.claude/skills/refactor/SKILL.md

refactor is a skill for Claude Code from whchoi98/seoul-opendata-mcp. It costs 0 tokens per session (226 once invoked), scanned A, original, MIT.

Instructions for improving code structure without changing what the program does. It emphasizes small changes, less duplication, and testing.

In plain words
What is it for?
Use it to analyze dependencies, plan a refactor, make incremental edits, and verify the existing tests.
Why use it?
It provides a safe process for making code easier to understand and maintain while checking that behavior stays the same.

Skill for Claude Code

Written for Claude Code: installed under .claude/.

This is whchoi98/seoul-opendata-mcp's own configuration. It tells Claude Code how to work on seoul-opendata-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything seoul-opendata-mcp configures →

Reuse

Borrowing it

Nothing to install: this file belongs to whchoi98/seoul-opendata-mcp. Take a copy, put it at the same path in your own repository, and replace the rules that are about this project with yours.

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

refactor 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 10d 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.

What it actually says

Refactor Skill

동작 변경 없이 기존 코드의 품질을 개선하기 위해 리팩터링합니다.

원칙

  • 동작 변경 없이 구조 개선
  • 단일 책임 원칙(SRP)
  • 중복 코드 제거(DRY)
  • 검증 가능한 작은 증분 단계

프로세스

1. 분석

  • 대상 코드 및 관련 테스트 파악
  • 모든 호출자 및 의존성 매핑
  • 테스트 커버리지 확인 (테스트가 없으면 먼저 추가 제안)

2. 계획

리팩터링 계획을 사용자에게 제시하십시오:

  • 변경될 내용
  • 변경되지 않을 내용 (동작 보존)
  • 위험도 평가 (낮음/중간/높음)

3. 실행

  • 작은 검증 가능한 단계로 변경 수행
  • 가능한 경우 각 단계 후 테스트 실행
  • 원자적 커밋 유지

4. 검증

  • 모든 기존 테스트 통과 확인
  • 동작 변경 없음 확인
  • 리팩터링이 목표 달성 확인

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.

refactor is a skill published in the GitHub repository whchoi98/seoul-opendata-mcp (1 stars, last pushed 25d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 226 tokens. 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.
