OMC Teams Skill

Spawn N CLI worker processes in tmux panes to execute tasks in parallel. Supports claude, codex, and gemini agent types.

/omc-teams is a legacy compatibility skill for the CLI-first runtime: use omc team ... commands (not deprecated MCP runtime tools).

Usage

/oh-my-claudecode:omc-teams N:claude "task description"
/oh-my-claudecode:omc-teams N:codex "task description"
/oh-my-claudecode:omc-teams N:gemini "task description"

Parameters

N - Number of CLI workers (1-10)
agent-type - claude (Claude CLI), codex (OpenAI Codex CLI), or gemini (Google Gemini CLI)
task - Task description to distribute across all workers

Examples

/omc-teams 2:claude "implement auth module with tests"
/omc-teams 2:codex "review the auth module for security issues"
/omc-teams 3:gemini "redesign UI components for accessibility"

Requirements

tmux binary must be installed and discoverable (command -v tmux)
Active tmux session required to launch worker panes ($TMUX set, or start/attach tmux first)
claude CLI: npm install -g @anthropic-ai/claude-code
codex CLI: npm install -g @openai/codex
gemini CLI: npm install -g @google/gemini-cli

Workflow

Phase 0: Verify prerequisites

Check tmux explicitly before claiming it is missing:

command -v tmux >/dev/null 2>&1

If this fails, report that tmux is not installed and stop.
If tmux exists but $TMUX is empty, report that the user is not currently inside an active tmux session. Do not say tmux is missing; tell them to start or attach tmux, then rerun.
If you need to confirm the active session, use:

tmux display-message -p '#S'

Phase 1: Parse + validate input

Extract:

N — worker count (1–10)
agent-type — claude|codex|gemini
task — task description

Validate before decomposing or running anything:

Reject unsupported agent types up front. /omc-teams only supports claude, codex, and gemini.
If the user asks for an unsupported type such as expert, explain that /omc-teams launches external CLI workers only.
For native Claude Code team agents/roles, direct them to /oh-my-claudecode:team instead.

Phase 2: Decompose task

Break work into N independent subtasks (file- or concern-scoped) to avoid write conflicts.

Phase 3: Start CLI team runtime

Activate mode state (recommended):

state_write(mode="team", current_phase="team-exec", active=true)

Start workers via CLI:

omc team <N>:<claude|codex|gemini> "<task>"

Team name defaults to a slug from the task text (example: review-auth-flow).

After launch, verify the command actually executed instead of assuming Enter fired. Check pane output and confirm the command or worker bootstrap text appears in pane history:

tmux list-panes -a -F '#{session_name}:#{window_index}.#{pane_index} #{pane_id} #{pane_current_command}'
tmux capture-pane -pt <pane-id> -S -20

Do not claim the team started successfully unless pane output shows the command was submitted.

Phase 4: Monitor + lifecycle API

omc team status <team-name>
omc team api list-tasks --input '{"team_name":"<team-name>"}' --json

Use omc team api ... for task claiming, task transitions, mailbox delivery, and worker state updates.

Phase 5: Shutdown (only when needed)

omc team shutdown <team-name>
omc team shutdown <team-name> --force

Use shutdown for intentional cancellation or stale-state cleanup. Prefer non-force shutdown first.

Phase 6: Report + state close

Report task results with completion/failure summary and any remaining risks.

state_write(mode="team", current_phase="complete", active=false)

Deprecated Runtime Note

Legacy MCP runtime tools are deprecated for execution:

omc_run_team_start
omc_run_team_status
omc_run_team_wait
omc_run_team_cleanup

If encountered, switch to omc team ... CLI commands.

Error Reference

Error	Cause	Fix
`not inside tmux`	Shell not running inside tmux	Start tmux and rerun
`Unsupported agent type`	Requested agent is not claude/codex/gemini	Use `claude`, `codex`, or `gemini`; for native Claude Code agents use `/oh-my-claudecode:team`
`codex: command not found`	Codex CLI not installed	`npm install -g @openai/codex`
`gemini: command not found`	Gemini CLI not installed	`npm install -g @google/gemini-cli`
`Team <name> is not running`	stale or missing runtime state	`omc team status <team-name>` then `omc team shutdown <team-name> --force` if stale
`status: failed`	Workers exited with incomplete work	inspect runtime output, narrow scope, rerun

Relationship to `/team`

Aspect	`/team`	`/omc-teams`
Worker type	Claude Code native team agents	claude / codex / gemini CLI processes in tmux
Invocation	`TeamCreate` / `Task` / `SendMessage`	`omc team [N:agent]` + `status` + `shutdown` + `api`
Coordination	Native team messaging and staged pipeline	tmux worker runtime + CLI API state files
Use when	You want Claude-native team orchestration	You want external CLI worker execution
