The post explains how to build a well-structured AGENTS.md or CLAUDE.md file for a real project, introduces a script to detect context drift (stale paths and outdated timestamps), and outlines best practices like version-controlling the file, keeping it scannable, including self-verification commands, and splitting context files in monorepos. The core argument is that agent output quality is a direct function of context quality, and treating these files as living infrastructure rather than one-time setup is what separates agents you babysit from ones you can trust with real tasks. ## Full article daily.dev links to this article rather than hosting it.
