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 agents that finish with no result now fail loudly

You'll notice
Useful2 Signal2
Workflows

A workflow agent that finished with nothing now raises a clear error instead of passing an empty result on.

What

In workflow v2 runs, an agent that was skipped, blocked, or gave up after retries used to pass its empty result along as a value. It now raises a descriptive error instead.

Details
  • Cleanup also sweeps retracted setup-script facts along with failed and finished ones.
Evidence

agent produced no result (skipped, blocked, or gave up after retries)

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