Claude Code Dynamic Workflows: Run Hundreds of Parallel Subagents

Anthropic shipped Dynamic Workflows alongside Claude Opus 4.8, letting you orchestrate up to 1,000 subagents (16 concurrent) from a single JavaScript script that Claude writes for you. The key architectural insight: the orchestration plan moves into code rather than Claude's context window, so intermediate results live in script variables and Claude only holds the final answer — dramatically reducing context bloat on large codebase migrations. Requires Claude Code v2.1.154+ and is available to Enterprise, Team, and Max users.
