Worker

The lead will see your message in:

<team_state_root>/team/<teamName>/mailbox/leader-fixed.json

Use CLI interop:

• omx team api send-message --input <json> --json with {team_name, from_worker, to_worker:"leader-fixed", body}

Copy/paste template:

omx team api send-message --input "{\"team_name\":\"<teamName>\",\"from_worker\":\"<workerName>\",\"to_worker\":\"leader-fixed\",\"body\":\"ACK: <workerName> initialized\"}" --json

Inbox + Tasks

1. Resolve canonical team state root in this order:
   1. OMX_TEAM_STATE_ROOT env
   2. worker identity team_state_root
   3. team config/manifest team_state_root
   4. local cwd fallback (.omx/state)
2. Read your inbox: <team_state_root>/team/<teamName>/workers/<workerName>/inbox.md
3. Pick the first unblocked task assigned to you.
4. Read the task file: <team_state_root>/team/<teamName>/tasks/task-<id>.json (example: task-1.json)
5. Task id format:
   • The MCP/state API uses the numeric id ("1"), not "task-1".
   • Never use legacy tasks/{id}.json wording.
6. Claim the task (do NOT start work without a claim) using claim-safe lifecycle CLI interop (omx team api claim-task --json).
7. Do the work.
8. Complete/fail the task via lifecycle transition CLI interop (omx team api transition-task-status --json) from in_progress to completed or failed.
   • Do NOT directly write lifecycle fields (status, owner, result, error) in task files.
9. Use omx team api release-task-claim --json only for rollback/requeue to pending (not for completion).
10. Update your worker status: <team_state_root>/team/<teamName>/workers/<workerName>/status.json with {"state":"idle", ...}

Mailbox

Check your mailbox for messages:

<team_state_root>/team/<teamName>/mailbox/<workerName>.json

When notified, read messages and follow any instructions. Use short ACK replies when appropriate.

Note: leader dispatch is state-first. The durable queue lives at: <team_state_root>/team/<teamName>/dispatch/requests.json Hooks/watchers may nudge you after mailbox/inbox state is already written.

Use CLI interop:

• omx team api mailbox-list --json to read
• omx team api mailbox-mark-delivered --json to acknowledge delivery

Copy/paste templates:

omx team api mailbox-list --input "{\"team_name\":\"<teamName>\",\"worker\":\"<workerName>\"}" --json
omx team api mailbox-mark-delivered --input "{\"team_name\":\"<teamName>\",\"worker\":\"<workerName>\",\"message_id\":\"<MESSAGE_ID>\"}" --json

Dispatch Discipline (state-first)

Worker sessions should treat team state + CLI interop as the source of truth.

• Prefer inbox/mailbox/task state and omx team api ... --json operations.
• Do not rely on ad-hoc tmux keystrokes as a primary delivery channel.
• If a manual trigger arrives (for example tmux send-keys nudge), treat it only as a prompt to re-check state and continue through the normal claim-safe lifecycle.

Shutdown

If the lead sends a shutdown request, follow the shutdown inbox instructions exactly, write your shutdown ack file, then exit the Codex session.
