When to Use

Use to catch AI-generated UI that "looks off", is misaligned or centered-mush, or fails usability — when you need reproducible spatial measurements and an evidence-based usability review. Metrics do not prove user success, accessibility or overall design quality. Compose it with any taste/token design skill before reporting design "done".

deterministic-design

Thesis: determinism beats AI randomness. A model can't trust its own eye on layout — so don't. Render the UI and measure it.

Two sub-skills (load as needed):

  • design-spatial — deterministic layout audit: explicit grid
    • 8-pt spacing, and layout-audit.js computes centroid / optical-center / pixel-oracle balance and draws an annotated screenshot. Numbers, not vibes. Plus a render-then- critique vision loop.
  • design-ux — usability audit: scores the rendered UI against Nielsen's 10 + interaction heuristics via an authorized separate judge or clearly disclosed self-review → prioritized fix list.
