Bigger teams benefit from both. * **Review Agent vs Security Engineer**: the Review Agent is the generalist second opinion across any artifact; the Security Engineer goes deep on vulnerabilities and compliance. * **AI Engineer vs ML Engineer**: AI Engineer builds with LLMs (prompts, RAG, agents); ML Engineer evaluates and trains models. Every skill mentioned here is described one-by-one in the [skills catalog](/reference/skills-catalog).
