Does it override my existing project style?

The skill treats these conventions as a baseline but prioritizes the project's existing 'voice,' such as CLAUDE.md files or established patterns in the repository.

Why does it prefer 'type' over 'interface'?

It favors 'type' for internal composition and algebraic types due to its flexibility, reserving 'interface' strictly for contracts with external consumers.

How does it handle function complexity?

It enforces a target of 20 lines or fewer per function and a maximum nesting depth of 3 levels to ensure code remains testable and easy to follow.

What languages does this skill support?

The skill is specifically optimized for TypeScript and JavaScript, though the core principles of clean code can be adapted to other languages.

開発者ツール

Enforces strict, opinionated coding standards and best practices for high-quality TypeScript and JavaScript development.

This skill equips Claude with a rigorous set of 'convictions' designed to eliminate ambiguity and technical debt in TypeScript and JavaScript projects. It mandates strict typing, immutability by default, and explicit access modifiers while enforcing clean code metrics like small function sizes and shallow nesting. By applying these non-negotiable standards to code generation and analysis, the skill ensures that every line of code is intentional, readable, and architecturally sound, prioritizing long-term maintainability over quick hacks.
