dev-3.0

Drive and visually QA the dev-3.0 UI in a real browser (headless Chromium via agent-browser). Use when verifying a UI/UX change, reproducing a visual bug, taking screenshots of the running app, or self-QA before review. Triggers — "check the UI", "screenshot the app", "does this render", "QA this screen", "verify the UI change in a browser", "drive the app".

Create the initial Product UX Bible for an existing web or full-screen web app by deeply auditing the repository, using sub-agents when available, and generating docs/ux manifests, schemas, budgets, surface maps, action taxonomy, and design-token policies from observed code.

Principal UX architect skill for planning UI features before implementation. Reads and maintains docs/ux manifests, classifies the feature, decides placement, navigation, action hierarchy, design-token roles, accessibility, states, responsive behavior, and produces a precise implementation brief without coding unless explicitly asked.
