Ask when unknown, because it decides Step 5.</li>\n<li><strong>The three messages:</strong> what the audience must remember after the deck.</li>\n<li><strong>Output format:</strong> Marp markdown unless there is a reason otherwise. A web app when the deck should run a live demo or live at a URL. A <code>.pptx</code> when the user names the file or a house template, produced by the external <code>pptx</code> skill from this skill's outline, copy, and notes. Decide now, not at Step 7: the format sets the type and notes mechanics in Steps 5 and 6.</li>\n</ul>\n<p>Route by setting:</p>\n<ul>\n<li><strong>Live talk, internal, or recorded deck</strong> → Steps 2-8 in order.</li>\n<li><strong>Investor pitch deck sent to be read</strong> → <a href=\"references/pitch-decks.md\">references/pitch-decks.md</a> first. Its 10-slide framework replaces Step 3's outline, and its async copy rules replace <code>writing-slides.md</code> at Step 4 (do not load both: their density rules contradict). Step 2 still applies in compressed form; the spine is what stops a pitch reading as a feature list. Skip Step 6. The same company pitching live on a demo-day stage is a presented deck: use the standard path with the pitch framework as its outline.</li>\n</ul>\n<h3>Steps 2-7: Build the deck</h3>\n<p>Read each step's reference when you reach it:</p>\n<table>\n<thead>\n<tr>\n<th>Step</th>\n<th>Reference</th>\n<th>Covers</th>\n</tr>\n</thead>\n<tbody>\n<tr>\n<td>2.

Primitives designed before the outline get shaped around slide 3 and fight every slide after it.</p>\n<h3>Step 8: QA pass (produces evidence)</h3>\n<p>Render the delivered format and inspect every slide. Record layout defects and measured contrast; a self-assigned glance score is editorial judgement. Keep the detailed table with the artifact when useful, and summarize material results in chat:</p>\n<pre><code>| # | Slide | 3-sec test | One message | Spine beat | Layout | Colour | Contrast |\n|---|-------|-----------|-------------|------------|--------|--------|----------|\n| 1 | Title | pass | pass | once upon a time | full statement | teal | 12.6:1 |\n</code></pre>\n<ul>\n<li><strong>3-sec test:</strong> parseable in three seconds at arm's length (Duarte's glance test). Cut copy on any failure until it passes. Pitch decks are read, not glanced: substitute \"makes sense forwarded with no context\".</li>\n<li><strong>One message:</strong> exactly one idea per slide; split slides carrying two.</li>\n<li><strong>Spine beat:</strong> which beat of the Step 2 spine this slide serves. A slide serving none is a fact you found interesting; cut it.</li>\n<li><strong>Layout:</strong> the layout should change when the slide's job changes. Flag a run of three or more identical layouts and keep it only when the section is deliberately a list.</li>\n<li><strong>Colour:</strong> the section accent, or the full-bleed palette, matching what Step 5 assigned.</li>\n<li><strong>Contrast:</strong> the smallest text on the slide against its background. 4.5:1 for body and captions, 3:1 only for text at 24px (18pt) or larger. Record the ratio, not \"ok\".</li>\n</ul>\n<p>Deck-level checks below the table:</p>\n<ul>\n<li>Every spine beat has at least one slide, and the ending matches the one written first</li>\n<li>The deck states a position a reasonable person could disagree with</li>\n<li>One colour system throughout: accents per section, or full-bleed palettes, never both</li>\n<li>Recap slide has exactly one line per core section</li>\n<li>Speaker notes sit where the output format reads them (Marp and Slidev: an HTML comment at the end of the slide; reveal.js: a <code>Note:</code> line; <code>.pptx</code>: the notes pane)</li>\n<li>Pitch decks only: 10 slides plus an appendix at most, explicit ask slide (amount and use of funds), headlines pass the forwardable test</li>\n</ul>\n<p>Fix observed defects and inspect affected slides again. If rendering is unavailable, label visual verification unrun.</p>\n<h2>Core principles</h2>\n<ul>\n<li><strong>Story before slides:</strong> the spine decides which slides exist. Write the ending first.</li>\n<li><strong>Take a position:</strong> a deck nobody could disagree with has not said anything.</li>\n<li><strong>Headlines do the work:</strong> the complete claim, not a topic label. \"Q3: revenue up 40%. Here's how.\" beats \"Q3 performance overview\".</li>\n<li><strong>Impact through scale, not weight:</strong> large light type beats small bold type.</li>\n<li><strong>One colour system, held for the whole deck:</strong> full-bleed palettes where a palette owns the entire slide, or dark with one accent per section. Either is the rhythm the audience tracks position by.</li>\n<li><strong>Demo it live where you can:</strong> a working demo on a web deck, not a screenshot of one; a recording where the demo cannot run offline.</li>\n</ul>\n<h2>Gotchas</h2>\n<ul>\n<li><strong>Dark deck in a bright room:</strong> the default dark system relies on the room. Under daylight or a weak projector the black background goes grey and white body text washes out. Ask about the venue in Step 1; take the light \"paper\" palette or a white background when the answer is bright, and test on the projector, not the laptop.</li>\n<li><strong>Contrast checked at headline size only:</strong> a saturated full-bleed pair that reads at 100px fails at 20px caption size. Check the smallest text on the slide: 4.5:1 for body and captions, 3:1 for 24px-plus text, from the actual hex values. Record the ratio in the QA table.</li>\n<li><strong>Export \"PPTX\" from Marp or Slidev and call it done:</strong> both rasterise each slide into an image inside the <code>.pptx</code>. Text is not selectable or editable, so the deck the client wanted to edit is a stack of pictures. When editable PowerPoint is the deliverable, route to the <code>pptx</code> skill.</li>\n<li><strong>Notes and directives both live in HTML comments in Marp:</strong> <code>&lt;!-- _class: lead --&gt;</code> is a directive, <code>&lt;!-- Open with the outage story --&gt;</code> is a presenter note. A note that starts with a <code>key: value</code> line silently becomes a directive.</li>\n<li><strong>Fixed pixel type on a web deck:</strong> a deck sized for the presenter's laptop is a different deck on the projector and unreadable on the phone it gets forwarded to. Size in <code>clamp()</code>; Marp and <code>.pptx</code> decks are fixed canvases and take pt sizes instead.</li>\n<li><strong>Presented-deck density on a pitch deck sent by email:</strong> a 3-words-per-slide deck forwarded with no presenter is unreadable. Route to <code>pitch-decks.md</code> at Step 1, not after the deck is built. The inverse also fails: a 60-word slide on a demo-day stage.</li>\n<li><strong>Sparse headlines on pitch decks:</strong> \"Traction\" tells a skimming investor nothing. Write the claim: \"1,000+ customers, $10M ARR\".</li>\n<li><strong>Skipping the spine:</strong> jumping straight to slides produces a list of facts with no arc, then a rewrite once the missing narrative shows. Spine and ending first.</li>\n<li><strong>Speaker notes as a script:</strong> a verbatim script gets read aloud and sounds flat. Notes are prompts: key point, talk-track bullets, transition line.</li>\n<li><strong>Accents outside the section system:</strong> section colours are wayfinding; a random mid-section accent reads as a topic change that never happened. On a full-bleed deck the slide is the accent; the colour changes at the slide boundary, not inside it.</li>\n<li><strong>Paragraphs on slides:</strong> the audience reads instead of listening and the speaker becomes redundant. Cut until the 3-second test passes.</li>\n</ul>\n<h2>Related skills</h2>\n<ul>\n<li>External <code>pptx</code> skill (anthropics/skills) where installed: creating, editing, and QA of the <code>.pptx</code> file.
