A content-to-image tool that turns written material into PNG visuals using several fixed layouts, including long reading cards, infographics, multi-card sets, comics, and whiteboards.

Use it to make reading cards, adaptive infographics, multi-page card sets, editorial visual notes, black-and-white manga-style pages, marker-style diagrams, or large-text quote cards.

It helps present text as shareable visual content without manually designing each image or splitting the material into cards.

plain-card — Skill for Claude Code by happydog-intj

Install

Getting it into your agent

There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

Made for: Claude Code.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00224	$0.01282
Opus 5	$0.00112	$0.00641
Sonnet 5	$0.00045	$0.00256
Haiku 4.5	$0.00022	$0.00128

Security

Grade A, and why

plain-card 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 (assets/capture.js), 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.

ljg-card: 铸

将内容铸成可见的形态。内容进去，PNG 出来。模具决定形状。

参数

参数	模具	尺寸	说明
`-l`（默认）	长图	1080 x auto	单张阅读卡，内容自动撑高
`-i`	信息图	1080 x auto	内容驱动的自适应视觉布局
`-m`	多卡	1080 x 1440	自动切分为多张阅读卡片
`-v`	视觉笔记	1080 x auto	编辑式杂志专题：问题→失败→转折→顿悟→命名（6 layout 模具 / 4 字族对比 / 探案档案细节）
`-c`	漫画	1080 x auto	日式黑白漫画风格，动态选择漫画家视觉语言
`-w`	白板	1080 x auto	白板马克笔风格，结构化框图+箭头+彩色标记
`-b`	大字	1080 x 1440	碑刻大字 + 和紙 + 外阴影，小红书附件风格（单句/短段）

约束

本 skill 输出为视觉文件（PNG），不适用 L0 中的 Org-mode、Denote 和 ASCII-only 规范。

共享基础

获取内容

URL --> WebFetch 获取
粘贴文本 --> 直接使用
文件路径 --> Read 获取

文件命名

从内容提取标题或核心思想作为 {name}（中文直接用，去标点，≤ 20 字符）。

Logo

模板中 {{LOGO}} 变量统一从以下路径读取 base64 data URI：

with open("/Users/a10093140/Documents/Github/feishu-style-card-image/assets/logo_base64.txt") as f:
    logo_uri = f.read().strip()

Footer 署名为 AI炼丹师（已替换模板中原有的「李继刚」）。

截图工具

node assets/capture.js <html> <png> <width> <height> [fullpage]

从 skill 根目录运行。依赖 skill 根目录下的 node_modules/ 中的 playwright。如报错：

npm install playwright && npx playwright install chromium

Footer

左侧：logo + AI炼丹师（已硬编码在模板中）
右侧：内容来源（可选）——有明确来源时显示（如作者名、arxiv ID、网站名等），无来源时留空。使用 {{SOURCE_LINE}} 变量：有来源时填 <span class="info-source">来源文字</span>，否则空字符串。适用于 -l、-i、-v、-c、-w 模具（-m 多卡无 footer，不适用）。

交付

报告文件路径

品味准则

所有模具共享。执行任何模具前，先 Read references/taste.md，作为视觉质量底线贯穿全流程。

核心：反 AI 生成痕迹——禁 Inter 字体、禁纯黑、禁三等分卡片、禁居中 Hero、禁 AI 文案腔、禁假数据。

执行

根据参数选择模具，Read references/taste.md + 对应的 mode 文件，按步骤执行：

-l（默认）：长图

Read references/mode-long.md，按其步骤执行。

模板：assets/long_template.html

-i：信息图

Read references/mode-infograph.md，按其步骤执行。

模板：assets/infograph_template.html

-m：多卡

Read references/mode-poster.md，按其步骤执行。

模板：assets/poster_template.html

-v：视觉笔记

Read references/mode-sketchnote.md，按其步骤执行。

模板：assets/sketchnote_template.html

-c：漫画

Read references/mode-comic.md，按其步骤执行。

Files

What ships with it

20 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.
