UI tour

The Zagens desktop window is roughly: icon rail (IconRail) + collapsible session strip, chat, and workspace / tool panels. Since v0.8.3 the chrome is minimal; harness status often appears as floating cards.

Icon rail & sidebar

Entry	Role
New chat / session strip	Start or switch sessions; in-progress indicator while a turn streams in the background
Workspace	File tree and preview
Browser	Built-in Browser (`Ctrl+Shift+B`)
Night queue	Batch jobs & gates
Agent health	Tool / harness telemetry
Usage	Token and cost charts
Tasks	Background tasks & skills; open the full chat from a task card
Sandbox	Windows sandbox first-run wizard (recommended in Code) — Windows sandbox
Sub-agents / checklist	CRAFT / long-horizon checklist (Code)
Settings	Models, MCP, skills, Hooks, Scheduled tasks, approval, LHT, security, …
Theme / language	Light → Dark → Dusk cycle; four UI locales — UI language

The footer shows runtime sidecar connection status. Focus mode: Mod+. (hide secondary chrome).

Chat (center)

Composer — goals, LHT chip, Trace / session JSON export
Streaming timeline — interleaved thinking / tools / prose; long turns collapse into a “work process” row — Streaming
Stop — cancel the active turn (switching sessions does not cancel background parallel turns)
Context — usage estimate; desktop has a Context Explorer breakdown

Some tools open an approval dialog.

Workspace panel (right)

Code mode typically includes:

File tree and preview (code, Markdown, HTML visual, images, CSV, …)
Diff after edits
Embedded terminal (Ctrl+` / Ctrl+Shift+`) — Terminal
Browser view (embed or separate window)

Office mode emphasizes deliverables and Office preview; engineering shell/terminal are narrowed.

Audit & harness (Code)

Long-horizon work may show checklist, audit scratchpad, LHT, and sub-agent cards or grid. See LHT · CRAFT.

Task types

Choosing Code or Office changes tools and system prompts. Switching task type starts a new session. See Task types.
