Anthropic shipped dynamic workflows that let Claude spin up tens to hundreds of parallel subagents in one session, the most powerful feature yet for large-scale code tasks. Users on Max, Team or Enterprise plans open the CLI, Desktop or VS Code extension, enable Auto Mode via shift+tab, then either prompt "Create a workflow for [task]" or activate Ultracode to trigger automatic high-effort runs; Claude breaks work into subtasks, verifies outputs and returns a single result. The feature targets codebase audits, hundred-file migrations and any work needing independent checks, compressing quarter-long projects into days while the AI industry impact accelerates enterprise automation.
