Devs say avoiding cache misses could boost Claude Code/Codex effective usage limits 10-20%

A developer argues that preventing cache misses is probably the single biggest thing you can do to get the most out of your usage quota. The quoted post goes further, calling on OpenAI and Anthropic to build this into Claude Code and Codex, claiming it would instantly raise effective usage limits by 10-20%.
The underlying logic: prompt cache hits affect not just cost but how much work fits in the same quota, and workflow design (stable prefixes, minimal context churn) determines hit rate.
