🧠 Intelligent Features Deep Dive

📊 Session Analytics & Statistics

The CLI now tracks comprehensive real-time metrics:

• Performance Metrics: API call timing, success/failure rates, retry counts
• Content Analysis: Message counts, token estimation, context optimization savings
• Error Tracking: 418/429 error monitoring, VQD refresh rates, header refresh frequency
• Usage Patterns: Command usage statistics, model changes, file/URL processing
• Session Duration: Total time spent in the session, average response times

Commands:

• /stats - View current session analytics anytime
• Automatic display on /exit with detailed session summary

🎯 Smart Context Optimization

Automatically manages conversation context for optimal performance:

• Intelligent Compression: Compresses old context when approaching token limits
• Importance Scoring: Preserves critical information while removing redundant content
