Before / after

Same standard brief both times: a landing page for Tally, a fictional budgeting app, screenshotted at 1440px. Before = no skill. After = generated by us applying the skill's published instructions to that brief. We did not run the skill inside its own agent or tooling, so results may differ from a native install. How we test

Before: Tally landing page without any skill — Before (no skill)

After: Tally landing page with claude-design-system-prompt — After (with claude-design-system-prompt)
