A personal agent skill captures choices that are specific to an individual, such as preferred writing style, required comparison fields, or rules for handling unknown information. The goal is to make repeated tasks reflect that person's established preferences.
Personal guidance should remain editable because preferences and circumstances can change. It should also be applied only in appropriate contexts rather than treated as a universal rule for every user or website.

A personal agent skill is like a note that reminds your AI helper how you like things done. It saves you from explaining the same preferences each time.
For example, your note might say that every product comparison should show the total price with delivery and should never guess a value that the shop does not provide.
