Anthropic Launches Dynamic Workflows for Claude: Orchestrate 1,000 Parallel Agents to Boost Bug Detection
Anthropic has introduced dynamic workflows in Claude Managed Agents, enabling the parallel orchestration of up to 1,000 sub-agents per execution. A lead agent plans and distributes tasks, merging results to achieve significantly higher bug detection rates in large codebases compared to single-agent runs, though token efficiency remains a point of debate.

Anthropic is adding dynamic workflows to its Claude Managed Agents, bringing multi-agent orchestration to the platform. The managed agent infrastructure has been around for a while, but dynamic workflows are new. A lead agent creates a plan, distributes tasks to sub-agents, and merges the results when they're done. Up to 1,000 agents can run in parallel per execution.
Video 3 Whether this is cost-effective seems debatable. A senior OpenAI engineer recently called agent swarms a massive waste of tokens, but Anthropic points to its own testing: The team hid 70 bugs in a 116,000-line codebase and found that a single agent caught between 14 and 27 per run, while the dynamic workflow consistently hit 66. Whether those gains hold across different task types remains to be seen, so, as always, it's worth testing with your own workloads.
To activate dynamic workflows, select the "multiagent_20261001" agent type. Because these workflows can burn through "a lot of tokens," Anthropic recommends starting small. You can get going through the documentation or by running "/claude-api managed-agents-onboard" in Claude Code.
