Race three agents on the same task

Running the same task across multiple agents in parallel is Orca's killer move. Same prompt, three branches, pick the winner.

Steps

  1. Create three worktrees from the same start-from ref. Name them fix-bug, fix-bug-2, fix-bug-3.
  2. Launch a different agent in each — Claude Code, Codex, Cursor CLI.
  3. Paste the same prompt into all three.
  4. Split the panes so you can see them work — drag tabs to edges.
  5. When they finish, review each diff. Use Annotate AI Diff on the winner.
  6. Commit, push, open PR from the winning worktree.
  7. Delete the two losers — one click removes the worktree and branch.

Why it works

Different agents make different mistakes. Running the same task in parallel is cheaper than sequential retries and surfaces disagreement as a signal. Where three agents agree, the answer is probably right. Where they split, you've found the hard part.
