Done.

Add the following to ~/.claude/settings.json (merge with any existing keys):

  {
    "statusLine": {
      "type": "command",
      "command": "bash $CLAUDE_DIR/statusline.sh"
    }
  }

Or merge automatically with jq:

  jq '.statusLine = {"type":"command","command":"bash $CLAUDE_DIR/statusline.sh"}' \\
     ~/.claude/settings.json > /tmp/settings.json && mv /tmp/settings.json ~/.claude/settings.json

Restart Claude Code to activate the status line.
