Arm the target button in the composer and the next prompt becomes a goal:
the server keeps the session working toward it (idle tick -> small-model
audit -> continuation) until the objective is verifiably complete, blocked,
or out of budget — even with the UI closed.
Server (packages/web/server/lib/session-goal):
- event-driven loop on the global SSE hub; goal state lives in
session.metadata.openchamber.goal (merge-safe patches, stale-write guard
by goal id), so it survives restarts and syncs to every client for free
- the small-model audit (objective + last assistant turn only, language
pinned to the objective) is the sole termination authority; blocked needs
3 consecutive verdicts, audit outages tolerate one unaudited continuation
then stop the goal as resumable-blocked
- hard stops: optional token budget, auto-continuation cap (Resume grants a
fresh allowance), turn errors; user abort pauses the goal instead of
blocking it, and resuming over an aborted tail nudges immediately
- token accounting as a snapshot of the latest turn (input + cache.read +
output), goal-relative via a creation baseline and segmented across
compactions; a compaction summary skips the audit and continues
- continuations reuse the session's own provider/model/agent/variant
UI:
- three-mode target button (arm / disarm / manage dialog), informational
goal strip with inline pause/resume and an Evaluating indicator, sidebar
state glyph, objective length counter (2000-char server clamp),
read-only completed goals
- goal entry points: composer (sessions and drafts), start-new-session-
from-answer dialog, plan implement dialog (plan content becomes the
objective), scheduled tasks (Run as goal + budget)
- Settings -> Chat -> Goal: feature toggle + default token budget with
three-layer parity (web server, client persistence, VS Code bridge);
VS Code renders goal state but hides the entry points (the loop runs in
the web server only)
Notifications: per-turn "ready" notifications are suppressed while a goal
is active; settling sends one final notification (desktop, web-push, APNs
generic titles with the session name as body) honoring the completion
toggle. Error/question/permission notifications are untouched.

startup enable snapshots your current environment into the native service so startup behaves like you launched openchamber from the same shell. This preserves provider tokens, PATH, SSH agent settings, and other CLI auth/config env vars. Use --no-env-snapshot if you want a minimal service env.
This runs OpenChamber as an API-only server without the desktop app or browser UI assets on that machine, then creates a link for Desktop to import. --lan makes the server reachable from other machines. --server is the address Desktop should use.
When OpenChamber was started with --lan or --host 0.0.0.0, connect-url automatically uses a detected LAN IP instead of 127.0.0.1. Use --server http://host:3000 to override the advertised address, and include --lan when connect-url needs to start the server for LAN access.
Paste the printed openchamber://connect?... link in Desktop under Settings -> Remote Instances -> Direct Instances -> Import Link. The link contains the server URL and a client token. It does not enable browser UI password protection; use --ui-password when exposing a server beyond localhost.
systemd service (VPN / LAN access)
Run OpenChamber and OpenCode as separate persistent services — useful when you want to access your
dev machine over a VPN (e.g. Tailscale) or LAN without a Cloudflare tunnel.
How it works:
OpenCode runs as its own service, binding only to localhost.
OpenChamber connects to it via OPENCODE_HOST and --lan makes it reachable on your VPN IP.
--foreground keeps the CLI process alive so systemd can track and restart it.
Why set PATH and SSH_AUTH_SOCK?
systemd user services start with a minimal environment — no shell profile is sourced.
Without an explicit PATH, OpenCode won't find tools installed via Homebrew, npm, or ~/.local/bin.
Without SSH_AUTH_SOCK, git operations over SSH (push, pull, clone) will fail because the agent socket isn't inherited.
Adjust the PATH to match your own tool installation paths.
%t expands to $XDG_RUNTIME_DIR (e.g. /run/user/1000), where most SSH agents write their socket.
OpenChamber will be reachable at http://<your-vpn-hostname>:3000 from any device on your VPN.
Note:--host 0.0.0.0 is required to listen on all interfaces. The default
bind address is 127.0.0.1 (localhost only). Use --host <ip> or
OPENCHAMBER_HOST=<ip> to bind to a specific interface instead.
Managed-local path note: OPENCHAMBER_TUNNEL_CONFIG must point to a path inside the container user home (/home/openchamber/...). If your Cloudflare config references a credentials JSON file, that file path must also be accessible inside the container (mount with volumes).

Tunnel behavior notes
OpenChamber supports one active tunnel per running instance (port).
Starting a tunnel with a different mode/provider on the same instance replaces the current tunnel.
Replacing or stopping a tunnel revokes existing connect links and invalidates remote tunnel sessions for that instance.
Connect links are one-time tokens; generating a new link revokes the previous unused link.
Data Directory Permission Note: The data/ directory is mounted into the container for persistent storage (config, sessions, SSH keys, workspaces). Before running, ensure the directory exists and has proper permissions:
My wife, who - with zero AI background - sat down with the app for the first time and built the firework celebration that plays on every successful push.
Every contributor who shaped this project with their PRs, ideas, and attention to detail.
