Summary

The creator shares an open-source setup for Codex. Astra or Sol acts as the orchestrator, and Luna models run as subagents. Profiles assign models and reasoning levels to roles (like reviewer), and you can ask your agent to create new combinations.

Key points

• Use Astra or Sol as the orchestrator and Luna for cheaper subagents.
• The default profiles cover Codex Pro and Plus plans.
• You can ask your agent to generate new profile combinations.
• The creator is considering setting the Pro Astra reviewer to high/xhigh reasoning.
• Even Astra on low has caught issues in code review so far.
• Fork the repo and adapt it to your plan and workflow.
