Open Design → Open Slide Template Production

Overview

This skill captures a practical workflow: use Open Design as a visual template corpus, then rebuild the result as Open Slide React slides.

Core rule: Open Design is a source of design language, not a runtime dependency. Mine its palettes, typography, page recipes, examples, and component rhythm; implement the output as Open Slide Page[] with React primitives.

This skill also bundles a ready-to-copy asset pack at templates/open-slide-template-pack/: 49 decks, 867 pages = 11 Open-Slide official/starter decks + 38 Open-Design-derived suites.

Quality baseline:

• Treat original Open-Slide official examples as the stronger visual baseline.
• Treat OD-derived suites as supplemental style expansion, not the flagship standard.
• When improving OD suites, compare them against official Open-Slide examples before shipping.

Open-Slide Official Baseline Inventory

The playground includes 11 official/starter Open-Slide decks. Use these as the first reference set when judging layout, motion, hierarchy, and polish.

Official/starter total: 11 decks, 107 pages.

Bundled template pack inventory: 49 decks, 867 pages = 11 official/starter decks + 38 standalone OD suites.

Local playground inventory may include extra kit/demo decks, but the public skill pack intentionally ships only the clean 49-deck template set.

When to Use

Use this skill when you need to:

• Convert Open Design examples or design systems into Open Slide decks.
• Create an OD-derived template kit, suite, album, or gallery.
• Expand a small template suite into a reusable 20-page presentation pack.
• Build public-facing React slide templates with screenshot QA.
• Preserve design provenance while avoiding runtime coupling.

Do not use it for:

• Importing Open Design daemon, web app, agent adapter, or navigation runtime.
• Copying raw single-file HTML decks directly into Open Slide.
• Producing .pptx files.
• Shipping public repos without credential and path audits.

Architecture Decision

Standard 20-Page Suite Structure

For OD-derived template suites, use this stable 20-page shape:

1. Cover
2. Agenda
3. Problem / Context
4. Framework
5. Content
6. Metrics / Data
7. Timeline / Roadmap
8. Diagram / Architecture
9. Closing / CTA
10. Section Divider
11. Quote / Key Insight
12. Comparison
13. Process / Workflow
14. Matrix / 2×2
15. Table / Spec
16. Case Study
17. Checklist
18. Risks / Tradeoffs
19. FAQ / Appendix
20. Thank You / Contact

Important learned preference:

• Keep the first 9 pages visually stable.
• Add coverage by appending pages 10–20.
• Do not mass-rewrite many suites into heavily scene-specific layouts unless screenshots prove the result is better.

Bundled 49-Deck Asset Pack

The skill ships a complete Open Slide template pack:

open-design-to-open-slide/templates/open-slide-template-pack/
  manifest.json
  README.md
  slides/
    getting-started/index.tsx
    open-slide-launch/index.tsx
    ...
    od-xhs-post-suite/index.tsx

Install into any Open Slide project:

bash open-design-to-open-slide/scripts/install-template-pack.sh /path/to/open-slide-project

Install only OD-derived suites:

bash open-design-to-open-slide/scripts/install-template-pack.sh /path/to/open-slide-project --od

Install only official/starter decks:

bash open-design-to-open-slide/scripts/install-template-pack.sh /path/to/open-slide-project --official

Overwrite existing same-slug decks only when explicit:

bash open-design-to-open-slide/scripts/install-template-pack.sh /path/to/open-slide-project --overwrite

Inspect the bundled manifest:

python3 open-design-to-open-slide/scripts/list-template-pack.py

Pack rules:

• Keep slides as plain Open Slide React source under slides/<slug>/index.tsx.
• Do not include Open Design runtime code.
• Do not include local deployment output, screenshots, caches, or credentials.
• manifest.json is the count source of truth for consumers.

Workflow: Create a New OD-Derived Suite

1. Pick a slug:

mkdir -p slides/od-<name>-suite

2. Inspect Open Design source candidates:

# examples only; adapt paths to your local Open Design clone
ls skills/
ls templates/
ls design-systems/

3. Extract only:

• palette
• typography
• component shape
• visual rhythm
• page archetypes
• provenance path

4. Implement in Open Slide TSX:

import type { CSSProperties, ReactNode } from 'react';
import type { DesignSystem, Page, SlideMeta } from '@open-slide/core';

export const design: DesignSystem = { /* tokens */ };
export const meta: SlideMeta = {
  title: 'OD <Name> Suite',
  description: '<Name> OD-derived 20-page Open Slide template suite.'
};
export const notes = [
  'Source: Open Design ...',
  'Runtime: Open Slide only'
];

const Cover: Page = () => /* ... */;
// ... 20 pages total
export default [
  Cover, Agenda, Problem, Framework, Content,
  Metrics, Timeline, Diagram, Closing,
  SectionDivider, QuoteInsight, Comparison, ProcessWorkflow,
  Matrix2x2, TableSpec, CaseStudy, ChecklistPage,
  RisksTradeoffs, FAQAppendix, ThankYou
];

5. Keep design helpers local and simple:

const rgba = (h: string, a: number) => {
  const x = h.replace('#', '');
  const n = parseInt(x.length === 3 ? x.split('').map(c => c + c).join('') : x, 16);
  return `rgba(${(n >> 16) & 255}, ${(n >> 8) & 255}, ${n & 255}, ${a})`;
};

const isDarkBg = (h: string) => {
  const x = h.replace('#', '');
  const n = parseInt(x.length === 3 ? x.split('').map(c => c + c).join('') : x, 16);
  const r = (n >> 16) & 255;
  const g = (n >> 8) & 255;
  const b = n & 255;
  return (0.2126 * r + 0.7152 * g + 0.0722 * b) < 96;
};

const dark = isDarkBg(t.bg);

dark must be global if appended pages use it. Missing global dark can build successfully but render blank at runtime. Nasty little trap.

Workflow: Expand a 9-Page Suite to 20 Pages

1. Count pages:

python3 - <<'PY'
from pathlib import Path
base = Path('slides')
for p in sorted(base.glob('od-*-suite/index.tsx')):
    s = p.read_text()
    pages = s.split('export default [')[-1].split(']')[0].count(',') + 1
    print(p.parent.name, pages)
PY

2. Append pages 10–20 from the standard recipe list.
3. Update copy such as 9 slides → 20 pages.
4. Update metrics such as 9 → 20 and slides → pages.
5. Ensure appended pages only reference globally available helpers.
6. Run build and screenshot QA.

Build and Deploy

Typical Open Slide build:

pnpm install
pnpm build

For a static deployment, copy the build output to your web root. The exact path depends on your server.

Screenshot QA

For important work, screenshot every page and build contact sheets.

Minimum QA checks:

• all expected screenshots exist
• public route or local preview loads
• DOM is not empty
• no near-blank pages
• screenshot hashes are unique unless duplication is intentional
• cover sheet and full contact sheet are generated

Representative command pattern:

CHROME=${CHROME:-chromium}
OUT=/tmp/od-suite-shots
mkdir -p "$OUT"
for slug in $(find slides -maxdepth 2 -path 'slides/od-*-suite/index.tsx' -printf '%h\n' | xargs -n1 basename | sort); do
  mkdir -p "$OUT/$slug"
  for p in $(seq 1 20); do
    "$CHROME" --headless=new --no-sandbox --disable-gpu --hide-scrollbars \
      --virtual-time-budget=6500 --window-size=1920,1080 \
      --screenshot="$OUT/$slug/p${p}.png" \
      "http://127.0.0.1:5173/s/$slug?p=$p"
  done
  echo "captured $slug"
done

Use Python/Pillow to compute hashes, detect near-blank images via image variance, and generate contact sheets.

Visual Rules

1. Design for 16:9 fixed canvas.
2. One idea per page.
3. Use strong hierarchy and cards; avoid bullet dumps.
4. Use Open Design for rhythm, not runtime.
5. Keep provenance in notes or comments.
6. Strip obvious third-party logos and brand marks.
7. Avoid remote assets unless there is a strong reason.
8. Generate screenshots and contact sheets before declaring success.

Common Pitfalls

1. Copying Open Design HTML directly. This creates a hidden second runtime. Port the design into React primitives instead.

2. Missing global variables in appended pages. Pages 10–20 often reference dark, rgba, font, t, Card, Shell, Tag, H, and P. If any are scoped inside old functions, the deck may build but render blank.

3. Trusting route 200. SPA route 200 only proves index.html was served. Use browser DOM/screenshot checks to catch white screens.

4. Over-fitting each suite into scene-specific structure. Preserve visual coherence first. Expand coverage by appending reusable pages.

5. Huge screenshot jobs with no progress. Use background execution and print progress per suite.

6. Dismissing duplicate hashes. Duplicate hashes may mean actual white screens. Check variance and DOM.

7. Leaking local paths or internal URLs in public docs. Public skills should use placeholders and environment variables.

Verification Checklist

• Every suite exports the intended number of pages.
• pnpm build passes.
• Preview route opens in a browser.
• Screenshots cover every suite/page.
• Screenshot hash count equals screenshot count unless duplication is intentional.
• No near-blank pages by variance check.
• Contact sheet generated.
• Public version contains no secrets, private IDs, or machine-specific absolute paths.
• templates/open-slide-template-pack/manifest.json reports 49 decks.
• scripts/install-template-pack.sh copies decks into a clean Open Slide project.
