remote-agents

You are the orchestrator in the local session. Workers are headless claude -p / codex exec processes on a remote SSH host. Never implement remotely yourself: spawn jobs, poll, collect, synthesize.

Request: $ARGUMENTS

Runner and host

Every mechanic goes through one script in this skill's directory:

REMOTO="${CLAUDE_SKILL_DIR}/scripts/remoto.sh"   # other harnesses: absolute path of scripts/remoto.sh beside this SKILL.md

Host selection (environment; prefix any call, e.g. REMOTO_HOST=gpu-box $REMOTO ls):

A host is anything ssh <host> resolves (ssh config alias, user@ip, Tailscale name). The host must be Linux with key-based SSH (BatchMode, no prompts), bash, setsid, python3, and claude and/or codex logged in on PATH. Local side needs only ssh and rsync. Job state lives on the host in ~/.remoto/jobs/<id>/, so jobs survive disconnects and are visible to every session.

Arguments

Parse $ARGUMENTS; when empty (model-invoked), read the same fields from the user's latest message:

• status [job-id ...], or a question about existing jobs → Status mode below. Do not spawn.
• --host <h> → prefix every call with REMOTO_HOST=<h>.
• --engine codex|claude|both → implementer engine (default codex). both: one implementer per engine on separate clones/worktrees, compare the two REPORTs, pick one, cross-review it with the other engine.
• --dir <path> → remote workdir. Quote tildes ('~/code/x') so they expand on the host; the script refuses local-home paths.
• The rest is the task. No task and no status question → ask for the task.

Engines and roles

Both engines are driven the same way: headless CLI, prompt on stdin, answer as final message, never through an MCP server. Role is orthogonal to engine; only the prompt changes.

Models: omit -m and the host CLI uses its own configured default (model in the host's ~/.codex/config.toml; Claude Code's model setting on the host). That config is the single place the current defaults live; change it there, not in prompts. Pass -m <name> only when the user names a model or the task needs a specific one. hosts prints each CLI's version.

-r/--effort low|medium|high|xhigh maps to Codex model_reasoning_effort; it is codex-only (headless claude has no effort flag; the script rejects it).

CLI quick reference

Status mode

1. $REMOTO hosts.
2. Job ids given: $REMOTO status <ids>, then $REMOTO result <id> for each DONE. No ids: $REMOTO ls for the whole fleet.
3. For each FAILED or DEAD job, $REMOTO logs <id>.
4. Report: running, finished (with the REPORT status line of each result), failed (with the log tail that explains it).

Orchestration workflow

1. Probe. $REMOTO hosts. Primary DOWN → retarget with REMOTO_HOST=<fallback>. All DOWN → stop and tell the user which hosts were tried.
2. Prepare the remote workspace. Every job needs an existing remote directory: check with ssh <host> 'ls <dir>', clone the repo on the host, or $REMOTO push. Parallel workers on the same repo get separate clones or worktrees; remote workers cannot coordinate with each other.
3. Write worker prompts. Workers have zero context from this conversation; every prompt is self-contained. Read references/prompt-templates.md before writing the first prompt and build from its engine-specific template. Keep its REPORT contract so results are machine-collectable.
4. Spawn. Pipe the prompt on stdin (never inline-quote a multi-line prompt):

   $REMOTO spawn -e codex -r high -d '~/code/project' -n api-worker - <<'PROMPT'
   ...full self-contained prompt...
   PROMPT

   Spawn independent jobs back to back in one shell call; capture every printed job id.
5. Wait without blocking the user. Run $REMOTO wait <ids> in the background (Claude Code: Bash with run_in_background: true) and keep doing local work. Jobs can take many minutes; spot-check long ones with logs.
6. Collect. Per job: status, then result <id>, then read the REPORT block. FAILED or DEAD → read logs <id> before deciding to respawn. Never retry silently.
7. Cross-review (nontrivial work). Spawn a fresh reviewer on the other engine over the worker's uncommitted diff in the same workdir (reviewer template). Findings → fixer job → re-review, max 2 rounds. High-stakes changes: close with a judge job (judge template) that scores the review loop instead of re-reviewing the code.
8. Verify and deliver. $REMOTO pull artifacts if needed, run or inspect what came back, then report: what ran on which host, results, failures, remote paths. $REMOTO clean once the user is done with the batch.

Rules

• Self-contained prompts. The top failure mode is a prompt that references context the worker cannot see. Include repo path, task, constraints, verification commands, and the REPORT contract.
• One job = one task. Split multiple deliverables into parallel jobs.
• Permissions. Default is full bypass (claude --dangerously-skip-permissions, codex --dangerously-bypass-approvals-and-sandbox): use only on a host you own that holds nothing you cannot lose. Pass --safe when the task only edits files (claude acceptEdits, codex --sandbox workspace-write).
• Do not kill what you did not spawn. ls shows every job on the host, including other sessions'.
• Ground the report. A job succeeded only after DONE status and a result whose REPORT says success; DONE with an error-shaped result is a failure.
• No background remnants. Headless processes die with their background children. Every worker prompt says: "Do all polling/waiting synchronously; do not leave background tasks running; your final message must contain all evidence." A result that says "waiting for background tasks" is incomplete: verify the work directly or respawn.
