skills/team/SKILL.mdTeam Skill
$team is the tmux-based parallel execution mode for OMX. It starts real worker Codex and/or Claude CLI sessions in split panes and coordinates them through .omx/state/team/... files plus CLI team interop (omx team api ...) and state files.
This skill is operationally sensitive. Treat it as an operator workflow, not a generic prompt pattern.
Team vs Native Subagents
- Use Codex native subagents for bounded, in-session parallelism where one leader thread can fan out a few independent subtasks and wait for them directly.
- Use
when you need durable tmux workers, shared task state, mailbox/dispatch coordination, worktrees, explicit lifecycle control, or long-running parallel execution that must survive beyond one local reasoning burst.omx team - Native subagents can complement team/ralph execution, but they do not replace the tmux team runtime's stateful coordination contract.
What This Skill Must Do
GPT-5.4 Guidance Alignment
- Default to concise, evidence-dense progress and completion reporting unless the user or risk level requires more detail.
- Treat newer user task updates as local overrides for the active workflow branch while preserving earlier non-conflicting constraints.
- If correctness depends on additional inspection, retrieval, execution, or verification, keep using the relevant tools until the team workflow is grounded.
- Continue through clear, low-risk, reversible next steps automatically; ask only when the next step is materially branching, destructive, or preference-dependent.
When user triggers
$team, the agent must:
- Invoke OMX runtime directly with
omx team ... - Avoid replacing the flow with in-process
fanoutspawn_agent - Verify startup and surface concrete state/pane evidence
- If active team mode state is missing, initialize/sync it from canonical team runtime state before proceeding
- Keep team state alive until workers are terminal (unless explicit abort)
- Handle cleanup and stale-pane recovery when needed
If
omx team is unavailable, stop with a hard error.
Invocation Contract
omx team [N:agent-type] "<task description>"
Examples:
omx team 3:executor "analyze feature X and report flaws" omx team "debug flaky integration tests" omx team "ship end-to-end fix with verification"
Team-first launch contract
omx team ... is now the canonical launch path for coordinated execution.
Team mode should carry its own parallel delivery + verification lanes without
requiring a separate linked Ralph launch up front.
- Canonical launch: use plain
/omx team ...
for coordinated workers.$team ... - Verification ownership: keep one lane focused on tests, regression coverage, and evidence before shutdown.
- Escalation: start a separate
/omx ralph ...
only when a later manual follow-up still needs a persistent single-owner fix/verification loop.$ralph ... - Deprecation:
has been removed. Use plainomx team ralph ...
for team execution or runomx team ...
separately when you explicitly want a later Ralph loop.omx ralph ...
Claude teammates (v0.6.0+)
Important:
N:agent-type (for example 2:executor) selects the worker role prompt, not the worker CLI (codex vs claude).
To launch Claude teammates, use the team worker CLI env vars:
# Force all teammates to Claude CLI OMX_TEAM_WORKER_CLI=claude omx team 2:executor "update docs and report" # Mixed team (worker 1 = Codex, worker 2 = Claude) OMX_TEAM_WORKER_CLI_MAP=codex,claude omx team 2:executor "split doc/code tasks" # Auto mode: Claude is selected when worker launch args/model contains 'claude' OMX_TEAM_WORKER_CLI=auto OMX_TEAM_WORKER_LAUNCH_ARGS="--model claude-..." omx team 2:executor "run mixed validation"
Preconditions
Before running
$team, confirm:
installed (tmux
)tmux -V- Current leader session is inside tmux (
is set)$TMUX
command resolves to the intended install/buildomx- If running repo-local
, runnode bin/omx.js ...
afternpm run build
changessrc - Check HUD pane count in the leader window and avoid duplicate
panes before splithud --watch
Suggested preflight:
tmux list-panes -F '#{pane_id}\t#{pane_start_command}' | rg 'hud --watch' || true
If duplicates exist, remove extras before
omx team to prevent HUD ending up in worker stack.
Pre-context Intake Gate
Before launching
omx team, require a grounded context snapshot:
- Derive a task slug from the request.
- Reuse the latest relevant snapshot in
when available..omx/context/{slug}-*.md - If none exists, create
(UTC.omx/context/{slug}-{timestamp}.md
) with:YYYYMMDDTHHMMSSZ- task statement
- desired outcome
- known facts/evidence
- constraints
- unknowns/open questions
- likely codebase touchpoints
- If ambiguity remains high, run
first for brownfield facts, then runexplore
before team launch.$deep-interview --quick <task> - If current correctness depends on official docs, version-aware framework guidance, best practices, or external dependency behavior, auto-delegate
as an evidence lane before or alongside worker launch instead of relying on repo-local recall alone.researcher
Do not start worker panes until this gate is satisfied; if forced to proceed quickly, state explicit scope/risk limitations in the launch report.
For simple read-only brownfield lookups during intake, follow active session guidance: when
USE_OMX_EXPLORE_CMD is enabled, prefer omx explore with narrow, concrete prompts; otherwise use the richer normal explore path and fall back normally if omx explore is unavailable.
Follow-up Staffing Contract
When
$team is used as a follow-up mode from ralplan, carry forward the approved plan's explicit available-agent-types roster and convert it into concrete staffing guidance before launch:
- keep worker-role choices inside the known roster
- state the recommended headcount and role counts
- state the suggested reasoning level for each lane when available
- explain why each lane exists (delivery, verification, specialist support)
- include an explicit launch hint (
/omx team N "<task>"
) for the coordinated team run; mention a later separate Ralph follow-up only when genuinely needed$team N "<task>" - if the ideal role is unavailable, choose the closest role from the roster and say so
Current Runtime Behavior (As Implemented)
omx team currently performs:
- Parse args (
,N
, task)agent-type - Sanitize team name from task text
- Initialize team state:
.omx/state/team/<team>/config.json.omx/state/team/<team>/manifest.v2.json.omx/state/team/<team>/tasks/task-<id>.json
- Compose team-scoped worker instructions file at:
.omx/state/team/<team>/worker-agents.md- Uses project
content (if present) + worker overlay, without mutating projectAGENTS.mdAGENTS.md
- Resolve canonical shared state root from leader cwd (
)<leader-cwd>/.omx/state - Split current tmux window into worker panes
- Launch workers with:
OMX_TEAM_WORKER=<team>/worker-<n>OMX_TEAM_STATE_ROOT=<leader-cwd>/.omx/stateOMX_TEAM_LEADER_CWD=<leader-cwd>- worker CLI selected by
/OMX_TEAM_WORKER_CLI
(OMX_TEAM_WORKER_CLI_MAP
orcodex
)claude - optional worktree metadata envs when
is used--worktree
- Wait for worker readiness (
polling)capture-pane - Write per-worker
and trigger viainbox.mdtmux send-keys - Return control to leader; follow-up uses
/status
/resumeshutdown
If coarse active team mode state is missing while canonical team runtime state exists, restore/sync the active team mode state before relying on hook/mode-aware behavior.
Important:
- Leader remains in existing pane
- Worker panes are independent full Codex/Claude CLI sessions
- Workers may run in separate git worktrees (
) while sharing one team state rootomx team --worktree[=<name>] - Worker ACKs go to
mailbox/leader-fixed.json - Notify hook updates worker heartbeat and nudges leader during active team mode
- Submit routing uses this CLI resolution order per worker trigger:
- explicit worker CLI provided by runtime state (persisted on worker identity/config),
entry for that worker index,OMX_TEAM_WORKER_CLI_MAP- fallback
/ auto detection.OMX_TEAM_WORKER_CLI
- Mixed CLI-map teams are supported for both startup and trigger submit behavior.
- Trigger submit differs by CLI:
- Codex may use queue-first
on busy panes (strategy-dependent).Tab - Claude always uses direct Enter-only (
) rounds (never queue-firstC-m
).Tab
- Codex may use queue-first
Team worker model + thinking resolution (current contract)
Team mode resolves worker model flags from one shared launch-arg set (not per-worker model selection).
Model precedence (highest to lowest):
- Explicit worker model in
OMX_TEAM_WORKER_LAUNCH_ARGS - Inherited leader
flag--model - Low-complexity default from
(legacy alias:OMX_DEFAULT_SPARK_MODEL
) when 1+2 are absent and teamOMX_SPARK_MODEL
is low-complexityagentType
Default-model rule:
- Do not assume a frontier or spark model from recency or model-family heuristics.
- Use
for frontier-default guidance.OMX_DEFAULT_FRONTIER_MODEL - Use
for spark/low-complexity worker-default guidance.OMX_DEFAULT_SPARK_MODEL
Thinking-level rule (critical):
- No model-name heuristic mapping.
- Team runtime must not infer
from model-name substrings (e.g.,model_reasoning_effort
,spark
,high-capability
).mini - When the leader assigns teammate roles/tasks, OMX allocates per-worker reasoning effort dynamically from the resolved worker role (
,low
,medium
).high - Explicit launch args still win: if
already includesOMX_TEAM_WORKER_LAUNCH_ARGS
, that explicit value overrides dynamic allocation for every worker.-c model_reasoning_effort=...
Normalization requirements:
- Parse both
and--model <value>--model=<value> - Remove duplicate/conflicting model flags
- Emit exactly one final canonical flag:
--model <value> - Preserve unrelated args in worker launch config
- If explicit reasoning exists, preserve canonical
; otherwise inject the worker role's default reasoning level-c model_reasoning_effort="<level>"
Required Lifecycle (Operator Contract)
Follow this exact lifecycle when running
$team:
- Start team and verify startup evidence (team line, tmux target, panes, ACK mailbox)
- Monitor task and worker progress with runtime/state tools first (
,omx team status <team>
, mailbox/state files)omx team resume <team> - Wait for terminal task state before shutdown:
pending=0in_progress=0
(or explicitly acknowledged failure path)failed=0
- Only then run
omx team shutdown <team> - Verify shutdown evidence and state cleanup
Do not run
shutdown while workers are actively writing updates unless user explicitly requested abort/cancel.
Do not treat ad-hoc pane typing as primary control flow when runtime/state evidence is available.
Active leader monitoring rule
While a team is ON/running, the leader must not go blind. Keep checking live team state until terminal completion.
Minimum acceptable loop:
sleep 30 && omx team status <team-name>
Repeat that check while the team stays active, or use
omx team await <team-name> --timeout-ms 30000 --json when event-driven waiting is a better fit.
If the leader gets a stale/team-stalled nudge, immediately run
omx team status <team-name> before taking any manual intervention.
Message Dispatch Policy (CLI-first, state-first)
To avoid brittle behavior, message/task delivery must not be driven by ad-hoc tmux typing.
Required default path:
- Use
runtime lifecycle commands for orchestration.omx team ... - Use
for mailbox/task mutations.omx team api ... --json - Verify delivery via mailbox/state evidence (
, task status,mailbox/*.json
).omx team status
Strict rules:
- MUST NOT use direct
as the primary mechanism to deliver instructions/messages.tmux send-keys - MUST NOT spam Enter/trigger keys without first checking runtime/state evidence.
- MUST prefer durable state writes + runtime dispatch (
, mailbox, inbox).dispatch/requests.json - Direct tmux interaction is fallback-only and only after failure checks (for example
) or explicit user request (for example “press enter”).worker_notify_failed:<worker>

Team Mutation Interop (CLI-first)
Use
omx team api for machine-readable mutation/reads instead of legacy team_* MCP tools.
omx team api <operation> --input '{"team_name":"my-team",...}' --json
Examples:
omx team api send-message --input '{"team_name":"my-team","from_worker":"worker-1","to_worker":"leader-fixed","body":"ACK"}' --json omx team api claim-task --input '{"team_name":"my-team","task_id":"1","worker":"worker-1"}' --json omx team api transition-task-status --input '{"team_name":"my-team","task_id":"1","from":"in_progress","to":"completed","claim_token":"<token>"}' --json

Team + Worker Protocol Notes
Leader-to-worker:
- Write full assignment to worker
inbox.md - Send short trigger (<200 chars) with
tmux send-keys
Worker-to-leader:
- Send ACK to
mailbox vialeader-fixedomx team api send-message --json - Claim/transition/release task lifecycle via
omx team api <operation> --json
Worker commit protocol (critical for incremental integration):
- After completing task work and before reporting completion, workers MUST commit:
git add -A && git commit -m "task: <task-subject>" - This ensures changes are available for incremental integration into the leader branch
- If a worker forgets to commit, the runtime auto-commits as a fallback, but explicit commits are preferred
Task ID rule (critical):
- File path uses
(exampletask-<id>.json
)task-1.json - MCP API
uses bare id (exampletask_id
, not"1"
)"task-1" - Never instruct workers to read
tasks/{id}.json
Environment Knobs
Useful runtime env vars:
OMX_TEAM_READY_TIMEOUT_MS- Worker readiness timeout (default 45000)
OMX_TEAM_SKIP_READY_WAIT=1- Skip readiness wait (debug only)
OMX_TEAM_AUTO_TRUST=0- Disable auto-advance for trust prompt (default behavior auto-advances)
OMX_TEAM_AUTO_ACCEPT_BYPASS=0- Disable Claude bypass-permissions prompt auto-accept (default behavior auto-accepts
+ Enter)2
- Disable Claude bypass-permissions prompt auto-accept (default behavior auto-accepts
OMX_TEAM_WORKER_LAUNCH_ARGS- Extra args passed to worker launch command
OMX_TEAM_WORKER_CLI- Worker CLI selector:

- Worker CLI selector:
OMX_TEAM_WORKER_CLI_MAP- Per-worker CLI selector (comma-separated
)auto|codex|claude - Length must be

OMX_TEAM_LEADER_NUDGE_MS- Leader nudge interval in ms (default 120000)
OMX_TEAM_STRICT_SUBMIT=1- Force strict send-keys submit failure behavior
Failure Modes and Diagnosis
Operator note (important for Claude panes):
- Manual Enter injection (
) can appear to "do nothing" when a worker is actively processing; Enter may be queued by the pane/task flow.tmux send-keys ... C-m - This is not necessarily a runtime bug. Confirm worker/team state before diagnosing dispatch failure.
- Avoid repeated blind Enter spam; it can create noisy duplicate submits once the pane becomes idle.
Safe Manual Intervention (last resort)
Use only after checking
omx team status <team> and mailbox/state evidence:
- Capture pane tail to confirm current worker state:
tmux capture-pane -t %<worker-pane> -p -S -120- If a larger-tail read or bounded summary would help, prefer explicit opt-in inspection via
before improvising extra tmux commands.omx sparkshell --tmux-pane %<worker-pane> --tail-lines 400
- If the pane is stuck in an interactive state, safely return to idle prompt first:
- optional interrupt
or escape flow (CLI-specific) once, then re-check pane captureC-c
- optional interrupt
- Send one concise trigger (single line) and wait for evidence:
tmux send-keys -t %<worker-pane> "ack + continue current task; report status" C-m
- Re-check:
- pane output via
capture-pane - mailbox updates (
or worker mailbox)mailbox/leader-fixed.json omx team status <team>
- pane output via
worker_notify_failed:<worker>
worker_notify_failed:<worker>Meaning:
- Leader wrote inbox but trigger submit path failed
Checks:
tmux list-panes -F '#{pane_id}\t#{pane_start_command}'tmux capture-pane -t %<worker-pane> -p -S -120- Verify worker process alive and not stuck on trust prompt
- Rebuild if running repo-local (
)npm run build
Team starts but leader gets no ACK
Checks:
- Worker pane capture shows inbox processing
exists.omx/state/team/<team>/mailbox/leader-fixed.json- Worker skill loaded and
calledomx team api send-message --json - Task-id mismatch not blocking worker flow
Worker logs omx team api ... ENOENT
(or legacy team_send_message ENOENT
/ team_update_task ENOENT
)
omx team api ... ENOENTteam_send_message ENOENTteam_update_task ENOENTMeaning:
- Team state path no longer exists while worker is still running.
- Typical cause: leader/manual flow ran
(or removedomx team shutdown <team>
) before worker finished..omx/state/team/<team>
Checks:
and confirm whether tasks were stillomx team status <team>
when shutdown occurredin_progress- Verify whether
exists.omx/state/team/<team>/ - Inspect worker pane tail for post-shutdown writes
- Confirm no external cleanup (
) happened during executionrm -rf .omx/state/team/<team>
Prevention:
- Enforce completion gate (no in-progress tasks) before shutdown
- Use
only for terminal completion or explicit abortshutdown - If aborting, expect late worker writes to fail and treat ENOENT as expected teardown artifact
Shutdown reports success but stale worker panes remain
Cause:
- stale pane outside config tracking or previous failed run
Fix:
- manual pane cleanup (see clean-slate commands)
Clean-Slate Recovery
Run from leader pane:
# 1) Inspect panes tmux list-panes -F '#{pane_id}\t#{pane_current_command}\t#{pane_start_command}' # 2) Kill stale worker panes only (examples) tmux kill-pane -t %450 tmux kill-pane -t %451 # 3) Remove stale team state (example) rm -rf .omx/state/team/<team-name> # 4) Retry omx team 1:executor "fresh retry"
Guidelines:
- Do not kill leader pane
- Do not kill HUD pane (
) unless intentionally restarting HUDomx hud --watch
Required Reporting During Execution
When operating this skill, provide concrete progress evidence:
- Team started line (
)Team started: <name> - tmux target and worker pane presence
- leader mailbox ACK path/content check
- status/shutdown outcomes
Do not claim success without file/pane evidence. Do not claim clean completion if shutdown occurred with
in_progress>0.
Use omx sparkshell --tmux-pane ... as an explicit opt-in operator aid for pane inspection and summaries; keep raw tmux capture-pane evidence available for manual intervention and proof.
Programmatic Team Orchestration
Use the
omx team ... CLI as the supported team-launch surface. For automation, drive the same CLI flow from scripts or supervising agents rather than relying on a separate MCP runner.
Supported current surfaces
CLI — Primary method for interactive or automated team orchestration. Use this when you want direct tmux-pane visibility or a scriptable launch path.omx team ...- Team state files — Inspect
when you need status, task, or mailbox evidence after launch..omx/state/team/<team>/
Cleanup distinction
Two cleanup paths exist and must not be confused:
(state-server): Deletes team state files on disk (team_cleanup
). Use after a team run is fully complete..omx/state/team/<team>/- tmux/session cleanup: Use the documented
shutdown / cleanup flow when you need to stop worker panes or clean up an interrupted run.omx team
Automation example
1. omx team 1:executor "fix bugs" 2. omx team status <team-name> 3. omx team shutdown <team-name> 4. Clean up the finished team state for <team-name>
Limitations
- Worktree provisioning requires a git repository and can fail on branch/path collisions
- send-keys interactions can be timing-sensitive under load
- stale panes from prior runs can interfere until manually cleaned
Scenario Examples
Good: The user says
continue after the workflow already has a clear next step. Continue the current branch of work instead of restarting or re-asking the same question.
Good: The user changes only the output shape or downstream delivery step (for example
make a PR). Preserve earlier non-conflicting workflow constraints and apply the update locally.
Bad: The user says
continue, and the workflow restarts discovery or stops before the missing verification/evidence is gathered.
