Runs an adversarial debate: N champion teammates argue and challenge each other via direct messaging, then a synthesizer subagent analyses the settled debate and delivers a recommendation.

Step 1 — Establish options

Build the option list from user input, inference, or a combination:

User-specified: use exactly as provided
Propose: generate 3–5 candidate options for the topic; present and let the user confirm, add, or remove
Hybrid: merge user-supplied options with agent-proposed additions; present the merged list

Always display the final option list and ask for confirmation before spawning any agents.

Guard the option count: fewer than 2 options → tell the user a round-table needs at least 2 options and stop. Exactly 2 options → note this is a direct comparison and omit "consensus" framing from the synthesizer prompt.

Step 2 — Spawn champion team

Create an agent team with one champion teammate per confirmed option. Run champions on a fast mid-tier model — the debate needs breadth and speed, not peak reasoning per turn.

Each champion receives:
