Render a document (PDF / HTML / PPTX / DOCX) and save it to the workspace.

This tool has two input pipelines — pass exactly one of content_html or content_markdown.

Pipeline A — content_html (canonical for decks, proposals, designed pages)

You author full HTML+CSS. A baked-in design-system preamble ships first (<style> with Inter/Manrope as data-URI fonts, CSS-variable palette tokens, 8px spacing scale, and pre-styled layout helpers); your markup and any of your own <style> blocks land after the preamble so you can override anything. Chromium renders the assembled document into a static PDF — JavaScript is disabled and DNS is blackholed, so external font / image / script fetches will fail by configuration.

Required when this pipeline is used:

• title — human-readable, used for PDF metadata and the saved filename.

• content_html — the <body> and any custom <style> blocks. The renderer wraps this in <html>…</html> and injects the preamble + a canonical <meta charset> + <title>. Do NOT emit <script>, <iframe>, <object>, <embed>, <meta>, <link>, <base>, <form>, or event handlers — the sanitizer strips them.

• output_type — "pdf" or "html". ("pptx" and "docx" require content_markdown since they need structured markdown intermediates.)

Optional:

• page_preset — "slide_16_9" (default for any deck), "a4" (default for flowing documents — used if omitted), "letter", or "none" (you declare your own @page rule). For a web-styled page (dark background, full-bleed sections) use "none" and declare @page { margin: 0 }, set the background on html as well as body, and add print-color-adjust: exact — the a4/letter presets keep 24mm paper margins, which paint as a white frame around dark designs.

• design_tokens — flat dict overriding the preamble's CSS variables. Whitelisted keys: brand_primary, accent, surface_dark (hex color), font_display, font_body (font name from ['Inter', 'Manrope', 'monospace', 'sans-serif', 'serif', 'system-ui', 'ui-monospace', 'ui-sans-serif', 'ui-serif']).

• language — BCP-47 tag (default "en"). Drives <html lang>.

Slide structure (page_preset="slide_16_9")

Each slide is <section class="slide …">…</section>. The base .slide class is what sizes it to the viewport and forces the page break — do not drop it. Composable variants (apply alongside .slide):

• .slide-cover — gradient hero, big display title.

• .slide-split — two equal columns, image + narrative.

• .slide-stats — three-up KPI cards (use <div class="stat"> with .stat-value + .stat-label inside).

• .slide-quote — centered pull quote + <cite> attribution.

Layout helpers (work in any preset): .grid-2, .grid-3, .split, .stack, .cluster, .callout, .muted, .kbd.

Speaker notes

<aside class="notes">…text…</aside> inside a <section class="slide">. The sanitizer strips them from the rendered PDF and returns them as slide_notes[] (parallel to slide order). Orphan notes outside any slide are dropped with a warning.

Images

Only these src schemes resolve:

• file:NNN — workspace file_id.

• data:image/...;base64,... — inline.

• https://<host> where <host> ∈ DOCUMENTS_MEDIA_URL_ALLOWLIST. Other URLs are dropped and replaced with an HTML comment placeholder.

Pipeline B — content_markdown (invoice / contract only)

Required:

• title, content_markdown, output_type.

Optional:

• theme — "invoice" or "contract". Triggers the corresponding exemplar styling and (for invoices) the arithmetic validator that fail-closes on missing or mismatched totals.

• language — BCP-47 (default "en").

Delivery contract (CRITICAL)

After this tool returns file_id, deliver the file with messages.send(attachments=[file_id], text="<short caption>"). Embedding the file_id in a markdown link, sandbox: URL, or /api/files/<id>/download text will render as plain text on the recipient's channel — the attachments parameter is the only way the file actually attaches.
