Antigravity IDE用のCLIツールをインストールする
Googleが展開する「Antigravity」シリーズは、2026年5月のバージョン2.0へのメジャーアップデートに伴い、製品の位置づけが大きく整理されました。「Antigravity」はAIエージェントを指揮するプラットフォーム全体（またはその中核アプリ）であり、「Antigravity IDE」はその中の一要素である“コード編集用エディタ”という位置づけです。
これを「新旧のツール名・CLIコマンド名」の観点で整理すると以下になります。

私の環境ではAntigravity 2.0をインストールした結果、CLIからAntigravity IDEを起動するには「agy-ideコマンドを利用可能な状態にする」必要がありました。今回はその際の作業内容をメモしておきます。私の場合は「agy-ideコマンドは存在しているがPATHが通っていない」状態になっていました。

agy-ideをインストールする(インストールされていた)
Antigravity IDE上でCmd+Shift+Pを押し、コマンドパレットからShell command: install agy-ide command in PATHを選択します。
しかし、私の環境では既にインストール済みのようです。
EEXIST: file already exists, symlink '/Applications/Antigravity IDE.app/Contents/Resources/app/bin/antigravity-ide' -> '/Users/USERNAME/.antigravity-ide/antigravity-ide/bin/agy-ide'
agy-ideへPATHを通す
私の環境ではagy-ideにPATHが通っていないようです。
% which agy-ide
agy-ide not found
~/.zshrcなどにagy-ideへのPATHを追加します。
export PATH="$PATH:$HOME/.antigravity-ide/antigravity-ide/bin"
これでCLIからagy-ideを実行するとGUIのAntigravity IDEが起動するようになりました。
