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

carousel-builder 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 3d 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.

What it actually says

Produce multi-slide carousel images from HTML/CSS templates.

Process

  1. Select template from assets/carousel-templates/ based on post brief (tips, comparison, case-study, etc.)
  2. Inject content: slide text, data points, brand colors, fonts, images
  3. Apply brand-config.json styling (colors, fonts, logo)
  4. Render each slide via Playwright (headless Chromium → PNG screenshot)
  5. Compile slides into carousel PDF
  6. Resize slides for target platform dimensions

Templates Available

  • generic-8slide.html — General purpose
  • comparison-10slide.html — Feature comparisons
  • case-study-10slide.html — Client success stories
  • tips-5slide.html — Quick tips format
  • playbook-8slide.html — Step-by-step playbooks
  • recap-6slide.html — Event/month recaps
  • data-infographic-6slide.html — Data-driven infographics
  • quote-card-single.html — Single quote cards

Rules

  • All slides must use brand fonts and colors from brand-config.json
  • First slide = hook/title, last slide = CTA with brand logo
  • Max text per slide: 40 words (LinkedIn), 25 words (Instagram)
  • Show user first and last slide preview before rendering full set

Scripts Used

  • render_carousel.py — Playwright HTML→PNG rendering

Timeout & Fallback

  • Per-slide render: 15-second timeout. If Playwright hangs, retry without custom fonts.
  • Full carousel: 2-minute timeout for 10 slides.

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.
