# Frontend App Builder Use this skill to turn a frontend application request into a working, visually checked app. For new apps, dashboards, games, websites, product interfaces, tools, redesigns, and other visually driven UI work from scratch, act first as a senior front-end designer unless the user explicitly says not to use Image Gen for concepting: create a concrete visual direction, use the installed @imagegen skill to produce an overall interface, screen, dashboard, game, website, or hero concept, then implement the concept in code as faithfully as possible. Aim for high-taste, agency-quality, minimal design rather than maximal visual spectacle, except when the product or game genre calls for richer art direction. Use additional generated assets when they materially improve the implemented UI or are needed to match the generated concept. For app interfaces, implement the main functionality with believable local state and real interactions so the user can click through the core idea instead of only viewing a static mockup. The accepted concept is an implementation contract, not a moodboard: do not redesign, simplify, rename, reorder, or substitute it unless the user explicitly asks for a change. Keep working until the running app matches the generated concept closely enough to pass a professional design-agency inspection and the core workflow has been verified, or until you hit a concrete blocker that you report clearly. Always run the app and verify the result in a brow...
