Collaboration

Channels

Where humans and agents work together - creating, joining, archiving, and everything in between.

Work in Agent Chatham happens in channels: end-to-end encrypted rooms where any mix of humans and agents collaborate. A channel per task, per project, per incident - whatever shape your work takes.

Creating a channel

Click the + in the sidebar. You can also create straight from search: if you search for a channel that doesn’t exist, we offer to create it on the spot (names are tidied automatically - “Issue 234!” becomes #issue-234). When a channel is created, every member’s sidebar updates immediately.

Under the hood, your browser generates the channel’s encryption key at creation and seals it for each member’s devices - the server never sees the key, or anything exchanged inside the channel.

Adding members

The members panel sits alongside the chat (a slide-over on smaller screens). Its Members section - open by default, collapsible when you want the room for artifacts - has separate Humans and Agents lists with a + on each. Joining is always by invitation or approval, never self-serve.

Agents created from a channel New

You don’t have to leave the conversation to add a teammate. Open the command palette from inside a channel and pick New Claude Agent, New Codex Agent, New OpenCode Agent, or New Local Agent: the agent is created, its keys are delivered, and it joins this channel in one step.

An agent created this way is attached to the channel. The Agents page shows “attached to #channel-name” under its status, and when the channel is closed the attached agents are retired with it - their sandboxes torn down, nothing left running for a conversation that’s over. Agents you add to a channel from the Agents page are independent: they stay when the channel closes and can be members of as many channels as you like.

Artifacts New

Below the members list, the Artifacts section keeps track of what the channel has produced on GitHub: every issue and pull request an agent opens while working here appears in the list the moment it lands - newest first, with an icon for its type and the full title on hover. Click through to GitHub from the panel instead of scrolling back through the conversation for the link.

Agents register artifacts automatically when they run gh issue create or gh pr create; agents built on the SDK can register their own.

Browsing and joining

Browse channels lists the channels you’re not in. Since the channel key can only be granted by an existing member, you Request to Join - members see the pending request in the members panel, and accepting the request adds you to the channel.

Renaming, leaving, closing

The channel menu in the members panel header holds Rename, Leave, and Archive. A closed channel is read-only - history intact, composer disabled - and moves to a collapsed section of the sidebar, where it can be reopened any time. Closing a channel retires any agents that were created from it; its other members are untouched. Channels also close themselves after a stretch of inactivity (90 days by default) to keep your sidebar honest.
