Article To Html

article-to-html

Turn a document (from conversation context or a given markdown file) into a self-contained HTML file, reusing the "paper proposal" design system defined in references/template.html: serif body + monospace meta + numbered sections + inline SVG figures + callouts + tables + optional JS interactivity.

Flow after trigger

1. Get the source. If the user gave a file path, Read it. If the draft is in conversation context, use that directly.
2. Extract document skeleton. Title, subtitle, TL;DR, section list, whether figures are needed, whether tables are needed, whether interactivity is needed.
3. Read the template. Read references/template.html and use its full CSS + structure as the scaffold.
4. Read the component reference. Read references/components.md and pick out the snippets you need this round.
5. If figures are needed: consult references/svg-figures.md and draw with inline SVG (no external image references — keep the file portable).
6. If interactivity is needed: consult references/interactive.md and append a <script> block before </body>.
7. Output. Write to {same dir as source or current working dir}/{slug}.html. Filename = English slug of the title, or whatever the user specified.
8. Report. One sentence with the file path + a one-line command to open it in a browser.

Design invariants (do NOT break)

• Single file. All CSS / SVG / JS inline. No external fonts, no CDNs, no remote images.
• Don't change the paper palette. --paper: #f7f7f5 + --ink: #1a1a1a is this skill's visual signature. If the user explicitly asks for a different mood (dark mode, different accent), you can change --accent / --warn, but keep paper/ink.
• Serif body + monospace meta. body uses ui-serif; every "metadata slot" (.doc-eyebrow / .doc-meta / th / code / figcaption / .num) uses ui-monospace. This mix is the signature.
• Section numbering prefix. <h2><span class="num">01</span>Section title</h2> — small monospace, faint gray, 14px gap to the title. Add it even if the source has no numbers.
• Figures need figcaption. <figcaption><span class="fig-num">FIG 1</span>caption text</figcaption>, the FIG N in accent color.
• TL;DR always on top. If the source has no TL;DR, condense the first one or two paragraphs into a ~60-word summary and put it there.
• No "generated by AI" footer watermark unless the user explicitly asks.

Component cheat sheet

Interactive elements (optional)

The template is static by default. Add interactivity proactively when the document clearly benefits:

• Section collapse / expand (long documents)
• "Copy" button on code blocks
• Table filter / sort (great for vendor comparison tables)
• Dark mode toggle (persisted to localStorage)
• TOC + scrollspy
• Forms (e.g. for an RFC / decision doc, a "vote / leave comment" form persisted to localStorage)

Specific snippets in references/interactive.md. Default to none unless (a) the doc is long — ≥3 sections + ≥2 figures, or (b) the source is interaction-shaped (tutorial, decision doc, vendor selection).

Naming and output location

• Filename: English slug of the title, lowercase, hyphenated, ≤40 chars. For Chinese titles, use pinyin or a translated keyword hint, e.g. 《新基建提案》→ infra-proposal.html.
• Output location:
  • If the user gave a source markdown path, output in the same directory.
  • Otherwise output in the current working directory.
  • If the user specifies a path, honor it.
• If a file with the same name exists, append -v2 / -v3. Never silently overwrite the user's existing output.

Common mistakes

• Recoloring the CSS. Don't touch paper/ink/accent unless the user said "different palette please". Visual consistency is the entire point.
• Switching body to sans-serif. The whole "proposal paper" feel hinges on the serif body. Changing fonts breaks the look.
• Using emoji as icons. The character vocabulary of this skill is uppercase monospace labels + small color blocks (.mascot / .layer-icon). No emoji unless the user explicitly asks.
• External <img src="https://...">. Kills portability. Either inline SVG, base64, or omit.
• Missing figcaption numbers. The FIG 1 / FIG 2 / FIG 3 running labels are key to the "academic paper" feel.
• Callout on every paragraph. Callouts highlight one or two passages, not decorate. Keep total callouts ≤ 5 per document.
• Cramming 5 items into the three-column cards. Switch to repeat(N, 1fr) (or use the .cols-N modifier), don't force wrap.
• Leaking domain-specific names from the example. The template is blank; if the source doesn't mention Crewlet / Anthropic / etc., the HTML shouldn't either.

File manifest

• references/template.html — blank scaffold (full CSS + placeholder structure). Start here.
• references/components.md — cut-and-paste HTML snippets for every component.
• references/svg-figures.md — five typical SVG figure skeletons (architecture, timing, bar comparison, stacked layers, lifecycle).
• references/interactive.md — JS snippets (collapse, copy, table filter/sort, TOC, dark mode, form → localStorage, reading progress, figure zoom).
• assets/example.html — a completed reference render (the original Chinese article.html kept as a visual benchmark).
