Delegate-first Codex orchestration for coding, debugging, review, planning, research, migration, audit, testing, documentation, or any task that benefits from routing work to subagents. The root agent acts as dispatcher, escalation controller, synthesizer, and final senior reviewer. Delegate substantive work by default, continuously reassess delegation, use explicit model routing plus reasoning effort, support custom-agent and built-in-agent runtimes, escalate stuck work narrowly, and require root-level final review before completion. Avoid only for pure conversational micro-answers or when the user forbids subagents.
