For AI agents: a documentation index is available at the root level at /llms.txt. Append /llms.txt to any URL for a page-level index, or .md for the markdown version of any page.
Email files (.msg, .eml): an email is indexed as a text document for the message and one document per attachment, each parsed as its own type. email_attachment and email_reply_to relations link the parts and the thread in both directions, and every part carries email_* metadata for filtering by thread, sender, subject, or date. See Supported File Types.
