Twitter Promo Graphic Generator

Create a beautiful, on-brand PNG promo graphic for Twitter (1200x675, exported at 2x retina as 2400x1350).

Workflow

  1. Research: Read the relevant source code for the feature being promoted. Understand what it does, how users interact with it, and what the UI looks like.
  2. Design: Create an HTML file in promo/ that mocks the real app UI faithfully.
  3. Screenshot: Use Chrome headless to export as a retina PNG.

Brand & Theme

Use the code-theme-black palette from projects/web/src/tw.css:

--base-100: oklch(0% 0 0)           /* #000000 — background */
--base-200: oklch(19% 0 0)          /* #2d2d2d — elevated surfaces, action bar bg */
--base-300: oklch(22% 0 0)          /* #363636 — buttons on base-200 */
--base-content: oklch(87.609% 0 0)  /* #d6d6d6 — primary text */
--primary: var(--color-orange-700)   /* #c2410c — brand orange, Plan buttons */
--primary-content: oklch(1 0 0)     /* #ffffff */
--border: oklch(0.25 0 0 / 0.5)     /* rgba(60,60,60,0.5) */
--muted: oklch(0.55 0 0)            /* #808080 — secondary text */
--success: oklch(51.975% 0.176 142.495) /* #15803d — Do buttons, pass states */
--error: oklch(62.795% 0.257 29.233)    /* #dc2626 — Stop/danger buttons */

Fonts: Inter for UI text, JetBrains Mono for code/mono. Import from Google Fonts.

Component Reference

When mocking the app UI, replicate the actual component structure. Key files:

  • InputBar: projects/web/src/components/InputBar.tsx — the main input component

    • Outer wrapper: absolute bottom-6 left-1/2 -translate-x-1/2 w-full max-w-3xl px-4
    • Container: bg-base-100 border border-border shadow-lg
    • Tray row: flex items-center gap-1 p-1 with 28x28px icon buttons
    • Editor area: min-h-[58px] text-sm leading-[20px], padding px-2.5 py-[9px]
    • Actions row: flex items-center gap-2 px-2 py-2 bg-base-200
    • Button base: btn flex items-center justify-center gap-2 px-4 h-9 text-sm font-medium
    • Variants: success=bg-success, primary=bg-primary, neutral=bg-base-200, danger=bg-error

  • Tray buttons (from trayConfigs.tsx): Changes (GitCompare), Files (FolderOpen), Git Log (GitCommitHorizontal), Search (Search), Terminal (TerminalSquare), Processes (Play) — all size 14, w-7 h-7

  • Sidebar crons: projects/web/src/components/sidebar/CronList.tsx

    • Header: Clock icon + "Crons" + Plus button
    • Each item: flex items-center gap-2 py-1.5 pl-3 pr-2, 8x8 status dot (running=green pulse, active=orange, inactive=gray), text-xs name, hover actions

  • Command buttons (from InputManager.ts): Do (Play, success), Plan (FileText, primary), Ask (MessageCircleQuestion, neutral), Repeat (Repeat, neutral), Close (CheckCircle, neutral with spacer)

Icons are from lucide-react. Use inline SVGs with matching viewBox="0 0 24 24" and stroke-width="2".

Screenshot Command

"/Applications/Google Chrome.app/Contents/MacOS/Google Chrome" \
  --headless --disable-gpu --hide-scrollbars \
  --screenshot="${CLAUDE_SKILL_DIR}/promo/<name>.png" \
  --window-size=1200,675 \
  --force-device-scale-factor=2 \
  "file://${CLAUDE_SKILL_DIR}/promo/<name>.html"

Layout Tips

  • The canvas is exactly 1200x675. Everything must fit — no scroll.
  • When using overflow: hidden on containers (like an app window mock), absolutely positioned children near the edges WILL be clipped. Position overlaying elements (like the InputBar) outside the clipped container.
  • Include a brief marketing header (logo, headline, subline) and a minimal footer.
  • Keep copy punchy and concrete. Show real examples, not abstract descriptions.
  • Use annotation labels in the document flow (not absolutely positioned over content) to call out features.

Output

  • HTML source: ${CLAUDE_SKILL_DIR}/promo/<name>.html
  • PNG output: ${CLAUDE_SKILL_DIR}/promo/<name>.png (2400x1350 retina)

After generating, read the PNG to verify it looks correct before presenting to the user.

Existing Examples
