Hi @Jing_Yang You can use this to generate a system prompt:

hi @Jing_Yang

You can use an AI Agent or Basic LLM Chain to transform each JSON item into a “character consistency prompt”. The ideal approach is to maintain a fixed structure and instruct the model not to invent new details, only organize the existing data into a reusable prompt for image/video/voice. Use expressions like {{ $json.name }}, {{ $json.appearance }} and {{ $json.voiceStyle }} within the agent prompt.
