This skill implements the team worker protocol for tmux-based OMX teams, handling startup acknowledgment, mailbox communication, and task lifecycle management. It enables coordinated multi-agent workflows by standardizing how workers register with team leads, receive task assignments, and report completion status. Developers should use this when building or integrating agents that participate in OMX team structures requiring structured inter-agent communication and task coordination.
Worker Skill
This skill is for a Codex session that was started as an OMX Team worker (a tmux pane spawned by $team).
Identity
You MUST be running with OMX_TEAM_WORKER set. It looks like:
<team-name>/worker-<n>
Example: alpha/worker-2
Startup Protocol (ACK)
- Parse
OMX_TEAM_WORKERinto:teamName(before the/)workerName(after the/, usuallyworker-<n>)
- Send an ACK to the lead mailbox:
- Recipient worker id:
leader-fixed - Body: one short line including your workerName and what you’re ready to do.
- Recipient worker id:
- After ACK, proceed to your inbox instructions.
The lead will see your message in:
<team_state_root>/team/<teamName>/mailbox/leader-fixed.json
Use the MCP tool:
team_send_messagewith{team_name, from_worker, to_worker:"leader-fixed", body}
Inbox + Tasks
- Resolve canonical team state root in this order:
OMX_TEAM_STATE_ROOTenv- worker identity
team_state_root - team config/manifest
team_state_root - local cwd fallback (
.omx/state)
- Read your inbox:
<team_state_root>/team/<teamName>/workers/<workerName>/inbox.md - Pick the first unblocked task assigned to you.
- Read the task file:
<team_state_root>/team/<teamName>/tasks/task-<id>.json(example:task-1.json) - Task id format:
- The MCP/state API uses the numeric id (
"1"), not"task-1". - Never use legacy
tasks/{id}.jsonwording.
- The MCP/state API uses the numeric id (
- Claim the task (do NOT start work without a claim). Use the team state APIs described in your inbox/overlay.
- Do the work.
- Write completion to the task file:
{"status":"completed","result":"..."}or{"status":"failed","error":"..."}
- Update your worker status:
<team_state_root>/team/<teamName>/workers/<workerName>/status.jsonwith{"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.
Use MCP tools:
team_mailbox_listto readteam_mailbox_mark_deliveredto acknowledge delivery
Shutdown
If the lead sends a shutdown request, follow the shutdown inbox instructions exactly, write your shutdown ack file, then exit the Codex session.
