SwiftBarでMacOSのメニューバーにClaudeCodeのステータスを表示する

2026/02/07に公開
このエントリは、次の画像のようにMacOSのメニューバーにClaudeCodeのステータス表示をする設定手順のメモです。
ClaudeCodeの処理中(thinking):

PermissionRequestの回答待ち(paused):

入力待ち(waiting):

利用するツールはClaudeCode, SwiftBar, iTerm2です。
https://claude.com/product/claude-code
https://github.com/swiftbar/SwiftBar
https://iterm2.com/

 仕組み全体の仕組みは、以下のグラフのようになります。
ClaudeCodeのHookで、ステータス(PermissionRequestの回答待ちor処理中or入力待ち)をStatusファイルに出力
SwiftBarのプラグインが、Statusファイルに監視してメニューバーにステータスを表示
メニューバーからメニューが選択されたら、該当するセッションのiTerm2のタブをアクティブ化

 実装実装を示します。

 設定手順ClaudeCode, SwiftBar, iTerm2をインストールします.
上記の各ファイルを作成します。bin配下のスクリプトには実行権限を付与します.
SwiftBarのpluginディレクトリは、$HOME/dotfiles/swiftbar/bin/pluginsにします.
以上。
