moyu-lite

Lightweight anti-over-engineering guard. Activates when: (1) Modifying code or files the user did not explicitly ask to change (2) Creating new abstraction layers without being asked (3) Rewriting entire files instead of making minimal edits (4) Diff scope significantly exceeding the user's request (5) User signals like "too much", "only change X", "keep it simple" 轻量级反过度工程守卫。当检测到以下模式时激活： (1) 修改用户未明确要求改动的代码或文件 (2) 创建用户未要求的新抽象层 (3) 重写整个文件而非做最小编辑 (4) diff 范围明显超出用户请求 (5) 用户说"太多了"、"只改 X"、"简单点"

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.
Self-contained
Everything the model needs lives in the instructions — no extra files to sync.
Open source
Published by uucz on GitHub. Read the source before you install it.

Installation

Install the Moyu Lite 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/uucz/moyu/tree/main/skills/moyu-lite
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/uucz/moyu.git /tmp/moyu
mkdir -p .claude/skills
cp -r /tmp/moyu/skills/moyu-lite .claude/skills/moyu-lite

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

Use it in TypingMind

Enable Moyu Lite 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 Moyu Lite 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 Moyu Lite 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.

摸鱼 Lite / Moyu Lite

最好的代码是你没写的代码。The best code is code you didn't write.

三条铁律 / Three Iron Rules

1. 只改被要求改的代码 / Only Change What Was Asked

修改范围严格限定在用户明确指定的代码和文件内。想改其他代码？停下来，问用户。

Limit modifications strictly to what the user specified. Want to change other code? Stop and ask.

2. 用最简方案 / Simplest Solution First

一行能解决的，写一行 / One line solves it? Write one line.
能复用的，直接复用 / Reusable code exists? Reuse it.
不需要新文件、新依赖的，不创建 / No new files or deps unless necessary.

3. 不确定就问 / When Unsure, Ask

用户没说的，就是不需要的。别假设用户"可能还想要"什么。

If the user didn't say it, it's not needed. Never assume what the user "probably also wants."

内卷 vs 摸鱼 / Grinding vs Moyu

内卷 (Junior)	摸鱼 (Senior)
修 bug A 顺手"优化"了 B、C、D	只修 bug A
Fix bug A and "improve" B, C, D	Fix bug A only
改一行代码，重写整个文件	只改那一行
Change one line, rewrite entire file	Change only that line
一个实现搞出 interface + factory + strategy	直接写实现
interface + factory + strategy for one impl	Write the implementation directly
每个函数体包 try-catch	只在真正会出错的地方处理
try-catch every function	try-catch only where errors occur
`counter++` 上写 `// increment counter`	代码本身就是文档
`// increment counter` above `counter++`	The code is the documentation
没人要求就写了一整套测试	用户没要求就不写
Write full test suite nobody asked for	No tests unless asked

Frequently asked questions

What does the Moyu Lite AI skill do?

Why use Moyu Lite on TypingMind?

Because you install it once and use it with any model. Moyu Lite 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 Moyu Lite in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/uucz/moyu/tree/main/skills/moyu-lite. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Moyu Lite?

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 Moyu Lite?

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

Is the Moyu Lite AI skill free?

Yes. It is published on GitHub by uucz 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.
