init-spec-md: SPEC-IT File Generator for Existing Code

Generate SPEC-IT-{HASH}.md metadata files for existing UI code to enable progressive context loading.

CRITICAL: Context Management Rules

반드시 shared/context-rules.md 규칙을 준수하세요.

핵심 규칙

규칙	제한	위반 시
배치 처리	10개 파일씩	메모리 초과 방지
에이전트 반환	요약만	내용 포함 금지
파일 읽기	필요한 것만	전체 스캔 금지

Purpose

Progressive Context Loading: Agents load only required context
Bidirectional Navigation: Parent ↔ Child document links
Registry Management: All HASHes managed in .spec-it-registry.json

Usage

/frontend-skills:init-spec-md                    # Full project scan
/frontend-skills:init-spec-md src/components     # Specific path only
/frontend-skills:init-spec-md --dry-run          # Preview (no file creation)
/frontend-skills:init-spec-md --force            # Overwrite existing files

Arguments

Argument	Description
`[path]`	Target directory (default: project root)
`--dry-run`	Preview mode, show what would be created
`--force`	Overwrite existing SPEC-IT files

Agents Used

spec-md-generator (haiku) - Create SPEC-IT files
spec-md-maintainer (haiku) - Update registry and links

HASH Generation Rules

Format: 8-character alphanumeric (e.g., A1B2C3D4)

Examples:
- SPEC-IT-A1B2C3D4.md (Button component)
- SPEC-IT-E5F6G7H8.md (LoginPage)
- SPEC-IT-I9J0K1L2.md (AuthModule)

Output Format

Component (component.tsx)

# SPEC-IT-A1B2C3D4

## Component: Button

### Description
Primary action button with loading state support.
- Click event handling
- Loading state display
- Disabled state support

### Props
| Prop | Type | Required | Description |
|------|------|----------|-------------|
| variant | 'primary' \| 'secondary' | N | Button style |
| loading | boolean | N | Loading state |

| onClick | () => void | Y | Click handler |

### Wireframe (ASCII)
┌─────────────────────────┐
│  [Icon]  Button Text    │  ← Normal
└─────────────────────────┘

┌─────────────────────────┐
│  [Spinner] Loading...   │  ← Loading
└─────────────────────────┘

Registry File Format

.spec-it-registry.json - Located at project root

Execution Instructions

Step 1: Parse Arguments

# 인자 파싱
targetPath = $1 || "."
dryRun = "--dry-run" in $ARGUMENTS
force = "--force" in $ARGUMENTS

Output: "대상 경로: {targetPath}, dry-run: {dryRun}, force: {force}"

Step 2: Scan Target Directory

# Glob으로 파일 스캔
Glob("{targetPath}/**/page.tsx")      → pages[]
Glob("{targetPath}/**/layout.tsx")   → layouts[]
Glob("{targetPath}/**/*[A-Z]*.tsx")  → components[] (export default 포함)
Glob("{targetPath}/**/*Module.ts")   → modules[]
Glob("{targetPath}/**/*Service.ts")  → services[]

# 제외 패턴
exclude = ["node_modules/**", ".next/**", "dist/**"]

# 기존 SPEC-IT 파일 확인 (--force 아니면 스킵)
IF NOT force:
  existingSpecs = Glob("{targetPath}/**/SPEC-IT-*.md")
  # 해당 폴더의 파일은 스킵

Step 3: 배치 처리로 SPEC-IT 생성

# 10개씩 배치로 처리 (컨텍스트 관리)
allFiles = pages + layouts + components + modules + services

FOR batch in chunks(allFiles, 10):
  Task(
    subagent_type: "general-purpose",
    model: "haiku",
    prompt: "
      역할: spec-md-generator

      입력 파일 목록:
      {batch}

      작업:
      1. 각 파일 분석 (Props, JSDoc, export 등)
      2. SPEC-IT-{HASH}.md 생성
      3. HASH = MD5(파일경로).substring(0,8).toUpperCase()

      출력: 각 파일과 같은 폴더에 SPEC-IT-{HASH}.md

      OUTPUT RULES:
      1. 파일에만 저장
      2. 반환 시 '생성됨: {경로}' 형식만
      3. 파일 내용 반환 금지
    "
  )

Step 4: Registry 업데이트

Task(
  subagent_type: "general-purpose",
  model: "haiku",
  prompt: "
    역할: spec-md-maintainer

    작업:
    1. .spec-it-registry.json 읽기 (없으면 생성)
    2. 새로 생성된 SPEC-IT 파일들 등록
    3. parent-child 관계 설정
    4. 통계 업데이트

    OUTPUT RULES: (요약만 반환)
  "
)

Step 5: 결과 보고

Output: "

  init-spec-md 완료

  생성됨: {created}개
    - Components: {components}개

Dry-Run Mode

--dry-run 사용 시:
- 파일 생성 없이 미리보기만
- 어떤 파일이 생성될지 목록 출력
- Registry 변경 없음
