Claude Code Workflows

A dynamic workflow is a JavaScript script that orchestrates subagents at scale. Claude writes the script for a task you describe, a runtime executes it in the background, and only the final answer returns to your conversation. The script — not Claude's context — holds the loop, the branching, and the intermediate results, so one run coordinates tens to hundreds of agents instead of the few a single turn manages.

Status: research preview, Claude Code v2.1.154+. Available on paid plans (Pro toggle in /config; Max, Team, Enterprise) and via the Anthropic API, Amazon Bedrock, Google Cloud Vertex AI, and Microsoft Foundry.

When to use a workflow

Reach for a workflow when fan-out exceeds one turn, when the orchestration itself must be repeatable, or when work needs independent verification passes before results reach you. Examples: a codebase-wide bug sweep, a 500-file migration, research that cross-checks sources, or a hard plan drafted from several angles before commitment.

Use a single subagent (the Agent tool) for one-off delegated work whose result lands directly in your context. Use a skill for instructions Claude follows inline. Use a workflow when neither scales.
