Design Handoff

⚠️ 개발 런타임 전용 — 이 스킬은 MoAI-ADK(Claude Code) 환경을 전제한다. Claude Cowork(Desktop)에서는 .moai/config 의존으로 동작하지 않을 수 있다. Desktop 사용자는 moai-designer:design-handoff-reader를 사용한다.

Design Handoff Domain Specialist

Assembles the 5-file Claude Design handoff package for the design-workflow Path A workflow (the handoff-deliverable step). The package is designed for paste-and-go use in the external claude.com Design product.

Quick Reference

The handoff package lives at .moai/design/handoff/:

Key guarantees:

• [HARD] prompt.md contains NO MoAI-specific tokens (no SPEC-, .moai/, manager-, internal skill names)
• [HARD] Brand voice integrated when .moai/project/brand/brand-voice.md exists
• [HARD] Brand-absent fallback: Brand Voice (default — please customize) placeholder section
• [HARD] Handoff exits with AskUserQuestion offering 3 options (a/b/c per the relevant requirement)
• [HARD] All 5 files produced regardless of brand context availability

Handoff Package Assembly

Input

• Bundle summary from design-handoff-reader (the preceding Path A step) — what the user wants designed, target users, value propositions
• Brief from design-brief when the request originates from a design brief (Lean Canvas / evaluation context)
• Optional: .moai/project/brand/brand-voice.md (brand context)
• Optional: .moai/project/brand/visual-identity.md (design tokens, colors)

Step 0: Brand Context Detection

Before writing any file, check brand context:

IF .moai/project/brand/brand-voice.md exists AND is non-empty:
  Load brand voice → use in Brand Voice section of prompt.md
  SET brand_present = true
ELSE:
  Use default brand voice placeholder
  SET brand_present = false
  Note: will include AskUserQuestion offer to run brand interview

Step 1: Assemble prompt.md

prompt.md MUST follow this exact 5-section structure:

1. Goal — 2-3 sentences describing what needs to be designed, target users, top 3 value propositions from the bundle summary / brief UVP
2. References — 3-5 URLs to existing products with style notes, plus key aesthetic direction
3. Brand Voice — Two branches (brand_present vs brand_absent), see decision below
4. Acceptance Criteria — Concise non-negotiable requirements list (5-8 items)
5. Out of Scope — Explicit exclusions (3-5 items)

Section 3 — Brand Voice Decision Tree

• Branch A (brand_present = true): Extract personality + voice guidelines + color palette + typography from brand-voice.md and visual-identity.md
• Branch B (brand_present = false): Emit ## 3. Brand Voice (default — please customize) header with explicit placeholder + instructions to either edit or run brand interview

See 5-section prompt template + brand branches detail for verbatim section templates.

Prohibited Content in prompt.md

[HARD] The following MUST NOT appear anywhere in prompt.md:

• References to SPEC- identifiers (e.g., SPEC-AUTH-001)
• References to .moai/ paths (e.g., .moai/design/, .moai/project/)
• References to internal skill / agent names (e.g., manager-spec, design-brief, design-handoff-reader)
• References to internal workflow step identifiers
• References to MoAI-specific commands (e.g., /project, /moai plan)
• Internal implementation details (file structures, Go code, database schemas)

The prompt must read as if written by a human product designer with no knowledge of MoAI's internal structure.

Steps 2-5: Supporting Files

See supporting files templates for verbatim references.md, acceptance.md, context.md, and checklist.md templates.

Handoff Exit: AskUserQuestion

After all 5 files are written, the skill MUST surface an AskUserQuestion (with ToolSearch preload) presenting 3 options:

ToolSearch(query: "select:AskUserQuestion")
AskUserQuestion({
  questions: [{
    question: "핸드오프 패키지가 준비되었습니다. 다음 단계를 선택하세요.",
    header: "Design 핸드오프 완료",
    options: [
      {
        label: "Claude Design 세션 시작 (권장)",
        description: "prompt.md를 claude.com Design에 복사해 붙여넣고 디자인 세션을 시작합니다. context.md/references.md는 보조 자료로 함께 엽니다."
      },
      {
        label: "수동 검토",
        description: "핸드오프 파일을 직접 검토하고 필요한 경우 편집합니다. .moai/design/handoff/ 디렉토리를 확인하세요. 준비가 되면 prompt.md를 Claude Design에 붙여넣으세요."
      },
      {
        label: "핸드오프 패키지 재생성",
        description: "prompt.md 또는 다른 파일에 수정이 필요한 경우 어떤 부분을 변경할지 알려주세요. 해당 파일만 재생성합니다."
      }
    ]
  }]
})

For non-Korean conversation_language, translate option labels and descriptions accordingly.

Works Well With

• design-brief: Produces the design brief (Lean Canvas + value propositions) consumed as primary input when the request originates from a brief
• design-system-prep / design-system-library: Provides reference URLs and visual inspiration for the references.md Sources
• design-handoff-reader: Preceding Path A step — summarizes the imported bundle into the inputs this skill consumes
• design-workflow: Downstream consumer of the .moai/design/handoff/ directory after the user completes the external Claude Design session (Path A handler)

Common Rationalizations

Verification

• All 5 files produced: prompt.md, context.md, references.md, acceptance.md, checklist.md
• prompt.md has exactly 5 sections (Goal, References, Brand Voice, Acceptance, Out of Scope)
• prompt.md contains no SPEC- identifiers
• prompt.md contains no .moai/ path references
• prompt.md contains no internal skill/agent names or /design references
• Brand-absent path includes "Brand Voice (default — please customize)" header in prompt.md
• context.md includes note that it is NOT for pasting into Claude Design
• Handoff exit AskUserQuestion called with exactly 3 options
