Claude Cost Optimizer

Claude Cost Optimizer
Cut Claude Code costs with sourced levers: cache reads bill at 5% of input on Opus 5.5 and Sonnet 5.5, Haiku 5.5 costs 1/40 of Opus 5.5 per token (prompts up to 100K tokens), and Batch is 50% off (Anthropic pricing) -- with an installable skill, CLI tools, and 12 deep-dive guides.
No one has published a typical saving for a mixed Claude Code workload, so this repo does not quote one. What is measured: prompt caching cut cost by a factor of 4.8 to 7.2 on a research agent and by 83% to 86% on a small triage agent (Anthropic's cost guide, read 2026-11-01); Anthropic's cost-optimization cookbook stacked model choice, effort and caching on one agent for a 13x lower cost per task ($0.2906 to $0.0223, 10/10 tasks passed both ways); and the cost guide's search over effort and model on tau2-bench retail cut cost per task 61% ($0.142 to $0.055) within a 2-point pass-rate band. See How far can you actually go?, and price your own sessions with /usage or claude-rate.
