multi-llm-convergence

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.
