Feature Request

Summary: Update the terminal tab title to show a spinner/loading indicator while Claude is actively processing, similar to how many CLI tools use escape codes to update the tab title dynamically.

Desired Behavior

While Claude Code is working (processing a prompt), the terminal tab title should display a loading indicator, e.g.:

⠋ Claude Code — working...

And revert to the default title once idle:

Claude Code

Why This Is Useful

  • Users who have multiple terminal tabs open can glance at the tab bar to see if Claude is still working
  • Reduces context-switching — no need to click into the Claude tab just to check status
  • Common UX pattern in modern CLIs (e.g., npm, webpack, etc.)

Implementation Suggestion

This could be achieved via ANSI/xterm escape codes:

\033]0;⠋ Claude Code — working...\007

Triggered at the start of a response and cleared when complete. Could also be exposed as a configurable option in settings.json.

Current Workaround

Hooks can set the tab title at SessionStart/Stop boundaries, but there is no way to trigger a live spinner during active processing.

extent analysis

TL;DR

Implementing ANSI/xterm escape codes to update the terminal tab title dynamically can achieve the desired loading indicator behavior.

Guidance

  • Investigate using ANSI/xterm escape codes, such as \033]0;⠋ Claude Code — working...\007, to update the terminal tab title.
  • Trigger the escape code at the start of a response and clear it when complete to create a live spinner effect.
  • Consider exposing this feature as a configurable option in settings.json for user customization.
  • Review existing hooks, such as SessionStart/Stop, to determine if they can be leveraged or extended to support the dynamic tab title update.

Example

print("\033]0;⠋ Claude Code — working...\007")  # Set tab title with loading indicator
# ... processing code ...
print("\033]0;Claude Code\007")  # Reset tab title when complete

Notes

The implementation may vary depending on the programming language and terminal emulator being used. Additionally, some terminals might not support ANSI/xterm escape codes, which could limit the compatibility of this feature.

Recommendation

Apply workaround using ANSI/xterm escape codes, as it provides a straightforward and widely adopted solution for dynamically updating the terminal tab title.
