 지원하는 텍스트 블록의 최소 형태는 `<tool_call><function=<name>><parameter=<key>>JSON-or-text</parameter></function></tool_call>` 또는 `{{function_name(key=Python/JSON-like-literal)}}`이다.
 템플릿 호출 형태의 인자는 single-quoted string, `True`/`False`/`None`, 배열, 객체를 JSON `arguments` 문자열로 정규화한다.
 `commands` 배열의 command 객체에 UI 설명용 `description`이 포함되면 tool schema 검증을 위해 제거한다.
-`commands` 배열 내부의 `runInTerminal`은 top-level 실행 힌트로 올리고, shell 연산자/리다이렉션/quote/공백 인자 등 shell 해석이 필요한 명령 문자열은 top-level `runInTerminal: true`를 부여한다.
+`commands` 배열 내부의 `{command: "...", description, runInTerminal}` 형태는 tool schema와 기존 shell 실행 경로를 맞추기 위해 `commands: ["..."]` 형태로 정규화하며, `runInTerminal`은 출력하지 않는다.
 호환성을 위해 `tool_choice`가 생략되었거나 `auto`/강제 tool 선택 형태로 들어오면 내부 실행 입력에서는 `tool_choice: "none"`으로 낮춰 백엔드의 auto tool-calling 요구 조건에 의해 요청 전체가 실패하지 않게 한다.
 `parallel_tool_calls`와 `stream_options`는 클라이언트 호환성을 위해 수신하지만 현재 Edge 실행 의미에는 반영하지 않는다.
