A software developer using Claude Code found that 95% of their AI coding quota was consumed in just two days, primarily due to the model re-reading extensive conversation histories rather than generating new code. The developer's logs revealed that 99.9% of processed tokens were for context re-reads, with cache reads accounting for 97.6% of all tokens. This high cost is attributed to large context windows (over 200k tokens) and the use of subagents, which multiply requests by re-reading context for each step. To manage this, the developer plans to limit session context size, reduce parallel subagents, and use smaller models for routine tasks. AI
