Dispatch Worker

Compile a worker dispatch spec through node_dispatch_worker and spawn a background agent.

Announce at start: "I'm using the dispatch-worker skill."

Autonomous execution: No human confirmation gate. --dry-run is the only preview mechanism.

Worker Behavior

Required for all dispatched workers — enforced by _COMMON_PREAMBLE in
omnimarket/src/omnimarket/nodes/node_dispatch_worker/handlers/handler_dispatch_worker.py.
Operating rule 4's final local test command is env -u PYTHONPATH uv run pytest tests/ -v.

• Ack after each deliverable. After every discrete deliverable (design doc written, test
  run complete, PR opened, finding logged), send a one-line SendMessage to {reports_to}.
  Never batch acks across multiple deliverables.
• Stop after primary task. When the primary task is complete, send exactly:
  "Primary task done — awaiting further instruction or shutdown." then stop.
  Ambient-idle looping after task completion is forbidden.

Dispatch record persistence ()

Immediately after the node compiles the worker prompt and before Agent() is
spawned, write a ModelDispatchRecord to
$ONEX_STATE_DIR/dispatches/<agent-id>.yaml so downstream hooks
(allowedTools audit, tool-call usage audit, consecutive-failure halt) can
reason about the dispatch:

from datetime import datetime, timezone
from omniclaude.hooks.lib.dispatch_record_writer import write_dispatch_record
from omniclaude.hooks.model_dispatch_record import ModelDispatchRecord

write_dispatch_record(
    ModelDispatchRecord(
        agent_id=spec["name"],
        dispatched_at=datetime.now(timezone.utc),
        dispatcher="onex:dispatch_worker",
        ticket=spec["targets"][0],
        allowed_tools=spec.get("allowedTools", []),
        prompt_digest=prompt_digest,
        parent_session_id=parent_session_id,
    )
)

The PostToolUse post_tool_use_subagent_tool_log.sh hook appends a JSONL
line per subagent tool call to
$ONEX_STATE_DIR/dispatches/<agent-id>/tool-calls.jsonl when
ONEX_AGENT_ID is set in the subagent environment.

Worker Operating Rules (worker_template_version: v2)

The Operating Rules are injected verbatim into every worker prompt by prompt.md
before spawning. They are auto-injected — dispatchers MUST NOT hand-restate them.

They are defined once, canonically, and referenced here rather than restated:

@_lib/dispatch-laws/helpers.md

This file previously carried a second hand-maintained copy which had drifted from the
injected block: it declared itself verbatim, undercounted the rules, dropped one
entirely, and abridged two others. Do NOT restate them here again.
