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

cardnews 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 11d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/convert_jpg.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.

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

Card News (카드뉴스) Pipeline 🐧

Topic → 5-slide plan → image generation → JPG conversion → caption → Instagram upload.

Workflow

1. Content Planning

Given a topic, plan 5 slides:

Slide Role Content
1 Hook Bold question or surprising statement to stop scrolling
2 Problem/Context Why this matters
3 Core insight Key information or explanation
4 Detail/Example Supporting evidence or practical example
5 CTA/Summary Takeaway + follow/save prompt + 🐧 branding

2. Image Generation (nano-banana-pro)

Generate each slide as 1024×1024 PNG using the nano-banana-pro skill:

# Path may vary based on installation
uv run <openclaw-install-dir>/skills/nano-banana-pro/scripts/generate_image.py \
  --prompt "<slide prompt>" --filename "cardnews-TOPIC-N.png" --resolution 1K

Prompt structure per slide:

  • Include exact Korean text to render (in quotes)
  • Specify: dark background, neon cyan (#00FFFF) accent text, white primary text
  • Include 🐧 penguin emoji on slide 5
  • No English unless the topic requires it

See references/design-guide.md for visual style rules.

3. PNG → JPG Conversion

Instagram rejects PNG frequently. Always convert:

python3 {baseDir}/scripts/convert_jpg.py cardnews-topic-1.png cardnews-topic-2.png ...

Outputs *-ig.jpg files (1024×1024, quality 92).

4. Caption Writing

Write an Instagram caption in Korean:

  • 1-2 line hook matching slide 1
  • 3-5 hashtags (mix of broad + niche)
  • End with CTA: "저장하고 나중에 다시 보세요 📌"

5. Instagram Upload

Use the browser-based upload flow documented in TOOLS.md ("인스타그램 게시물 업로드" section). Upload all 5 JPG files as a carousel post.

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
