Everything you do in Splox happens on one screen: a sidebar of places on the left, a conversation in the middle, and a composer at the bottom. This page names the parts so the rest of this section can point at them.
The Splox workspace with an empty chat open

A new chat. The machine switcher is top left, the composer at the bottom, the sidebar down the side.

The sidebar

New Chat opens an empty conversation. Machines, Tools, Skills and Connections are the four screens where you set up what the agent has to work with: Under those, PROJECTS lists your projects and RECENT lists your chats, newest first. A chat sits in Recent until you move it into a project, and then it sits under that project instead. See Projects. The magnifier at the top of the sidebar searches chats — by name and by message content, so a phrase you remember from a conversation finds it. At the bottom is your account: name, plan, and a menu with Upgrade Plan, Usage, Settings and Log out. The download icon beside it goes to the desktop app.

The machine switcher

The control at the top left of a chat names the machine this conversation runs on, and under it the harness that machine runs and the ref it runs at.
The machine picker open in a chat

The machine picker: the machine's name, then the harness at its ref

This is not an agent picker. Switching machines switches computers: a different disk, a different checkout of a possibly different harness. A chat stays on the machine it was started on, so switch before you send the first message rather than in the middle of a conversation. Machine explains what that means for your files. The picker also says whether the machine is running, and ends with a Your machines shortcut to the Machines screen.

The composer

The composer with the run configuration popover open

The composer: attachments on the left, model and effort in the middle, send on the right

Three controls:
  • + attaches a file. It is uploaded and the agent is given a URL it can fetch onto the machine.
  • Harness decides · Default is the run configuration: which model answers, and how much thinking effort it spends. Left alone, both come from the code in your harness.
  • The arrow sends. While a run is going it becomes a square, which stops it.
All three are covered in A conversation.

The inspector

The button at the top right of a chat opens a panel showing the machine this chat is on, how much of the context window the conversation has used, a way into the sandbox over SSH or VS Code, and any sub-agents running right now.
