Claude Code Dynamic Workflows: parallel subagent orchestration in research preview

Category: Agentic coding
Status: confirmed
Sources: Anthropic announcement, Claude Code docs, Claude Opus 4.8 release
Summary: Anthropic shipped Dynamic Workflows for Claude Code on 2026-05-28 as a research preview alongside Claude Opus 4.8, with general availability announced 2026-06-02. The feature lets Claude write JavaScript workflow scripts at runtime, break a task into subtasks, fan them across parallel subagents, verify results, and return a single coordinated output. Use cases include codebase-wide bug hunts, security audits, and large-scale migrations. Jarred Sumner reported porting roughly one million lines of Zig to Rust in six days using the feature. Availability is currently limited to Max, Team, and Enterprise plans and the Claude API; Claude Code CLI, Desktop, and VS Code extension are all supported.
Why it matters: Teams with codebase-wide or multi-file tasks that exceeded single-agent context can now run them as verifiable parallel work inside Claude Code without building custom orchestration.
