  • 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.

  • 7 bundled files

    Scripts, templates, and references the model can read while it works. Files are read-only and never executed.

  • Open source

    Published by wechat-miniprogram on GitHub. Read the source before you install it.

Installation

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

1

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.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
    https://github.com/wechat-miniprogram/skyline-skills/tree/master/skills/skyline-worklet
  4. 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/wechat-miniprogram/skyline-skills.git /tmp/skyline-skills
mkdir -p .claude/skills
cp -r /tmp/skyline-skills/skills/skyline-worklet .claude/skills/skyline-worklet
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Skyline Worklet 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 Skyline Worklet 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 Skyline Worklet 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.

Worklet 动画系统

适用场景

  • 实现手势跟随、拖拽等交互动画
  • 使用 timing/spring/decay 创建动画效果
  • 通过 SharedValue 驱动节点样式变化
  • 组合多段动画(序列、重复、延迟)
  • 在 UI 线程和 JS 线程间传递数据

核心概念

双线程架构与 Worklet 的意义

小程序双线程架构中,UI 事件需跨线程传递到 JS 线程再回传,交互动画会有明显延迟。Worklet 动画让动画逻辑直接运行在 UI 线程,实现类原生动画体验。

三大核心概念

概念说明关键 API
worklet 函数可运行在 JS 或 UI 线程的函数,顶部声明 'worklet' 指令runOnUI(), runOnJS()
共享变量跨线程同步的变量,通过 .value 读写shared(), derived()
动画驱动将 SharedValue 绑定到节点样式applyAnimatedStyle()

基本流程

js
const { shared, timing } = wx.worklet

// 1. 创建共享变量
const offset = shared(0)

// 2. 绑定到节点样式(updater 为 worklet 函数)
this.applyAnimatedStyle('#box', () => {
  'worklet'
  return { transform: `translateX(${offset.value}px)` }
})

// 3. 修改值驱动动画
offset.value = timing(300, { duration: 200 })

文档索引

根据需求快速定位(路径相对于 references/):

我想要...查阅文档
了解 worklet 架构和完整概念core/worklet-overview.md
使用 SharedValue 和 DerivedValuebase/shared-derived.md
在 worklet 中操作 scroll-viewbase/scroll-view-context.md
使用 timing/spring/decay 动画animation/timing-spring-decay.md
查看 Easing 缓动函数animation/easing.md

强制规则

MUST: worklet 函数必须声明 'worklet' 指令

js
// ✅ Correct
function handleGesture(evt) {
  'worklet'
  offset.value += evt.deltaX
}

// ❌ Incorrect - 缺少 'worklet' 指令,无法在 UI 线程执行
function handleGesture(evt) {
  offset.value += evt.deltaX
}

MUST: SharedValue 必须通过 .value 读写

js
// ✅ Correct
const offset = shared(0)
offset.value = 100

// ❌ Incorrect - 直接赋值会替换整个 SharedValue 对象
const offset = shared(0)
offset = 100

MUST: 访问非 worklet 函数必须使用 runOnJS

js
// ✅ Correct
function showModal(msg) {
  wx.showModal({ title: msg })
}
function handleTap() {
  'worklet'
  const fn = this.showModal.bind(this)
  runOnJS(fn)('hello')
}

// ❌ Incorrect - worklet 中直接调用普通函数
function handleTap() {
  'worklet'
  this.showModal('hello')
}

MUST: 页面方法必须通过 this.methodName.bind(this) 访问

js
// ✅ Correct
handleTap() {
  'worklet'
  const showModal = this.showModal.bind(this)
  runOnJS(showModal)(msg)
}

// ❌ Incorrect - 未 bind(this),this 指向丢失
handleTap() {
  'worklet'
  runOnJS(this.showModal)(msg)
}

MUST: Worklet 动画仅在 Skyline 渲染模式下可用

  • 确保 app.json 配置 "renderer": "skyline"
  • 确保开发者工具勾选「将 JS 编译成 ES5」

NEVER: 在 worklet 函数中直接调用 wx API

必须通过 runOnJS 回到 JS 线程。

NEVER: 通过解构 this.data 访问属性

会导致 Object.freeze 冻结 this.data,setData 将失效。

js
// ✅ Correct
handleTap() {
  'worklet'
  const msg = this.data.msg
}

// ❌ Incorrect - 解构会冻结整个 this.data
handleTap() {
  'worklet'
  const { msg } = this.data
}

Why use Skyline Worklet on TypingMind?

Because you install it once and use it with any model. Skyline Worklet 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 Skyline Worklet in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/wechat-miniprogram/skyline-skills/tree/master/skills/skyline-worklet. 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 Skyline Worklet?

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 Skyline Worklet?

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

Is the Skyline Worklet AI skill free?

Yes. It is published on GitHub by wechat-miniprogram 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.
