Dynamic Workflows in Claude Code: When the AI Writes Its Own Orchestration

Most of us still build our agent workflows by hand: send a prompt, copy the output, paste it into the next prompt, correct, repeat. With Dynamic Workflows, Anthropic inverts this pattern — Claude writes the orchestration itself. An assessment of what changes technically and when the effort is worthwhile.

The Real Turning Point Is Hidden in an Example

Jarred Sumner ported the JavaScript runtime Bun from Zig to Rust. Roughly 750,000 lines of Rust, 99.8 per cent of the existing test suite passing, eleven days from the first commit to the merge. Not by hand, and not in a long pair-programming session with Claude, but using Dynamic Workflows — the orchestration feature that Anthropic released on 28 May 2026 alongside Claude Opus 4.8 as a Research Preview.
