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 B, and why

carousel-builder scanned grade B with 1 finding 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 3d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/run.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Asks the agent to reveal its instructionsmediumSystem prompt leakage

Directions to print, repeat or translate the system prompt extract configuration the operator did not intend to expose.

- Per shot: the slide PNG path as `image_url` + a one-line summary of the slide's overlay text (so the LLM can pick a motion that fits the slide's rhetoric — it must NOT re-describe the text in the output prompt).

How it starts

The opening of the file, as written. The whole thing — 253 lines — stays where its author put it; the contents beside it link to each section on GitHub.

This skill orchestrates four lower-level skills:

  1. essay-write or viral-text → drafts the content
  2. image-prompt style anchor + per-slide prompts
  3. common/runners execute layer → batch generation via the chosen provider
  4. common/style-library/carousel/ → style anchor (24 bundled styles + user overrides)

Use when the user wants a finished carousel, not just prompts. Without --execute, returns the 8 prompts + captions for manual paste; with --execute, generates and saves the actual PNG slides.

This skill does NOT:

  • Compose the slides into a single tall image — Instagram / LinkedIn handle multi-image posts natively.
  • Add text overlays via a design tool — text either gets generated INSIDE the image (gpt-image-2 / Ideogram / Imagen) via --text-mode embedded, or is left to the user's editor (--text-mode overlay).
  • Generate animated carousels (those are reels — use reel-builder).
  • Post to platforms — that is post-publisher, which takes this skill's output directory as its input.

ROLE

Topic / research → split content into N slides → pick style + model → assemble 8 per-slide prompts (style anchor + slide content + composition hint) → batch execute via image provider (one provider for all slides for consistency) → write slides + captions + manifest → print final paths.

PIPELINE (v2.14.0+ — promptCarousel chain, mirrors figma/app/lib/carousel/promptCarousel/)

  1. Resolve input — topic OR research brief OR finished post text:
    • --research <path>: read the brief, extract TL;DR / key facts / suggested angles as the topic.
    • --content-file <path>: user-supplied finished post text. PRESERVE the author's voice — direct quotes + cuts only, no paraphrasing. If the text contains ==word== accent markers, those words become accent-color callouts on the relevant slides.
    • --topic "<text>": short topic string. Optionally invoke viral-text (IG/TikTok) or essay-write (LinkedIn) first to produce ~150-220 word post text with ==accents== if the topic is rich enough to benefit. For pure promo decks (course invitation / product launch), topic-only is sufficient.

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.
