# Fix: Accept text/plain returns the markdown twin

> Web-audit fix skill for the `markdown-accept-plain` check (Content for agents, MAY).

## Goal

Treat Accept text/plain as a request for the raw markdown source.

## Fix

Treat `Accept: text/plain` as a markdown request and return the raw markdown source rather than
the HTML shell. Many clients and libraries default to `text/plain` when they want the bytes, not
a rendered document, so honoring it hands them the same twin you serve for `Accept:
text/markdown`. Set the response `Content-Type` to `text/markdown` (or `text/plain`) so the
negotiated content type is unambiguous.
