Based on SOC occupation classification
Query OpenAI Codex (GPT-5.2-codex) for second opinions, alternative implementations, or specialized knowledge. Use when you want to consult another AI model, need a different perspective on a coding problem, or want to verify an approach.
Verify GSD setup - checks Claude, Codex, skills, and MCP servers are working correctly.
Run entire milestone autonomously with Codex validation. Auto-detects current milestone, executes all phases, and runs audit.
Autonomous phase execution with Codex validation. Runs plan/execute/verify cycles in a bash loop until done or halted.
