Orchestrate OpenAI Codex from Claude Code through a shared file relay — turn-based prompts and handbacks in .ccx-harness/relay.md, each agent polling on its own cadence, with merges gated behind an independent three-reviewer verification.

Claude plans features with you, then orchestrates OpenAI Codex through a shared file relay: both agents read and write .ccx-harness/relay.md on their own polling cadences (no computer use anywhere), with conversational planning, 85-90% coverage targets, a PR-based workflow, and an independent three-reviewer verification gate with auto-merge on convergence.
