Add a shared OpenChamber control service with two thin adapters — a native
`openchamber` tool injected into managed OpenCode, and new CLI commands — so
users can manage parallel sessions, worktrees, and scheduled tasks
conversationally through agents or from the terminal.
Control plane:
- New openchamber-control service owning a fixed action contract:
projects.list, models.list, session list/create/send/fork/status/messages,
and schedule list/create/run/delete/toggle. Session and worktree deletion
and project registration are deliberately not exposed.
- New openchamber-sessions module owning create/worktree/prompt orchestration,
Goal Mode dispatch, wait semantics (initial idle never counts as completion;
timeout and cancellation are failures), and explicit partial-failure results.
- Scheduled-task logic extracted into a service shared by routes, CLI, and the
agent tool.
Agent tool:
- Managed OpenCode gets a materialized plugin registering one typed tool with
a loopback-only callback, per-child ephemeral bearer (timing-safe, never
persisted or logged), and abort propagation into the service.
- The ~1.5k-token schema applies progressive disclosure: short descriptions,
server-side validation returning actionable usage errors, and intent
guardrails — created sessions/tasks are user-facing work (not age
self-delegation); worktree/goal/agent/variant/wait are omit-by-default;
dispatches produce no completion notification, and later result r
to session.messages, which now returns the authoritative sessionStatus.
- session.create without a user-named model picks from favorites/re
send/fork omit the selection and the service reuses the target session's
last user-message model, agent, and variant before falling back t
- An "Agent control tool" setting (default on, Save + Reload to apply)
disables plugin injection entirely.
CLI:
- New `openchamber session`, `schedule`, `projects`, and `models` commands
with automatic instance targeting, --wait/--timeout/--last-assist
worktree flags, and Goal Mode, preserving interactive, non-TTY, --quiet,
and --json contracts. The control HTTP timeout derives from the w
instead of the 4-second default.
UI:
- New built-in "Schedule a Task" starter (/schedule-task) running a
dialogue that defines a task and offers to create it via the tool after
explicit confirmation; Craft a Goal and Feature Planning gain the
handoff offer, and guided starters reserve the question tool for concrete
option choices. Localized in all 10 locales, migrated into custom
starter lists, hidden on VS Code.
- Sidebar shows CLI/agent-created sessions live via the control eve
- openchamber tool calls render with per-action titles and metadata.
linux-x86_64.AppImage for 64-bit Intel or AMD systems
linux-arm64.AppImage for ARM64/aarch64 systems
Make the AppImage executable before launching it, for example with chmod +x <downloaded-appimage>. Keep the AppImage in a location your user can write to so OpenChamber can download and apply in-app updates.
Linux AppImages need FUSE (libfuse.so.2). On Ubuntu/Debian install libfuse2 (or fuse / libfuse2t64 on newer releases). If FUSE is unavailable, run with extraction instead:

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:
