Claude-thermos is a Python library that keeps the prompt cache warm for Claude Code sessions, reducing the cost of rebuilding the cache when the main agent is idle and a subagent is running, by automatically sending warm requests to the Claude API. These warm requests are cheap cache reads that refresh the full cached prefix, preventing expensive rewrites. The library logs event data and provides a rollup summary of the warming decisions and savings. AI summary

Using AI can create an illusion of flow in coding, making it easier to write more code and deliver features faster, but this can also mask a "depth problem" where the AI's output may not be a direct translation of the user's intent, making it difficult to evaluate the quality of the code. In contrast, traditional text editors like Vim provide a direct and transparent relationship between the user's intent and the output, allowing for better evaluation of the code's quality. This disparity can lead to an "empathy gap" where non-engineers may underestimate the complexity and effort required to develop high-quality software. AI summary
