Content caster (鑄). Converts content into PNG visuals. There are six available templates: -l (default) long reading card, -i infographic, -m multi-card reading cards (1080x1440), -v visual sketchnote, -c comic (black and white manga style), -w whiteboard (marker-style board layout). Output files are saved to ~/Downloads/. This skill is triggered when the user mentions terms such as '鑄', 'cast', '做成圖', '做成卡片', '做成資訊圖', '做成海報', '視覺筆記', 'sketchnote', '漫畫', 'comic', 'manga', '白板', 'whiteboard'. It replaces the former ljg-cards and ljg-infograph skills.

Shared Foundations

Content Retrieval

URL --> fetched via WebFetch
Pasted text --> used directly
File path --> fetched via Read tool

File Naming

Extract the title or core idea from the content as

{name}

(Chinese text can be used directly, remove punctuation, ≤ 20 characters).

Screenshot Tool

bash

node ~/.claude/skills/ljg-card/assets/capture.js <html> <png> <width> <height> [fullpage]

Dependencies:

playwright

in

~/.claude/skills/ljg-card/node_modules/

. If you encounter an error, run:

bash

cd ~/.claude/skills/ljg-card && npm install playwright && npx playwright install chromium

Footer

Left side: logo + Li Jigang (hardcoded in the template)
Right side: Content source (optional) -- displayed when there is a clear source (such as author name, arxiv ID, website name, etc.), leave blank if no source exists. Use the
```
{{SOURCE_LINE}}
```
variable: fill with
```
<span class="info-source">source text</span>
```
when source is available, otherwise use empty string. Applies to
```
-l
```
,
```
-i
```
,
```
-v
```
,
```
-c
```
,
```
-w
```
templates (the
```
-m
```
multi-card template has no footer, so this rule does not apply).

Taste Guidelines

Shared by all templates. Before running any template, read

references/taste.md

first, and take it as the visual quality baseline throughout the entire process.

Core: Avoid AI generation traces -- prohibit Inter font, pure black color, three-equal-part cards, centered Hero sections, AI-style copywriting, fake data.
