Claude Code Dynamic Workflows (Research Preview)

A Claude Code feature in research preview where Claude writes a script to run hundreds of subagents in parallel on one large task, then checks the results before showing you.

Details

  • Claude writes a JavaScript orchestration script for the task you describe, and a runtime runs it in the background while your session stays usable
  • Runs tens to hundreds of parallel subagents in a single session and checks its own work before reporting back
  • Used internally for codebase-wide bug hunts, security audits, and optimization passes, with independent verification on each finding
  • Start it by asking Claude to create a workflow, or turn on a new ultracode setting that lets Claude decide when to use one
  • Available now in research preview in the Claude Code CLI, Desktop, and VS Code extension, plus the Claude API, Amazon Bedrock, Vertex AI, and Microsoft Foundry

Best for

Huge tasks one chat cannot hold, like a migration or a bug hunt across hundreds of files.

When to use it

The work splits into many independent pieces that can run at once and need verifying.

Who benefits

Developers and engineering teams on Claude Code Max, Team, or Enterprise plans.
