DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Workflow prompt drops its pipeline code sample

You'll notice
Useful2 Signal1
Workflows

The workflow tool's guidance dropped its long example; the concurrency limits are the same.

What

The concurrency guidance for the workflow tool lost its long multi-stage example and reordered the surrounding text. The limits it describes are unchanged: at most 16 or available CPUs minus 2, whichever is smaller, and 1000 agents per workflow.

Evidence

that middle transform doesn't need the barrier. Rewrite as a pipeline with the transform inside a stage. When in doubt: pipeline.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
