TypeScript Coding Standards (2026) — safe, modern, no legacy.

For AI Agents

Tell your AI agent to load the standards before coding:

/ts-all build a user authentication module
/ts-all refactor this function
/ts-all review this PR

Or load individual skills:

/ts-philosophy explain why any is banned
/ts-patterns show me branded types
/ts-jsdocs add JSDoc to this file
/ts-config-tooling generate a tsconfig
/ts-ai-behavior review my code

The AI will follow all rules: no any, no var, no legacy patterns, JSDoc on every export, branded types, discriminated unions, satisfies, as const, and strict TypeScript.

Quick Start

npm install
npx tsx src/main.ts     # run
npx tsc --noEmit        # type-check

Stack

Layer	Tool
Runtime	tsx (ESM)
Compiler	TypeScript tsc — target: esnext, strict: true
Types	@types/node
Module	ESM

Philosophy

• No any — every type is known at compile time.
• No var — const / let only.
• No legacy patterns — class-based OOP is out; pure functions, discriminated unions, and branded types are in.
• JSDoc on every export — AI agents and humans alike rely on clear docstrings.
• 2026 idioms — using, namespace-free, satisfies, as const everywhere.
