Summary

Remote container support — dispatch AI workers to containers on remote hosts via SSH/Tailscale, with credential forwarding and log collection.

Ref #1765

Changes

New: remote-dispatch-helper.sh (1057 lines)

  • Host management: add, remove, hosts, check commands for configuring remote hosts
  • SSH + Tailscale transport: Auto-detects Tailscale addresses (*.ts.net, 100.x.x.x), uses tailscale ssh when available, falls back to regular SSH
  • Credential forwarding: SSH agent forwarding (-A) for git auth, API key env vars (GH_TOKEN, ANTHROPIC_API_KEY, OPENROUTER_API_KEY, GOOGLE_API_KEY)
  • Remote dispatch: Creates workspace on remote, clones repo, generates dispatch/wrapper scripts, starts worker via nohup/setsid (or docker exec for container targets)
  • Log collection: Stream (--follow) and batch collection from remote hosts
  • Status monitoring: Check remote worker PID, completion signals, log size
  • Cleanup: Kill remote processes, collect logs, remove workspace

Modified: supervisor/dispatch.sh

  • cmd_dispatch(): Detects dispatch_target column on tasks, routes to remote-dispatch-helper.sh instead of local process spawn
  • cmd_worker_status(): Handles remote:host:pid PID format for remote workers
  • Remote host connectivity check before dispatch (defers on failure)

Modified: supervisor/pulse.sh

  • Phase 1: Detects remote PID format, checks remote worker status via helper
  • Auto-collects remote logs before evaluation when remote worker finishes
  • Updates task log_file to local copy for normal evaluation flow

Modified: supervisor/database.sh

  • Migration: dispatch_target TEXT DEFAULT NULL column on tasks table
  • Init schema: Same column in CREATE TABLE tasks

New: tools/containers/remote-dispatch.md

  • Full subagent documentation with architecture diagram, usage examples, troubleshooting
  • Updated subagent-index.toon, AGENTS.md domain index, headless-dispatch.md cross-reference

Code Review

The pull request introduces a robust remote container dispatch system, allowing AI workers to run on remote hosts via SSH or Tailscale. The implementation includes host management, credential forwarding, and automated log collection integrated into the supervisor's pulse loop. The code generally follows the project's shell scripting standards, though there are some opportunities to improve adherence to the style guide regarding temporary file handling and explicit return statements. Security-wise, ensuring restricted permissions on the remote workspace is recommended to protect forwarded API keys.

The remote workspace is created in /tmp and will contain dispatch.sh, which includes sensitive API keys. To prevent exposure to other users on the remote host, the directory should be created with restricted permissions (e.g., 700).

Temporary files must be cleaned up using the established project pattern: _save_cleanup_scope, trap '_run_cleanups' RETURN, and push_cleanup for robust cleanup on any exit path. The current direct trap should be replaced with an integration into this project-specific cleanup mechanism.

  2. For resource cleanup in shell scripts, use the established project pattern: use _save_cleanup_scope, trap '_run_cleanups' RETURN, and push_cleanup for robust cleanup on any exit path, and also include explicit manual cleanup at the end of the normal execution path as a 'fast-path'.

Suppressing stderr with 2>/dev/null is redundant here because the existence of $meta_file has already been verified on the preceding line. Avoiding unnecessary suppression helps in identifying other potential issues like permission errors.

Suggested change

remote_log_file=$(jq -r '.remote_log_file' "$meta_file" || echo "$remote_log_file")
References
  1. Avoid using 2>/dev/null to suppress errors on file operations if the file's existence has already been verified by a preceding check. This practice is redundant for 'file not found' errors and can mask other important issues like permissions problems.

412-435: _build_remote_command_with_creds is defined but never called — dead code.

Credential forwarding in cmd_dispatch is done directly via cred_env_str embedded in the dispatch heredoc. This helper is entirely unused.

3264-3270: Connectivity check before remote dispatch is a good defensive pattern, but consider logging the check output on failure.

3249-3294: Remote dispatch block is placed after local wrapper/dispatch script generation — unnecessary work for remote targets.

Lines 3159–3247 build the local dispatch_script and wrapper_script (including the worktree creation at line 2942), but these are never used when dispatch_target is set. Moving the remote-dispatch check earlier (e.g., right after the model resolution block) would skip worktree creation, MCP config generation, and local script generation for remote targets — saving I/O and reducing code path complexity.

This isn't a correctness issue, but as the remote dispatch path grows, the wasted setup becomes more significant (worktree creation involves git worktree add).

♻️ Suggested restructure: move remote check earlier

Move the remote dispatch target check (lines 3249–3294) to just after the model resolution and recording block (~line 3104), before the local dispatch script generation starts. You'd need to keep the model resolution, health checks, and the resolved_model assignment, but skip worktree creation and local script generation entirely for remote targets.

107-132: Supervisor integration section shows raw sqlite3 for setting dispatch_target — note the lack of CLI wrapper.

Line 123–126 instructs users to run raw sqlite3 commands against the supervisor DB. This is functional but fragile (no validation, easy to mistype). The "Future" note on line 132 about TODO.md integration is good. Consider also noting that a supervisor-helper.sh set-target <task_id> <host> CLI command would be a natural next step, so users know this is intentional and not an oversight.

(1) copy the host-side wrapper into the container (use docker cp via the ssh_cmd
session or copy into a container-accessible path) or alternatively run the
wrapper on the remote host but update the wrapper to invoke docker exec
internally; and (2) obtain the real in-container worker PID instead of the
short-lived helper PID by starting the worker inside the container and echoing
that worker PID back (e.g., after docker exec runs the wrapper that
writes/prints its own PID), then set remote_pid from that real PID so
cmd_status's kill -0 checks work; touch the references remote_wrapper,
remote_pid, ssh_cmd, docker exec and cmd_status when making these changes.

DEFAULT_SSH_OPTS for those targets, or (B) omit/replace DEFAULT_SSH_OPTS when
invoking `tailscale ssh` and introduce a separate TAILSCALE_SSH_OPTS or explicit
behavior for timeouts/host-checking; change references to DEFAULT_SSH_OPTS and
the call site in _build_ssh_cmd() to conditionally choose the command and
options accordingly so ConnectTimeout/StrictHostKeyChecking/ServerAliveInterval
are applied only to real ssh invocations.

In @.agents/scripts/supervisor/dispatch.sh:
- Around line 3274-3280: The current remote dispatch failure block always calls
cmd_transition "$task_id" "failed" and returns 1; change it to inspect the
helper's exit code (the value of $? inside the failure branch) and treat
transient/availability codes (e.g., 3 as used elsewhere for "defer") as a defer:
call cmd_transition "$task_id" "deferred" or use the same --error payload but
then return 3; for other non-transient/permanent exit codes keep the existing
failed transition and return 1. Locate the failure handler around the
remote_helper dispatch invocation (remote_pid=$("$remote_helper" dispatch ... )
|| { ... }) and implement the conditional branching on the helper exit code,
preserving logging to SUPERVISOR_LOG and including the dispatch_target and
task_id in messages.
- Around line 3282-3284: The PID file and session string are fragile because
they join remote:${dispatch_target}:${remote_pid} with colon-delimited parsing
used later by cmd_worker_status; update the write and parsing so the PID is
unambiguous — either switch the delimiter to a safe char (e.g., use '|' when
writing echo "remote|${dispatch_target}|${remote_pid}" to
SUPERVISOR_DIR/pids/${task_id}.pid and to the session string passed to
cmd_transition), or keep the colon but change consumers to extract the PID and
host by parsing the last colon-separated field for PID and everything between
"remote:" and the last ":" for host (update where cmd_worker_status reads
fields). Ensure cmd_transition call and PID file use the same 3- or 4-field
format consistently (reference variables dispatch_target, remote_pid,
cmd_transition, and cmd_worker_status).

In @.agents/scripts/supervisor/pulse.sh:
- Around line 1210-1235: The handling of "remote:host:pid" is only implemented

stale_has_live_worker (Phase 0.7), stuck_alive (Phase 1c), the Phase 4 health
check that runs rm -f "$pid_file" and then
cmd_evaluate/cmd_transition("failed"), and the live_pid_count computation —
detect if pid starts with "remote:", parse host and remote pid like the existing
block (use SCRIPT_DIR/../remote-dispatch-helper.sh), call the helper with status
to decide liveness (and collect logs via logs when transitioning), set the same
is_alive/stale_has_live_worker/stuck_alive/live_pid_count behavior as local
PIDs, and skip rm -f and local kill -0 for remote entries so remote workers are
not misidentified as dead.
- Around line 1230-1232: The current logic leaves is_alive=false when
remote-dispatch-helper.sh is not executable, causing remote tasks to be treated
as dead; update the remote task branch so that when the helper cannot be invoked
(the branch that currently calls log_warn "  $tid: remote-dispatch-helper.sh not
found, cannot check remote worker") you set is_alive=true (conservative default)
and skip transitioning the task to retry/failed; only run the existing remote
health-check flow when the helper executes successfully, and keep the existing
local PID check (the elif kill -0 "$pid" branch) unchanged for non-remote PIDs.
- Around line 1213-1214: Remove the dead _remote_pid extraction: change the
local declaration that extracts remote:host:pid to only assign the host (use

and add a brief caveat for security-conscious deployments; also clarify the
exact transport mechanism used by the helper (whether it relies on SSH
AcceptEnv/SendEnv or uses inline exported variables like VAR=val command) so
readers know if SSH server/client env propagation can silently fail.
- Around line 262-269: Update the npm install line to use the current package
name: replace the existing `npm install -g `@anthropic-ai/claude-code`` invocation

https://opencode.ai/install | bash`) unchanged.

Nitpick comments:
In @.agents/scripts/remote-dispatch-helper.sh:
- Around line 412-435: The helper function _build_remote_command_with_creds is
dead code; either remove it or wire it into cmd_dispatch to centralize
credential-forwarding logic: update cmd_dispatch to stop embedding cred_env_str
directly in the heredoc and instead call
_build_remote_command_with_creds(remote_command) to produce the final command
(or delete _build_remote_command_with_creds if you prefer removal), and ensure
any remaining uses of cred_env_str are removed so there’s a single source of
truth for credential env construction.

In @.agents/scripts/supervisor/dispatch.sh:
- Around line 3264-3270: The connectivity check currently discards output;
change the call to capture the command's stderr/stdout (e.g., into a variable
like check_output) when invoking "$remote_helper" check "$dispatch_target",
preserve remote_check_rc on failure, and include the captured output in the
log_error message so operators see the actual failure reason; update references
around remote_helper, dispatch_target, remote_check_rc, and log_error to use the
new check_output variable when logging.
- Around line 3249-3294: The remote-dispatch detection and handling (the block
using dispatch_target, remote-dispatch-helper.sh, remote_check_rc, remote_pid,
cmd_transition and add_model_label) should be moved earlier — directly after
model resolution and recording (i.e., after resolved_model is set) and before
any local worktree/mcp/wrapper/dispatch_script generation; update the script so
that once dispatch_target is non-empty you perform the remote connectivity check
and remote dispatch flow there and return early, thereby skipping git worktree
creation and local script generation for remote targets.

In @.agents/tools/containers/remote-dispatch.md:
- Around line 107-132: The docs show a raw sqlite3 command to set
dispatch_target directly in the supervisor DB which is fragile; update the
.agents/tools/containers/remote-dispatch.md supervisor integration section to
replace or augment the raw sqlite3 example with a note recommending a CLI
wrapper (e.g., introduce a suggested supervisor-helper.sh set-target <task_id>
<host> command) and mention that cmd_dispatch() will read dispatch_target and
that the recommended CLI will validate input, sanitize task IDs, and error on
missing tasks to avoid direct DB edits; keep the raw sqlite3 example as an
advanced fallback but mark it as "advanced/unsafe" and point readers to
remote-dispatch-helper.sh and cmd_dispatch() for normal usage.

tailscale ssh support standard OpenSSH client options -o ConnectTimeout StrictHostKeyChecking

💡 Result:

  • If you want standard OpenSSH client options (-o ConnectTimeout=…, -o StrictHostKeyChecking=…, etc.): use your normal ssh client to connect to the Tailscale hostname/IP (for example ssh user@device or ssh user@100.x.y.z). Tailscale SSH is designed so you can “SSH as normal” with your existing SSH client, and it manages distribution/handling of SSH host keys (including a Tailscale-managed known_hosts) to make this work. (tailscale.com)

    Example:

    ssh -o ConnectTimeout=5 -o StrictHostKeyChecking=accept-new user@device
  • If you use the tailscale ssh … subcommand: it is not just a thin wrapper around OpenSSH, and people commonly observe that OpenSSH flags like -o StrictHostKeyChecking=no are ignored when passed to tailscale ssh. (github.com)

So: use ssh … -o … (regular OpenSSH) when you need OpenSSH options; reserve tailscale ssh for cases where you specifically need the Tailscale-built SSH client behavior. (tailscale.com)

Citations:


SSH options silently ignored by tailscale ssh — refactor to use standard SSH client or conditionally set options.

Line 33 defines DEFAULT_SSH_OPTS with -o ConnectTimeout=10 -o StrictHostKeyChecking=accept-new -o ServerAliveInterval=30, which is appropriate for standard SSH. However, when _build_ssh_cmd() dispatches via Tailscale (lines 240–253), these options are passed directly to the tailscale ssh subcommand, which does not support standard OpenSSH -o options and silently ignores them.

This means:

  • ConnectTimeout=10 does not apply (no timeout enforcement)
  • StrictHostKeyChecking=accept-new is not enforced (host key verification disabled)
  • ServerAliveInterval=30 does not apply (no keep-alive)

Fix: Either use regular ssh client with -o options when connecting to Tailscale addresses, or conditionally apply DEFAULT_SSH_OPTS only for direct SSH transport and configure Tailscale SSH behavior separately.

⚠️ Potential issue | 🟠 Major

API keys are written to a world-readable file in /tmp on the remote host.

_build_credential_env assembles ANTHROPIC_API_KEY, GH_TOKEN, OPENROUTER_API_KEY, and GOOGLE_API_KEY as plain export KEY=VALUE shell statements. These are embedded in dispatch_content and uploaded to /tmp/aidevops-worker/${task_id}/dispatch.sh via chmod +x (not chmod 600), making the file readable by all local users on the remote. The keys persist there until cmd_cleanup is called.

The comment at line 405 ("Does NOT forward actual secret values over SSH") is also incorrect and misleading — the implementation does exactly that.

🔒 Proposed fix — restrict permissions immediately after upload
 echo "$dispatch_content" | "${ssh_cmd[@]}" "cat > '${remote_script}' && chmod +x '${remote_script}'" 2>/dev/null || {
     _log_error "Failed to upload dispatch script"
     return 1
 }
+# Restrict to owner-only read/execute so API keys in the script aren't world-readable
+"${ssh_cmd[@]}" "chmod 600 '${remote_script}'; chmod u+x '${remote_script}'" 2>/dev/null || true

 echo "$wrapper_content" | "${ssh_cmd[@]}" "cat > '${remote_wrapper}' && chmod +x '${remote_wrapper}'" 2>/dev/null || {
     _log_error "Failed to upload wrapper script"
     return 1
 }
+"${ssh_cmd[@]}" "chmod 700 '${remote_wrapper}'" 2>/dev/null || true

Longer-term, prefer passing API keys via SSH SendEnv/AcceptEnv or a dedicated secrets manager on the remote, keeping them out of the filesystem entirely.

⚠️ Potential issue | 🟠 Major

Container dispatch is broken in two independent ways.

  1. Wrong filesystem namespace: remote_wrapper is written to the remote HOST at /tmp/aidevops-worker/${task_id}/wrapper.sh. docker exec -d 'container' bash '${remote_wrapper}' evaluates that path inside the container's filesystem, where it doesn't exist unless a /tmp volume is explicitly mounted. This silently fails (all errors suppressed with 2>/dev/null), so cmd_dispatch returns successfully while no actual work was started.

  2. Wrong PID tracking: docker exec -d detaches immediately and exits; the outer nohup ... & process therefore also exits within milliseconds. echo \$! captures the PID of this dead helper, not the in-container worker. All subsequent kill -0 checks in cmd_status will always report the process as dead.

🐛 Recommended approach for container dispatch

Upload the wrapper into the container via docker cp, then exec it:

-remote_pid=$("${ssh_cmd[@]}" "
-    nohup docker exec -d '${container_name}' bash '${remote_wrapper}' &
-    echo \$!
-" 2>/dev/null)
+remote_pid=$("${ssh_cmd[@]}" "
+    docker cp '${remote_wrapper}' '${container_name}:${remote_work_dir}/wrapper.sh' 2>/dev/null &&
+    docker exec -d '${container_name}' bash '${remote_work_dir}/wrapper.sh' &&
+    docker exec '${container_name}' pgrep -f 'wrapper.sh' | tail -1
+" 2>/dev/null)

Alternatively, dispatch directly on the host and let the worker target the container via its own docker exec calls.

user is never saved to dispatch metadata, breaking cmd_status and cmd_cleanup for hosts with a custom SSH user.

cmd_dispatch writes the metadata JSON (lines 695–709) without a user field. Both cmd_status (line 851) and cmd_cleanup (line 958) hardcode local user="" rather than reading from metadata, so _build_ssh_cmd always uses the current OS user. For any host registered with --user pi, --user ubuntu, etc., status and cleanup calls will either connect as the wrong user or fail to connect entirely.

🐛 Proposed fix

In cmd_dispatch, add user to the metadata:

 cat >"$local_meta_file" <<META_EOF
 {
     "task_id": "${task_id}",
     "host": "${host}",
     "address": "${address}",

     "remote_pid": "${remote_pid}",
     ...
 }

In cmd_status and cmd_cleanup, read the field back:

+local user
+user=$(jq -r '.user // ""' "$meta_file" 2>/dev/null || echo "")
 local -a ssh_cmd=()
 while IFS= read -r line; do

Remote PID guard is incomplete — Phase 0.7, Phase 1c, and Phase 4 will misidentify remote workers as dead

The remote:* detection was added only here. Three other phases read PID files and call kill -0 without a matching guard — kill -0 "remote:host:pid" always silently fails because the argument is not numeric:

Phase Location Consequence
Phase 0.7 ~line 991 stale_has_live_worker stays false → remote task re-queued or failed as stale
Phase 1c ~line 1691 stuck_alive stays false → remote task reaped from evaluating prematurely
Phase 4 health ~line 2491 rm -f "$pid_file" fires, then cmd_evaluate/cmd_transition("failed") runs against a still-running remote worker
live_pid_count ~line 2821 Always 0 for remote workers → spurious STATE MISMATCH warnings every pulse

Phase 4 is the most destructive path: it deletes the remote:host:pid PID file (breaking future status checks for that task) and then tries to evaluate a task whose worker is still alive on the remote host.

Each of those PID-liveness checks should extract the stored PID, detect the remote:* prefix, and delegate to remote-dispatch-helper.sh (or at minimum skip kill -0) the same way this block does.

Remove unused _remote_pid variable — dead code

_remote_pid (line 1214) is extracted from the remote:host:pid string but never passed to the helper. The status and logs subcommands accept only <task_id> and <host> arguments; they retrieve the remote PID internally from metadata using the task ID. Delete line 1214 and simplify the variable declaration on line 1212 to local _remote_host.

Also ensure this script runs through ShellCheck (-u flag) as part of pre-commit checks per coding guidelines for .agents/scripts/**/*.sh.

⚠️ Potential issue | 🟠 Major

is_alive defaults to false when helper is unavailable — premature task evaluation on infra failures

When remote-dispatch-helper.sh is not executable the warning is emitted but is_alive stays false, so the task is immediately pushed through the evaluation path as if its worker died. A transient permission change, deployment hiccup, or filesystem issue will cascade into incorrect retrying/failed transitions for every remote task.

The conservative default for an indeterminate remote state is to treat the worker as alive and wait for the next pulse to retry:

🛡️ Proposed fix — treat remote worker as alive when helper is unavailable
-			else
-				log_warn "  $tid: remote-dispatch-helper.sh not found, cannot check remote worker"
-			fi
+			else
+				log_warn "  $tid: remote-dispatch-helper.sh not found or not executable — treating remote worker as alive until helper is available"
+				is_alive=true
+			fi

The AI summary states the code "falls back to the existing local PID check logic" when the helper is missing. It does not — the elif kill -0 "$pid" branch is only reachable for non-remote:* PIDs; the else clause inside the remote:* block has no fallback.

**Security notes**:

- SSH agent forwarding (`-A`) passes the local SSH agent socket, not the keys themselves
- API keys are passed as environment variables to the remote command
- Keys are NOT written to disk on the remote host
- The remote workspace is cleaned up after task completion

⚠️ Potential issue | 🟡 Minor

Security notes should mention /proc/<pid>/environ exposure risk for environment-variable-based credential forwarding.

Line 149 states "Keys are NOT written to disk on the remote host," but environment variables are readable from /proc/<pid>/environ by the same user (and root) on Linux. While acceptable for most use cases, this is worth a brief mention for security-conscious deployments.

Additionally, if the remote SSH session's AcceptEnv or SendEnv isn't configured, the env-var forwarding approach may silently fail — the helper likely uses a different mechanism (e.g., inline VAR=val command), but the docs should clarify the actual transport method.

the "Security notes" section to explicitly mention that
environment-variable-based credential forwarding exposes values to
/proc/<pid>/environ (readable by the same user and root on Linux) so keys aren't
written to disk but can still be read by processes with appropriate privileges,
and add a brief caveat for security-conscious deployments; also clarify the
exact transport mechanism used by the helper (whether it relies on SSH
AcceptEnv/SendEnv or uses inline exported variables like VAR=val command) so
readers know if SSH server/client env propagation can silently fail.

The remote host needs `opencode` or `claude` CLI installed. Install via:

```bash
# On the remote host
npm install -g @anthropic-ai/claude-code
# or
curl -fsSL https://opencode.ai/install | bash
```
