The Six Skills in Detail

1. Humanizer-zh: 5600 ⭐ — The Original "AI Flavor" Remover

His most popular skill. Simply put: makes AI-written text sound more human.

The problem: AI text has an indescribable "fake" feel. Repetitive phrasing, three-part parallelism, always "此外" (moreover), "然而" (however), "不仅仅是……而是……" (not just… but…). Readers can't pinpoint the issue but feel it's not human-written.

How it works: Based on Wikipedia's "Signs of AI Writing" guide, identifies and fixes 24 AI patterns:

Overemphasis on meaning ("作为……的证明" as proof of…)

AI buzzwords ("此外", "至关重要", "深入探讨")

Rule of three ("无缝、直观和强大" seamless, intuitive, powerful)

Negative parallelism ("不仅仅是……而是……")

Overuse of em-dashes

Overuse of bold text

…

Usage: In Claude Code, type /humanizer-zh [your text]

Real example:

Input (AI flavor):
这个项目作为我们团队致力于创新的证明。此外，它展示了我们在不断演变的技术格局中的关键作用。

Output (humanized):
我们做了这个产品。测试用户反馈不错，大部分人说任务完成速度确实变快了。

2. NanoBanana-PPT-Skills: 2100 ⭐ — AI-Powered PPT Tool
The problem: Making PPT is tedious, finding templates is annoying, formatting is worse.
How it works: AI auto-generates high-quality PPT images and videos with smart transitions and interactive playback. Directly callable from Claude Code.

3. Claude-to-IM-skill: 1800 ⭐ — Connect AI Coding to Your Chat Apps
The problem: How to make AI write code when you're not at your computer?
How it works: Runs a background daemon connecting Telegram, Discord, Feishu to Claude Code/Codex. Message from your phone, AI coder responds—tool calls, permission requests, streaming previews all flow back to chat.
---
4. Youtube-clipper-skill: 1700 ⭐ — One-Click YouTube Video Processor
The problem: Found a good interview video, want to share with friends, but it's too long for anyone to watch.
How it works:
1. Download long YouTube videos
2. AI analyzes content
3. Gives "long to short" editing suggestions
4. Auto-adds Chinese and English subtitles
---
5. Document-illustrator-skill: 311 ⭐ — Auto-Illustrate Your Documents
The problem: Writing articles, need images but can't find suitable ones.
How it works: AI analyzes your document content, auto-generates 16:9 or 4:3 illustrations in multiple styles.
---
6. Video-Wrapper-Skills: 200 ⭐ — Variety Show Effects for Videos
The problem: Interview videos are boring, want to add effects like "小 Lin 说" (a popular Chinese finance YouTuber).
How it works: AI analyzes subtitles, generates highlight cards, keyword cards, author intros, social media cards—user approves, then auto-renders.
