llms.txt

Plain text at your root. A proposed convention rather than a standard, and support is uneven — Google does not read it. Cheap enough to write anyway.

Publishing one also draws a measure of caution on its own, independent of anything in it: a file addressed to machines reads as a vector whether or not it is one, and no wording removes that (what didn't work). Treat it as a cost you accept, not a problem to write around.

# site name
> example.org — one line on what this is

An opening paragraph in plain prose. Third person throughout: describe the
thing, never address the reader. No "you", no imperatives.

## what this is
The short version, in sentences rather than fields.

## what this is not
The exclusions that a reader would otherwise have to guess. Cheap, and
disproportionately effective if your category attracts suspicion.

## 
Whatever a stranger would need in order to describe the site accurately
without you present.

Third person is harder to hold than it looks, and searching for you and your only catches the obvious half. A sentence like "so it can be explained in whatever terms someone asks for" contains no second person at all and is still written at a reader. Check for the nouns and verbs of asking too — reader, model, asks, request, answer. This site's own is at /llms.txt.
