explicit-parameters

explicit-parameters is a skill for Claude Code from msbaek/msbaek-claude-plugins. It costs 132 tokens per session (1,656 once invoked), scanned A, original, MIT.

A code-refactoring method that replaces hidden dependencies, such as global variables or class fields, with values passed directly into functions or methods.

In plain words
What is it for?
Use it when changing functions or methods so their inputs are visible and easier to test or reuse.
Why use it?
It makes it clearer where a piece of data comes from and reduces behaviour that depends on unseen shared state.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

explicit-parameters scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 174 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Explicit Parameters

GOAL

암묵적 의존성(전역변수, 클래스 필드, Singleton)을 명시적 파라미터로 전환하여:

  • 함수 시그니처로 의존성을 명확히 표현
  • 테스트 용이성 향상 (의존성 주입 가능)
  • 숨겨진 결합도 제거

CONSTRAINTS

  • 계열: System-wide — 후보 제시 후 승인 받고 적용 (../../references/refactoring-procedure.md §0·§3-B)
  • 동작 변경 금지: 구조 개선만 수행 (기능 변경 없음)
  • 테스트 수정 금지: 구조 변경이 테스트를 실패시키면 되돌리기
  • 사용자 확인 필수: 자동 적용 금지
  • 명시적 git add: git add -A 금지, 변경된 파일만 명시

적용 패턴

Before: 필드에 암묵적 의존

class OrderService {
    private DiscountPolicy discountPolicy;
    private TaxCalculator taxCalculator;
    
    double calculateTotal(Order order) {
        double discount = discountPolicy.calculate(order.getSubtotal());
        double tax = taxCalculator.calculate(order.getSubtotal() - discount);
        return order.getSubtotal() - discount + tax;
    }
}

After: 명시적 파라미터

class OrderService {
    double calculateTotal(Order order, DiscountPolicy discountPolicy, TaxCalculator taxCalculator) {
        double discount = discountPolicy.calculate(order.getSubtotal());
        double tax = taxCalculator.calculate(order.getSubtotal() - discount);
        return order.getSubtotal() - discount + tax;
    }
}

추가 예시: Singleton 의존성 제거

// Before: 전역 상태 참조
double applyRate() {
    return amount * CurrencyConverter.getInstance().getRate("USD");
}

// After: 명시적 파라미터
double applyRate(CurrencyConverter converter) {
    return amount * converter.getRate("USD");
}

파라미터 과다 시: Introduce Parameter Object

// 파라미터 3개 이상 시
class OrderService {
    double calculateTotal(Order order, PricingContext context) {
        double discount = context.getDiscountPolicy().calculate(order.getSubtotal());
        double tax = context.getTaxCalculator().calculate(order.getSubtotal() - discount);
        return order.getSubtotal() - discount + tax;
    }
}

class PricingContext {
    private final DiscountPolicy discountPolicy;
    private final TaxCalculator taxCalculator;
    // constructor, getters...
}

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

explicit-parameters is a skill published in the GitHub repository msbaek/msbaek-claude-plugins (8 stars, last pushed 5d ago), licensed MIT. It adds 132 tokens to every session and 1,656 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
