Codex Subagents – Parallel custom agents for complex coding workflows

Summary: Codex Subagents enable spawning specialized, parallel AI agents with isolated roles to handle complex coding tasks. This allows multi-step workflows without losing context by assigning distinct instructions, models, and tools to each subagent, then merging results cleanly.

What it does

It creates custom TOML-defined subagents for tasks like exploration and review, running them in parallel to manage multi-step coding processes efficiently.

Who it's for

Developers and teams needing to coordinate complex coding workflows involving multiple specialized AI roles.

Why it matters

It prevents context loss and clutter in the main thread by isolating task-specific agents, improving workflow clarity and speed.
