From One Agent to a Team: Understanding Codex Subagents

Complex tasks can be divided among specialized AI agents, called subagents, within the Codex CLI. Users can define these specialist agents using TOML configuration files to handle specific parts of a problem. A main agent then orchestrates the workflow, delegating tasks to the subagents and synthesizing their individual findings into a final, comprehensive response. This multi-agent pattern is demonstrated with a travel planning example where logistics, budget, and experience agents collaborate to produce a recommendation.
