Anthropic closes feature request to support AGENTS.md standard in Claude Code
A GitHub feature request asking Anthropic's Claude Code to support the cross-tool AGENTS.md convention was closed, leaving Claude Code tied to its own CLAUDE.md format.
AGENTS.md is emerging as a shared Markdown convention that multiple coding agents, including Codex, Amp, and Cursor, can use to understand a codebase, while CLAUDE.md remains specific to Claude Code. Engineers working across multiple AI coding tools must maintain separate instruction files, and teams with non-Claude Code users lose interoperability. The closure signals Anthropic is not currently adopting the cross-agent standard.

A feature request on the claude-code GitHub repository asked for support of AGENTS.md, a unified Markdown file that coding agents use to understand a codebase.
The request noted that Codex, Amp, Cursor, and others are standardizing around AGENTS.md, while CLAUDE.md is too specific to Claude Code and hinders collaboration with developers using other tools.
The issue was closed, indicating Anthropic declined to implement the requested support at this time.
