Cost Track is an essential utility for the Ruflo meta-harness that monitors Anthropic Claude API usage in real-time. By parsing active session logs, it calculates precise USD costs based on current pricing models—including cache-write and cache-read tokens—and persists this data to a dedicated memory namespace. It acts as the primary data provider for cost reporting and optimization workflows, ensuring developers have a transparent, granular view of their AI development expenses across different models like Opus, Sonnet, and Haiku.
