First run: calibration and your first agent
What happens the first time you open atrium: a three-step calibration that binds a project, connects an agent CLI, and launches your first agent.
atrium has no setup wizard. The first launch drops you into calibration — three steps that get you from a blank install to a working agent, inside the real app rather than a modal in front of it.
Calibration
The Achievements pane opens in calibration mode with three steps, each carrying a single pointer at the thing to do next:
- Open a project — bind a folder on disk. Until you do, atrium renders calibration without inventing a placeholder project for you to look at.
- Connect a tool — open Settings → Tools and install or connect an agent CLI. Wait for it to show Ready. See Launching → binary detection.
- Launch your first agent.
Under each step, a Read the glossary link opens the Glossary, which explains workspaces, projects, wings, rooms, panes, and subtabs in one place. On a computer set to Simplified Chinese, the link is in Chinese and opens the Chinese version. After calibration, the glossary stays one click away under Help → Glossary and in the command palette.
Calibration is uncloseable while active — the pane's ✕, Cmd+W, and the room close paths are all gated, so there is no way to accidentally dismiss the one surface telling you what to do. The lock lifts the instant calibration completes.
If no tool is ready after you visit Settings → Tools, return to calibration and choose Set up later to continue using atrium. The Achievements pane lets you return to calibration when you're ready to connect a tool.
Consent
A consent row during calibration covers telemetry. Analytics are opt-in; declining does not gate any feature.
After calibration
The Achievements pane stays available as a map of everything atrium can do. Most people find several capabilities there they'd otherwise never have looked for.
From here:
- Quickstart — the fastest path to real work.
- Glossary — every atrium term on one page.
- Workspaces and Projects — how atrium organizes things.
- Launching agents — the composer, profiles, and surfaces.
