Agent Session Manager

Keeps Claude Code, Codex, Cursor, and OpenCode managed in a window optimized for multi-agent workflows.

Features

Tabs represent a working directory. Each tab has a name and a root directory. Switch between them with ⌘1–⌘9.

Panes are terminal sessions inside a tab. Creating an agent pane launches the selected tool (Claude Code, Codex, Cursor, or OpenCode) in an isolated git worktree. You can also open a plain shell in an existing pane. Panes auto-arrange in a grid (1×1 → 2×1 → 2×2 → 3×2 → 3×3) as you add more.

Status line — each pane can show a live, configurable status bar at the bottom with app-owned and tool-specific information such as the model, worktree name, cost, context usage, and more. Available items vary by tool, and custom fields are supported in Settings → Status Line.

CLI options — each supported tool has its own catalog of configurable CLI options in Settings → Harnesses. Enabled options appear as toggles and text fields in the New Pane sheet. Custom flags are also supported.

Session persistence — tabs and pane names are saved and restored on relaunch. Any pane whose worktree still exists on disk is restarted automatically.

Keyboard shortcuts:

• ⌘T — new tab
• ⌘P — new pane
• ⌘W — close active pane
• ⌘K — close active tab
• ⌘1–⌘9 — switch to tab by index

Observability / Debugging — unified logs (Console.app / log stream) and Instruments signposts are always on, no setup needed. Enable Settings → Debug → Enable Debug Mode for durable trace/invariant JSONL files and the Trace (⌘⇧D) and Invariant (⌘⇧I) dashboards.
