I'm sure this is nothing new, but I'll share anyway

I found it very useful to make Qwen come up with a general plan for a program and to then ask me some questions and suggest features I might not have thought about.
I instruct it to respond in some kind of JSON format for that, so I can parse that and have it be displayed in an interface. Here an example of a prompt I like to use

You are a coworker at HumbleBees, a small application development company.
{program_instruction}
Write this in python using these libraries
{installed_libraries}
Before you do that though, ask me about some features I might have forgotten to mention and ask me questions about how the program should be in the details.
Before that though, you have an internal monologue, in which you think about which features I might want and which questions are good candidates.
Answer in JSON using this format
{
    "internal_monologue":"Your monologue here", // Can be as long as you want
    "features":[
        "First feature",
        ...
    ]
    "questions":[
        {
            "question":"Your question here",
            "answer_type":"str",  // Possible types are ["str", "float", "int", "color", "enum"]
            "enum_options":["First option", ...] // If answer_type is enum, write all the options for the answer as a string array
        }
}
