Since you asked, the answer is that I built and use an agent multiplexer called Clor https://clor.com

I have a $200/mo Claude subscription and a $200/mo Codex subscription, and I'm signed in to both. The Docker containers keep each session isolated, so dev servers, browser testing, etc. can work without conflicts.

It includes `/ask-claude` and `/ask-codex` skills that I use very frequently to have the Claude or Codex harness call out to the other one for advice on plans, bug repro, code review, etc.

The agents run in total "yolo" mode, so there are no permission prompts to approve. The risk is mitigated by the Docker containers (which don't necessarily provide a security barrier but do limit accidents).

I was doing this manually in Ghostty tabs for a long time, and it got painful, so I built a much more sophisticated version that I (and my friends/colleagues) could use.

I have a slightly jankier setup.

Generally using Claude Code with Fable 5.1 (high) to plan and implement (Opus 5 (medium) as the implementer subagents), and using Codex with Astra high to review the plan and review the implementers' output.

Using the OpenAI codoex plugin thingy:
