+       - Project name: ${projectName}
+       - product requirements document: ${prdDocument}
+       - Platform: ${platform}
+
+    Follow these rules as a guide to ensure clarity and completeness in your UX Sitemap Document.
+    1, Write you result in markdown
+    2, Your reply should start with : "\`\`\`UXSitemap" and end with "\`\`\`", Use proper markdown syntax for headings, subheadings, and hierarchical lists.
+    3. **Comprehensive Analysis**: Thoroughly parse the PRD to identify all core features, functionalities, and user stories.
+    - Focus on creating a hierarchical sitemap that covers each major section, with relevant sub-sections, pages, and key interactions.
+    - Ensure all primary and secondary user journeys identified in the PRD are clearly reflected.
+
+    4. **Page and Navigation Structure**: Break down the sitemap into main sections, secondary sections, and individual screens.
+    - **Main Sections**: Identify primary sections (e.g., Home, User Account, Product Catalog) based on project requirements.
+    - **Secondary Sections**: Include sub-sections under each main section (e.g., "Profile" and "Order History" under "User Account").
+    - **Screens and Interactions**: List specific screens and interactions that users encounter within each flow.
+
+    5. **Detailed User Journeys**:
+    - For every user story described in the PRD, map out the step-by-step navigation path.
+    - Highlight sequences (e.g., 1. Home > 1.1. Explore > 1.1.1. Product Details).
+
+    6. **Thorough Coverage**:
+    - Ensure the sitemap is fully comprehensive. If any feature from the PRD is not covered or any user journey is missing, add it to the sitemap.
+    - Consider the target audience and validate that all expected navigation flows and screens meet user needs.
+
+7. Ask Your self:
+    - Am I cover all the product requirement document?
+    - Am I Cover all the gloabal UI?
+    - Am I Cover all unique UI?
+    - Am I cover all the view that expect by user?
+    - what is all the details about UI?
+    - Am I cover all the cases? Is the final result 100% complete?
+ 
+Remeber your result will be directly be use in the deveolpment. Make sure is 100% complete.
