FAQPage Schema

How do I identify over-encapsulation and thin wrappers in TypeScript code?▼

To identify over-encapsulation and thin wrappers in TypeScript, run this Skill to detect code smells like thin helpers and unnecessary type splits. It analyzes modules to pinpoint readability issues and suggests concrete refactoring improvements.

What are common TypeScript code smells related to thin helpers and excessive abstraction?▼

Common TypeScript code smells include thin helpers, excessive abstraction, and instance properties mirroring parameters. These issues cause path jumping and reduced readability, which this Skill detects to enforce proper separation of concerns and stable types.

How do I refactor thin wrappers and consolidate types in JavaScript projects?▼

Refactor thin wrappers and consolidate types by applying this Skill's guidelines for inlining functions, merging thin layers, and simplifying parameter passing. This improves main flow readability and ensures proper separation of concerns during code reviews.

Does this code review tool follow project conventions defined in CLAUDE.md and AGENTS.md?▼

Yes, this code review tool follows project conventions by reading and adhering to repository specifications like CLAUDE.md and AGENTS.md before analysis. This ensures refactoring suggestions align with existing team guidelines and style compliance.

When should I preserve or merge thin wrappers during TypeScript refactoring?▼

When deciding to preserve or merge thin wrappers during TypeScript refactoring, this Skill applies specific guardrails to evaluate context. It checks JSDoc presence, parameter passing patterns, and separation of concerns to recommend safe consolidation.
