Generate a complete HTML-slide Design System markdown file from a reference URL. Studies the page's color palette, typography, logo, and aesthetic mood, then writes a Design System that bakes in proven engineering rules (1280×720 fit contract, three-layer overflow safety net, single-absorber rule, mobile inline-flex trap catch-all, flip-card mobile fix, logo-as-SVG-symbol-with-currentColor pattern, 12px readability floor) while letting the brand identity drive the visuals. Use this whenever the user gives you a URL and asks to "build a design system from this site," "extract a design system from", "make slides like this brand," "skin slides to match this site's visual language," or wants to author HTML slides in the visual language of any specific website. Also use when the user names a brand site as a slide-deck reference, even if they don't say "design system" explicitly.
Claude Skills are markdown + scripts loaded into Claude Code; scanned with the same pipeline.
We found this by crawling public sources and nobody has attested to it. That is how most of the registry gets here, and it is not a mark against the artifact — it only means no authenticated act of publication is on record. An artifact can be the vendor's own and still appear here.
Claude Skills install to a single target, no runtime picker.
nerlo install -- seacen/deckify
Manual alternative: copy the skill folder into ~/.claude/skills/ so Claude Code loads it on next launch.
cp -r -- seacen/deckify ~/.claude/skills/
Install respects the composite badge: Clean proceeds, Caution prompts for confirmation, and Flagged is refused. Write operations require an API token.
4 of 11 scanners examined this package. The rest do not apply to it — language, ecosystem and packaging decide which analyzers can say anything, and a scanner that cannot examine an artifact reports nothing rather than passing it.

Findings in files this artifact installs stand as reported; a model re-read the rest and said which ones it believes are false positives. This is a second opinion published beside the evidence, not a correction to it: the per-scanner reports above are unchanged, every dismissed finding is still listed there at its original severity, and the score and the Flagged badge are computed from those raw severities alone. Nothing below moved them.
This review has not run for this scan yet. It runs once per scan, in the background, and is kept; it appears here when it has. Until then all 50 findings above stand exactly as their scanners reported them, at full severity.
