+### Форма с чекбоксами и радиокнопками (`form`)
+
+Отображает список полей с возможностью навигации и переключения. Возвращает строку с ID всех включённых/выбранных полей через пробел.
+
+```json
+{
+  "type": "form",
+  "prompt": "Параметры поиска:",
+  "fields": [
+    {"id": "verbose",  "label": "Подробный вывод",   "field_type": "checkbox", "default": false},
+    {"id": "php",      "label": "PHP файлы (*.php)",  "field_type": "radio",    "group": "ftype", "default": true},
+    {"id": "js",       "label": "JS файлы (*.js)",    "field_type": "radio",    "group": "ftype", "default": false}
+  ]
+}
+```
+
+| Поле | Описание |
+|---|---|
+| `id` | Идентификатор, возвращается если поле включено |
+| `label` | Отображаемый текст |
+| `field_type` | `"checkbox"` или `"radio"` |
+| `default` | Начальное состояние |
+| `group` | Группа радиокнопок — одновременно активна только одна в группе |
+
+**Ответ:** строка с ID активных полей через пробел: `"verbose php"`
+
+**Клавиши внутри формы:** `↑`/`↓`/`j`/`k` — навигация, `Space` — переключить, `Enter`/`l` — применить, `Esc` — отмена.
+
+**Важно:** весь JSON должен быть на **одной строке** — протокол читает строки, не блоки.

 ### Запуск внешнего приложения (`exec`)
 
 Временно **передаёт терминал** внешней программе (mysql, vim, htop и др.). Клиент скрывает TUI, программа работает на полном экране, после завершения TUI восстанавливается. Возвращает код завершения.
