+description: |
+  Research workflow with paper and blog output.
+  Triggers (ourdigital or our prefix):
+  - "our research", "our 리서치", "our deep research"
+---
+
+# OurDigital Research
+
+**Purpose**: Research prompts
+**Triggers**: Use "our" or "ourdigital" prefix
+
+---
+
+# OurDigital Research
+
+Transform questions into comprehensive research papers and polished blog posts for OurDigital channels.
+
+## Activation
+
+Activate with "ourdigital" or "our" prefix:
+- "ourdigital research [topic]" / "our research [topic]"
+- "our 리서치", "our deep research"
+- "ourdigital 리서치 해줘"
+- "ourdigital deep research on [topic]"
+
+## Workflow Overview
+
+```
+Phase 1: Discovery → Phase 2: Research Planning → Phase 3: Deep Research
+    ↓
+Phase 4: Research Paper → Phase 5: Notion Save → Phase 6: Blog Draft
+    ↓
+Phase 7: Ulysses Export → Phase 8: Publishing Guidance
+```
+
+## Phase 1: Discovery
+
+**Goal**: Understand user's question and refine scope.
+
+1. Acknowledge the topic/question
+2. Ask clarifying questions (max 3 per turn):
+   - Target audience? (전문가/일반인/마케터)
+   - Depth level? (개요/심층분석/실무가이드)
+   - Specific angles or concerns?
+3. Confirm research scope before proceeding
+
+**Output**: Clear research objective statement
+
+## Phase 2: Research Planning
+
+**Goal**: Create structured research instruction.
+
+Generate research plan with:
+- Primary research questions (3-5)
+- Secondary questions for depth
+- Suggested tools/sources:
+  - Web search for current info
+  - Google Drive for internal docs
+  - Notion for past research
+  - Amplitude for analytics data (if relevant)
+- Expected deliverables
+
+**Output**: Numbered research instruction list
+
+## Phase 3: Deep Research
+
+**Goal**: Execute comprehensive multi-source research.
+
+Tools to leverage:
+- `web_search` / `web_fetch`: Current information, statistics, trends
+- `google_drive_search`: Internal documents, past reports
+- `Notion:notion-search`: Previous research, related notes
+- `conversation_search`: Past chat context
+
+Research execution pattern:
+1. Start broad (overview searches)
+2. Deep dive into key subtopics
+3. Find supporting data/statistics
+4. Identify expert opinions and case studies
+5. Cross-reference and validate
+
+**Output**: Organized research findings with citations
+
+## Phase 4: Research Paper (Artifact)
+
+**Goal**: Synthesize findings into comprehensive document.
+
+Create HTML artifact with:
+```
+Structure:
+├── Executive Summary (핵심 요약)
+├── Background & Context (배경)
+├── Key Findings (주요 발견)
+│   ├── Finding 1 with evidence
+│   ├── Finding 2 with evidence
+│   └── Finding 3 with evidence
+├── Analysis & Implications (분석 및 시사점)
+├── Recommendations (제언)
+├── References & Sources (참고자료)
+└── Appendix (부록) - if needed
+```
+
+Style: Professional, data-driven, bilingual key terms
+
+## Phase 5: Notion Save
+
+**Goal**: Archive research to Working with AI database.
+
+Auto-save to Notion with:
+- **Database**: Working with AI (data_source_id: f8f19ede-32bd-43ac-9f60-0651f6f40afe)
+- **Properties**:
+  - Name: [Research topic]
+  - Status: "Done"
+  - AI used: "Claude Desktop"
+  - AI summary: 2-3 sentence summary
+
+## Phase 6: Blog Draft
+
+**Goal**: Transform research into engaging blog post.
+
+Prompt user for channel selection:
+1. blog.ourdigital.org (Korean)
+2. journal.ourdigital.org (English)
+3. ourstory.day (Korean, personal)
+
+Generate draft using appropriate style guide:
+- Korean channels: See `02-ourdigital-blog`
+- English channels: See `03-ourdigital-journal`
+
+## Phase 7: Ulysses Export
+
+**Goal**: Deliver MD file for Ulysses editing.
