Teach and validate LINE Messaging API payload design. Use when building or reviewing LINE bots, webhook handlers, reply or push message flows, Flex Messages, Quick Replies, Rich Menus, supported LINE message types, or LINE action objects. Use this skill when the model must choose the right LINE UI surface and produce conservative, LINE-compatible JSON without inventing unsupported fields.
