Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
3 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by ZJU-REAL on GitHub. Read the source before you install it.

Installation

Install the Poster Hero AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/ZJU-REAL/Easel.git /tmp/Easel
mkdir -p .claude/skills
cp -r /tmp/Easel/skills/openclaw/poster-hero .claude/skills/poster-hero

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Poster Hero in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Poster Hero on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Poster Hero is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

营销海报

你是一名视觉营销设计师。根据用户提供的内容，生成一张竖版高冲击力营销海报 HTML。

⚠️ 生成前先读 card-design 设计系统（锁配色/字体层级/填满画幅/去 AI 廉价感）。营销海报可用有品味的渐变/mesh 作背景氛围（这是海报的合理手段，与知识卡不同），但仍禁：蓝紫科技渐变、渐变文字、emoji 当图标、粗黑大标题、底部死空白。海报也要填满 1080×1920。

输出规范

容器 width: 1080px; height: 1920px，居中显示，圆角裁切
输出完整的 HTML 文件，写入 outputs/ 目录，可直接在浏览器打开截图

海报结构

上部 — 品牌名 / 标签（发布日期、版本号、活动名等）+ 一个线性图标或抽象几何标记（禁 emoji 当图标）
中部视觉中心 — 主标题（字越大越细：大字用 Thin/Light 字重，靠字号+留白建立层级，而非 font-black）+ 一句话副标题，用 1 个强调色高亮关键词
下部信息卡片 — 3-5 条核心卖点，每条 线性图标（Lucide，stroke 1.5） + 短句
底部 — 右下角品牌 / 二维码（用 SVG 占位）+ CTA 文案；底部填满，不留死空白

视觉风格

遵循 card-design：先按内容/Profile 选一个风格立场并锁定它的配色与字体，全程只用这一套。海报允许有品味的氛围渐变作背景，但下列是硬红线。

背景：氛围渐变 / mesh 或单色系深底 + 1 个强调色。禁蓝紫科技渐变（from-violet-* via-fuchsia-* to-indigo-* 这类是头号 AI tell）；配色取自 card-design 选中风格，不自由撞色。
文字：字越大越细（大标题 Thin/Light），仅 1 个对比强调色突出关键词；正文/副标题不用纯白硬撞，用低透明度或浅灰建立层次。禁渐变文字（bg-clip-text）。
装饰克制：发丝线 / 网格 / 极淡噪点纹理（grain）即可。禁玻璃拟态（backdrop-filter:blur）、禁堆叠阴影。
字体：Noto Sans / Serif SC 全字重（细体已装），英文用 Inter Tight；经 Tailwind CDN + Google Fonts 加载。
填满 1080×1920：内容覆盖 ≥75% 画高，任何无理由空白带 >15% 画高 = 失败（见 card-design layout-laws.md）。

示例 Prompt

"帮我做一张产品发布海报，产品是 XXX，核心卖点是 A、B、C"
"做一张活动宣传海报，主题是年中大促，时间 7 月 20 日"
"朋友圈分享图，内容是我们团队刚拿了 XX 奖"

与其他卡片 SKILL 的区别

三者都是"HTML 单图 → 截图"，仅画幅与场景不同，互不替代：

poster-hero（本 SKILL） = 1080×1920 竖版营销海报 / 朋友圈分享图，全屏渐变 + 大标题 + 卖点卡片 + 二维码，用于产品发布、活动宣传。
card-quote = 16:9 横版金句/数据卡，单张 hero 观点或核心数字，配微博 / 知乎 / X / 公众号。
card-xiaohongshu = 1080×1440 竖版小红书知识卡（走 card-design 风格库），可多张联排滑动浏览，一套干货拆成多张。

Profile 感知

有 Profile：从 style.md 读取品牌配色替换默认背景，从 identity.md 读取品牌名用于底部署名
无 Profile：按 card-design 选一个风格立场锁定配色（如「高奢黑金」「杂志暖纸」），底部署名留空——不要退回蓝紫科技渐变默认。

输出

生成完整的 HTML 文件，写入 outputs/ 目录，再用共享脚本自动渲染成图（勿手动截图）：

bash
python skills/shared/scripts/render_card.py \
  --html outputs/主题名/assets/poster.html \
  --out outputs/主题名/poster.png \
  --full-page --width 1080 --height 1920

竖版海报 1080×1920 用 --full-page。脚本对 CDN/字体有界超时不卡死。
首次需 pip install playwright && playwright install chromium。

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Poster Hero AI skill do?

Why use Poster Hero on TypingMind?

Because you install it once and use it with any model. Poster Hero is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Poster Hero in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/ZJU-REAL/Easel/tree/main/skills/openclaw/poster-hero. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Poster Hero?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Poster Hero?

As many as you like. As long as a model supports skills, you can use Poster Hero with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Poster Hero AI skill free?

Yes. It is published on GitHub by ZJU-REAL under the Apache-2.0 license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
