Amending built-in prompts

Describe the problem/error/question

I have noticed that adding some nodes (for example Structured Output Parser) automatically adds an additional prompt to the overall prompt provided to the LLM model (eg Conversational Agent). Is there a way to amend that built-in prompt?

What is the error message (if any)?

Please share your workflow

(Select the nodes on your canvas and use the keyboard shortcuts CMD+C/CTRL+C and CMD+V/CTRL+V to copy and paste the workflow.)

Share the output returned by the last node

Tip for sharing information

Pasting your n8n workflow


Ensure to copy your n8n workflow and paste it in the code block, that is in between the pairs of triple backticks, which also could be achieved by clicking </> (preformatted text) in the editor and pasting in your workflow.

```
<your workflow>
```

That implies to any JSON output you would like to share with us.

Make sure that you have removed any sensitive information from your workflow and include dummy or pinned data with it!


Sure, you can customize the prompt. What stops you? Could you show where you got stuck?

Maybe I am missing something, but from logging it looks like there is a bult-in prompt that comes with Structured Output node that I cannot find a way to edit.
