Docs Page Skill

Produce a single, three-column documentation page in one HTML file.

Workflow

1. Read the active DESIGN.md (injected above). Use the body type token for prose; the mono token for code; respect line-height and max-width rules.
2. Pick a topic from the brief — the page should look like real docs, not a generic wireframe. Concrete API names, command examples, plausible parameters.
3. Lay out three regions, expressed on the inline axis so the layout flips correctly under dir="rtl":
   • Inline-start nav (240–280px, sticky): grouped link list, current page bolded with an inline-start-edge accent stripe. 3–5 groups of 4–8 links.
   • Article body (max-width ~720px, centered in the middle column): H1, lede paragraph, H2 sections, code blocks, callout boxes (note / warning), inline links, lists.
   • Inline-end TOC (200–240px, sticky): "On this page" with the H2/H3 anchors, current section highlighted as the user scrolls.
4. Write a single HTML document:
   • <!doctype html> through </html>, all CSS inline.
   • CSS Grid for the three columns; sticky positioning for the rails.
   • Code blocks: monospace token, soft surface fill, copy-button affordance (visual only — no JS needed).
   • Anchor IDs on every H2/H3 so the TOC links work.
   • data-od-id on the nav, article, and TOC.
5. Prose: write at least 350 words of believable docs. Include at least one shell command, one code snippet (5–15 lines), one callout, one table.
6. Self-check:
   • Body text wraps at the DS line-length sweet spot (60–75 chars).
   • Code uses the DS mono token, not generic monospace.
   • Accent is restrained — used for active nav item, links, one callout border. Not on body text.
   • Page is readable at 1280w and collapses gracefully below 900w (TOC drops out, nav becomes a top drawer).
   • Use logical CSS (margin-inline-start, border-inline-start, inset-inline-end, text-align: start) on the rails and accent stripe so the layout flips correctly under dir="rtl".

Output contract

Emit between <artifact> tags:

<artifact identifier="docs-slug" type="text/html" title="Docs — Page Title">
<!doctype html>
<html>...</html>
</artifact>

One sentence before the artifact, nothing after.
