Write down how you work, what you know, and how to reach you — once, in plain markdown. People read it as a profile. Agents fetch the same file before they email you, book you, or write on your behalf.
Start from a short template. Headings, lists, links — nothing you need a manual for.
Drafts stay private. Publishing lists you in the directory under a handle that never changes.
Every profile is served raw at /handle.md. Paste the link into a prompt, a system file, or an email signature.
