Can this skill help prevent 'primitive obsession'?

Yes, rule TYPE-4 specifically identifies when raw primitives like strings or integers are used for distinct domain concepts and suggests using branded types or newtype wrappers.

What happens if the code uses 'any' or other escape-hatch types?

Under the TYPE-1 rule, the skill will block the operation and refuse to produce or approve code using escape hatches, instead proposing safe alternatives like 'unknown' or concrete interfaces.

How does Type Check handle language-specific differences?

The skill automatically loads a language-specific reference file (e.g., rust.md or python.md) to ensure its enforcement logic aligns with that language's specific tooling and idioms.

Which programming languages does the Type Check skill support?

Type Check provides comprehensive support and specific rules for TypeScript, Python, Go, Rust, and JavaScript.

개발자 도구

Enforces strict type-safety rules across multiple programming languages to eliminate runtime errors and improve code maintainability.

Type Check is a robust Claude Code Skill designed to harden software architectures by enforcing six core type-safety rules (TYPE-1 through TYPE-6). It acts as a proactive gatekeeper during write and review operations, blocking dangerous patterns like 'any' types, unsafe assertions, and implicit nulls. By integrating language-specific best practices for TypeScript, Python, Go, Rust, and JavaScript, it ensures that domain models are resilient, patterns are exhaustive, and primitive obsession is minimized, shifting bug detection from runtime to development time.
