--- name: docs-page description: | A documentation page — left nav, scrollable article body, right-rail table of contents. Use when the brief mentions "docs", "documentation", "guide", "API reference", or "tutorial". triggers: - "docs" - "documentation" - "guide" - "tutorial" - "api reference" - "文档" od: mode: prototype platform: desktop scenario: engineering preview: type: html entry: index.html design_system: requires: true sections: [color, typography, layout, components] --- # 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: - **Left nav** (240–280px, sticky): grouped link list, current page bolded with a left-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. - **Right 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: - `` through ``, 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). ## Output contract Emit between `` tags: ``` ... ``` One sentence before the artifact, nothing after.
