Can it help me reach 100% type coverage?

While it targets a baseline of 95%, it provides the specific patterns and refactoring steps needed to push your project toward maximum coverage.

How does this skill handle the 'any' type in TypeScript?

It identifies instances of 'any' and suggests using 'unknown' combined with runtime type guards to maintain type safety without losing flexibility.

What tools does this skill use to analyze code?

The skill utilizes tools like Read, Grep, and Glob to scan your repository for unsafe patterns and missing type annotations.

Does it support exhaustive check patterns for switch statements?

Yes, it identifies 'default' cases that lack exhaustive checking and recommends implementing an 'assertNever' pattern to ensure all cases are handled.

개발자 도구

Audits TypeScript codebases to eliminate unsafe patterns and maximize type coverage through rigorous static analysis.

소개

The Reviewing Type Safety skill empowers Claude to perform deep audits of TypeScript projects, focusing on identifying and rectifying common type safety pitfalls. It scans for problematic patterns such as the use of 'any', unsafe type assertions, and non-null assertions, offering specific refactoring suggestions like implementing type guards or exhaustive switch checks. Designed for developers aiming for high-integrity code, this skill helps teams achieve a target type coverage of 95% or higher while ensuring strict mode configurations are fully utilized.
