Terminal title spinner animation causes tab width to constantly change

Description

The new terminal title behavior (introduced in v2.1.6) sets the title to "Claude Code" with an animated spinner glyph while thinking.

Problem

The spinner characters (⠋ ⠙ ⠹ ⠸ ⠼ ⠴ ⠦ ⠧ ⠇ ⠏) have different widths, causing the terminal tab to constantly resize/flicker during thinking. This is visually distracting, especially when working with multiple tabs open.

Environment

• Windows Terminal
• Claude Code v2.1.6

Suggestion

Either:

1. Remove the spinner from the terminal title entirely (keep it in the terminal output only)
2. Use a fixed-width character for the spinner
3. Use a static glyph in the title instead of an animated one
