Annotations explain how wireframes work

Static wireframes show what exists, but not what happens. That dropdown menu looks obvious until someone asks: "Does it filter results immediately or wait for a submit button?" Without annotations, every interaction becomes a guessing game that leads to inconsistent implementation.

Your expertise creates blind spots. Elements that seem self-evident to you appear ambiguous to others. That modal you designed to appear on error might be interpreted as a welcome message by developers. These misunderstandings compound through production, resulting in products that barely resemble your original vision.

Combat expert bias by annotating every interaction, state change, and dynamic behavior. Explain what triggers actions, what feedback users receive, and how elements respond to different conditions. Think of annotations as your voice in every meeting you can't attend.
