FAQ

Questions about happ_assistant_prompt_edit

What does the happ_assistant_prompt_edit tool do? +

Точечные правки промпта ассистента БЕЗ пересылки всего текста (анкерные замены как в редакторе: oldText → newText). Используй ВМЕСТО happ_assistant_update.promptText для любых больших промптов и вставок секций — не выгружай токен и не делай прямые HTTP-запросы к API. Каждый oldText должен встречаться в промпте РОВНО один раз (добавь контекст вокруг, чтобы стало однозначно); вставка секции = oldText «якорная строка», newText «новая секция + якорная строка». Как и с promptText: сначала покажи человеку точный диф, дождись подтверждения, потом вызывай с promptChangeConfirmed=true. (PATCH /assistants-new/:id).
