I vibe coded bukowski [1] to circumvent the Claude Code scrollback bug... then added support for codex and gemini in multiple panes... then an MCP server for them to chat with each other. I usually ask them to comment on the plan and brainstorm before a Claude instance commits to implementation, then the others review. Sometimes even two Claudes come to different conclusions or refine each others ideas, Codex is great at finding edge cases or non obvious bugs.
