So, a supposedly trillion dollar worth, about to IPO company thinks their moat is a specifically named Markdown file.

Making your tool less compatible with the rest of the ecosystem at large not only makes it harder to move to your tool, but also harder to move away from your tool. Given these AI labs basically have no moat, seems they're trying to hold on to every little piece they can do make it harder to move away, even if it's a really tiny and marginal feature, like specifically titled file on disk... Kind of embarrassing overall, but I guess they make so much money no people there have any shame left to feel.

That's true but this is really not something that's a barrier to switching, just an annoyance for users. All it takes is a rename/symlink/reference whatever from the user's perspective. If it required a lot of rearchitecting on Anthropic's side or it was a _lot_ harder for users to adapt to I'd understand them standing their ground on this issue. But neither of those are true, it's just pettiness.

Depends on how you use these harnesses, I don't interact with any of them directly for example, but have my own harness around them, mostly so I can collect all the different ones under one "roof". With that, comes certain expectations of where things live. Anything that has "CC uses file path X" for example would require refactoring/changes, compared to other agents. Contrived example, but sometimes it's more than just "mv AGENTS.md CLAUDE.md".

It's not a moat, or much of a barrier because you can literally just rename it, but it is 'good' marketing/branding. People talking about CLAUDE.md is much better for Anthropic than people talking about AGENTS.md.

I think it’s more branding than moat. Free advertising if every vibe coded repo on GitHub has a CLAUDE.md at the root.

And its probably also to make people think there’s something special about Claude.

just the filename. The contents of the file are unstructured, besides being markdown

But the semantic meaning can be agent-specific. For instance, my Claude.md files have things like “never present multiple questions in walls of text, use `AskUserQuestion` with clear tradeoffs described”

it is still just an unstructured file

Why do people continue to use the word “moat” only in context of AI companies?

I don’t think that’s true? I’ve been here quite a while now and it goes back a long long time in the startup world
