Teammode

Run a named team of cooperating Codex workers under one leader, with durable state on disk. This is a Codex-only workflow. It never depends on an external terminal runner - it coordinates through Codex's own collaboration tools plus a bundled state script, on ONE of two transports chosen up front: native MultiAgentV2 agents, or Codex App threads as the fallback.

When to use a team (and when to use plain subagents instead)

Use a TEAM when EITHER holds:

• the work does NOT split into perfectly isolated pieces, but doing it in parallel is clearly more convenient - members will need to see and react to each other's findings; or
• one task still needs exploration, yet its GOAL is already clear - parallel investigation under a fixed objective.
