There is no set meaning for it. It could refer to a wall of text, the top few lines on your CV or another name for a cover letter. Does it have a word limit to help figure out what it is?

If it's a beefy bit of text, aim for just under that amount of text. Go through the job description and cover all the points in there, and refer to previous experiences (could be within work, uni, school, volunteering, anything really, tbh could make it up or exaggerate an event) to demonstrate that skill of requirement. Try to use I did x rather than we or x happened. In the examples, you could have something that went wrong and what you did to fix it. (E.g needs to be a team player in job description becomes I work well with team members by listening to the input from others and also putting my point of view across where relevant and helpful. For example, in my final year at university we did a group project on x. Two of my team members got into an argument about which direction to go. I talked to both of them to calm down and as a group, I encouraged everyone to evaluate each idea by the positives as well as areas of improvement. That way, we were able to take the best option for the group and move forward to complete the project.) Or some bollocks like that...

Don't use AI to blindly write it. You can use it top give you examples of what to put in or to proof read but chances are 90% of people will just use AI which they'll be able to tell and they'll sound the same so not using it will stand out.

Don't spend too much time and effort unless you really really want the job. They'll be mostly skimmed through if read at all.
