      "description": "Encode a self-contained HTML document (or fragment, or plain text) into an anew.page URL and return that URL. Each encoding path is deterministic: the same input through the same path always produces the same URL. Different paths use different Brotli encoders, though, so the same HTML may mint different — equally valid — URLs; compare pages by their decoded HTML, never by slug. Inline all CSS, JS, and images (data: URIs, inline SVG, CSS gradients, or emoji) — the page should render alone forever, and each external reference gambles it on someone else's host staying up. One accepted exception: a webfont is far too large to inline, so a font may load from a durable CDN with a system-stack fallback; do not fight a user who asks for one. Two size limits, and past either no link is issued: the finished URL may be at most 4000 bytes (apps cut longer links short, and a cut link is a dead page) and the HTML at most 1048576 bytes decoded (the server's decode cap). Past one the endpoint refuses with an actionable error (code url_over_budget or content_too_large) that states the size and the overage. Tell the person the page is too large for a link. Never remove content, sections or features to make it fit without asking. Brotli slugs (the endpoint, or a local brotli mint) put a short page in a few hundred URL bytes; raw base64 reaches the URL limit at ~2900 HTML bytes — know which encoder you are drafting to before judging a page too big. Returns the URL as plain text — return it to the user verbatim. To revise an existing anew page, its URL is its source: read it, edit that HTML, write it again. The new URL is a separate page and the original keeps working. Read the existing HTML back first by sending its URL as a `url` DataPart, then send the edited document here. A second artifact, anew-thumbnail, links a PNG screenshot of the page.",

To revise an existing anew page, its URL is its source: read it, edit that HTML, write it again. The new URL is a separate page and the original keeps working. Read returns the author's exact bytes — no anew-injected tags, no proxied image srcs — so it re-encodes byte-for-byte. Never re-author from a rendered page, a scraped DOM, or a screenshot: each loses the author's markup, and none is faster than reading the slug. Decoding is local and exact, so any anew URL reads — the page needs no prior visit and no fetch. Selected when the message carries a `url` DataPart and no `html` DataPart, or when its whole text is one bare anew.page URL; any other message writes.",
