Orchestrate a parallel multi-agent build with mandatory cross-review across Claude and Codex. Splits a multi-component coding task into ~equal Claude and Codex subtasks, runs them in parallel in isolated git worktrees, then has the OPPOSITE model review each diff before consolidation. Use for multi-file features, refactors with parallel slices, batch fixes, or audit-and-fix passes — bail to a single-agent build for trivial changes. The cross-review is the value: different model families catch different bug classes.
