    OpenAI Codex's agent guardrails represent a maturation of AI coding tools. The decision to limit sub-agents to 6 max isn't just about resource management—it's about preventing the chaotic fan-out behavior that can make AI assistance unpredictable. Combined with the new network sandbox proxy, OpenAI is clearly prioritizing controlled, secure AI interactions over raw capability. This mirrors broader industry trends toward "responsible AI" in development environments, where reliability often trumps raw power.
