Analysis

This article offers a fascinating look into the mechanics of 'harness' software, brilliantly explaining how modern AI agents like Cursor and Claude Desktop actually function. By examining the raw inputs and outputs passed to the Large Language Model (LLM), it demystifies the complex orchestration happening behind the scenes. It's an incredibly exciting read for anyone looking to understand how tools like 検索拡張生成 (RAG) and multimodal features are expanding the capabilities of AI.
