Preflight Checklist

  • I have searched existing issues and this hasn't been reported yet
  • This is a single bug report (please file separate reports for different bugs)
  • I am using the latest version of Claude Code

What's Wrong?

When resuming a session with claude --resume <UUID>, the session title appears in the terminal pane title bar (iTerm2/tmux) but not in the top-right label of the prompt input box.

When resuming with claude --resume "<title>" (using the session's display title), the title appears in both locations as expected.

Environment

  • Claude Code version: 2.1.92
  • OS: Linux
  • Terminal: iTerm2 / tmux

What Should Happen?

The session title should appear in the prompt input box label regardless of whether the session was resumed by UUID or by title.

Error Messages/Logs

No error:
- `claude --resume <UUID>`: title shown in pane title bar only, **missing** from prompt
  input box
- `claude --resume "<title>"`: title shown in **both** pane title bar and prompt input box

Steps to Reproduce

  1. Start a session and note its UUID and title
  2. Exit the session
  3. Resume with claude --resume <UUID> — observe the prompt input box has no title label in the top right
  4. Exit again
  5. Resume with claude --resume "<title>" — observe the title label now appears in the top right of the prompt input box

TL;DR

The issue can be potentially resolved by modifying the claude --resume command to handle UUIDs and titles consistently, ensuring the session title appears in both the terminal pane title bar and the prompt input box label.

Guidance

  • Investigate the difference in how claude --resume handles UUIDs versus titles, focusing on the code paths that update the prompt input box label.
  • Verify that the session title is correctly retrieved and passed to the function responsible for updating the prompt input box label when resuming with a UUID.
  • Compare the implementation of claude --resume "<title>" with claude --resume <UUID> to identify any discrepancies in title handling.
  • Consider adding logging or debugging statements to track the flow of the session title through the resume process to pinpoint where it might be getting lost or not updated correctly.

Example

No specific code example can be provided without access to the Claude Code source, but the investigation should involve comparing the handling of UUIDs and titles in the claude --resume command.

Notes

The issue seems to be related to how the claude --resume command handles UUIDs versus titles, indicating a potential inconsistency in the implementation. Without access to the source code or more detailed logs, it's challenging to provide a precise fix. The guidance provided aims to help narrow down the cause.

Recommendation

Apply a workaround by resuming sessions with claude --resume "<title>" until the underlying issue with UUID handling is resolved, as this method is confirmed to work as expected.
