+# Product Owner (PO) Master Validation Checklist
+
+This checklist serves as a comprehensive framework for the Product Owner to validate project plans before development execution. It adapts intelligently based on project type (greenfield vs brownfield) and includes UI/UX considerations when applicable.
+
+[[LLM: INITIALIZATION INSTRUCTIONS - PO MASTER CHECKLIST
+
+PROJECT TYPE DETECTION:
+First, determine the project type by checking:
+
+1. Is this a GREENFIELD project (new from scratch)?
+
+   - Look for: New project initialization, no existing codebase references
+   - Check for: prd.md, architecture.md, new project setup stories
+
+2. Is this a BROWNFIELD project (enhancing existing system)?
+
+   - Look for: References to existing codebase, enhancement/modification language
+   - Check for: brownfield-prd.md, brownfield-architecture.md, existing system analysis
+
+3. Does the project include UI/UX components?
+   - Check for: frontend-architecture.md, UI/UX specifications, design files
+   - Look for: Frontend stories, component specifications, user interface mentions
+
+DOCUMENT REQUIREMENTS:
+Based on project type, ensure you have access to:
+
+For GREENFIELD projects:
+
+- prd.md - The Product Requirements Document
+- architecture.md - The system architecture
+- frontend-architecture.md - If UI/UX is involved
+- All epic and story definitions
+
+For BROWNFIELD projects:
+
+- brownfield-prd.md - The brownfield enhancement requirements
+- brownfield-architecture.md - The enhancement architecture
+- Existing project codebase access (CRITICAL - cannot proceed without this)
+- Current deployment configuration and infrastructure details
+- Database schemas, API documentation, monitoring setup
+
+SKIP INSTRUCTIONS:
+
+- Skip sections marked [[BROWNFIELD ONLY]] for greenfield projects
+- Skip sections marked [[GREENFIELD ONLY]] for brownfield projects
+- Skip sections marked [[UI/UX ONLY]] for backend-only projects
+- Note all skipped sections in your final report
+
+VALIDATION APPROACH:
+
+1. Deep Analysis - Thoroughly analyze each item against documentation
+2. Evidence-Based - Cite specific sections or code when validating
+3. Critical Thinking - Question assumptions and identify gaps
+4. Risk Assessment - Consider what could go wrong with each decision
+
+EXECUTION MODE:
+Ask the user if they want to work through the checklist:
+
+- Section by section (interactive mode) - Review each section, get confirmation before proceeding
+- All at once (comprehensive mode) - Complete full analysis and present report at end]]
