Gemini Carousel

CRITICAL: Auto-start on load

When this skill triggers, go straight to Step 1. Do not summarise.

Step 1. Gather inputs

Ask:

Paste the content you want in the carousel. A post, section of a newsletter, research notes, or a framework all work.

Wait for the content, then call AskUserQuestion:

[
  {
    "question": "Brand style?",
    "header": "Style",
    "multiSelect": false,
    "options": [
      {"label": "Pull from brand-kit.md", "description": "Use the colours and typography in my project brand file"},
      {"label": "I will type brand colours", "description": "I will paste hex codes and font preferences"},
      {"label": "Suggest for me", "description": "Pick a palette and typography based on the content"}
    ]
  },
  {
    "question": "Number of slides?",
    "header": "Slides",
    "multiSelect": false,
    "options": [
      {"label": "6 slides", "description": "Concise, fast read"},
      {"label": "8 slides", "description": "Standard carousel length"},
      {"label": "10 slides", "description": "Deep-dive carousel"}
    ]
  }
]

Step 2. Build the design brief

Analyse the content and produce a slide-by-slide brief with:

• Slide 1 (Cover): hook, large bold text, visual direction
• Slides 2 to N-1 (Body): one idea per slide, max 15 words per slide, visual suggestion
• Slide N (CTA): repost ask, name, link or offer

For each slide include:

• Slide number
• Headline (max 8 words)
• Body text (max 15 words)
• Visual suggestion (icon, colour block, illustration, diagram)

Tell the user:

Here is the design brief. Tell me what to change, or say "generate" when you are happy.

Wait for approval. Do not proceed until the user explicitly approves.

Step 3. Output per-slide prompts

Once approved, output one Gemini image generation prompt per slide, each in its own code block, numbered clearly.

Every prompt follows this structure:

Act as an expert graphic designer. Create a LinkedIn carousel slide at 1080x1350 pixels (4:5 aspect ratio).

Brand style:
- Primary colour: [HEX]
- Secondary colour: [HEX]
- Accent colour: [HEX]
- Typography: [bold industrial headline font, clean geometric body font]
- Aesthetic: modern, authoritative, high contrast

Slide [N of M]: [slide purpose]

Content:
- Headline: "[headline text]"
- Body: "[body text]"
- Visual element: [specific visual suggestion]

Layout instructions:
- [Headline placement and size]
- [Body placement and size]
- [Visual placement]
- [Background treatment]

Constraints:
- Vertical 4:5 aspect ratio at exactly 1080x1350 pixels
- No watermarks, no logos unless specified above
- Maintain visual consistency with the other slides in the set

Tell the user:

Paste each prompt into a new Gemini chat with Create Image enabled and Nano Banana selected. Generate slides one at a time for maximum control over consistency.

Step 4. Offer one-shot alternative

After the per-slide prompts, offer:

Want a single combined prompt that generates the full carousel in one shot? Faster but less visual consistency. Say "combine" and I will rewrite.

Rules

• Always gate on user approval of the brief before outputting image prompts.
• 1080x1350 pixels per slide. No other aspect ratio.
• Maximum 15 words of body text per slide. Readability loses on the feed.
• Keep the brand style identical across every slide prompt so the set looks like one carousel.
• Cover slide (1) and CTA slide (last) must be visually distinct from body slides.
• Never use em dashes.
• British English unless voice.md specifies otherwise.
• If brand-kit.md exists in the project, read it and use its exact hex codes and typography choices.
