+# Create PR Description
+
+Create a concise PR description for the current branch's PR focusing on architecture over implementation details.
+
+Consolidate related details under fewer sections and emphasize high-level decisions rather than exhaustive details.
+
+Reference any design documents or branch commits for deeper context instead of including all details in the description.
+
+**Output the proposed PR description in markdown and use the following structure:**
+
+```markdown
+# Overview
+
+[Brief summary of the PR's purpose and scope.]
+
+## Key Changes
+
+- [High-level change 1]
+  - [Optional: Brief detail or sub-point about change 1.]
+
+  [Optional additional context or rationale for change 1.]
+
+- [High-level change 2]
+  - [Optional: Brief detail or sub-point about change 2.]
+
+  [Optional additional context or rationale for change 2.]
+
+## Design Decisions
+
+[Explanation of major design decisions made in the PR, focusing on architecture and rationale rather than implementation specifics.]
+
+## Overall Flow
+
+[Include any relevant architecture diagrams or flowcharts that illustrate the changes made. Written in mermaid syntax; use sequence diagram unless another format is more appropriate.]
+```
+
+- Ask me for feedback on the generated description before finalizing it.
+- Once approved, ask me if I'd like to copy in markdown format to my clipboard. Copy to clipboard only if I confirm.
