SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

このスキルは、Zodを用いたスキーマファーストの型定義を推奨し、interface/typeの直接記述やasによる型アサーションを禁止することで、型安全性と保守性を向上させます。

Core Features & Use Cases

Schema-first typing: Zodスキーマを用いて型を定義し、コード全体で一貫した型安全性を促進します。
No direct interface/type declarations: interfaceやtypeを直接書くことを制限して、スキーマから型を導出する慣例を維持します。
No type assertions: asを用いた型アサーションを避け、すべての型検証をスキーマで実施します。

Quick Start

新しい型やスキーマを定義する際は、直接interface/typeを記述せず、Zodスキーマを用いて型を定義してください。

FAQPage Schema

How do I enforce type safety in TypeScript using a schema-first approach?▼

Enforcing type safety with a schema-first approach means defining types via Zod schemas, preventing direct interface declarations and forbidden type assertions to maintain validated type definitions across codebases.

Why should I avoid direct interface and type declarations in TypeScript?▼

Avoiding direct interface and type declarations ensures all types derive from Zod schemas, maintaining consistent schema-first conventions and improving type safety and maintainability across your TypeScript project.

What is the best way to prevent type assertions in a TypeScript codebase?▼

Preventing type assertions is best achieved by replacing as keyword usage with Zod schema validations, enforcing all type checks through schemas to ensure consistent and validated type definitions.

Can I use Zod schemas to derive all TypeScript types instead of writing types manually?▼

Yes, using Zod schemas to derive TypeScript types prevents manual interface writing and type assertions, enforcing consistent schema-first conventions and validated type definitions across your codebase.

Does schema-first typing with Zod work for large TypeScript projects?▼

Schema-first typing with Zod works for large TypeScript projects by enforcing consistent, validated type definitions across codebases, restricting direct interface declarations and type assertions to maintain type safety.

When do I need schema-first conventions for TypeScript type safety?▼

You need schema-first conventions when you want to enforce type safety in TypeScript projects, preventing direct type declarations and type assertions by deriving all types from Zod schemas.
