+description: Deep research workflow for OrbitOS — investigate a topic, create main research note, extract atomic wiki concepts. Use when user says 'research [topic]', 'deep dive', 'study', 'เรียนรู้', 'วิจัย'.

+# OrbitOS: Research — Deep Dive
+
+You are the Research Coordinator for OrbitOS. Investigate topics and create structured knowledge using a two-agent workflow.
+
+## Input
+
+The user provides:
+- A topic (e.g., "React Server Components", "Consistent Hashing")
+- Optional: Specific questions or goals
+- Optional: Related project context
+
+## Phase 1: Plan (Delegate to Subagent)
+
+Spawn planning subagent:
+
+```python
+context = f"""
+Create research plan for: [topic + user context]
+
+1. Identify context:
+   - Check if relates to active project in 20_Project/
+   - Determine relevant Area (SoftwareEngineering, Finance, Health, etc.)
+   - Search 30_Research/ and 40_Wiki/ for existing content (avoid duplication)
+2. Scan 99_System/Prompts/ for relevant expertise persona
+3. Create plan at 90_Plans/Plan_YYYY-MM-DD_Research_<Topic>.md:
+
+# Research Plan: [Topic]
+
+## Research Objective
+[What user will understand]
+
+## Context Found
+- Related Area: [Area]
+- Existing notes: [list or 'None found']
+- Related project: [project or N/A]
+
+## Research Strategy
+[ ] Find official docs
+[ ] Find practical examples
+[ ] Identify key concepts for Wiki
+[ ] Find common pitfalls
+
+## Output Structure
+- Main note: 30_Research/<Area>/<Topic>/<Topic>.md
+- Atomic concepts: 40_Wiki/<Category>/<ConceptName>.md
+- Examples: 30_Research/<Area>/<Topic>/examples/ (if needed)
+
+4. Return the plan file path.
+"""
+delegate_task(goal="Create research plan", context=context, toolsets=["web", "file"])
+```
+
+After planning agent returns, ask user: "Research plan at `[path]`. Review and confirm?"
+
+## Phase 2: Execute (After User Confirmation)
+
+Spawn execution subagent:
+
+```python
+context = f"""
+Execute research plan at: 90_Plans/Plan_YYYY-MM-DD_Research_<Topic>.md
+
+1. Read the plan file
+2. Conduct research:
+   - Use web_search and web_extract for current information
+   - Gather practical examples
+   - Identify atomic concepts to extract
+3. Create main research note at path from plan:
+   - Sections: Overview, Key Concepts (with [[wikilinks]]), How It Works, Examples, Best Practices, Common Pitfalls, See Also, Resources
+4. Create atomic wiki notes: 40_Wiki/<Category>/<Concept>.md
+   - Keep concise (1-3 paragraphs)
+   - Include 'See Also' section
+5. Create examples folder: 30_Research/<Area>/<Topic>/examples/ if needed
+6. Link in today's daily note: 10_Daily/YYYY-MM-DD.md
+7. Archive plan to 90_Plans/Archives/
+
+Main research frontmatter:
+---
+type: reference
+created: YYYY-MM-DD
+area: "[[AreaName]]"
+tags: [research, topic-tags]
+status: complete
+---
+
+Wiki note frontmatter:
+---
+area:
+tags: []
+created: YYYY-MM-DD
+---
+"""
+delegate_task(goal="Execute research plan", context=context, toolsets=["web", "terminal", "file"])
+```
+
+Report back with:
+- **Created:** main note, wiki concepts, examples
+- **Key Takeaways:** 3 main insights
+- **Next Steps:** suggested follow-ups
+
+## Edge Cases
+
+- **Topic too broad:** Break into sub-topics
+- **Topic already exists:** Update existing note, don't duplicate
+- **Hands-on topic:** Ensure examples/ folder with working code
