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.
1 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by xianyu110 on GitHub. Read the source before you install it.

Installation

Install the Platform Spec Export 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.
https://github.com/xianyu110/ecommerce-video-skills/tree/main/skills/platform-spec-export
Enable the skill in any chat where you want it available.

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/xianyu110/ecommerce-video-skills.git /tmp/ecommerce-video-skills
mkdir -p .claude/skills
cp -r /tmp/ecommerce-video-skills/skills/platform-spec-export .claude/skills/platform-spec-export

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

Use it in TypingMind

Enable Platform Spec Export 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 Platform Spec Export 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 Platform Spec Export 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.

`--platform`	输出	用途 / 需确认
`douyin`	1080×1920 · 30fps	抖音信息流/商品视频；上限以创作者中心为准
`tiktok`	1080×1920 · 30fps	TikTok 信息流
`tiktok-shop`	1080×1920 · 30fps	TikTok Shop 商品/联盟视频；以 Seller Center 为准
`channels`	1080×1920 · 30fps	视频号；信息流预览可能裁切，主体和标题放中部

步骤 Steps

bash
python scripts/export_platform.py out/master.mp4 --platform douyin tiktok-shop channels xiaohongshu taobao-main amazon
python scripts/export_platform.py out/master.mp4 --platform all --outdir out/export
python scripts/export_platform.py out/master.mp4 --platform xiaohongshu --mode crop --focus-y 0.4   # 裁切而非模糊填充
python scripts/export_platform.py out/master.mp4 --safe-preview out/safe.png                    # 安全区叠加图

母版先按 9:16 做好（字幕已在安全区内）。
选择转换方式：blur（默认，保留完整画面，上下/左右模糊填充）或 crop（填满画面，会裁掉边缘 → 检查字幕和商品）。
读 export_report.json：分辨率、时长、大小、注意事项。
9:16 → 16:9 时字幕会变小，重要平台建议用 assemble.py --size 1920x1080 重新渲染而不是转码。

安全区 Safe zones

--safe-preview 在一帧上叠加三块经验区域（顶部状态栏 ~9%、右侧按钮栏 ~15% 宽、底部文案/商品卡 ~22%）。这些是经验值，最终以真机预览为准。

常见问题与修复 Failure fixes

问题	修复
上传后糊	平台二压；保证源 1080p、码率不要过低，避免大面积细噪点/渐变
上传失败：文件太大	降低 `maxrate`（如 `8M`）或缩短时长
横版字幕太小	用 `assemble.py --size 1920x1080` 重新渲染
黑边	用默认 `blur` 模式或 `crop`

Frequently asked questions

What does the Platform Spec Export AI skill do?

Why use Platform Spec Export on TypingMind?

Because you install it once and use it with any model. Platform Spec Export 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 Platform Spec Export in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/xianyu110/ecommerce-video-skills/tree/main/skills/platform-spec-export. 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 Platform Spec Export?

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 Platform Spec Export?

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

Is the Platform Spec Export AI skill free?

Yes. It is published on GitHub by xianyu110 under the MIT 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.
