Claudex skill — Claude and GPT-6 Astra cross-audit plan and build

There's a new free skill that makes Claude and GBD6 Astra work on the same task together. It's called Claudex, and instead of trusting one model to plan, build, and then judge its own work, it splits the job between both models. First, Claude writes the plan, then GBD6 Astra audits it. They keep going until the plan actually holds up. Then what they do is they switch roles. Astra builds the project, and Claude audits the implementation. So you're no longer letting one AI guide its own homework. You've basically got two frontier models constantly challenging each other before anything is finished. And because it runs as a skill, you can drop it straight into Claude or Codex and reuse the workflow whenever you build. So just comment Claudex, and I'll send you the skill.
