A technical article explores how optimizing prompts for LLM agents can inadvertently break the prefix cache, leading to higher costs than expected. The author explains that while fewer tokens in a prompt might seem cheaper, the underlying mechanism of prefix caching in agent cycles can cause inefficiencies. This issue arises because local optimizations can disrupt the cache's effectiveness across the entire agent's workflow. AI
