typescript-pedantry

What problem does it solve?

This Skill enforces strict TypeScript best practices, preventing common bugs related to type safety, runtime validation, and code maintainability.

Core Features & Use Cases

• Strict Type Safety: Enforces strict: true in tsconfig.json and promotes discriminated unions over unsafe type assertions.
• Runtime Validation: Integrates Zod for validating data at system boundaries, ensuring type safety even with external inputs.
• Code Maintainability: Guides on using barrel exports, as const, and template literal types for cleaner, more robust code.
• Use Case: When refactoring a JavaScript codebase to TypeScript, or when encountering runtime errors due to type mismatches, this Skill provides the rules and patterns to write truly type-safe TypeScript.

Quick Start

Apply the typescript-pedantry skill to ensure all TypeScript code adheres to strict type-checking rules and uses discriminated unions for variant types.
