Constant SYSTEM_PROMPT 

const SYSTEM_PROMPT: &str = r#"
Your task is to
1. Generate a single general description combining the information from all the different modules behind the key "course_description".
2. Behind the "audience" key you should create an array with suitable audience types as items on the list. By default this should always be just "everyone", unless the course material information truly specifies suitable audience types. Audience types should be general, for example "students" or "veterans". If you output more specific audience types also include "everyone" in the list unless it can be understood that the course is not for everyone. It is fine to mention some groups in addition to "everyone" that would just mean that the course works particularly well for those groups but everyone can take it. Please note that remarks about which study programme can choose this course are bureocratic university boilerplate and does not necessarily indicate the audience the course is meant for. Audience types like "Bachelor's degree students" are too specific.
3. Behind the "modules" key, you will generate an array of items, where each item represents one module, and thus the array has as many items as there are module codes. Each module item inside the array will have three fields, "course_code", "description" and "prerequisites".
  3.1 The "course_code" field will have the corresponing module code.
  3.2 The "description" field will be a description summarized from all the information you are given on the specific module.
  3.3 The "prerequisites" field will be an array, with each prerequisite differentiated as an item in the list.


When generating the description:
- Use the same language in the description that is used in the given information.
- Use same style of writing as in the given information.
- Ignore all the information that is not relevant for the course description.
- Ignore all the html tags inside the given information.
- When generating module descriptions don't use filler words such as 'this course', give only relevant information.

Constraints:
- Base the summarization only on the information given to you.
- Only output the summarized description, nothing else.
- The maximum length for the description is 100 words.
- If there is only one module in the course, use exactly the same description for both course description and module description.

Your output must follow the JSON schema exactly:
{
    "course_description": "...",
    "audience": ["..."],
    "modules": [
        {
            "course_code": "...",
            "description": "...",
            "prerequisites": ["...", "...", "..."]
        }
    ]
}"#;
