The AGENTS.md file is an open standard hosted by the Linux Foundation, designed to consolidate project instructions for AI coding agents into a single Markdown file. This standard aims to prevent the proliferation of duplicate and outdated instruction files, such as CLAUDE.md or Copilot-specific files, that often exist across different AI tools used on the same project. While AGENTS.md is natively supported by many agents including Claude Code, Cursor, and Copilot, some tools still maintain their own specific file formats or offer unique features like per-file scoping, leading to continued file sprawl. The recommended approach is to use AGENTS.md as the primary source and create minimal bridge files for agents that require their own format, importing the AGENTS.md content to maintain consistency.

IMPACT Standardizes project instructions for AI coding agents, reducing duplication and improving consistency across tools.
RANK_REASON The article describes a new standard for AI coding agents and how to use it with existing tools, rather than a release from a frontier lab.
