Based on my conversation with @karmi, I will update the prompt to better follow the Git commit best practices.

Inspiration:

• https://github.com/PublicDataWorks/verdad/blob/main/prompts/Stage_1_Preprocess_detection_prompt.md

Also, https://www.conventionalcommits.org/en/v1.0.0/#summary is a good reference.
