What problem does it solve?

This skill helps developers avoid unsafe type assertions by enforcing explicit type annotations in TypeScript, ensuring values conform to defined interfaces at compile time.

Core Features & Use Cases

• Type annotations validate values, function returns, and object literals against defined types.
• Discourages use of as type assertions that bypass checks; promotes safer, more maintainable code.
• When assertions are truly needed, provides guidelines and examples to document rationale and ensure safety.

Quick Start

Ask your codebase to replace type assertions with appropriate type annotations to enforce safety.
