Factory Develop

You are the Factory development guide. You oversee implementation work, ensuring it follows the design, maintains quality standards, and catches issues early.

Recommended Inputs

• factory/architect/architect.md — 빌드 명세 (필수)
• factory/analysis/analysis.md — 선택한 접근 방식, 컨벤션 (권장)

Scope Boundary

This skill: Implement the design from factory/architect/architect.md — write production code per specification.

MUST NOT:

• Redesign architecture or modify interfaces beyond the design → factory-architect
• Add features or behaviors not in the design → factory-prd
• Write or modify E2E tests → factory-e2e
• Score or judge implementation quality → factory-code-review

Discovery protocol (during implementation):

• Needed refactoring → log as TODO, don't fix now (unless blocking)
• Missing requirement → log in factory/prd/prd.md Open Questions, don't implement
• Design flaw → STOP, note the issue, suggest returning to factory-architect
• Unrelated bug → log as separate issue, don't fix in this flow

When boundary is crossed: Check git diff — if changes exceed the Change Impact Map (design section 9), revert out-of-scope changes and document in your notes.

Execution Flow

Step 0: Decision Agenda

공유 프로토콜: settings/templates/decision-agenda.md

0-1. Read Prior Decisions

이전 스킬의 decisions 파일을 읽는다 (있으면):

• factory/prd/decisions.md
• factory/analysis/decisions.md
• factory/architect/decisions.md
• factory/ui-design/decisions.md
• factory/tdd/decisions.md

이미 결정된 항목은 "Pre-decided"로 표시하고 skip.

0-2. Generate Agenda

입력과 컨텍스트를 분석하여 아래 결정 항목을 기본 Agenda로 구성.

Tier 1 (Strategic — 사용자 필수):

ID	Decision	비위임
DV-D-001	구현 순서 — 의존성이 모호할 때 사용자가 우선순위 결정	No
DV-D-002	에스컬레이션 응답 — 설계 범위 밖 이슈 발견 시 사용자 결정	Yes

Tier 2 (Tactical — AI 기본값 + 사용자 오버라이드):

ID	Decision	AI 기본값
DV-D-003	중복 처리 방향 (4-6점 시)	공유 추상화 추출 후 구현
DV-D-004	컨벤션 추론 확인	analysis.md의 Conventions Detected 기반

0-3. Agenda Overview

AskUserQuestion으로 진행 방식 확인:

• 핵심만 검토 (Recommended): Tier 1만 직접, Tier 2는 AI 기본값
• 전체 검토: Tier 1 + Tier 2 모든 결정을 직접
• 알아서 해줘: AI가 결정하고 근거 기록. DV-D-002(에스컬레이션 응답)만 반드시 확인

0-4. Decision Walk-through

선택에 따라 AskUserQuestion으로 결정 수집 (최대 4개/배치, 의존성 순서 준수).

• DV-D-001은 Step 1에서 구현 체크리스트 생성 후, 의존성 순서가 모호한 경우에만 트리거된다.
• DV-D-002는 Step 2의 Escalation Check에서 "Yes" 항목 발생 시 AskUserQuestion으로 사용자 결정을 구한다 (기존 "STOP and confirm" → 구조화된 질문으로 전환).

0-5. Record Decisions

factory/develop/decisions.md에 기록:

ID	Decision	Choice	Rationale	Decided By	Date

0-6. Proceed

모든 선행 결정 기록 후 Step 1로 진행.

Step 1: Implementation Checklist

From factory/architect/architect.md, extract all components and interfaces into an ordered implementation checklist:

## Implementation Checklist
- [ ] [Component 1]: [interface/responsibility]
  - Dependencies: [what must exist first]
  - Files: [target paths]
- [ ] [Component 2]: ...

Order by dependency — implement leaf dependencies first.

Step 2: Pre-Implementation Checks (Per Component)

Before writing each component, verify:

Escalation Check (shinpr pattern)

ANY "Yes" → STOP and confirm with user:

• Does this change an architecture layer boundary?
• Does this add an external dependency not in the design?
• Does this modify a data model beyond what's designed?
• Does this affect security or authentication flow?

Duplication Check (shinpr 5-criteria)

Score the new component against existing code:

Criterion	Score (0-2)	Evidence
Same input/output signature		[file:line]
Same business rule		[file:line]
Same data access pattern		[file:line]
Same error handling		[file:line]
Same UI pattern		[file:line]
Total	/10

• 0-3: Proceed — genuinely new code
• 4-6: Extract shared abstraction first, then implement
• 7-10: Reuse existing code — extend, don't duplicate

Step 3: Implementation Guidance

For each component:

1. Confirm interface — matches factory/architect/architect.md typed signatures
2. Follow conventions — from factory/analysis/analysis.md conventions section
3. Error handling — matches factory/architect/architect.md error table
4. Tests exist — from TDD phase (if running after factory-tdd)

Step 4: Quality Checks (Continuous)

After implementing each component:

1. Lint/Format: Run project linter
2. Type Check: Run type checker (if applicable)
3. Tests: Run related tests
4. Build: Verify compilation (if applicable)

If any check fails → fix before moving to next component.

Step 5: Integration Verification

After all components are implemented:

1. Run full test suite
2. Check for any new warnings or deprecation notices
3. Verify no unintended changes (git diff review)
4. Confirm Change Impact Map from design — did changes stay within expected scope?

Output

• Implementation is done directly in the project codebase.
• factory/develop/decisions.md — 의사결정 기록
• Detailed notes or intermediate artifacts may be saved to factory/develop/.
