Include session name in terminal tab title after /rename

[superfluidic]

Summary

When a session is renamed via /rename, the terminal tab title should include the custom name (e.g. Ohm — Claude Code instead of ⠐ Claude Code).

Current Behavior

Claude Code continuously sets the terminal tab's custom title property to ⠐ Claude Code (with rotating spinner). This overwrites any externally set title on every tick.

Attempted Workarounds (all failed)

Approach	Result
SessionStart hook with ANSI \033]0;title\007 to stdout	Captured by Claude Code, never reaches terminal
Same escape sequence to /dev/tty	Immediately overwritten by Claude Code's title loop
osascript setting Terminal.app custom title + title displays custom title	Overwritten — Claude Code resets custom title on every spinner tick

Investigation

• /rename Ohm stores a custom-title event in the transcript JSONL: {"type": "custom-title", "customTitle": "Ohm", "sessionId": "..."}
• The SessionStart hook payload includes transcript_path but not the session name
• Terminal.app confirms Claude Code owns the title: custom_title=⠐ Claude Code | displays_custom=true

Proposed Solution

When customTitle is set, include it in the terminal title string that Claude Code manages:

⠐ Ohm — Claude Code

Or at minimum, expose customTitle in the SessionStart hook payload so users can set it themselves (though this still requires Claude Code to not overwrite it).

Environment

• Claude Code 2.1.36
• macOS (Terminal.app, _GreenCRT profile)
• Hook type: SessionStart command hook
