Why does the skill discourage the use of nullish coalescing chains?

It promotes a 'Fail-fast' philosophy where the code throws explicit, context-rich errors immediately rather than providing silent fallbacks that can hide underlying bugs.

How does this skill handle TypeScript type safety?

It strictly forbids type escape hatches like 'any', 'as', and '@ts-ignore', instead guiding the user toward type-safe alternatives like discriminated unions and runtime validation.

Can this skill help with code refactoring?

Yes, it specifically identifies 'feature envy'—where a function is too obsessed with another object's data—and suggests ways to move logic into rich domain models.

What is the 8-dimension design analysis protocol?

It is a systematic framework used by the skill to evaluate code across naming, coupling, cohesion, immutability, domain integrity, and three other critical design markers for a comprehensive quality report.

Herramientas para Desarrolladores

Enforces robust software architecture patterns like fail-fast logic, immutability, and domain-driven design to eliminate technical debt.

Acerca de

This skill provides a rigorous framework for software design that transcends simple syntax checking. It equips Claude with a specific set of high-level architectural principles, such as favoring explicit dependencies over hidden ones, utilizing immutable data patterns, and ensuring illegal states are unrepresentable through discriminated unions. It is particularly valuable for developers aiming to standardize their codebase around clean TypeScript patterns and for performing systematic architectural audits via its built-in 8-dimension design analysis protocol.
