slides

name: slides description: Create and manage presentation decks. Two modes - Slidev markdown (default) and "conference" hand-built HTML. Use when user asks to "create slides", "make a presentation", "add slides to this project", "set up a slide deck", or mentions "slidev", "pitch deck", "conference talk", "conference deck", or "slides folder".

Slides

Scaffold and manage presentation decks in any project. Two modes:

• Slidev mode (default) - Markdown-driven decks using @slidev/cli. Best for project pitches, internal decks, README-driven content, and anything where the author edits markdown and lets Slidev render. Covered in the "Slidev Mode" section below.
• Conference mode - Hand-built HTML deck modelled on the AI Native DevCon London 2026 talk. Dark theme, Inter + JetBrains Mono, right-arrow progressive reveal, fullscreen, page number, in-deck notes overlay, separate teleprompter sheet for a phone, deployable to GitHub Pages via a gh-pages worktree. No framework, no build step - the author edits HTML directly. Covered in the "Conference Mode" section further below.

0. Ask which mode

When the user invokes the skill, ASK upfront:

"Slidev (default) or conference (hand-built HTML)?"

Pick by signal too. Default to Slidev unless the user says any of: "conference", "conference talk", "conference deck", "hand-built", "no framework", "html deck", or references the AI Native DevCon style. If they pick conference, skip the Slidev sections and follow "Conference Mode" below.

Slidev Mode

1. Ask where to keep slides

Ask the user where to create the slides folder. Suggest ./slides as default.

2. Scaffold the folder

Create the following structure:

<slides-dir>/
├── slides.md       # Slide content (Slidev markdown)
├── package.json    # Slidev dependencies
├── Makefile        # Convenience targets
└── public/         # Static assets (images, diagrams)

package.json

{
  "name": "slides",
  "private": true,
  "scripts": {
    "dev": "slidev slides.md --open",
    "build": "slidev build slides.md",
    "export": "slidev export slides.md"
  },
  "dependencies": {
    "@slidev/cli": "^52.11.5",
    "@slidev/theme-default": "^0.25.0"
  }
}

Makefile

.PHONY: slides slides-build slides-export slides-setup

slides: node_modules ## Open slides in browser with hot-reload
    npx slidev slides.md --open

slides-build: node_modules ## Build static SPA to ./dist
    npx slidev build slides.md

slides-export: node_modules ## Export slides to PDF
    npx slidev export slides.md

slides-setup: ## Install dependencies
    npm install

node_modules: package.json
    npm install
    @touch node_modules

slides.md (starter)

Generate a title slide using the project name. Use this template:

---
theme: default
title: "<Project Name>"
---

# <Project Name>

<One-line project description from README or user prompt.>

---

# Overview

- Point one
- Point two
- Point three

3. Install dependencies

Run npm install inside the slides folder.

4. Add to .gitignore

If a .gitignore exists in the slides folder or project root, ensure node_modules/ and dist/ are ignored. Check before adding to avoid duplicates.

Content Generation

When asked to generate or write slide content:

1. Read the source material (README, docs, solution.md, or user prompt)
2. Write slides in Slidev markdown format:
   • --- separates slides
   • YAML frontmatter on first slide sets theme and title
   • Standard markdown for content (headers, lists, code blocks, images)
   • Images go in public/ and are referenced as /image.png
3. Keep slides concise — one idea per slide, max 5-6 bullet points
4. Write directly to slides.md

Slidev Markdown Quick Reference

---
theme: default
title: "Deck Title"
---

# Slide Title

Regular markdown content.

---

# Code Slide

\`\`\`python
def hello():
    print("hello")
\`\`\`

---

# Image Slide

<img src="/diagram.png" class="h-80" />

---
layout: two-cols
---

# Left Column

Content here.

::right::

# Right Column

Content here.

---
layout: center
---

# Centered Content

Big statement.

Available Layouts

• default — standard content
• center — centered on page
• two-cols — split with ::right:: separator
• image-right / image-left — content + image side by side
• cover — title/cover slide
• section — section divider

Styling

Keep slides.md readable. Prefer built-in layouts and theme classes before writing custom CSS. Add styles selectively — not preemptively.

Content first, styling after. When a slide does need a <style> or <style scoped> block, put it at the bottom of the slide, just above the closing ---. Slidev parses the whole slide regardless of position, so pushing CSS below the content means a reader opening slides.md sees the actual content first — if they then scroll past some styling, so be it.

If a pattern is reused across many slides (typography, card layouts, shared tables), promote it to the theme under themes/<name>/styles/ instead of repeating it inline.

Revision

When asked to edit slides:

1. Read slides.md
2. Make targeted edits — don't regenerate the whole deck
3. Suggest make slides to preview changes

Themes

By default, use theme: default in frontmatter. Do NOT suggest or apply custom themes unless the user specifically asks about available themes.

Custom themes are local Slidev theme folders stored in this skill at themes/<name>/. To apply one, copy the theme folder into the slides directory and set theme: ./<name> in frontmatter.

Available Themes

qblabs

Style inspired by QuantumBlack's publicly available visual identity. All colors, fonts, and design patterns sourced exclusively from public materials:

• quantumblack.com — public website (redirects to mckinsey.com/capabilities/quantumblack)
• github.com/mckinsey/qbstyles — matplotlib theme, dark bg #0C1C23
• brandfetch.com/mckinsey.com — public brand colors

Setup: Copy themes/qblabs/ into the slides directory, then:

---
theme: ./qblabs
title: "Deck Title"
---

Layouts:

• cover — dark navy background, blue accent bar, centered title
• default — clean white background, blue underline on h1
• section — dark navy section divider with blue accent

Key colors (from public QB website/branding):

• #051C2C — Dark navy (hero/section backgrounds)
• #2251FF — Electric blue (accent, links, CTAs)
• #222222 — Body text (on light backgrounds)
• #A2AAAD — Secondary text (medium grey)

Fonts: Georgia (serif, headings) and Arial (sans, body) — standard PowerPoint substitutes for Bower and McKinsey Sans which are not publicly licensed.

Utility classes: .qb-blue, .qb-navy, .qb-bg-dark, .qb-bg-light, .qb-accent-bar

Conference Mode

A hand-built HTML conference deck. No framework, no Vue, no Slidev, no build step. The author edits presentation.html directly. Speaker notes live in presentation.md and are baked into a standalone notes.html teleprompter sheet for a phone or second screen.

When to use it

• A conference talk (20-45 minutes) where presence and feel matter as much as content.
• Dark theme, typographic, whitespace-led, minimal chrome.
• Custom interactions (right-arrow progressive reveal, hidden in-deck notes overlay, fullscreen toggle).
• Deploys to GitHub Pages via a gh-pages worktree, with separate public URLs for the deck and for the phone-readable notes sheet.

If the user wants a quick scaffold from a README, or wants Markdown-driven content with Slidev's built-in layouts, use Slidev mode instead.

Setup flow

1. Ask where to keep the deck. Suggest ./presentation or a conference-specific folder name (for example ./conferences/<year>-<event>/).
2. Copy everything under themes/conference/template/ into the target folder verbatim. No npm install, no dependencies.
3. Tell the user:
   • make dev serves presentation.html on http://localhost:2663.
   • make notes serves notes.html (open on a phone for a teleprompter).
   • Edit presentation.html to change slide content.
   • Edit presentation.md to change speaker notes, then regenerate notes.html from it.
4. If the user wants make deploy to work, ask for their site repo path and the public URL pattern, then update SITE_REPO, PUBLIC_NOTES_URL, and PUBLIC_PRESENTATION_URL at the top of the Makefile.

File layout

<deck-dir>/
├── presentation.html   # The deck (single hand-edited HTML file)
├── presentation.md     # Single source of truth for speaker notes
├── notes.html          # Baked teleprompter sheet (regenerated from md)

└── README.md           # Quick start, conventions

Slide markup conventions

• Each slide is a <section class="slide <type>" data-name="<unique-id>"> block.
• Each slide uses an eyebrow + heading pattern: <div class="label-in">Section name</div> then <h3>One central idea</h3> (or <h1> for title slides, <h2> for disclaimer / punch).
• Slides that should reveal items one-at-a-time on Right have data-reveal="true" and mark each fragment with class="revealable".
• The provided slide types: title, disclaimer, content, chartslide, punch (section divider), regtable (two-column bad-vs-good table, optionally recap-hero), jokes (progressive reveal list with punchline), title split (title + image / QR on the right).

Copy conventions

• No em-dashes. Use a regular hyphen. Do not "tidy up" hyphens into em-dashes anywhere.
• No full stops at the end of slide leads or headings. Body text and notes are normal prose.
• One central idea per slide. Whitespace-led. The slide is not the script.

Colour convention

Apply consistently when colouring words, lines, table rows, and markers.

The slate accent (#5e8a9c) and warm rust (#d99161) are the deck's neutral accents - eyebrows, section punches, decorative rules.

Speaker notes flow

• presentation.md is the single source of truth for speaker notes. The deck (presentation.html) is the public artefact and should not carry full notes inline.
• Each slide in presentation.md is a ## or ### heading. On-slide content sits above ---; speaker notes sit below ---. End each notes block with *Clock: X:XX* for pacing.
• Top-level # headings in the md are the author's organising structure (parts / acts) - they are scaffolding, not slides. Skip them when regenerating.
• When notes change, regenerate notes.html by rewriting the entries inside its <div id="list"> block from the parsed md, pairing each md slide by index with the deck's data-name order. Keep the notes.html shell (CSS, controls bar, fonts / theme JS) untouched.

Deploy pattern

make deploy-presentation and make deploy-notes publish straight to the gh-pages branch of SITE_REPO via a throwaway git worktree. Each pushes a single commit. The deck lives at <site>/presentation/presentation.html; the notes sheet lives at <site>/presentation/notes.html. The phone-readable notes URL is meant to be opened on a second screen during the talk.

Example Interactions

User: "Add slides to this project"

1. Ask: "Slidev (default) or conference (hand-built HTML)?"
2. If Slidev: ask where to keep them (suggest ./slides), scaffold folder with theme: default, run npm install, tell user cd slides && make slides to open.
3. If conference: ask where to keep the deck (suggest ./presentation or ./conferences/<year>-<event>/), copy themes/conference/template/* into it, tell user make dev to open.

User: "Create a conference talk deck" or "Set up a hand-built HTML deck"

1. Skip the Slidev question - go straight to conference mode.
2. Ask where to keep the deck.
3. Copy themes/conference/template/* into the target folder.
4. Tell user: make dev to preview, edit presentation.html for content and presentation.md for notes, regenerate notes.html from md when notes change.

User: "Create slides from the README"

1. If slides folder exists, read slides.md to understand current state
2. If no slides folder, scaffold first
3. Read README.md
4. Generate slide content and write to slides.md
5. Suggest make slides to preview

User: "Add a slide about the architecture"

1. Read slides.md
2. Add new slide section with --- delimiter
3. Suggest make slides to preview

User: "What themes are available?" or "Use the qblabs theme"

1. List available themes from the Themes section above
2. If user picks one, copy the theme folder into the slides directory
3. Update frontmatter to theme: ./<name>
