replit-deck Single-file horizontal-swipe HTML deck in the style of Replit Slides's landing-page template gallery. Eight distinct themes (helix, holm, vance, bevel, world-dark, world-mint, atlas, bluehouse) — each a complete visual system (palette + type + accent) captured from replit.com/slides. Pick one theme, do not mix. For pitch decks, board reports, brand memos, campaign reveals — when the user explicitly wants "Replit Slides style".

Replit Deck Skill

Produce a single-file horizontal-swipe HTML deck in one of eight Replit-Slides themes. Every theme is a complete visual system — do not mix tokens across themes.

Workflow

Step 0 — Pre-flight (mandatory reads)

  1. Read assets/template.html end-to-end. The [data-theme] blocks carry the tokens; the <script> at the bottom solves five iframe nav bugs — do not rewrite it.
  2. Read references/themes.md → pick one theme that matches the user's brief. If the user already picked a theme via od.inputs.theme, use that.
  3. Read references/layouts.md → you'll copy <section> blocks from here.
  4. Read references/checklist.md → P0 must pass before emit.

Step 1 — Commit to one theme

Write out loud (in the TodoWrite or plan section) which theme and why. Once picked, every slide uses that theme's tokens only. No swapping mid-deck. The <body data-theme="helix"> attribute is the single source of truth.

Theme Pick when
helix SaaS board update, product metrics, neutral modern
holm Legal memo, investor pre-read, serious / institutional
vance Art portfolio, design catalog, photographer / sculptor
bevel Fashion campaign, lookbook, Y2K / editorial attitude
world-dark Policy report, finance analysis, premium dark
world-mint Lighter companion of world-dark — ESG, wellness finance, sustainability
atlas Long-form narrative, chapter deck, museum / archive aesthetic
bluehouse Consumer product, real estate, lifestyle, colorful cards

Step 2 — Plan slide rhythm before writing HTML

Default 6 slides. Write the rhythm BEFORE any HTML, for example (helix, 6 slides):

01  cover           hero + title + subtitle
02  kpi-row-6       6 metrics with ▲/▼ deltas
03  split-insight   left stat + right paragraph
04  chapter-plate   section divider
05  three-up        three parallel columns
06  closing         one bold number or CTA

Show this to the user. Redirecting at this stage is cheap.

Step 3 — Copy seed, bind theme

  1. Copy assets/template.html to project root as index.html.
  2. Set <body data-theme="<chosen>">.
  3. Replace <title>.
  4. Delete the placeholder slides in the body (the seed ships with 3 demo slides). Keep the chrome (counter / progress / hint).

Step 4 — Paste layouts, fill real copy

For each planned slide, copy the matching <section> from references/layouts.md. Replace every [REPLACE] with specific copy — never leave placeholders, never use lorem. If a slide feels empty, pick a different layout.

Tag each slide with data-screen-label="01 Cover", "02 Metrics", etc., in presentation order.

Step 5 — Self-check

Run references/checklist.md silently before emit: the P0 theme-lock gate plus the five-dimension 15 critique (Philosophy / Hierarchy / Execution / Specificity / Restraint). Any dimension ≤ 3 → re-do before emit.

The P0 theme-lock grep is non-negotiable:

grep -E 'data-theme|style="--' index.html | head

If any style="--accent:..." or theme override appears on individual slides, revert. One theme per deck.

Step 6 — Emit artifact

<artifact identifier="deck-<slug>" type="text/html" title="<Deck title>">
<!doctype html>
<html>...</html>
</artifact>

One sentence before the artifact. Stop after </artifact>.

Hard rules

  • One theme per deck. data-theme set on <body> — never override per-slide.
  • Numbers are real or absent. No invented metrics. Use or a grey block as an honest placeholder.
  • Display face follows theme. helix/world-dark/world-mint/bluehouse use the sans Display; holm/vance/atlas use the serif Display; bevel uses the Y2K display. Do not swap. (Authoritative source: the --font-display token of each theme in assets/template.html — if this list ever disagrees with the template, the template wins.)
  • Accent appears 12× per slide max. Never a gradient-spam.
  • Never rewrite the nav script. Five iframe bugs it solves are not obvious.
  • Keep it one HTML file. Inline all CSS. No external fonts — the system stack in each theme is deliberate.
  • data-screen-label on every slide.
  • No Replit logo / brand lockup. These are template styles, not a Replit-brand deck.

When to pick replit-deck vs. peer skills

Skill Pick when
simple-deck Plain, single-theme deck bound to the project's DESIGN.md tokens. When the deck should match the host brand, not assert its own. (designSystemRequired: true.)
magazine-web-ppt Editorial "magazine × e-ink" aesthetic (WebGL fluid background, serif titles, chapter plates). When the brief asks for a keynote / launch / sharing-style deck and calls out Monocle / WIRED / Kinfolk / Domus.
replit-deck The brief explicitly asks for Replit-Slides gallery aesthetic, or needs one of the 8 token-frozen visual identities (SaaS board, editorial memo, gallery catalog, Y2K campaign, policy report, museum chapter, consumer cards). No dependency on DESIGN.md.

If the user just says "make me a deck" without further guidance, default to simple-deck — it respects their design system. Pick replit-deck only when the brief is explicit about the aesthetic or names a theme.


Scope & provenance

  • Eight themes = the full replit.com/slides landing-page gallery at the time of snapshot. Not a curated subset — every theme card currently published on replit.com/slides is represented here (helix, holm, vance, bevel, world-dark, world-mint, atlas, bluehouse). If Replit ships a ninth template, it is not automatically reflected in this skill.
  • Snapshot date: 2026-04-29. All hex values were sampled from the actual replit.com/slides PNGs on that date with ImageMagick — no guessed colors, no memory substitutions. See references/themes.mdContributing a new theme for the exact sampling procedure.
  • Maintenance: one-time snapshot, not tracked. Replit Slides is a live product and may drift. This skill does not auto-sync. If you notice Replit has updated colors or added a theme and want it reflected here, open an issue on nexu-io/open-design titled replit-deck: re-sync to replit.com/slides (YYYY-MM-DD) and attach the updated screenshots. There is no designated owner monitoring the upstream.
  • No Replit branding. These are gallery-style templates, not a Replit-brand deck. The checklist (P0) forbids inserting a Replit logo or wordmark.

Browser / runtime support

  • Target: modern evergreen desktop browsers (Chrome 110+ / Safari 16+ / Firefox 115+) and modern mobile Safari / Chrome.
  • Features used: CSS scroll-snap (horizontal), color-mix(), CSS custom properties, text-wrap: balance. All ≥ 93% Baseline.
  • Not supported: IE 11, Safari < 15, any browser without color-mix() (would need a fallback --accent-soft if you want to support older Safari; out of scope for this skill).
  • Mobile: horizontal scroll-snap works on iOS Safari 16+ and Android Chrome. Keyboard nav is desktop-only by design.
  • Nav script behavior: reused verbatim from skills/simple-deck — survives iframe embedding (the daemon preview surface), dual listener races, focus loss, and position persistence across reloads. Do not rewrite it.

Verification

The skill auto-registers with the daemon on filesystem scan (no manual wiring). Confirmed against a running daemon on localhost:7456 after adding this skill:

$ curl -s localhost:7456/api/skills \
    | node -e "const d=JSON.parse(require('fs').readFileSync(0,'utf-8')); \
               console.log(JSON.stringify(d.skills.find(s=>s.id==='replit-deck'), null, 2));"
