Codex Sol/Astra Orchestrator + Luna Subagents

Install a Codex profile with GPT-6 Astra, GPT-6.1 Sol, or GPT-6 Luna as the orchestrator, GPT-6 Luna execution subagents, and an independent reviewer.

The Sol profiles use gpt-6.1-sol for both the orchestrator and reviewer.

Orchestration topology

The diagram shows the Astra (Pro) and Sol orchestrators. Plus uses a Luna root, as shown in the profile table below. Execution roles use GPT-6 Luna; the reviewer uses Astra for Pro/Plus and Sol for Sol profiles.

Setup

1. Clone this repository and enter it:

   git clone https://github.com/donvito/codex-astra-luna-orchestrator.git
   cd codex-astra-luna-orchestrator
   

2. Run the installer for your platform:

   macOS/Linux:

   ./setup.sh
   

   Windows PowerShell:

   powershell -ExecutionPolicy Bypass -File .\setup.ps1
   

   PowerShell 7:

   pwsh -File .\setup.ps1
   

3. When prompted, enter an existing target repository other than this one, choose a profile by number or name (Enter selects Pro), and confirm which components to install. For example:

   Target repository path: ../my-project
   Select Profile [1-6] (default 1): 5
   

The installer copies the selected configuration to .codex/, its skill to .agents/, and project instructions to AGENTS.md. Existing component files are updated only after confirmation; existing AGENTS.md content is preserved. Codex loads project-scoped configuration only for trusted projects.

Installed target project

If you install all three components into ../my-project, the installer adds these paths alongside the project’s existing files:

my-project/
├── .codex/
│   ├── config.toml
│   └── agents/
│       ├── explorer.toml
│       ├── researcher.toml
│       ├── reviewer.toml
│       ├── tester.toml
│       └── worker.toml
├── .agents/
│   └── skills/
│       └── astra-orchestrator/
│           └── SKILL.md
└── AGENTS.md

profiles//codex/ becomes .codex/, and profiles//agents/ becomes .agents/. The root AGENTS.md is copied to the target, or its instructions are appended if that file exists.

How to use the skill

From the target repository, launch Codex CLI. For the example above:

cd ../my-project
codex

For complex work, Codex may select the skill automatically, or you can invoke it explicitly:

$astra-orchestrator
Implement the invoice export endpoint. Use the explorer to map the path,
a worker to implement it, and the tester and reviewer to verify it.

The skill keeps the astra-orchestrator name in every profile so the shared AGENTS.md works; the Sol profiles use Sol according to their configuration.

Profiles

All models above are GPT-6. Execution roles are explorer, worker, tester, and researcher; named roles pin their models and reasoning levels independently of the default subagent settings. Each ready-to-copy profile lives under profiles//.

For manual project setup, copy the selected profile’s codex/ and agents/ to the target repository as .codex/ and .agents/, and add this repository’s AGENTS.md. For personal/global setup, copy its codex/agents/ into ~/.codex/agents/, its agents/skills/astra-orchestrator/ into ~/.agents/skills/, and merge, rather than replace, its codex/config.toml settings into ~/.codex/config.toml. Do not overwrite other existing Codex settings.
