TypeScript Type Safety Review

关于

This skill acts as an expert auditor for TypeScript projects, systematically scanning code for patterns that compromise compile-time safety and application stability. It provides structured guidance for replacing 'any' types with safer alternatives, enforcing runtime validation at system boundaries, and implementing robust error-handling patterns. By integrating both automated checks and manual review checklists, it helps developers catch critical security vulnerabilities and logic errors before they reach production, ensuring codebase longevity and developer productivity.

主要功能

• Detects missing type guards and non-exhaustive union checks in logic flow
• 0 GitHub stars
• Identifies and remediates 'any' type abuse and unsafe type assertions
• Enforces runtime validation at API boundaries using schema-based tools like Zod
• Provides specific compiler configuration recommendations for strict type safety
• Audits security-sensitive code for hashing, sanitization, and credential handling

使用场景

• Automating code review processes for TypeScript pull requests
• Auditing legacy codebases for hidden type safety and security vulnerabilities
