How does this skill improve TypeScript safety?

It scans your code for unsafe patterns like 'any' or forced assertions and suggests safer alternatives such as type guards and 'unknown' types.

Does it support exhaustive checking?

Yes, it identifies non-exhaustive switch statements and recommends using the 'assertNever' pattern to ensure all possible cases are handled at compile time.

Can it help with strict mode migration?

Yes, it is specifically designed to help projects reach 100% strict mode compliance by identifying missing type annotations and unhandled null cases.

What is the target type coverage for this skill?

The skill benchmarks code against a target of 95% or higher type coverage and aims for zero instances of the 'any' keyword.

Developer Tools

Reviews TypeScript code to eliminate unsafe patterns and ensure maximum type coverage.

About

This skill acts as a specialized auditor for TypeScript projects, enforcing strict type safety standards to prevent runtime errors. It automatically identifies common pitfalls such as the use of 'any', unsafe type assertions, and non-null assertions, providing specific refactoring patterns to move towards 100% type coverage. It is particularly useful during code reviews, refactoring sessions, or when migrating legacy codebases to strict TypeScript configurations.

Key Features

Enforces explicit function parameter and return type annotations
3 GitHub stars
Detects and replaces 'any' types with 'unknown' and robust type guards
Identifies unsafe type assertions and non-null assertions to suggest explicit checks
Verifies exhaustive pattern matching in switch statements using assertNever
Analyzes code to help achieve a minimum of 95% type coverage

Use Cases

Migrating legacy TypeScript projects to strict mode for better reliability
Optimizing type definitions in mission-critical applications to prevent runtime crashes
Automating code quality audits during the development and review process
