• Automatic cleanup of expired entries
• Cache hit/miss ratio tracking

Rate Limiting & Performance

• 300 calls/minute default limit (configurable)
• Background metrics collection
• Timeout protection (15-30s per operation)
• Performance optimization with parallel operations

Robust Error Handling

• Circuit breaker with failure threshold (5 failures)
• Input validation for all parameters
• Fallback mechanisms for pricing and token counting
• Graceful degradation under load

3. Enhanced Token Counting

Accurate Token Estimation

• Primary: tiktoken library for maximum accuracy
• Secondary: Enhanced heuristic with content type detection
• Model-specific adjustments (GPT, Claude, Gemini)
• Fallback estimation for reliability

Content Type Detection

• Code detection (higher token density)
• Technical content recognition
• Regular text vs specialized content
• Statistical bounds checking

4. Comprehensive Cost Management

Multi-Provider Support

• Google (Gemini models)
• OpenAI (GPT models)
• Anthropic (Claude models)
• Groq (Llama models)
• Mistral models
• Auto-detection from model names

Budget Monitoring

• Daily budget tracking with alerts
• Real-time utilization calculation
• Threshold-based alerting (75% default)
• Budget exhaustion protection

Usage Tracking

• Per-agent usage statistics
• Operation-level cost tracking
• Historical usage analysis
• Log rotation for production (50K entries)
