GitHub project orchestrates Codex with Astra as planner and Luna subagents
TheMoonMidas · x · 2026-09-07
Developer melvindvivas updated the open-source project codex-astra-luna-orchestrator (229 stars): a Codex setup where GPT-6 Astra acts as root orchestrator and reviewer while GPT-5.6 Luna is pinned as the default model for execution subagents.
- Configured via .codex/config.toml: main model gpt-6-astra (reasoning effort low), agents enabled, up to 4 concurrent subagent threads per session, subagents default to gpt-5.6-luna (medium).
- Each role (explorer/worker/tester/reviewer/researcher) has its own toml pinning the intended model: Luna handles exploration, execution, testing and research; Astra handles review.
- Ships with an astra-orchestrator skill, AGENTS.md, and setup.sh/setup.ps1 installers. The update enforces Luna usage more strictly for research and exploration tasks.
