Interactive Deck Builder
A framework for self-contained HTML presentations: one canvas, many Three.js scenes, click-driven interactions per slide, modal CLI / REPL playback simulator, dark accent-colored design system, live-data tiles fed from any source. Topic-agnostic — bring your own metaphor, your own data, your own scenes.
When to use
The user asks for an interactive HTML / browser presentation, deck with games, or "talk with 3D animations" on any topic.
The user wants Three.js scenes to illustrate a concept (any concept — process flow, market dynamics, scientific phenomenon, system architecture, narrative metaphor).
The user wants slides that show real data baked in from an external source (CSV file, REST API, SQL query, kubectl output, file system, spreadsheet, anything).
The user already has a deck built with this framework and wants a new scene / section / animation added.
Skip this skill when:
The user wants a static deck (Keynote, PowerPoint, Google Slides, plain Markdown). For those, use a presentation-design / animation-principles skill.
The user wants a tech-talk outline without the framework — use a presentation-outline skill.
The user wants pure Three.js fundamentals (scene graph, materials, cameras) without the deck wrapper — use a threejs-webgl skill.
This skill is the framework. Bring complementary skills for content writing, animation theory, design, and Three.js fundamentals.
Required structure
Every deck is a self-contained directory served as static files:
<deck-name>/
├── index.html # <section class="slide" data-section="X" data-color="Y" data-scene="Z"> per slide
├── styles.css # design system: --accent-* colors, .slide, .scene-slide, .fullscreen-scene
├── presentation.js # slide controller, keyboard nav, build steps, scene wiring
├── scenes.js # Three.js scenes — one per data-scene name, registered in `scenes` map
├── demo.js # CLI / REPL / terminal playback simulator (modal, optional)
├── data/ # CSV / JSON / etc. shown on slides AND fed into scenes (optional)
├── code-examples/ # snippets shown on slides AND used by the demo simulator (optional)
├── README.md # how to open + section map
├── OUTLINE.md # section-by-section structural map
└── SPEAKER-GUIDE.md # per-slide talking points (auto-generated from <aside class="notes">)
Run with python3 -m http.server 8765 from the parent directory, then open http://localhost:8765/<deck-name>/.
Workflow
Pick the topic and narrative beats. Map your story to ~6-9 sections. Each section gets one accent color (teal / red / purple / amber / green / blue / cyan / rose / deep-purple). The colors are mood markers, not topic markers — pick what fits the beat (red = problem / alarm, green = fundamentals / safety, blue = scale / depth, cyan = open / cool, rose = warmth / data, etc.).
Capture real data first (optional but high-value). Whatever your topic, find the real numbers that ground it. Sales deck → real revenue / churn / LTV. Lecture → real survey / experiment results. System talk → real cluster output. Product demo → real usage stats. Load references/data-sources.md for the discovery patterns by data source type.
Copy framework files from assets/templates/ into the new deck folder: index.html, styles.css, presentation.js, scenes.js, demo.js. Or run bash scripts/new-deck.sh <deck-name> to scaffold.
Author slides in index.html as <section class="slide" data-section="..." data-color="..." [data-scene="..."]>. Use the established slide types: title, big-statement, framework, code, divider, scene, recap, q-and-a. Load references/slide-types.md for the full template gallery.
Build Three.js scenes for concepts that benefit from interaction. Each scene is a function in scenes.js that returns { scene, camera, update, ... } and is registered in the scenes map. The shipped templates ship ONLY two ambient scenes — particles (title) and aurora (dividers) — so every interactive scene is built per deck, not copied from a shipped library. Load references/scene-recipes.md for structural recipes covering ~12 common patterns (race, particle-flow, click-to-destroy, density / fill-up, slider scaling, force-directed graph, wave generator, topology, color-shift, hub-and-spoke, migration, comparison split-screen). Load references/threejs-scenes.md for the factory contract + accent-color sync + raycasting + scene-local-vs-world-coords gotcha. For Three.js fundamentals (geometries, materials, lighting, performance), defer to a threejs-webgl skill.
Wire each scene to its slide — data-scene="<name>" on the section + matching control elements + a refreshXxxUI() function in presentation.js fed by a callback the scene exposes via setOnChange(). Load references/scene-wiring.md for the wiring contract.
Add demo simulator entries in demo.js (optional) — one per scripted walkthrough. Each entry is an array of { say } (narration) and { run, out, status } (commands + simulated output). Triggered with the D key. Generic enough for any CLI: kubectl, psql, redis-cli, git, npm, AWS CLI, custom REPLs, or scripted shell.
Generate the speaker guide with python3 scripts/extract-speaker-notes.py <deck-dir> after every slide-content change.
Add the fullscreen-scene toggle to every scene slide. Load references/fullscreen-scene-pattern.md if a slide's right panel overflows the viewport in fullscreen mode — the fix is position: fixed + grid minmax(0, ...) + overflow: hidden.
Validate by opening in a browser. Don't trust the build alone. Walk every slide with arrows, toggle fullscreen on every scene, open the demo modal on D, confirm section colors render distinctly. Load references/qa-checklist.md for the full pre-talk list.

Top gotchas (always inline — do not skip)
Three.js scene-local vs world coords. When a scene is offset (e.g. scene.position.y = 3.5 to push it into the upper viewport), child positions are scene-local. If you target an object via obj.getWorldPosition(wp), you must scene.worldToLocal(wp) before assigning to a particle whose movement is computed in scene-local space. Otherwise particles aim N units off and never visually arrive.
Fullscreen-scene CSS must use position: fixed + grid minmax(0, ...).position: absolute + flex inside the slide can overflow the viewport on the right. Use min-width: 0; overflow: hidden on grid children to prevent text from blowing out the bar.
canvas.style.pointerEvents defaults to none so clicks pass through to slides. Toggle to 'auto' only on slides that need raycasting. Forgetting this means the user can't click anything in the scene.
Aurora gradient shader needs a section-color setter. When you switch slides, call scene.setColor(ACCENT[color]) so the divider's radial gradient matches. Forgetting this is why every section divider looks the same.
Build-step navigation runs first. Pressing → first runs build steps inside the slide (progressive bullet reveals, code-line highlights), then advances to the next slide once steps are exhausted. Track this in slide controller state, not on the scene.
Real-data discovery is read-only. Whether your source is kubectl, a SQL query, a REST API, or a file scan — pick read-only operations during deck-building. Never run write / destructive ops while authoring slides.
Pick a concrete metaphor before coding the scene. "A 3D representation of X" is not a scene — it's a wish. Land on a specific physical metaphor (boxes filling a server, particles flowing through gates, balls bouncing on a curve, a force-directed graph relaxing) before writing Three.js.
Topic-agnostic does not mean topic-blind. The framework is generic; each deck is specific. Start with the narrative, then the metaphors, then the scenes — not the other way around.
What you DO
Treat the framework templates as the source of truth — copy and extend, do not refactor speculatively.
Capture real data with the appropriate discovery script before writing the "real numbers" section.
Build each scene as a small, focused module (~150-300 lines) illustrating exactly one concept.
Use the section accent color in code-block borders, progress bar, kicker text, and aurora gradient — visual continuity matters.
Write speaker notes inline in <aside class="notes"> so they show up in both the runtime panel (S key) and the generated SPEAKER-GUIDE.md.
Add a ▶ Play full-screen toggle button to every scene slide so the 3D scene can take over without slide content covering it.
Pair this skill with complementary skills: a presentations / presentation-design skill for animation principles + slide design, a presentation-content skill for content writing, a threejs-webgl skill for 3D fundamentals, an outline / pitch-deck skill for narrative structure.
What you do NOT do
Generate Three.js scenes from prose ("a 3D representation of "). Pick a concrete metaphor first, then code.
Put more than 5 bullets on a slide — split it.
Use stock images, clip art, or emoji decoration. The deck's visuals are Three.js + accent colors + typography.
Animate everything — section dividers and big-statement slides should be still.
Skip the speaker guide. The deck is half the artifact; the talk is the other half.
Commit credentials, internal hostnames, real customer data, or anything that leaks production / private info beyond what is already public.
Re-implement Three.js fundamentals in this skill's references — defer to a threejs-webgl skill. This skill teaches the integration pattern (one canvas, scene registry, slide-driven scene switch, accent-color sync) — not how to use materials and lights.
Make assumptions about the topic. The framework is topic-agnostic; ask the user for their narrative before scaffolding scenes.
