Anthropic has released its new model, Opus 4.8, together with a new feature it calls Dynamic Workflows. This lets Claude Code orchestrate dozens to hundreds of parallel subagents to tackle complex, multi-stage coding tasks end-to-end.

When you trigger a workflow (either by asking Claude directly with the word “workflow” or enabling “ultracode” mode), Claude plans the work dynamically, distributes tasks across subagents, and uses verification agents to check findings from independent angles.

Here’s some practical use cases for product teams to consider:

• Codebase-wide bug hunts - run parallel searches across a service, then have independent agents verify each finding before surfacing real issues in a report

• Large migrations - port codebases across frameworks, deprecate APIs, or change languages across thousands of files with coordinated parallel execution

• Managing A/B tests - Claude’s head of product Cat Wu says she recently used this new feature to catalogue 100s of A/B test flags and deprecate stale ones. Instead of waiting for Claude Code to investigate each one sequentially, dynamic workflows allowed her to do them all in parallel.
