+# Social Media Dashboard Skill
+
+Produce a single-screen, creator-facing social media analytics dashboard.
+
+## Workflow
+
+1. **Read the active DESIGN.md** (injected above). Colors, typography,
+   spacing, radii, and component styling all come from it. Do not invent
+   new tokens; do not hard-code brand colors of the platforms — let the
+   DESIGN.md carry the visual identity, and reference platforms only by
+   name and monogram.
+2. **Identify** which platforms the brief calls out. Default to
+   X / LinkedIn / YouTube / Instagram if unspecified. Keep the platform
+   switcher to a single row, max 5 entries.
+3. **Generate plausible data**, never `Metric A / Metric B` placeholders.
+   Pick a creator persona (default: "AI / design indie creator") and
+   derive consistent numbers across the page — e.g. follower counts on
+   the switcher must match the KPI row when X is selected.
+4. **Lay out** the page top-to-bottom:
+   - **Header bar**: brand mark + section label ("ANALYTICS"), a
+     dark/light toggle, time-range tabs (7D · 30D · 90D · YTD), and a
+     creator avatar block on the right.
+   - **Hero strip**: a one-sentence summary in display type
+     ("You shipped 14 posts on X this week."), one supporting line of
+     metadata, and two CTAs ("Export report", "New post →").
+   - **Ask bar**: a single-line input styled as a search field, with
+     ghost-text suggestions ("top performing last week",
+     "comments from verified accounts").
+   - **Platform switcher**: 4 cards in one row, each with platform
+     monogram, name, follower count, and a `+X.XK this week` delta. The
+     active platform uses an elevated surface from DESIGN.md.
+   - **KPI row**: 4 cards — Followers · Engagement Rate · Likes (7D) ·
+     Reposts (7D). Each card has a label (uppercase, label-md), a big
+     value (display or headline-lg), a delta vs prior period, and a
+     small footnote ("vs. 4.4% last week", "Aug 9–17 · 14 posts").
+   - **Main grid (2/3 + 1/3)**:
+     - Left: **Follower Growth · 30D** — a full-width inline SVG line
+       chart with a soft area fill underneath, axis ticks at start /
+       midpoint / end, and two labelled annotation dots
+       ("Newsletter drop +842", "Viral thread +1.2K").
+     - Right: **Top Post · This Week** — a card showing the rendered
+       post (avatar, handle, post body, optional 16:9 media block), with
+       a header tag "click-through rate 5.6%" in the DS accent.
+   - **Lower grid (1/2 + 1/2)**:
+     - **Trending topics on this platform**: 5–7 chip-style rows with
+       topic name + post count + 24h delta sparkline (10 polyline
+       points, no labels).
+     - **Top comments**: 3 cards, each with avatar, handle (verified
+       check if relevant), comment body (2 lines max, ellipsised), and
+       a small `❤ 312 · 💬 18` row in muted text.
+5. **Write** one self-contained HTML document:
+   - `<!doctype html>` through `</html>`, CSS in one inline `<style>` block.
+   - CSS Grid for page-level layout; Flexbox inside cards.
+   - Semantic HTML: `<header>`, `<main>`, `<section>`, `<article>`.
+   - Tag each logical region with `data-od-id="slug"` for comment mode:
+     `header`, `hero`, `ask`, `platform-switcher`, `kpis`,
+     `follower-growth`, `top-post`, `trending`, `top-comments`.
+6. **Charts**: inline SVG only, no JS libraries.
+   - Line chart: `<path>` for the curve, a second `<path>` with low-alpha
+     fill for the area, two `<circle>` annotation dots with text labels.
+   - Sparklines: `<polyline>` with 10 points, no axes, ~16px tall.
+   - Use the DS accent for highlights and the DS `on-surface-variant` for
+     muted text. Accent appears at most three times on the page.
+7. **Self-check**:
+   - Every color resolves to a DESIGN.md token (or a documented
+     `rgba(token, alpha)` for glass surfaces).
+   - Numbers are internally consistent (switcher follower count matches
+     the active platform's KPI).
+   - Header bar and hero strip are sticky; main content scrolls.
+   - Density follows the DS mood: glass / cosmic DSes get more breathing
+     room and ambient glow on the active platform; clean / corporate DSes
+     tighten gaps and drop the glow.
+
+## Output contract
+
+Emit between `<artifact>` tags:
+
+```
+<artifact identifier="social-media-dashboard" type="text/html" title="Social Media Dashboard">
+<!doctype html>
+<html>...</html>
+</artifact>
+```
+
+One sentence before the artifact, nothing after.
