What's Wrong?

The /resume slash command used inside an active Claude Code terminal session only displays 10 conversations in the picker, with no ability to scroll further through the list (arrow down cycles back to the top). In contrast, claude --resume from the CLI displays the full conversation history with proper scrolling.

\resume inside active session:

claude --resume:

<img width="1234" height="224" alt="Image" src="https://github.com/user-attachments/assets/6bb2e72b-51bd-402d-9fad-83a217c927cb" />

The VS Code extension's "Past Conversations" view also shows the complete history going back a month+.

What Should Happen?

/resume inside an active session should show the same full, scrollable conversation list as claude --resume from the CLI.

Actual Behavior

• /resume (inside session): Shows only 10 conversations, no scroll/pagination
• claude --resume (from CLI): Shows full history, scrollable ✅
• VS Code extension "Past Conversations": Shows full history ✅

Steps to Reproduce

1. Have at least 11 conversations in your history
2. Start a new Claude Code session in the terminal: claude
3. Type /resume
4. Observe: only 10 conversations appear
5. Press arrow down past the last item — it cycles back to the top (no pagination)
6. Exit the session
7. Run claude --resume from the CLI
8. Observe: full conversation history is displayed with proper scrolling
