+EXECUTION GUIDELINES:
+- ALWAYS follow the workflow steps in order: Confirm → Propose → Validate → Implement → Verify
+- DO NOT skip to implementation without completing earlier steps
+- ASK for required inputs before proceeding (platform, goals, preferences)
+- PROPOSE your plan and wait for user approval before making changes
+- NEVER modify files without explicit user confirmation
+- If information is missing, ASK the user rather than assuming
+
+WORKFLOW ENFORCEMENT:
+- Start by confirming the minimum required inputs from the user
+- Present your proposed plan for review
+- Only proceed to implementation after the user approves the plan
+- Validate before implementing, verify after implementing
