One of 6 test cases the skill fixed. Same model, same prompt, with and without the skill.
I'd like to convert my founder's reflection essay on building resilient organizations into an HTML slide deck. It should have a warm, calm, literary visual tone suitable for longform editorial thought leadership. Provide slides for the introduction, four core reflections, and a concluding thought. Wrap the final result in an artifact wrapper.

The instructions your model reads when the skill loads.
Deep navy canvas with warm-yellow italic Cormorant serifs and a single dusty teal accent. A quiet, scholarly aesthetic.
A single self-contained HTML deck — typography, palette, decorative system, and slide vocabulary are all tuned together. Mixing layouts across templates breaks the system; stay inside this one.
Anything that should feel scholarly, literary, and quietly intelligent: research synthesis, white papers, academic and policy briefs, advisory deliverables, longform editorial pieces, founder reflections. Equally strong for any deck — including tech, business, or creator work — that wants a calm, considered atmosphere instead of energetic visuals.
Contexts that need visual heat or pop — the navy + warm-yellow italic-Cormorant aesthetic is intentionally low-tempo.
