precise-any-variants

What problem does it solve?

This skill helps developers manage the unsafe and overly broad use of TypeScript's any type by guiding them toward precise variants that preserve type safety.

Core Features & Use Cases

• Recommends specific variants for common scenarios: use any[] for arrays, Record<string, any> for objects, and () => any for functions to retain structure while accommodating dynamic data.
• Encourages safer alternatives like unknown for truly unknown data and provides concrete examples across data parsing, API integration, and dynamic data handling.
• Helps teams maintain consistent typing discipline during migrations from JavaScript or dynamic sources, reducing runtime errors and improving maintainability.

Quick Start

Choose the most specific any variant for the given use case and annotate your function signatures accordingly.
