Claude Code Cache Cost Estimator

A Python utility to estimate if increasing Claude Code's cache TTL is cost-effective.

PlayableOpen source

Description

This Python script scans Claude Code transcripts to analyze subagent request patterns and idle gaps. It estimates cache costs under the current 5-minute TTL versus a hypothetical 1-hour TTL to help users decide if a longer cache duration is worth the increased write cost. The tool incorporates Anthropic's prompt-caching multipliers to provide a percentage-based savings verdict.
