Keep backend implementation and integration under Codex ownership while delegating a bounded frontend slice to the local Claude Code CLI through a durable, bidirectional backlog. Use for full-stack work where Codex owns APIs, SQL, migrations, and backend contracts and Claude owns web UI; when a Codex-to-Claude or Claude-to-Codex session must survive token or execution outages; or when the user asks either model to resume a prior delegation.
