使用说明 (SKILL.md)
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 \x3Copenclaw-install-dir>/skills/nano-banana-pro/scripts/generate_image.py \
--prompt "\x3Cslide 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.

安全使用建议
This skill appears coherent and small. Things to consider before installing: (1) It relies on another skill (nano-banana-pro) — verify that skill's source and permissions because image generation is delegated to it. (2) The included convert_jpg.py will pip-install Pillow at runtime if missing, which downloads packages from PyPI — if you require an offline or locked environment, pre-install Pillow or inspect and sandbox the execution. (3) The SKILL.md references a TOOLS.md browser upload flow not included here — confirm how uploads are handled in your environment. If you plan to run this in a shared or sensitive environment, run the converter in a sandbox or review/approve the nano-banana-pro skill first.
功能分析
Type: OpenClaw Skill
Name: cardnews
Version: 1.0.0
The `SKILL.md` instructs the OpenClaw agent to construct and execute shell commands (`uv run`, `python3`) where parameters like image prompts and filenames are derived from user input (the 'topic'). This creates a significant shell injection vulnerability if the agent does not properly sanitize or escape user-provided input before executing these commands, potentially leading to arbitrary command execution. While the `scripts/convert_jpg.py` file itself is benign, its execution is part of this vulnerable command construction pattern.
能力评估
Purpose & Capability
Name/description match the content: planning slides, generating images via another image-gen skill (nano-banana-pro), converting PNG→JPG, caption writing, and upload prep. Required binaries/env/config are empty and consistent with an instruction-only skill that delegates image creation to another skill.
Instruction Scope
SKILL.md stays on-task (plan slides, call nano-banana-pro to generate PNGs, convert to JPG, write caption, use browser upload). It references running a script from the nano-banana-pro skill and a browser-based TOOLS.md workflow — these are reasonable but require the nano-banana-pro skill and the TOOLS.md upload doc to be present and trusted. The instructions don't ask for unrelated files, credentials, or system-wide config.
Install Mechanism
No install spec (instruction-only) which is low-risk. The included convert_jpg.py will attempt to pip-install Pillow at runtime if it's missing (via subprocess.check_call). That behavior performs a network package install when first run — not inherently malicious but worth noting because it writes packages to the environment at runtime.
Credentials
Skill declares no environment variables, no credentials, and no config paths. SKILL.md does not reference environment variables or secrets. The lack of external credential requests is proportionate to the stated purpose, though the skill delegates image generation to another skill which may have its own credential needs.
Persistence & Privilege
always is false and the skill does not request permanent presence or modify other skills. It contains a small utility script but does not change system or agent-wide settings.
