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.
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.
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.
Read references/layouts.md → you'll copy <section> blocks from here.
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
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
Copy assets/template.html to project root as index.html.
Set <body data-theme="<chosen>">.
Replace <title>.
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 1–5 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.
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 1–2× 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.md → Contributing 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 design-templates/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 design template auto-registers with the daemon on filesystem scan (no manual wiring). Confirmed against a running daemon on localhost:7456 after adding this template:
All four example decks (examples/example-{helix,holm,atlas,bluehouse}.html) open directly in a browser. Keyboard nav (← / → / Space / Home / End) and horizontal scroll-snap work in Chrome 129 and Safari 18.
