version: "1.0.0" name: slidex-html-authoring description: Read, create, replace, or repair browser-native OpenSlideX HTML presentations. Use for canonical .html source, packaged offline resources, HTML page mapping, or opaque-origin playback; not for editable native MotionDoc MDX.

OpenSlideX HTML Authoring

Preserve browser-native HTML as canonical source instead of converting its DOM, CSS, or JavaScript into native MotionDoc layers.

Progressive route

Read browser runtime before creating or changing HTML that loads scripts, images, video, fonts, frames, workers, or connections.

For a polished consulting, investment, financial, or long-form HTML deck, also read the IDAEO and Nov reference grammar. It extracts reusable composition and pacing from the two approved reference decks without copying their claims, brands, or private content. Then follow the recommended slidex-deck-design, slidex-motion-direction, and slidex-deck-qa guidance returned by the HTML manifest.

Read and write through the six-tool MCP

1. In Workspace scope, select the intended deck with open_slidex_workspace.
2. Call open_slidex_read with sourceFormat: "html". Read every chunk when

nextCursor is returned and keep the latest revision and htmlSource.

1. For a replacement, call open_slidex_edit with target: "html", the

complete HTML in source, the returned htmlSource, and expectedRevision. Omit htmlSource only when replacing the selected deck with a new HTML deck. When source contains relative local images, also pass their real directory inside the selected deck as htmlAssetRoot. Absolute paths, file: URLs, symlinks, and remote network resources are rejected. The edit copies approved images into assets/, converts PNG to WebP, and rewrites the canonical HTML.

1. Read the saved HTML again and inspect every mapped page in playback. Confirm

the returned pageCount matches the source deck, including plain .slide HTML exports. For long decks, verify every page thumbnail plus first, middle, and last full-screen playback states.

Authored HTML contract

• Prefer one explicit [data-slidex-page] element per page. Legacy .gcard.page

and plain .slide exports remain supported, but explicit markers are the most deterministic authoring contract.

• Use a 16:9 stage, semantic HTML, shared CSS design tokens, stable page numbers,

and a complete static final state. Keep interaction and animation local to the document and honor prefers-reduced-motion.

• Inline SVG and CSS remain part of the canonical HTML and therefore do not

appear as separate files in assets/. Only referenced local sidecars are copied there. Never manufacture duplicate asset files merely to make the folder look populated.

• Full-screen projection must not depend on editor chrome, local absolute paths,

Base64 document storage, or browser extensions.

Never author the generated HtmlEmbedBlock wrapper. Never use open_slidex_edit to convert arbitrary HTML into editable React layers. If native editing or portable PPTX is required, rebuild the visible meaning separately with slidex-react-authoring.
