#subagents

OpenAIDevs said on March 16, 2026 that subagents are now available in Codex. The feature lets developers keep the main context clean, split work across specialized agents, and steer individual threads as they run, while the official docs already describe PR review and CSV batch fan-out patterns.

GitHub used X on March 15, 2026 to spotlight the Copilot CLI `/fleet` command for routine maintenance work. GitHub’s official Copilot CLI materials now describe `/fleet` as a parallel sub-agent workflow that converges multiple runs into one decision-ready result.
