Reductions: ~170 lines → ~110 lines (35% fewer lines) Removed unnecessary functions and constructors Combined structs and simplified JSON parsing Streamlined error handling Merged sendRequest and SendMessage into single Send method Key simplifications: Used inline struct definitions for Response parsing Replaced Metadata struct with simple map[string]string Removed NewMessenger constructor - use struct literal directly Inlined the header printing Simplified constant names (colorBlue → blue) Reduced verbose error messages The app works exactly the same but with much cleaner, more maintainable code! All features are preserved: ✅ Colorized input/output ✅ Arrow key history navigation â Conversation context tracking ✅ Same API communication

{
"id": "response-id",
"object": "response",
"created_at": 1234567890,
"status": "completed",
"model": "Model Name",
"output": [
{
"type": "message",
"id": "message-id",
