when asked.

What Should Happen?

When resuming a conversation, the terminal should display all previous messages from that conversation, just like it did in earlier versions of Claude Code CLI. This helps users see what was discussed without having to rely on Claude to summarize the history.

Error Messages/Logs

No error messages - this is a behavioral change/regression in the UI

Steps to Reproduce

1. Start a conversation with Claude Code CLI
2. Have several back-and-forth exchanges (e.g., ask Claude to help with a task)
3. Exit the conversation
4. Resume the same conversation later
5. Observe that previous messages are not displayed in the terminal
6. Note that Claude still has access to the conversation history (can summarize it on request), but it's not visible to the user in the terminal output

Claude Model

Sonnet (default)

Is this a regression?

Yes, this worked in a previous version

Last Working Version

The last version I had installed was 2.0.1, before that 2.0.0 and before that 1.x. It definitely worked in 1.x and likely in 2.0.0 and 2.0.1

Claude Code Version

2.0.5 (Claude Code)

Platform

Anthropic API

Operating System

macOS

Terminal/Shell

IntelliJ IDEA terminal

Additional Information

Note that I am using Fish (in IntelliJ IDEA terminal).

This is a UX regression that makes it harder to resume work on complex tasks, as users lose visibility into what was previously discussed and decided. The conversation context is preserved (Claude can reference and summarize previous messages), but the lack of terminal display makes it difficult for users to quickly review the conversation history.
