UI Context for Agents

UI Context for Agents is a Chrome extension that generates prompts with UI elements and source files for coding agents.

UI Context for Agents is a Chrome extension that helps you communicate UI changes to coding agents. Instead of taking manual screenshots and guessing file locations, you click an element, drag across text, or mark a region on a page, and type your comment. The tool generates a prompt carrying the element's selector, text, classes, and on React and Vue development builds, its component chain and source file. It also captures screenshots of marked regions. You can pause animations, move elements to show repositioning, and review all comments before copying the single prompt to your clipboard for agents like Claude Code, Cursor, or Codex.
