How exactly does Claude not support AGENTS.md?

I can ask Claude to review AGENTS.md and it will read it. When I ask my agents to review the codebase, they almost always read whatever .md files exist.

You're asking the wrong question here. There is:

How exactly does Claude Code* not support AGENTS.md?

How exactly does the Claude suite of Models not support AGENTS.md?

The problem being pointed at in parent linked is referring to the Claude Code Harness not supporting AGENTS.md. Harnesses which do support it (eg codex), append the content to the initial model turn upon the model discovering it at the project root.

* Or Claude Code Tui, Claude Code desktop, Claude Cowork, Claude Desktop, Claude Design, Etc.

(Edit: i wish I could tattoo the distinction on ny forehead. Im vocal about Anthropic engineer-oriented tools being lackluster, and i frequently find myself in conversations where I have to stop a coworker and ask if they're talking about a platform, tool, or model- and which, depending on the answer. I feel like those two things together make me come off somewhat abrasive, but man, we're all engineers here.)

Claude code will only read the other .md files after you take a turn to prompt it, not when the session starts. So if I run `/clear` it will retain the CLAUDE.md context but not AGENTS.md.
