visual-idea-generator

A guide that turns a post idea into text prompts and layout plans for thumbnails, carousels, and short-video covers.

In plain words
What is it for?
Use it to plan social-media graphics, choose the main subject and on-image wording, and create image prompts with a style and shape for each asset.
Why use it?
It removes the guesswork from deciding what each visual should show, say, and look like. The prompts can be pasted into image-making tools.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

visual-idea-generator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Visual Idea Generator

A visual has ~0.4 seconds to win the scroll, so it must communicate ONE idea pre-read: a single subject, one emotion, one promise. Attention is won by contrast and curiosity, not detail — the eye locks onto a human face showing emotion, then reads at most 3 words, then decides. Design from the thumbnail backwards: pick the emotional beat first, compose for a 120px-wide phone preview, and only then write the generation prompt. This skill outputs briefs and prompts you paste into an image tool; it never claims to render pixels itself.

1. Thumbnail psychology (the 5 laws)

  1. One subject, one focal point. A face, an object, or a before/after — never all three. If you can't name the subject in one word, cut.
  2. Emotion on a face beats everything. Wide eyes, open mouth, genuine shock/joy. Faces looking AT the viewer or AT the object of interest. This is the single biggest CTR lever.
  3. Contrast is king. Subject must pop off the background: rim light, blurred/darkened backdrop, or complementary color behind the subject (orange subject on teal, yellow on navy). Avoid busy backgrounds.
  4. ≤3 words of on-image text, 1 short line, huge and bold (readable at 120px). Text and face must not overlap. Use a punchy word ("WRONG", "$0 → $10K", "DON'T").
  5. Curiosity gap, not spoiler. Show the stakes, hide the payoff. "I tried it for 30 days" + a shocked face beats "It grew 4x." Open a loop the title/caption closes.
  1. Cover slide = the hook. Big claim or number + a visual promise of value. Add "swipe" affordance (arrow, "1/7", cut-off next slide). This slide alone decides swipe-through — spend 50% of effort here.
  2. Value slides (3–8). One idea per slide, consistent template (same margins, font, accent color). Number them. Front-load the best 2 tips — most drop-off happens by slide 3. Use tension → resolution per slide.
  3. CTA slide. Recap in one line, then ONE ask: follow, save, comment a keyword, or "share this." Never stack CTAs. Restate the handle.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
