AGENTS.md Files Are Not Misleading Your AI Agent

This article examines the controversy around AGENTS.md and CLAUDE.md files used with AI coding agents like Cursor and Claude Code. It references a study showing a 3% performance decrease with these files overall, but a 4% improvement when files are human-written rather than auto-generated via /init commands. The author explains that auto-generated files add noise (like obvious scripts) to the AI's context window, while effective files contain custom conventions, architectural decisions, and business logic quirks that help new developers. The piece provides practical guidance on creating useful agent instruction files for software projects.
