claude-codex-loop orchestrates a structured collaboration loop between Claude Code (designer/reviewer) and OpenAI Codex (auditor/implementer). It runs two stages — design and code — each with up to 5 rounds of iterative review plus an independent validation pass. How it works: - Brainstorming (optional) — Explore requirements interactively before designing - Design stage — Claude Code writes a spec, Codex audits it independently each round until convergence - User gate — You review and approve the design before any code is written - Code stage — Codex implements, Claude Code reviews the full diff each round - Independent validation — A separate audit pass with zero prior context to catch groupthink All work happens on a dedicated branch.
