Element Selector is an innovative tool designed to streamline the process of editing app UI elements by allowing users to simply click on the element they wish to modify, describe the desired changes, and have them implemented instantly by either the Assistant or Agent. This functionality eliminates the need to manually search through files or type out detailed descriptions, making it accessible and efficient for users of all skill levels. The tool works by mapping each UI component to its precise location in the codebase, providing the Agent with exact file references, style properties, and associated functionalities, ensuring accurate and context-aware modifications. Currently, Element Selector is available for new JavaScript-based applications, with plans to expand support to other tech stacks and older apps in the future, promising a significant enhancement in app development and maintenance efficiency.
