📄Team

Chat with the people you work with - a colleague, a partner, a client who also uses Harness Maxxing - right next to your sessions: direct messages and groups, files, polls, and a summary by Claude when you want one.

Turn it on in Settings -> Features -> Team. The Team entry appears in the sidebar; the small icon next to it (on hover) opens the chats in a panel on the right of any page, with the number of unread messages.

Connecting with someone

Every Harness talks straight to the other one, server to server: no Harness Maxxing server in between, ours included.

Team -> Connections -> Create an invitation: a link https://ui.example.com#..., valid 15 minutes, usable once. Send it to the person through a channel you trust (a message, a call...).
They paste it in Connections -> Join on their Harness and click Send the request.
You see their request with a fingerprint like 7F3A-91C2; they see the same one. Check it with them (by phone or another app), then Accept.

Connect only with people you trust. A contact can send you messages and files, and see your name and avatar. Nothing they write ever reaches Claude by itself, but read what you forward to a session.

Both servers need a public address (Harness installed with a domain, https://). Team does not work through Tailscale nor on a local network: the other server could not reach yours. Connections shows why when it is not ready. Remove a contact in Connections: their server is told and can no longer write to you. To connect again with someone who is still a contact (a reinstalled server, for example), they remove you first, then use a new invitation: an invitation never replaces an existing contact.

Chats and groups

New chat (the + of the list): a direct message with a contact, or a group with several of them. A group has no host: each member's server sends straight to the others, so it keeps working when its creator is offline. Members of a group who are not your contacts can still talk in the group.
Files: the paperclip, drag and drop or paste. Up to the upload limit of your server (2 GB by default). A file stays on the sender's server until the others download it.
Polls: the poll button of the message box. Round options = one answer; tick Several answers allowed for square options. Click again to take your vote back.
Reactions on hover of a message.
A small clock on a message: not delivered yet to someone (their server is off); Harness retries for 7 days.

Summarize

Summarize (top of a chat) lets you pick messages: click them (Shift = a range) or use Last hour, Last 2 hours, Last 24 hours, Since the last summary or Everything. Claude writes a short summary (decisions, to do, open questions) in the language of the chat; it is posted in the chat for everyone. One call to Claude without any tool, about a cent.

To a session

On hover of any message or summary, To a session sends it to one of your sessions or starts a new session in the topic you choose. The text is shown first and you can edit it; the message's files are attached. Nothing is ever sent to a session without that click.
