+#### 💡 User Experience
+
+The development experience with PromptX is truly different. Our team, using Claude Code combined with PromptX, had one developer complete over eleven thousand lines of high-quality Java code in just three days.
+
+The value of this workflow is fully demonstrated in actual development. PromptX solves many pain points in AI usage, consistently ensuring code style uniformity and quality standards, greatly reducing the learning curve for new team members. Best practices that previously required repeated communication and documentation inheritance can now naturally integrate into every code generation.
