Currently we're mostly working on separate issues or aspects, so not much context sharing needed. We have some skills that we share in a shared network directory.

As for why using both instead of OpenCode or similar, well, subscriptions take you a long way for not very much. Also security is a thing here now so sec guys feel more comfortable with big names rather than "random" open source.

Opencode and other harnesses like Pi do support codex and claude(for now) subscriptions, but the point about security makes sense.
