Tool Cost Tracking

Domain: Tools & Function Calling

🎯 Motivation

Some tools cost money per use (API calls, cloud services). Tracking cost per tool call helps manage budgets.

📋 Concrete Example

Cost log: search_web: 0.05. Image generation: 0.10. Total: 0.20, 5 more searches are OK. Cost tracking prevents overspending.

🔗 Analogy

Tracking spending on a trip - taxi: 50, tickets: 100. If budget is 50 left. Tool cost tracking budgets agent spending.
