SEEN
agents left you on seen.
One word. Seven doors. Paste a site, watch which ones answer, then take the brief an agent can actually hold. The homepage is not the product.
drop a url. the little one knocks. you get a receipt, then a file.
GET SEEN
The knock is the screenshot. The brief is the thing you host at /brief.md.

what is real
As of September 2026, the doors with actual readers are boring on purpose: robots.txt, a sitemap, AGENTS.md for repos, MCP if you expose tools, an A2A agent card if you expose an agent, and a Content-Signal line if you have a policy. llms.txt is published everywhere and almost never fetched. agents.txt is a contested name, so this page knocks on it and refuses to generate one. ard.json is a cheap catalog if you have something callable. brief.md is ours: not a standards body, a file you can hand an agent today.
Knocks only hit that door list, on public http(s), and stop at private networks. Nothing here buys, sells, or touches a live coin. $EMPTY stays the one that is up. This is the next page.
Stream, when you want it: chat drops a domain. You hit SEEN. You read the ghosts out loud. Then you show the brief.
