TypeComposer Skill for AI Coding Agents

A Skills.sh-compatible AI coding-agent skill for developers building TypeComposer applications and components.

Install

npx skills add TypeComposer/skill

What this skill helps with

Once installed, any Skills.sh-compatible AI agent gains deep, accurate knowledge of TypeComposer's APIs so it can:

TaskWhat the agent does
Scaffold new componentsGenerates TypeScript class-based components with correct onInit lifecycle and element imports — no JSX/HTML templates
Layout compositionUses VBox, HBox, BorderPanel, GridPanel, FlowPanel, ScrollPanel, StackPanel, and other layout primitives correctly
Reactive stateUses ref(), typed ref variants (RefString, RefNumber, RefBoolean, RefList, RefMap, RefSet, RefState), and Computed with proper subscription and cleanup patterns
RoutingConfigures Router.create() with RoutePage[], RouterGuard, nested routes, dynamic params, and Router.go() navigation
Dependency injectionApplies @Service / @Inject decorators with InjectedType scope options
Composing with built-in elementsUses ButtonElement, H1Element, ImageElement, SpanElement, and the full typed element catalogue from typecomposer
Anti-pattern avoidancePrevents JSX mental-model leakage, unsafe innerHTML for user content, and ad-hoc DOM trees where TypeComposer primitives exist
App bootstrappingUses App.setPage() correctly, understands Router lifecycle integration

Quick start

npm create typecomposer@latest

Minimal TypeComposer app

// main.tsimport{App,BorderPanel,VBox,H1Element,ButtonElement}from"typecomposer";exportclassMyPageextendsBorderPanel{privatecount=0;onInit(): void{constvbox=newVBox({justifyContent: "center",alignItems: "center"});vbox.append(newH1Element({text: "Hello TypeComposer"}));constbtn=newButtonElement({text: "Click me"});btn.onclick=()=>{this.count++;btn.text=`Clicked ${this.count}×`;};vbox.append(btn);this.center=vbox;}}App.setPage(newMyPage());

TypeComposer Skill for AI Coding Agents
A Skills.sh-compatible AI coding-agent skill for developers building TypeComposer applications and components.
Install
npx skills add TypeComposer/skill
What this skill helps with
Once installed, any Skills.sh-compatible AI agent gains deep, accurate knowledge of TypeComposer's APIs so it can:
TaskWhat the agent does
Scaffold new componentsGenerates TypeScript class-based components with correct onInit lifecycle and element imports — no JSX/HTML templates
Layout compositionUses VBox, HBox, BorderPanel, GridPanel, FlowPanel, ScrollPanel, StackPanel, and other layout primitives correctly
Reactive stateUses ref(), typed ref variants (RefString, RefNumber, RefBoolean, RefList, RefMap, RefSet, RefState), and Computed with proper subscription and cleanup patterns
RoutingConfigures Router.create() with RoutePage[], RouterGuard, nested routes, dynamic params, and Router.go() navigation
Dependency injectionApplies @Service / @Inject decorators with InjectedType scope options
Composing with built-in elementsUses ButtonElement, H1Element, ImageElement, SpanElement, and the full typed element catalogue from typecomposer
Anti-pattern avoidancePrevents JSX mental-model leakage, unsafe innerHTML for user content, and ad-hoc DOM trees where TypeComposer primitives exist
App bootstrappingUses App.setPage() correctly, understands Router lifecycle integration
Quick start
npm create typecomposer@latest
Minimal TypeComposer app
// main.tsimport{App,BorderPanel,VBox,H1Element,ButtonElement}from"typecomposer";exportclassMyPageextendsBorderPanel{privatecount=0;onInit(): void{constvbox=newVBox({justifyContent: "center",alignItems: "center"});vbox.append(newH1Element({text: "Hello TypeComposer"}));constbtn=newButtonElement({text: "Click me"});btn.onclick=()=>{this.count++;btn.text=`Clicked ${this.count}×`;};vbox.append(btn);this.center=vbox;}}App.setPage(newMyPage());
