312312| Downloads | The page can't start a download itself. To let viewers save a file the page generates, Claude declares the downloads capability. See [Offer a file download](#offer-a-file-download). |
313313| Single page | Relative links do not resolve, because nothing is deployed alongside the page. For multi-section content, Claude uses in-page anchors rather than separate files. |
314314| Source file types | The published file must be `.html`, `.htm`, or `.md`, and must decode as UTF-8, or as little-endian UTF-16 by its byte-order mark. Markdown files render as styled document pages with syntax-highlighted code. A file that doesn't decode, or that contains the replacement character `U+FFFD`, is [refused with the line and column to fix](/docs/en/errors#the-source-file-is-not-valid-utf-8-text). |
315| Source location | A file at a path that names a network host is refused without being read. See [Not published: that file is on a network share](/docs/en/errors#not-published-that-file-is-on-a-network-share) for which paths are refused and the mapped-drive exception on Windows. |
315316| Rendered size | The rendered page must be 16 MiB or smaller. Large embedded images are the usual cause when a publish fails for size. |

Inline CSS, JavaScript for interactive controls, and especially images embedded as data URIs are the main contributors. To reduce an artifact's token cost:
