Agent Skills: OMC Teams Skill

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)
• Classic tmux session optional for in-place pane splitting ($TMUX set). Inside cmux or a plain terminal, omc team falls back to a detached tmux session instead of splitting the current surface.
• 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 is set, omc team can reuse the current tmux window/panes directly.
• If $TMUX is empty but CMUX_SURFACE_ID is set, report that the user is running inside cmux. Do not say tmux is missing or that they are "not inside tmux"; omc team will launch a detached tmux session for workers instead of splitting the cmux surface.
• If neither $TMUX nor CMUX_SURFACE_ID is set, report that the user is in a plain terminal. omc team can still launch a detached tmux session, but if they specifically want in-place pane/window topology they should start from a classic tmux session first.
• If you need to confirm the active tmux 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 | Requested in-place pane topology from a non-tmux surface | Start tmux and rerun, or let omc team use its detached-session fallback | | cmux surface detected | Running inside cmux without $TMUX | Use the normal omc team ... flow; OMC will launch a detached tmux session | | 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 |
