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 pattern-matching words and a budget-starvation protocol

Under the hood
Useful2 Signal3
Workflows

Workflow pattern matching gained variable binding and count matching, and starved agents now wait for budget.

What

The workflow sandbox gained two pattern-matching words, one that binds a variable and one that matches at least N items, each with its own validation error, and rule callbacks now receive the bindings as a second argument. Separately, an agent whose run has exhausted its budget is parked as starved and waits for more instead of failing.

Details
  • A starved agent resumes when a budget top-up arrives; the message tells the model to put {topic:'budget', units:N} to continue.
  • Starved rows are surfaced in the workflow status report.
  • All of this lives in the Workflow tool, which is only registered when it is present in the build.
Evidence

put {topic:'budget', units:N} to continue

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