Slide Deck skill

/slide-deck — Draft, update, convert, and export branded React decks

Authors React/TypeScript decks for ${SLIDE_DECK_REPO:-$HOME/code/your-slide-deck-site}/src/app/slides/<slug>/page.tsx using the user's slide system. Branded output (no separate HTML pipeline) — when portable HTML/PDF is needed, export mode snapshots the rendered React deck via Playwright so the output is brand-perfect.

Modes (pick one before Step 1)

Mode	Invocation	Goal
new	/slide-deck new <topic> (default)	Draft a new deck from a brief
update	/slide-deck update <slug>	Modify an existing deck (with overflow guards)
ppt	/slide-deck ppt <path-to-pptx>	Convert a legacy PPTX into a React deck
export	/slide-deck export <slug> [html|pdf|vercel]	Snapshot a deck to HTML, PDF, or Vercel URL

For update, ppt, and export, skip to the corresponding mode section below. For new, continue through Steps 1–8.

---

Step 1 — Capture the brief (ask all at once)

Ask in one structured message. Don't round-trip on each.

1. Topic / title — what's the deck about?
2. Audience — who's in the room? (technical / executive / mixed / clients) Push for specificity: "founders" is too broad; "B2B SaaS founders at MicroConf" is workable.
3. Length — rough slide count: 5–10 (lightning / short internal) / 10–15 (short keynote, pitch) / 20–25 (keynote) / 30+ (workshop — uncommon for branded decks).
4. Density — speaker-led (1 idea/slide, big type, lots of breathing room, more slides if needed) or reading-first (4–6 bullets/slide, structured grids, self-contained for async review).
5. CTA — what should the audience do/think/feel after?
6. Slug — kebab-case (e.g., marketing-like-an-engineer).
7. Content state — all content ready / rough notes / topic only.

Remember density — it affects slide count, copy length per slide, and which primitives to favor. See references/narrative-and-voice.md for the density-specific rules.

Step 2 — Three narrative angles

Riff on zarazhangrui/frontend-slides' "show, don't tell" — but applied to story, not visuals (your visual system is fixed).

Pitch 3 angles in 1–2 sentences each:

• Safe — most likely to land. Conventional structure for the audience.
• Bold — contrarian or counterintuitive frame. Higher upside, slight risk.
• Wildcard — unexpected structure (story-first, single-question deck, anti-thesis, etc.).

The user picks one. If they reject all three, propose three more — don't force a path.

Step 3 — Outline

For the chosen angle:

1. Sections — propose 3–7 named sections (e.g., Title, Hook, Problem, Framework, Examples, Close). The default 3-act structure is OPTIONAL; only use it if the user wants it or the deck is a keynote-length talk that benefits from one.
2. Slide titles within each section
3. One-line takeaway per slide

Total slide count should match the duration estimate from Step 1.

Show the outline as a table. the user edits / approves before expand.

Step 4 — Expand to slide content

For each slide, write the full content using the user's primitives. Reference references/system.md for the primitive vocabulary and references/narrative-and-voice.md for hook patterns and voice rules.

Slide types and which primitives fit:

Slide type	Primitives	Pattern
Title	Eyebrow + <h1> with <Accent> keyword	First slide, sets brand and topic
Hook	Heading + Body	A take, story open, contrarian frame, or specific stat
Section divider	Eyebrow + Heading (centered, large)	Clean break between sections
Framework	Heading + BulletList or custom layout	The thing the user's teaching
Two-column	TwoCol	Comparison, before/after, problem/solution
Quote / pull-quote	Body (large)	Authority or audience-recognition moment
Resource / link	Body + URL on its own line	Outbound (rare — the user's voice says minimize)
Close / CTA	Heading + Body + BulletList for next steps	What the audience should do

Voice anchors — write for the ear, not the page (see narrative-and-voice.md for full rules):

• Decks are spoken aloud. Slide text + speaker notes both get said out loud. Write as you'd talk.
• Read every slide out loud before saving. If you stumble, if it sounds like a press release, rewrite.
• Contractions everywhere (don't, won't, you're, I'd). Strip them only on reading-first decks.
• "You" — never "the audience," "users," "people."
• Numbers said naturally ("a quarter" not "23.7%").
• Conviction-coded, listener-perspective, short sentences, specific nouns.
• No filler ("Today I want to talk about…") — open with a take.
• (Reading-first density mode exception: written voice is fine since no one will speak the slides — see narrative-and-voice.md.)

Step 5 — Speaker notes

Every slide gets 3–5 notes lines. Notes are the full spoken talk — write them the way you'd actually say them, pauses and asides included. Slide text is the headline; notes are the full thought.

Notes structure:

1. The opener — what you say when the slide comes up
2. The point — the one idea this slide is making
3. The supporting beat — example, data, or color
4. The transition — how this connects to the next slide
5. (Optional) The aside — a quip or callback

For title slides and section dividers, 2–3 notes is fine.

Step 6 — Generate files

Write to ${SLIDE_DECK_REPO:-$HOME/code/your-slide-deck-site}/src/app/slides/<slug>/:

1. layout.tsx — Next.js layout with <title> metadata (use the deck title)
2. page.tsx — the slide deck

Use the templates in references/template.md as the skeleton.

The <AUTHOR_HANDLE> / <AUTHOR_SITE> tokens (close-slide footer) come from ${MAKERSKILLS_CONFIG:-$HOME/.config/makerskills}/slide-deck/identity.yaml (keys: handle, site) if it exists. Otherwise ask the user for their handle and site once, offer to save them there, and use those. If they don't want a footer, drop the <p> entirely — never ship a deck with someone else's identity on it.

page.tsx must:

• Have "use client" at the top
• Import SlideDeck and Slide type from @/components/slides/slide-deck
• Import SectionRange from @/components/slides/sections (only if using sections)
• Import the primitives the user uses from @/components/slides/slide-primitives
• Declare const slides: Slide[] = [...]
• (Optional) Declare const sections: SectionRange[] = [...] with 0-indexed from/to
• Export default a component that returns <SlideDeck slides={slides} sections={sections} />

Step 7 — Preview

After writing the files, check if your slide-deck dev server is running.

lsof -i :3000-3099 2>/dev/null | grep -E "LISTEN" | head

If a port is in use (portless-compatible — check package.json for the dev script naming):

# Suggested URL pattern
echo "Preview at: http://${SLIDE_DECK_DEV_HOST:-localhost:3000}/slides/<slug>"

If no dev server is running, tell the user:

cd ${SLIDE_DECK_REPO:-$HOME/code/your-slide-deck-site} && npm run dev
# then visit http://${SLIDE_DECK_DEV_HOST:-localhost:3000}/slides/<slug>

Don't auto-start the dev server (might disrupt other work).

Step 8 — Archive

The archive lives in ${MAKERSKILLS_CONFIG:-$HOME/.config/makerskills}/slide-deck/archive/ (create the directory if missing). Never write the archive inside the skill's own folder — skill installs and upgrades re-sync from source and wipe anything saved there. Migration: if this skill's folder contains an old references/decks-archive.md with user entries, move it to <archive dir>/INDEX.md first.

Append a one-liner to <archive dir>/INDEX.md (create if missing):

- 2026-06-17 — [<title>](${SLIDE_DECK_REPO:-$HOME/code/your-slide-deck-site}/src/app/slides/<slug>/page.tsx) — <audience> — <one-line angle>

This compounds — future decks can grep "what talks have I done about X" to avoid repetition and find reusable patterns.

Mode: update

Modify an existing deck without breaking it. Risks: overflowing slides, exceeding density limits, breaking the section ranges.

Before modifying, check:

1. Read the existing page.tsx
2. Count slides + identify the section ranges
3. For each modification, apply the right guard:

Change	Guard
Adding bullets	Max 6 per BulletList in reading-first; 3 in speaker-led. If exceeded → split into two slides.
Adding text	If <Body> paragraph >2 sentences in speaker-led → split. >5 sentences in reading-first → split.
Adding images	Images must fit in the 1920×1080 stage. If the slide already has heavy content, move image to its own slide.
Adding slides	Update sections array — increment from/to for all sections after the insertion point.
Removing slides	Decrement from/to for sections after the removal. Watch for orphaned id references.
Rewriting a slide	Preserve the id (used for anchors). Only change content and notes.

After modifying:

• Re-count slides and verify section ranges sum correctly
• Spot-check the visual in the dev server before committing

Mode: ppt

Convert a legacy PPTX (client deck, conference template) into the user's React system.

1. Extract content via python3 and python-pptx:

   pip install python-pptx 2>/dev/null
   python3 -c "
   from pptx import Presentation
   import json, sys
   p = Presentation(sys.argv[1])
   out = []
   for i, s in enumerate(p.slides):
       title = next((sh.text for sh in s.shapes if sh.has_text_frame and sh.shapes_element.tag.endswith('}sp') == False), '')
       texts = [sh.text for sh in s.shapes if sh.has_text_frame]
       notes = s.notes_slide.notes_text_frame.text if s.has_notes_slide else ''
       out.append({'i': i, 'texts': texts, 'notes': notes})
   print(json.dumps(out, indent=2))
   " "<path-to-pptx>"
   

   See references/ppt-conversion.md for the full extraction + mapping recipe.

2. Show the user the extracted summary — slide titles, content excerpts, image count. Confirm before proceeding.

3. Map to React primitives:

   • First slide → title pattern (Eyebrow + h1 + Accent)
   • Content slides with bullets → Heading + BulletList
   • Comparison slides → TwoCol
   • Section breaks (title-only slides in PPTX) → section divider pattern
   • Speaker notes from PPTX → notes array on each slide

4. Images — copy referenced images from PPTX assets to ${SLIDE_DECK_REPO:-$HOME/code/your-slide-deck-site}/public/slide-assets/<slug>/, reference them in slides via <img src="/slide-assets/<slug>/<filename>" /> inside the content.

5. Write page.tsx + layout.tsx per the new-deck flow (Step 6).

6. Preserve the original PPTX — never modify in place. Save under ~/Documents/slide-conversions/<slug>-from-pptx/ with the original file + extracted JSON for audit.

Mode: export

Snapshot a deck rendered in your slide-site dev server to portable HTML / PDF / Vercel URL. Output is brand-perfect because it's screenshots of your actual rendered React deck.

Output options:

• html — standalone HTML file with snapshots as inline <img>, keyboard nav (arrow keys) baked in
• pdf — combined slide snapshots
• vercel — push standalone HTML to a Vercel project for a shareable URL

Flow (full details in references/export.md):

1. Verify dev server: confirm ${SLIDE_DECK_DEV_HOST:-localhost:3000}/slides/<slug> loads. If not, prompt the user to cd ${SLIDE_DECK_REPO:-$HOME/code/your-slide-deck-site} && npm run dev.
2. Count slides: read page.tsx, count entries in the slides array.
3. Run Playwright snapshot:

   bash references/export.md script: snapshot-deck <slug> <count>
   

   • Launches headless Chromium at 1920×1080
   • Loads http://${SLIDE_DECK_DEV_HOST:-localhost:3000}/slides/<slug>?present=1 (presenter mode hides chrome)
   • Sets localStorage["slides:/slides/<slug>"] = "0" to start at slide 0
   • Loops: screenshot → keyboard ArrowRight → wait — for N slides
   • Saves PNGs to ~/Documents/slide-exports/<slug>-<YYYY-MM-DD>/slide-<n>.png
4. Combine per output type:
   • html → wrap snapshots in a minimal HTML shell with arrow-key navigation
   • pdf → use magick (ImageMagick) or img2pdf to combine PNGs
   • vercel → vercel deploy ~/Documents/slide-exports/<slug>-<date>/
5. Report path / URL.

Caveats (mention to the user):

• Animations and presenter view are not preserved — exports are static snapshots.
• For interactive demo, present the React version live; for sharing/PDF/portable, use exports.
• Snapshots are 1920×1080 — high-quality on any device, but file size scales with slide count.

Composes with

• business-brainstorm — if a pitch deck, brainstorm the offer first; deck draws from the brief
• decide — for talks that hinge on a decision (e.g., "should I take VC money?"), /decide first
• deep-research — for talks needing data the deck doesn't have yet
• second-brain — pull relevant [[wiki]] pages as content sources; the deck can cite them
• watch-video — turn a podcast episode, Loom, or talk recording into a deck outline (run in visual mode to also capture key moments + slides shown)
• jab-hook — once delivered, the talk becomes promo angles for the BIP rotation
• frontend-skills (external) — for non-branded HTML decks where your React deck repo isn't the home

Notes on quality

• Show, don't tell — applied to narrative. Present 3 different angles for the deck (not one polished draft); let the user pick. Committing to a narrative before the alternatives are surfaced produces decks that are workmanlike, not memorable.
• Density modes matter more than aesthetic. A speaker-led deck has 3-word slides and 5-line speaker notes. A reading-first deck (leave-behind, async) reverses it. Same content, opposite artifact. Ask which mode before drafting.
• Slide text is abbreviated spoken. Both pass the read-aloud test. If a slide reads like a memo, it's wrong. If speaker notes read like slides, they're wrong.
• Overflow guards on update mode. Don't blindly cram more content into an existing slide — if the addition tips the slide over its target word count or line count, propose splitting the slide or trimming existing content. Silently overflowing produces cramped decks.
• Presenter-view stripped for exports. Playwright snapshots the ?present=0 mode so the export is clean. Never export the presenter view.
• Brand-perfect > portable. The React deck is the source of truth. HTML/PDF/Vercel exports are snapshots for sharing — animations, interactions, presenter view live only in the React version.
• 1920×1080 default, 1280×720 for previews. Full-res snapshots run 30-50 MB for a 20-slide deck; low-res halves that at minimal visual loss.
• Deploy is a real-money operation. Export mode's vercel path prompts before deploying. Auto-renew is on for domains + Vercel projects.
