# Documentation
- Class name: Get Prompt
- Category: Bmad/dump
- Output node: True
- Repo Ref: https://github.com/bmad4ever/ComfyUI-Bmad-Custom-Nodes

该节点旨在处理和修改用于API交互的给定提示结构，具体做法是移除不必要的元素，并根据指定的输出模式（如打印到控制台或保存到文件）进行调整。该节点在准备提示以供执行或审查方面发挥着关键作用，确保只保留相关数据并以适当的格式呈现。

# Input types
## Required
- api_prompt
    - 指定处理后提示的输出模式，如打印到控制台或保存到文件。这个选择决定了最终提示结构的处理方式，影响节点的执行流程和提示数据的呈现方式。
    - Comfy dtype: COMBO[STRING]
    - Python dtype: List[str]

# Output types
该节点没有输出类型。


## Usage tips
- Infra type: `CPU`
- Common nodes: unknown
