A tour of the interface

Brain card at the top of the sidebar — the chief controller; expand it to see its sessions.
Session list — click to chat; the landing page goes straight to the most recent session. Under the composer: live context usage, and (when the endpoint supports it) per-session model selection and access-mode switching between read-only and workspace-write.
Nodes page (/nodes) — three views: a live topology (manager → machines → nodes, heartbeat edges), the node list (start / stop / restart / logs, plus the New node wizard), and the machine directory for hosts that joined through a node agent.
Runs page (/runs) — every dispatched run across all workspaces, filterable by workspace and state, newest first.
Skills page — what each workspace has installed (version = workspace git HEAD).
Cost page — spend detail, per-workspace and per-model breakdown.
Bell — in-app notifications: offline machine, abnormal node, budget breaker, finished brain dispatch.
⋮ menu — skills / archived / cost / audit / password, the language switcher (English ⇄ 中文) and the GitHub link.

Chat

Multi-turn conversation with streaming output, tool-call cards, and inline question/authorization answers. Concurrent sessions are serial within a session and parallel across sessions, with git commit locks and surfaced conflicts.

Nodes

Adding a node: nodes page → New node → name and workspace path; ports, gateway keys and DSH_HOME are allocated for you. Two shapes:

Container worker (isolated) — runs in a container image (hellodac/dac-node:<version>).
Host process (whole-machine capability) — runs on the host with a risk warning and audit; its dependencies install into its own directory, never the global npm.

Every node row carries a Native GUI card: one SSH tunnel command (the key stays on your machine) plus a one-click open of the node's native UI. Local nodes (loopback endpoints) skip the tunnel — one click opens the native UI directly.

Each node's DSH version is pinned against a version matrix; the nodes page shows the configured version plus drift state, and one click aligns it.

Skills

A skill is a .skills/<name>/SKILL.md file inside a workspace. The skills page lists them per workspace; each agent reads its own workspace's skills.

Scheduled runs

Unattended runs are configured through the scheduler API: a schedule, a target node and a task description. Repeated failures disable the schedule instead of burning budget, and brain dispatch stays behind the daily budget breaker.
