Anthropic will ship Claude Code support for AGENTS.md repository instructions that interoperably honors the same repository guidance used by other compatible coding agents.

What is this?
AGENTS.md is an open Markdown format for storing repository-level context and instructions for coding agents, with its site claiming adoption by more than 60,000 open-source projects. A GitHub issue in Anthropic’s Claude Code repository requested native support so Claude Code could share guidance with Codex, Amp, Cursor, and other agents instead of relying on the Claude-specific CLAUDE.md. The supplied snippets do not establish that Anthropic implemented or committed to this support: one guide says Claude Code still does not read AGENTS.md by default and recommends importing it from CLAUDE.md, while the primary-source snippet shows only the feature request, not its claimed closure as completed.
Why it matters to Scott
If confirmed, Anthropic’s native AGENTS.md support would bring a consequential coding-agent vendor directly toward Scott’s existing Markdown OS and portable soft-weights position, while removing vendor-specific configuration duplication across Claude Code and Codex workflows he actively uses. The supplied evidence does not yet establish implementation, so the immediate opportunity is to verify behavior and document precedence, scoping, and reliability rather than treat the feature as shipped.

The first-party closure resolves the request with an existing CLAUDE.md import or symlink pattern, not native AGENTS.md discovery. That preserves a usable interoperability workaround but does not substantiate the case’s shipping hypothesis.
