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 "v2 run" handles are scaffolded but never created

Not switched on
Useful1 Signal3
Workflows

Workflow records can hold a newer run handle, but nothing ever creates one here.

v2 workflow run handles and schema extensions are scaffolded but the provider returns nothing.

What

Workflow task records can now hold a v2 run handle that gets killed when the workflow is stopped, and the workflow tool's output schema is meant to absorb extra fields from a provider. That provider compiles to a bare return;, so no extra fields are added and no v2 run is ever created here.

Evidence

runOpOutputFields

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