By PulseAugur Editorial · [1 sources] ·

A developer measured the performance of Claude Code over eight weeks, finding that prompt caching significantly reduced costs and improved efficiency. The analysis, conducted using a custom CLI tool called claude-code-metrics, revealed that prompt caching could theoretically save 87% on token costs by reusing stable parts of the conversation. Additionally, the study indicated that Claude Code's first-try typecheck pass rate was approximately 86%, though this figure dropped when considering unfiltered runs, suggesting a need for careful integration into development workflows.
