+## Git Commit Message Rules
+
+**IMPORTANT**: Commit messages must be user-friendly and business-focused:
+- **Main message** should describe what the change accomplishes for users/business
+- **Secondary lines** can include technical implementation details
+- Focus on the problem being solved rather than technical jargon in the main message
+- Example:
+  - Good: "Fix product import when image uploads fail"
+  - Bad: "Add Promise.allSettled and timeout handling to parseProduct"
+- Keep main message concise and clear about the user impact
+- Technical details belong in the commit body, not the subject line
+
