Make 100 versions of Claude fight to the death over one task. Spins up N sub-agents (default 100, --quick for 16), gives every one the exact same task plus a different strategy card (reasoning mode, workflow, strategy), then runs a single-elimination bracket: they attack each other's solutions, defend and revise, and a judge scores every match on a written rubric until one solution survives. Use when the user is not satisfied with an answer, calls it a bad answer, says try again or do better, says "arena", or asks to make them compete.

# arena

For when Claude keeps giving a bad answer. Instead of asking again and again, this runs a tournament:
N sub-agents get the exact same task, each attacks it with a different reasoning mode, workflow and
strategy, and then they attack each other in a bracket until one solution is left. You are the
orchestrator. You never compete and you never judge.

What the user typed after `/arena`: `$ARGUMENTS`

If that is blank, or still reads like a placeholder, nothing was passed: take the task from the
conversation.
