TypeScript

A prompt-based skill that provides a comprehensive TypeScript style guide. When the user mentions or implies TypeScript, this skill activates to generate standards-compliant TypeScript code and offer best-practice guidance.

Overview

This skill synthesizes and extends TypeScript coding conventions from multiple industry-leading style guides:

• clawhub.ai — TypeScript Guide
• mkosir — TypeScript Style Guide
• Platypi — TypeScript Style Guide

It covers 18 topic areas including naming conventions, types & interfaces, generics, error handling, async patterns, React/JSX, testing, and tooling configuration.

Activation

This is a natural language (prompt-based) skill. It activates automatically whenever the user says or implies TypeScript in conversation.

No special commands or syntax are required — just talk about TypeScript.

What It Does

Capability	Description
Code Generation	Generates TypeScript code that follows all style guide rules
Code Review	Analyses existing TypeScript code against the guide and suggests improvements
JS → TS Conversion	Converts JavaScript to idiomatic TypeScript with strict types
Best Practice Q&A	Answers questions about TypeScript conventions and patterns
Project Setup	Provides recommended tsconfig.json, ESLint, and Prettier configurations

Quick Start

Just ask a question or make a request involving TypeScript:

"Write a TypeScript function to validate email addresses"
"Review my TypeScript code for style issues"
"What's the best practice for TypeScript error handling?"
"Set up a new TypeScript project with strict mode"
"Convert this JavaScript class to TypeScript"

Style Guide Summary

The full guide is in SKILL.md. Here's a quick overview of the 18 sections:

#	Section	Key Points
1	General Principles	Strict mode, minimize any, immutability by default
2	Naming Conventions	camelCase for variables/functions, PascalCase for types/classes, no I prefix
3	Types & Interfaces	interface for objects, type for unions/intersections, use utility types
4	Enums	Prefer string enums or string literal unions, avoid numeric auto-increment
5	Variables & Constants	const by default, no var, prefer destructuring
6	Functions	Max 3 parameters, explicit return types, early returns, small functions
7	Classes	Composition over inheritance, explicit access modifiers, readonly properties
8	Modules & Imports	Named exports preferred, import type for types, grouped import order
9	Generics	Constrained generics, descriptive T-prefixed names for complex cases
10	Error Handling	Custom error classes, typed catch, Result pattern
11	Async / Await	async/await over .then(), Promise.all() for concurrency
12	Comments & Documentation	TSDoc for public APIs, no commented-out code
13	Formatting & Style	2-space indent, semicolons, single quotes, trailing commas
14	Null & Undefined	Optional chaining, nullish coalescing, strict null checks
15	Type Assertions & Guards	Type guards over assertions, discriminated unions
16	React & JSX	Functional components, interface for props, no React.FC
17	Testing	Arrange-Act-Assert, descriptive names, dependency injection
18	Tooling & Configuration	Recommended tsconfig.json, ESLint rules, Prettier config
