If you’ve decided to include “detail-oriented” on your skills list, it’s important that you also distribute it throughout your resume and cover letter. You should only include “detail-oriented” on your skills list if you feel like it’s a skill that’s helped you significantly over the years. You should be able to list at least a few experiences in your past jobs where being detail-oriented helped you do better work. Examples may be that you caught a typo in a large advertising campaign or you fixed formatting issues to look better to the customer. If you can’t provide an example of how detail-oriented you are, you might want to consider listing a different skill instead.
