purplemux: Skill for Claude Code

.claude/skills/2-draft/SKILL.md

2-draft is a skill for Claude Code from subicura/purplemux. It costs 0 tokens per session (746 once invoked), scanned A, original, MIT.

A skill for drafting feature specifications in a file named spec.md. It can create a specification for one named page or for all pages listed in the project's product requirements document.

In plain words
What is it for?
Use it to create versioned page specifications with scope, features, related documents, dependencies, and a change history.
Why use it?
It turns project requirements and documentation into a consistent first draft, reducing the work of planning each page from scratch.

Skill for Claude Code

This is subicura/purplemux's own configuration. It tells Claude Code how to work on purplemux 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 purplemux configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is - [화면 구성](./detail/ui.md).

Reuse

Borrowing it

Nothing to install: this file belongs to subicura/purplemux. 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

2-draft 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 8d 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

spec-draft — 스펙 초안 작성

기능 스펙 초안(spec.md)을 작성합니다. 페이지명 지정 시 해당 페이지만, 미지정 시 전체 일괄 생성합니다. "v1 스펙 초안", "v1 전체 스펙 초안" 요청 시 사용합니다.

Instructions

다음 단계를 순서대로 수행하세요.

1. 버전 확인

  • 사용자가 버전을 지정한 경우 해당 버전 사용 (예: v1, v2)
  • 미지정 시 현재 진행 중인 버전 사용

2. 요구사항 파악

  • .specs/v{N}/PRD.md를 읽어 요구사항 파악

3. 프로젝트 가이드 파악

  • CLAUDE.md의 "참고 문서" 섹션에서 docs/ 가이드 목록 파악

4. 대상 결정

  • 페이지명 지정 → 해당 페이지만 생성
  • 미지정PRD.md의 페이지 목록 기반으로 전체 일괄 생성

5. spec.md 생성

.specs/v{N}/features/{feature-name}/spec.md를 다음 구조로 생성합니다:

---
page: { page-name }
title: { 페이지 제목 }
route: { 라우트 경로 }
status: DRAFT
complexity: Low | Medium | High
depends_on:
  - docs/{관련 가이드}.md
created: { 날짜 }
updated: { 날짜 }
assignee: ''
---

# {페이지 제목}

## 개요

(페이지 목적과 범위)

## 주요 기능

- 기능 항목들

## 하위 문서

- [화면 구성](./detail/ui.md)
- [사용자 흐름](./detail/flow.md)
- [API 연동](./detail/api.md)

## 변경 이력

| 날짜   | 변경 내용 | 상태  |
| ------ | --------- | ----- |
| {날짜} | 초안 작성 | DRAFT |

6. depends_on 연결

  • 페이지와 관련된 프로젝트 가이드(docs/)를 depends_on에 연결

7. 일관성 유지

  • 기존에 작성된 페이지 스펙이 있으면 스타일을 참고하여 일관성 유지

8. 품질 기준 적용

각 페이지의 주요 기능을 아래 세 축으로 검증하고, 부족한 부분을 spec.md에 반영합니다:

  • 빠르다 — 주요 기능 중 성능 전략이 필요한 항목을 식별하고 기능 목록에 포함 (prefetch, 캐싱, 지연 로딩 등)
  • 토스급 완성도 — 로딩·빈·에러 상태 처리, 인터랙션 피드백, 전환 애니메이션 등 UX 완성도 항목을 기능에 포함. "동작만 하는" 수준의 기능 정의는 허용하지 않음
  • 포브스 TOP 10 기업 수준 — 기능 하나하나가 실무에서 바로 쓸 수 있는 깊이인지 검증. "되긴 되는" 수준이 아닌 "이 정도면 감탄한다" 수준을 목표로 기능 정의

9. 다음 단계 안내

작성 완료 후 다음 안내 메시지를 반드시 출력:

각 feature의 spec.md를 검토한 뒤, frontmatter의 status를 CONFIRMED로 변경하세요.
CONFIRMED된 feature만 `/3-detail`과 `/4-build`에서 처리됩니다.

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.
