自分のワークスペース・サーフェスを確認\ncmux list-workspaces             # 全ワークスペース一覧\ncmux tree                        # トポロジー表示（階層構造）\n```\n\nリソースは短縮 refs で参照する: `window:1`, `workspace:2`, `pane:3`, `surface:4`。\n`--id-format uuids` で UUID 形式の出力も可能。\n\n> **注意**: `cmux-send` で複数行を送る場合は `cmux-send-key return` が必須。詳細は「send の改行ルール」を参照。\n\n## 基本操作\n\n| 操作 | コマンド |\n|------|---------|\n| ペイン分割 | `cmux new-split right` (left/up/down も可) |\n| 新ワークスペース | `cmux new-workspace --cwd $(pwd)` |\n| コマンド送信 | `cmux-send --surface surface:N \"command\\n\"` |\n| キー送信 | `cmux-send-key --surface surface:N return` / `ctrl+c` / `ctrl+d` |\n| 画面読み取り | `cmux-read --surface surface:N [--scrollback]` |\n| サーフェス/WS 終了 | `cmux close-surface` / `cmux close-workspace` |\n| 一覧表示 | `cmux list-panes` / `cmux list-pane-surfaces` |\n\n## send の改行ルール\n\n**これは最も重要なルールである。**\n\n### 単一行コマンド: `\\n` で OK\n\n```bash\ncmux-send --surface surface:1 \"echo hello\\n\"\n```\n\n末尾の `\\n` が Enter キーとして機能する。\n\n### 複数行テキスト: `cmux-send-key return` が必須\n\n`\\n` は改行として送信されない。各行を個別に送り、行間で `cmux-send-key return` を使う。\n\n```bash\n# ✅ 正しい方法\ncmux-send --surface surface:1 \"line 1\"\ncmux-send-key --surface surface:1 return\ncmux-send --surface surface:1 \"line 2\"\ncmux-send-key --surface surface:1 return\n\n# ❌ 間違い — \\n は途中改行にならない\ncmux-send --surface surface:1 \"line 1\\nline 2\\n\"\n```\n\n**ルール**: 末尾の `\\n` 1個だけは Enter として機能する。文字列の途中に `\\n` を入れても改行にはならない。\n\n## 制御キーの送信\n\nプロセス中断（Ctrl+C）などの制御キーは **`cmux-send-key`** で送る。`cmux-send` では送れない。\n\n```bash\n# ✅ 正しい方法\ncmux-send-key --surface surface:N ctrl+c\n\n# ❌ 間違い — リテラルテキストが送られるだけ\ncmux-send --surface surface:N \"C-c\"\ncmux-send --surface surface:N \"\\x03\"\ncmux-send-key --surface surface:N \"C-c\"   # → Unknown key エラー\n```\n\nキー名は `ctrl+c`, `ctrl+d`, `ctrl+z`, `return`, `tab`, `escape` 等。`cmux send-key --help` で確認可能。\n\n## ラッパー使用の原則（重要）\n\n**`cmux-read` / `cmux-send` / `cmux-send-key` ラッパーを使う。** `surface:N` を渡すと自動的に正しいワークスペースを解決するため、別 workspace/window のサーフェスでも `--surface` だけで動く。\n\n```bash\n# ✅ 正しい方法 — surface ref から自動解決（window をまたいでも OK）\ncmux-read --surface surface:N\ncmux-send --surface surface:N \"command\\n\"\ncmux-send-key --surface surface:N return\n```\n\n```bash\n# ❌ 間違い — 生の cmux コマンドは別 workspace/window のサーフェスで失敗\ncmux read-screen --surface surface:S    # → \"Surface is not a terminal\" エラー\ncmux send --surface surface:S \"...\"     # → 同上\n```\n\n**理由**: 生の `cmux read-screen` / `cmux send` / `cmux send-key` の `--surface` は caller と同一ワークスペース内のサーフェスのみ有効。ラッパーは内部で `cmux tree --all --json` から workspace を解決し `--workspace` 経由で呼び直すため、cross-window でも動作する。`--workspace` 形式はそのまま通過するので、`new-workspace` フロー（後述）でも統一して使える。\n\n## 新しい surface をデフォルトで作る\n\n別文脈での実行が必要なら、**既存の surface を再利用せず `cmux new-split` で新規作成する**。既存ペインの状態（実行中プロセス、未保存の作業）を破壊するリスクがあるため、再利用は危険。\n\n**トリガー**: ユーザーが「別 surface で」「新しい surface で」「別ペインで」「split で」と指示した場合は、必ず `new-split` で新規作成する。現在の surface でそのまま実行してはいけない。\n\n```bash\nSURF=$(cmux new-split right | awk '{print $2}')\ncmux-send --surface $SURF \"command\\n\"\n# 不要になったら閉じる\ncmux close-surface --surface $SURF\n```\n\n## サブエージェント操作パターン\n\nサブエージェントを起動し、タスクを委任し、結果を回収する一連の手順。\n\n### 配置方式の選択\n\n| 方式 | 利点 | 注意 |\n|------|------|------|\n| **同一ワークスペース** (`new-split`) | PTY 遅延初期化問題を回避 | レイアウトが崩れたら `cmux-grid` で修復 |\n| **別ワークスペース** (`new-workspace`) | `close-workspace` で一括終了、`rename-workspace` で識別しやすい | PTY 遅延初期化問題の影響あり（後述） |\n\n### Step 1a: 同一ワークスペースに配置（推奨）\n\n```bash\nSURF=$(cmux new-split right | awk '{print $2}')\ncmux rename-tab --surface $SURF \"Researcher-1\"\n```\n\n### Step 1b: 別ワークスペースに配置\n\n```bash\nWS=$(cmux new-workspace --cwd $(pwd) | awk '{print $2}')\ncmux rename-workspace --workspace $WS \"Researcher-1\"\n```\n\n> **注意**: PTY 遅延初期化問題（後述）により、ワークスペースを GUI 上で一度表示する必要がある場合がある。\n\n### Step 2: Claude Code 起動\n\n```bash\ncmux-send --workspace $WS \"claude --dangerously-skip-permissions\\n\"\n```\n\n> `--dangerously-skip-permissions` は信頼できるタスクにのみ使うこと。\n\n### Step 3: Trust 検出 → 承認\n\n起動直後に Trust 確認プロンプトが表示される場合がある。`cmux-read` でポーリングし、\"trust\" や \"Yes, I trust\" を検出したら承認:\n\n```bash\nscreen=$(cmux-read --workspace $WS)\n# \"trust\" 検出 → 承認\ncmux-send-key --workspace $WS return\n```\n\n### Step 4: 起動完了の検出\n\n`❯` プロンプトが表示されるまで `cmux-read --workspace $WS` でポーリング。\n\n### Step 5: プロンプト送信\n\n```bash\n# 単一行\ncmux-send --workspace $WS \"指示テキスト\\n\"\ncmux set-status $WS \"調査中\" --icon hammer  # ステータスを設定\n\n# 複数行（cmux-send-key return で改行）\ncmux-send --workspace $WS \"1行目の指示\"\ncmux-send-key --workspace $WS return\ncmux-send --workspace $WS \"2行目の指示\"\ncmux-send-key --workspace $WS return\n```\n\n### Step 6: 完了検出\n\n`❯` プロンプトの再表示を `cmux-read --workspace $WS` でポーリングして検出。\n\n### Step 7: 結果回収 & クリーンアップ\n\n```bash\ncmux clear-status $WS                                      # ステータスをクリア\nresult=$(cmux-read --workspace $WS --scrollback)  # 全出力取得\n\n# クリーンアップ: Claude 終了 → ペイン閉じ\ncmux-send --workspace $WS \"/exit\\n\"\nsleep 2\ncmux close-workspace --workspace $WS                      # ワークスペースごと閉じる\n```\n\n> **重要**: `/exit` だけでは Claude プロセスが終了するだけでペイン（surface）は残る。必ず `close-workspace`（または `close-surface`）でペインも閉じること。`sleep 2` は `/exit` の処理完了を待つため。\n\n## new-workspace の PTY 遅延初期化問題（Issue #1472）\n\n`cmux new-workspace` で作成したワークスペースのターミナル PTY は、**GUI 上で一度表示されるまで起動しない**。\n`select-workspace` API だけでは不十分で、GUI 描画（SwiftUI レンダリング）が必要。\n\n### 症状\n\n- `cmux-send --surface surface:N` → OK を返すがコマンドは実行されない（キューに留まる）\n- `cmux-read --surface surface:N` → `Surface is not a terminal` エラー\n- ソケット API `surface.send_text` → `queued: true` だが未配信\n- ソケット API `surface.read_text` → `Terminal surface not found`\n\n### ワークアラウンド: AppleScript メニュークリック\n\nmacOS アクセシビリティ許可が必要（システム設定 → プライバシーとセキュリティ → アクセシビリティ）。\n\n```bash\n# ワークスペース作成後に GUI 表示を強制する\nWS=$(cmux new-workspace --cwd $(pwd) | awk '{print $2}')\n\n# ワークスペースのインデックスを取得\nWS_INDEX=$(cmux tree --json | python3 -c \"\nimport json, sys\ndata = json.load(sys.stdin)\nfor w in data['windows']:\n    for ws in w['workspaces']:\n        if ws['ref'] == '$WS':\n            print(ws['index'] + 1)\")\n\n# AppleScript でメニュークリック → PTY 初期化\nosascript -e \"\ntell application \\\"System Events\\\"\n    tell process \\\"cmux\\\"\n        click menu item \\\"ワークスペース $WS_INDEX\\\" of menu 1 of menu bar item \\\"表示\\\" of menu bar 1\n    end tell\nend tell\"\nsleep 2\n\n# 元のワークスペースに戻る\nORIG_INDEX=1  # 元のワークスペースの index+1\nosascript -e \"\ntell application \\\"System Events\\\"\n    tell process \\\"cmux\\\"\n        click menu item \\\"ワークスペース $ORIG_INDEX\\\" of menu 1 of menu bar item \\\"表示\\\" of menu bar 1\n    end tell\nend tell\"\n```\n\n### 注意: ソケット API のフォールバック\n\nソケット API `surface.send_text` / `surface.read_text` は、ターゲット surface の PTY が未初期化の場合、**caller の surface にサイレントにフォールバックする**ことがある。レスポンスの `surface_ref` を確認して意図した surface に送信されたか必ず検証すること。\n\n## cmux-read トラブルシューティング\n\n| 問題 | 対処 |\n|------|------|\n| 出力が空 / 古い | `cmux refresh-surfaces` してから再読み取り |\n| 長い出力が切れる | `--scrollback` を追加 |\n| 特定行数だけ欲しい | `--lines N` で行数指定 |\n| surface が見つからない | `cmux list-pane-surfaces` で refs を再確認 |\n| `Surface is not a terminal` | 生の `cmux read-screen` を使っている → `cmux-read` ラッパーに置き換える。または PTY 遅延初期化問題（上記ワークアラウンド参照） |\n\n`cmux-read` の結果がおかしい場合は `cmux refresh-surfaces` → 再読み取りの順で試す。\n\n## ロングラン実行の監視\n\ndev server やビルドなど長時間プロセスは専用ペインに分離し、`cmux-read` で定期的に監視する。\n\n```bash\ncmux new-split right              # → surface:N\ncmux-send --surface surface:N \"npm run dev\\n\"\n# ポーリングで \"ready\" 等のキーワードを検出\nscreen=$(cmux-read --surface surface:N)\n```\n\n## 通知\n\n```bash\n# アプリ内通知（ペインハイライト、サイドバーバッジ。Cmd+Shift+U で移動）\ncmux notify --title \"完了\" --body \"ビルドが成功しました\"\n\n# macOS 通知センター（サウンド付き、別アプリ使用中でも表示）\nosascript -e 'display notification \"ビルド完了\" with title \"Claude\" sound name \"Glass\"'\n```\n\n使い分け: cmux 内で注意を引く → `cmux notify`、ユーザーが別アプリにいる → `osascript`。\n\n## ステータス・プログレス表示\n\n```bash\ncmux set-status mykey \"作業中\" --icon hammer --color \"#0099ff\"  # サイドバーに表示\ncmux clear-status mykey\ncmux set-progress 0.5 --label \"ビルド中...\"                     # プログレスバー（0.0〜1.0）\ncmux clear-progress\n```\n\n## ブラウザ自動化\n\n### 開く・ナビゲーション\n\n```bash\nBSURF=$(cmux browser open https://example.com | awk '{print $2}')  # ブラウザを開く\ncmux browser $BSURF goto https://google.com   # 移動\ncmux browser $BSURF back / forward / reload   # 戻る・進む・リロード\ncmux browser $BSURF url                        # 現在の URL を取得\ncmux browser $BSURF focus-webview              # ブラウザにフォーカス\n```\n\n### スナップショットと要素参照\n\n```bash\ncmux browser $BSURF snapshot --interactive   # [ref=eN] マーカー付きで取得（操作前に必須）\n```\n\n出力例（eN が CSS セレクタとして機能する）:\n```\nheading \"Welcome\" [ref=e1]\nbutton \"Submit\" [ref=e2]\ntextbox [ref=e3]\n```\n\n| オプション | 説明 |\n|-----------|------|\n| `--interactive` / `-i` | `[ref=eN]` マーカーを付与 |\n| `--compact` | コンパクト表示 |\n| `--max-depth N` | DOM 深度制限 |\n| `--selector css` | 特定要素のみ |\n| `--cursor` | カーソル位置情報を含む |\n\n### snapshot vs screenshot の使い分け\n\n**原則: `screenshot` は視覚レイアウトのバグ調査でしか使わない。** PNG はトークンを大量消費する。値・状態・テキスト・構造の確認はすべてテキストベースのコマンドで行う。\n\n| 確認したいこと | 使うコマンド |\n|--------------|------------|\n| 入力フィールドの値 | `get value eN` |\n| 要素のテキスト内容 | `get text eN` |\n| 要素の属性（href, src 等） | `get attr eN <name>` |\n| チェックボックスの状態 | `is checked eN` |\n| 表示・有効状態 | `is visible eN` / `is enabled eN` |\n| ページ上の要素を探して操作する | `snapshot --interactive` |\n| DOM 構造・階層を確認する | `snapshot` |\n| 視覚レイアウトのバグ調査 | `screenshot`（最終手段） |\n\n**判断基準**: 「目で確認したい」と思っても、その情報が DOM から取れるなら snapshot / get 系を使う。screenshot を選ぶ前に「これは `get value` / `get text` / `snapshot` で取れないか？」を必ず自問する。フォーム送信前の値確認、入力結果の検証、要素の存在確認はすべて DOM から取れる。\n\n### 要素の操作\n\nセレクタには CSS セレクタまたはスナップショットの ref（`e2` 等）を使う。`--snapshot-after` で操作後に自動でスナップショットを取得できる。\n\n```bash\ncmux browser $BSURF click e2              #
