skillboardOpenDesign internals: how the agent stream, sandbox, and artifacts work — an engineering deep-dive talk. Built as a decision-grade AI literacy deck for engineers, dev community.
A focused entry point into the html-ppt master skill that lands the user directly on the tech-sharing full-deck template.
The Examples gallery wires "Use this prompt" to the example_prompt above. When you accept that prompt, this card is the right pick if the user wants exactly the visual identity of tech-sharing (see the upstream full-decks catalog for screenshots and rationale).
design-templates/html-ppt/SKILL.md — content/audience checklist,
token rules, layout reuse, presenter mode, the keyboard runtime, and the
"never put presenter-only text on the slide" rule.design-templates/html-ppt/templates/full-decks/tech-sharing/ — copy index.html and
style.css into the project, keep the .tpl-tech-sharing body class.index.html links the shared CSS/JS via ../../../assets/... because it
sits three folders deep inside design-templates/html-ppt/templates/full-decks/.
Once you copy index.html into the project, those parent-relative URLs
no longer resolve and base.css, animations.css, and runtime.js
will 404 — meaning the deck never activates and slide navigation is
dead. Pick one of these two recipes per project:
design-templates/html-ppt/assets/fonts.css, design-templates/html-ppt/assets/base.css,
design-templates/html-ppt/assets/animations/animations.css, and
design-templates/html-ppt/assets/runtime.js into a project-local
assets/ (with assets/animations/animations.css), then rewrite the
four <link>/<script> tags in index.html from
../../../assets/... to the matching project-local paths
(assets/fonts.css, assets/base.css,
assets/animations/animations.css, assets/runtime.js).<link rel="stylesheet" href="../../../assets/..."> with a
<style>...</style> containing the file's contents, and the
<script src="../../../assets/runtime.js"> with a
<script>...</script> containing runtime.js. Yields a single
self-contained index.html.
Either way, do not ship the upstream ../../../assets/... URLs
verbatim into a project artifact — they only work in-tree.design-templates/html-ppt/assets/themes/*.css
via <link id="theme-link"> and let T cycle..tpl-tech-sharing scoped CSS only
recognises the structural classes shipped in the template — keep them.<aside class="notes"> or <div class="notes"> — never as visible text on the slide.Visual system, layouts, themes and the runtime keyboard model come from
the upstream MIT-licensed lewislulu/html-ppt-skill. The
LICENSE file ships at design-templates/html-ppt/LICENSE; please keep it in place when
