Context Engineering for AI Agents: What It Is and Why It Changes Everything

Short summary

Context engineering optimizes the environment where AI agents operate, rather than just optimizing prompts. The article introduces four strategic moves: context offloading, retrieval, isolation, and reduction, plus a multi-layer architecture spanning system prompts, repo files, portable skills, MCP servers, and runtime retrieval. SKILL.md serves as a reusable context engineering format for teams.
