Summary
- Drive any artifact to convergence by alternating two genuinely different LLM reviewers — a Codex reviewer and an independent Claude review subagent — applying each round's findings and looping until BOTH independently agree it clears the bar (default: no critical/high findings).
- Artifact-agnostic: works on a plan, PRD, design doc, spec, or implementation diff.
- Use whenever the user says 'have two LLMs converge on this', 'loop Claude and Codex until they agree', 'review and revise until consensus', 'iterate this plan/PRD/spec until there are no blockers', or wants cross-model agreement rather than one reviewer's opinion.
- Prefer this over a single review pass whenever the user wants different models to actually agree on an end result.
- NOT pr-autopilot (one GitHub PR's comment threads) — this is the artifact-agnostic, alternating-different-models, iterate-to-consensus loop.
