[FEATURE] Reset terminal title to default on /clear command

Preflight Checklist

• [x] This is a single feature request (not multiple features)

Problem Statement

When using /clear to start a fresh session, Claude Code retains the previous session's terminal title (e.g., * Previous Task Name). This creates confusion because:

1. The terminal title no longer reflects the current session's purpose
2. When managing multiple terminal tabs, stale titles make it difficult to identify which tab contains which work
3. The /clear command resets conversation context but leaves visual artifacts from the previous session

This is part of a broader pattern where /clear doesn't fully reset session state (see related issues below).

Proposed Solution

When /clear is executed, Claude Code should reset the terminal title to a sensible default state. Options include:

1. Reset to generic default (e.g., claude or Claude Code)
2. Reset to working directory (e.g., claude - projectname)
3. Clear title entirely (let the terminal's default title behavior take over)

The simplest implementation would emit the appropriate OSC escape sequence to reset/clear the title when /clear runs.

Alternative Solutions

Workaround: SessionEnd hook

Add this to ~/.claude/settings.json to reset the terminal title on /clear or exit.

macOS / Linux:

{
  "hooks": {
    "SessionEnd": [
      {
        "hooks": [
          {
            "type": "command",
            "command": "printf '\\033]0;\\007' > /dev/tty"
          }
        ]
      }
    ]
  }
}

Windows (Command Prompt) - untested:

{
  "hooks": {
    "SessionEnd": [
      {
        "hooks": [
          {
            "type": "command",
            "command": "cmd /c title Command Prompt"
          }
        ]
      }
    ]
  }
}

Workaround: Manual reset

Run this command to reset the title during a session:

printf '\033]0;\007'

Or set a custom title:

printf '\033]0;My Title\007'

Workaround: Disable title changes entirely

Prevent Claude Code from ever modifying the terminal title:

{
  "env": {
    "CLAUDE_CODE_DISABLE_TERMINAL_TITLE": "1"
  }
}

While these workarounds exist, built-in support would provide a more consistent and discoverable experience.

Use Case Example

After /clear, terminal tabs retain stale titles from previous tasks, making multi-tab navigation unreliable.

Additional Context

This is part of a broader pattern where /clear doesn't fully reset session state:

• #16217 - Status line shows 102% after /clear command
• #16189 - /clear does not reset context_window.total_input_tokens in statusline JSON
• #14913 - Status line doesn't refresh context tokens after /clear

Related terminal title issues:

• #7229 - Terminal window title settings (general title customization)
• #11554 - Terminal title not updated on resume/foreground
• #3396 - Disable terminal name changing (introduced CLAUDE_CODE_DISABLE_TERMINAL_TITLE)

Ideally, /clear would provide a complete reset of all session-specific visual state, including both the status line metrics and the terminal title.
